New install - Python install issue with Raspberry Pi image "Bullseye" about airiana HOT 78 CLOSED

Thanks for taking your time to fix the migration and for a great software.
The documentation for installing Airiana are confusing:

-Update the latlong.json file with your position to enable the forcast for your position.

I says the user must update latlong.json file, but I do not find the file.

-edit the ip-config file.

I think it should be renamed to ipconfig file in the Airiana folder.

Hi, actually I was unaware, thought I had recovered from strange path handling backwards compat issues when removing the use of pathlib, I was misstaken, A fix is up now which runs on my unit, give it a spin. =) commit: c127b35

from airiana.

Hi, good to see we're making some progress. It looks like there is some kind of communications issue with the IAM, I found a bug where a zero len string response is considered as a passing communication test that is now fixed as of commit 24d3d32. Can you verify that the IAM module can accept connections and is responding? A note on using the log files; they are not executable use "cat RAM/err" and "cat RAM/error_rate" to see content.

I added a simple RTU/TCP test to request.py to simplify testing, sudo ./request.py now give a printout of the initial setup and subsequent selftest of communication to indicate if it is to use the savecair address space or the old legacy one. You can use it to test communication with your unit. commit c5ba153

note that if you manually change the name of the directory you will need to remove the systemd files and update all static paths; run the install script again with the clean argument sudo python3 install.py clean to reset some static paths and replace the systemd files (its in my backlog to make all paths relative).

Regarding control, you will be able to control the unit from your LAN it is only WAN access that is limited, it can be done but needs some port fwd magic other than just exposing port 80.

Nice, progress, I can recomend using the mqtt option to integrate with homeAssistant, gives out more entities.

however, it seems the it does not set new fanspeed values, I’ll see if I can add some more verbosity to the log. I just see that it tries to set a new fanspeed but it fails for some reason.

from airiana.

How do you send the json file with mqtt publish to home assistant from the raspberry pc? My Home assistant pc have Eclipse Mosquitto broker already.
I added this in my crontab file:

* * * * * mosquitto_pub -t airiana -f Airiana/RAM/air.out

as mosquitto is running on my pi I have not defined the broker only the topic and file where the json data is.

here's my homeAssistant configuration:
configuration.txt
I was not allowed to attach it with .yaml extension hence the .txt

I have a new commit up with some retry logic on TCP writes. commit: fbaf77a

from airiana.

added fixes for cmd.py and air.out, seems I broke the json prints last night. commit : f1b44c7
also found a bug in the write function that is a probable cause of the fanspeed set to be failing

When in summer mode the exchanger will stop after a little while. You can see exchanger mode flip from 5 to 0.

Something is up with offset to zero should only print once.

Great to hear things are working, yes I had to do some changes to the graph, not sure why but the border was hiding the temperature legend. I had not changed anything so I suspect some dependencies in matplotlib to be the cause.

from airiana.

Not sure about the cause of this but it seems the extract temp is 0 again. This will explain RH above 100% if temp outside is higher than 0. The log ends on the 22:nd and it looks strange at the end with regards to the extract temp. Maybe you can run ./backup.py to get the last 25hrs from RAM into the data.log file before posting to have it include the latest data. Airiana does this intermittently to save on SD-card writes and it is kind of wierd I agree.

from airiana.

tnx for reporting now fixed properly, was a mistake on my part.

from airiana.

Hi, data type is correct as it works most of the time, any issues with sign bit will be seen if extract temp would be lower than 0 and then as a twos complement. However I had some ideas reading thru the modbusTCP documentation on what would happen if there is a loss of connection mid the communication cycle. Did not howver become any smarter but added Auto close festure on the connection to reconnect after each request along with some more error prints. New commit up…

from airiana.

i just found an edge case where this might apply, where if the IAM will supply 2 consecutive zero values it may lock further extract temp updates, as this is what we are seeing try the latest commit. Note that i found an error in the shutdown fnction aswell so recomended is a ”kill” on the process to properly get it to restart.

from airiana.

You may absolutly lower the baud rate, I run 19200, and as the IAM uses TCP onetime connections no high speed comm is needed, I’d estimate around 10request/s, slower is always more robust. I did anpther commit with a larger tolerance for bad temp data may save the correct samples that got reported as errors. Lets break this bug, try to lower the baudrate and lets see if we get less bad values.

from airiana.

Good to hear you found the culprit. Lets keep it running a few days to be sure before I remove to much debug code. I’ll read up on eco mode to see what it does.

from airiana.

done, the power consumed calc avail as printout and in json data as "electricPowerTotal" give it a spin.
I will look into the other request as time is available.

Corrected the caculation it was wrong and note that the power unit is in Wh

Started work on a full python3 migration, thanks for taking the time to add issues about the fact that the os baseline now has left py2.7 behind.

from airiana.

If you'd like to test stuff out while I debug. there is a branch avail called python3-migration. This should work fully on python3 only systems. =)

from airiana.

Great. I am going to install python3-migration this weekend.

seems it does not create the files due to a permission issue, I updated the service files in the repo to execute as root user instead of pi, you can manually edit the user in file /etc/systemd/system/airiana.service and /etc/systemd/system/controller.service.
manual execution of the core is also available for testing by using sudo ./airiana-core.py unitll I can figure out how to close the gap with regards to not having the ram drive mount with root ownership.

from airiana.

Thanks. I going to try execute as root.

from airiana.

Thanks for your work to migrate to Python3. This is a status update with the newest git update. I think you know about this, but starting as root gives errors:

Airiana webpage is now running.
First the the webpage was not running. I got some warning about path not found in line 3 in ip-replace.sh. I renamed the downloaded git zipfolder from "Airiana-python3-migration" to "airiana". Then the webpage worked.
I did the install again "sudo python ./install.py" in the airiana folder. The RAM folder was created without error. So it seems the correct name worked for the install script also.

The webpage is only for local access. How can I get remote access to the webpage from my LAN?
*No access allowed outside of local domain.

from airiana.

Started with a fresh install raspbian desktop. Downloading Airiana-python3-migration and unzipping. The folder is not renamed. Installed airiana with sudo ./request.py
Edited ipconfig with {"ip":"10.0.0.107", "port":505} and airiana.service
with "TCP".

Do not now if it helps, but I use TCP port 505 with Home Assistant:
modbus:

• type: tcp
  host: 10.0.0.107
  port: 502
  name: "VTR500"
  Here is a link to the IAM access module I use. https://makitech.no/ventilasjon/boligaggregater/tilbehor-til-boligaggregater/internett-tilgangsmodul-for-SAVECair-aggregater#intro

from airiana.

First I'd like to thank you for helping me with debugging this, it turned out to be quite the handful to migrate, but necessary
I'm a little bit confused on what exactly happened here, seems you start with RTU and with incorrect paths. anything saying RTU should be bad in your case. we want the request class to talk TCP with the IAM.
paths are made correct when you exec the install.py script
If you test with sudo ./airiana-core.py, remember to add TCP as an argument. sudo ./airiana-core.py TCP
I suggest this install procedure

• git clone https://github.com/BeamCtrl/Airiana.git
• cd Airiana
• git checkout python3-migration
• sudo python3 install.py clean ( this command when used with clean removes the systemd files and reinstalls them after path replacements to match install path you will however need to re edit and add the TCP argument to core execution)
• edit "/etc/systemd/system/airiana.service" add TCP to arguments
• add your TCP config, please check if port 502 or 505 is the correct one, saw you used both above.
• test with ./request.py, you should see

pi@airiana:~/airiana $ ./request.py

But with the TCP Comm test passing, I have it connected thru RTU.

Thanks for your kind words. I started with a fresh raspbian desktop install and then after configure and update the operativsystem followed your procedure for installing Airiana.
Then I tested the communication with IAM (ip 10.0.0.107) with the tcp port 505 and 502 with request.py. I sorry to say that both test was not sucessfull.

I think I was a little quick with the feedback. The communication with the IAM works now after changing the port to 502. When using tcp 505 the airiana service fails.

Can you paste the output from ./watch or the content of ./RAM/out?
you can get low level controll by ./cmd.py, it bypasses the http server for controlls.

Looking at the errors above, has it created a latlong.json file with your position?

from airiana.

Airiana has not created a latlong.json file.

I start up ./cmd.py and use the menu

Nothing happens with the systemair VTR500 fans when I choose 10: "Toggle shower mode" or 8: "Run fans for 120 min at Max"

from airiana.

We’re closing in… you have confirmed comms. It is crashibg because it tries to geolocate and failing. As such it does not manage go get the forecast for your pos. Pull the latest, I added a new source of geo location data that should find you.

from airiana.

The fix for geolocate solved the crashing of the Airiana service. I have now a latlong.json with latlong location
{"lat":"58.34046","long":"8.59337"}
and Airiana read the data from the vtr500

The buttons for Fanspeed Low, Normal and High and Forced Ventilation do not work. When I push them the fan do not changed speed. Auto on/off works. I do not know if Winter/Summer mode works because the Airiana do not give any output i the terminal window.

The home assistant integration works, but I must change the port from port":8234 to port":8123 in the "ha-token" file. I get three sensor in Home Assistant. Is this correct?

from airiana.

How do you send the json file with mqtt publish to home assistant from the raspberry pc? My Home assistant pc have Eclipse Mosquitto broker already.

I think the commit did not help.

I am trying to setup mqtt publish to home assistant, but my air.out file is empty (no json data). I have restarted airiana, but the air.out do not get input data. Two days ago the air.out was filled with json data.

pi@airiana:~/Airiana $ cat ./RAM/air.out 
pi@airiana:~/Airiana $ 

from airiana.

The json print and the fanspeed set is working now. Great work. I am going to test airiana now and report if I find more problems. Thanks again.

from airiana.

I do not know if these info/warning/errors in /RAM/err are things you need to fix, but here they are. When I push the "[Winter/Summer Mode]" button nothing seems to happen. How can I verify the Winter mode is enabled?

from airiana.

Updated to 52e34ed and everything works fine. I get a error about "json-writer error []" when the airiana service start up, but forecast.json and air.out are updated with data so I think is only a startup error.

I have a question about forced ventilation. I tried to use the service "RESTful Command: force_vent" in HA to force more air when fire up the fireplace. How can I controll the time the fan is on and how can I change back to auto? Is it better to use the service "RESTful Command: vent_high" with a time delay and then use "RESTful Command: vent_low" for stopping the fan.

Has something changed with the temperature picture in the webpage? The picture has on the left side black bars which is not pretty.

from airiana.

Have you updated? The black bars looks like there are temp values in the thousands, the bars being temp levels stacked on top of each other, the graph looks strange in general. Pull latest and see if there is a change

from airiana.

there may also be an extra button available just for you. hope it works well to light a fire in the fireplace with minimal smoke going in.

to explain the forced vent, its actually just a timer, turns off auto for 120min and sets fanspeed lvl 3.
fire start mode sets a positive pressure ratio, this should push air up the chimney when starting, keeps positive pressure for 10minutes before returning to auto.

give it a try and lets evaluate.

from airiana.

I started with a fresh install like you adviced here: #22 (comment).
But the airiana service do not start up and the log says the user pi do not have permission to create data.log, forecast.txt, err. https://gist.github.com/overas/7c9b49e999d9ec7efe4618b2c77c6f4e.
I then replaced the user pi in /etc/systemd/system/airiana.service with root and the service start up. The files is also created.

I do not see any new button for fireplace in the webpage. Should this work as a rest_command also in HA?

After I did a fresh install of Airiana the temperature picture is now correct.

The problem with the temperature picture has come back. The picture has also gray horizontal stripes in the background.

from airiana.

I think the problem is with the data. I looks as you are getting data in at around a few hundred Celcius. Can you attach or look in the data file "data.log" for entries around this date use this converter on the timestamps to find where this happened. If you pull the latest I revised the scaling procesure of the graph to make it readable if this happens again.

from airiana.

Sorry for late reply. I attach the "data.log" file. I think it is easier if you look at it. The graph is normal now, but I hope you can find it out.

data.log

from airiana.

had a look thru of your data file, it seems that the systemair unit is reporting temperatures in excess of 4000C at a few points. The grey lines are the 1C step lines that get pushed together. I'm not sure why you are getting "hell-level" temperatures sometimes,

from airiana.

Thanks for your reply. Today in the nighttime I had the same insane temperatures for the inlet temperature. I am going to try the new fix you made today.

from airiana.

Now I think I have a problem with the humidity. It seems the calculated outside humidity is out of range. After a shower the fan do not go from low to high anymore.

data 22-04-2022.log

from airiana.

something is very strange with your sensor data, the indoor temperature seems to have flat lined at 0.0C, this causes the humidity calculations to err. however the shower mode should still kick in as this is only dependent on the humidity sensor and that data looks intact. Have you tried rebooting the whole systemair unit?

graph from your data,

from airiana.

added some fixes aswell, hopefull that this will take care of the flow offset printouts in the error log

from airiana.

Thanks again. I rebooted the VTR500 and the IAM and it seems this has helped. The graphs look correct now with outside temperature 8.9 degree and a humidity 30 % at 06:57.

data 23-04-2022.log

from airiana.

however the shower mode should still kick in as this is only dependent on the humidity sensor and that data looks intact

The "Shower detections" is not working. After a shower the fans do not go from Low to High. I can not remember which commit made the problem, but it has worked. The reboot of the IAM and the fan has not helped either.

The calculated outside humidity is way off in the picture. It seems the data is to high so the graph starts to go above 100 %.

I have also in the err log a few times:
`Write error, no tries left on register:1403 None

I have now restarted Airiana service so the data.log do not have much data. I am going to attach the data.log later

Here are the data.log after running ./backup.py and the err file. I get a lot of:

in the err file. Can this explain the missing relative humidity?
`

from airiana.

From the HA history graph it looks like the relative humidity is above 100 % two times.

from airiana.

Yes this happens when your unit starts to report zero values on extract temperature, very unclear why it shifts sometimes.

from airiana.

After a restart of the airiana service the values is back again to normal.

from airiana.

I am trying to do a fresh install of Airiana following your advice here: #22 (comment)

I know get an error with install.py

pi@airiana:~/Airiana $ sudo python3 install.py clean

AttributeError: module 'pwd' has no attribute 'pwuid'
pi@airiana:~/Airiana $

from airiana.

fix to pwuid is up,
just to explain some of your questions above, unable to ping means that the unit is not able to contact the internet and do a DNS lookup, "no internet connection".

The reason that the RH is above 100 is due to the fact that when it is receiving 0C as indoor temp, it calculates what the outside max possible RH level is expressed as a relation to the indoor temp. If the outdoor is higher than 0C this will result in a above 100% RH as the 0C would generate condensation if outside air were to move inside.

Is this something you can fix in Airiana? Or is it something wrong with my fan or IAM?
Today my wife and I have showered twice. Airiana do not sense the high moisture in the bathroom and the fan does not change to high to lower the humidity.

from airiana.

I think Airiana configured my VTR500 fan to have airflow "Low" and "Temperature" 24 degree now. I want to have airflow Normal. How can I configure Airiana to use Normal as default?
I have tried Fanspeed Normal but it change back to Low.

from airiana.

quite the challange, I'm reluctant to blame hardware, I have however been unable to find a reasonable cause within the airiana code to explain the Zero temp issue. While reading above, did it clear the issue both by resetting the VTR unit or restarting airiana. if both are valid it must be something within the comms layer but I have no possibility to test this.

The shower issue is happening due to the zero temp causing the exchanger setting to turn on and off repetedly, It will detect that it is cold inside(0.0C) and then see that it is already at set temp for the supply line which will turn off the exchanger, this will set a hold off timer for all sensing for 10 min. this hold off timer causes airiana to not activate the shower mode.

To get to normal vent lvl you will need to toggle system auto to off and press the norm fanspeed button. this will however turn off all automated features.
When all is working as intended Airiana will use the norm setting when it reaches a high differential of the humidity, It will change the low flow settings dynamically to get a steady state for current humidity load of the indoor climate. So default for airiana is low if all metrics match up while dynamically changing this level when needed.

from airiana.

Noted that since we are getting the proper RH values I may be able to work around the shower issue but it will take a little time to figure out the actual implications of changing the logic. It may impact other things.

from airiana.

Sorry for late reply. I have been testing Home Assistant modbus sensor integration for trying to find out why the unit starts to report zero values from the extract temperature. This do not happen as a sensor in HA.

But I had problems with IAM reporting in the HA log it was busy. I have tried changing the ethernet cabel and not using a switch and using av delay in the config, but it did not help. After a while with troubleshooting I found out from the systemair documentation https://shop.systemair.com/upload/assets/SAVE_MODBUS_VARIABLE_LIST_20190116__REV__29_.PDF, I must have in the config the signal type used.

From the HA modbus doc https://www.home-assistant.io/integrations/modbus/, the Unsigned integers use data_type: uint16 and Signed integers use data_type: int16.

  - name: "VTR500 Extract Air Temperature"
    unit_of_measurement: °C
    device_class: temperature
    slave: 1
    address: 12543
    scale: 0.1
    precision: 1
    data_type: uint16

I tried to find in the airiana-core.py if unsigned integers is specified for address: 12543, but my knowledge in Python is not so good. The pymodbustcp libary have this documentation about this https://pymodbustcp.readthedocs.io/en/latest/quickstart/index.html#utils-module-modbus-data-mangling

So here comes the question. Could it be that pymodbustcp is reading wrong from address: 12543 and give zero or something else which airiana thinks is temperature 0 degree? Look here: sourceperl/pyModbusTCP#22

from airiana.

It is something wrong with my IAM I think. I thought I had solved the SlaveBusy error, but it comes back again.

Do you use a IAM to communicate?

from airiana.

from airiana.

I have a lot of "TCP read error on adresse" displayed in the webpage. This I have seen before. But know it verifies the communication problem with the IAM and the vtr500 when its logged.

The vtr500 modbus communication setting I use is:
Slave address: 1
Baud rate: 115200
Parity: None
Stop bits: 1

I do not know what baud rate the IAM use. It should be the same as the vtr500. Maybe it is wrong baud rate which gives communication problems?

I found the fault. It is not a problem with IAM, Airiana server or pymodbustcp.
It was the Deco M9 Plus wireless router I use as a ethernet switch to connect IAM through the wlan router ethernet port --> Deco Internet router. When I connect the IAM direct to the RJ-45 port in the wall without the Deco I do not get TCP read errors at all.

Without Deco as a switch (IAM direct to the RJ-45), here is a summery of things I have tried,

• It is not wrong baudrate. I have tried with 2700, 19200 and 115200 and I do not get TCP read errors at all.
• When I use the my wlan and not cable connect through the Deco wlan router I do not get TCP read errors. So it is a problem with the Deco ethernet port (it has two).

I think you can revert some of the debug code. Thank for your support and feedback .

I have a feature request. My vtr500 has Eco mode which I use from 23:00 to 06:00 to lower the temperature 3 degrees to save energy. Could this be implented in Airiana?

from airiana.

I have one more feature request if possible. Airiana report the power W.

It has been nice if we could also have the unit of measurement in watt hours or kilowatt hours. I know I can use the Rieman sum integration to sum up to kWh, but if this is possible in Airiana it has been nice. https://www.home-assistant.io/integrations/integration/

from airiana.

I think the calculation of kwh is wrong. In HA the kwh is really small.

  - platform: mqtt
    name: "Electric power total"
    state_topic: "airiana"
    unit_of_measurement: "kWh"
    state_class: "total_increasing"
    device_class: "energy"
    value_template: "{{ value_json.electricPowerTotal }}"

kwh from air.out
"electricPowerTotal": 0.00033652760590360315}

I used a Fibaro powerplug to measure and calculate the kwh from 00:00 to 10:00. The kwh is more correct with the powerplug.

from airiana.

It is better to report the value as kWh instead of Wh and only have one decimal behind the comma.
