Help with setting up the Program on the D1mini about ha-watermeter HOT 43 CLOSED

I tried to follow the steps on your repository, but what do you mean with:

If you have wired the Wemos D1 Mini and CC1101 as shown in the picture, then you do not have to change anything.

I also created the secrets file

WatermeterID is usually the ID on the water meter.

WatermeterHost is only required if you use wmbusmeters i a pipe.

Tipp:
Set the meter_id to 0

and the log_level: "VERBOSE", than you can see the meterId (debug console).

from ha-watermeter.

Thank you for you reply.
That helped me and I was able to get the ID and finish the setup.
I found out that the watermeeter seems to send every 15 minutes a signal according to the manufacturer
https://www.diehl.com/metering/en/products-solutions/products-services/system-software/system-software-components/izar-rc-i-r4-at/#izar-rc-i-r4
at least I am not getting readings every 8 seconds...
Do you get threre a more precise reading?

sometimes the reading seems to fail - see below highlighted - as a result a "nan" is sent

and homeassistant gets an "unbekannt" status

Do you know why this is happening?

Furthermore I also corrected this two entries to make it compatible with the HA energy card configruation

unit_of_measurement: "m³" state_class: "measurement" geändert auf state_class: "total"

I think the problem is this error.

Which version of ESPHome do you use ?

you can try it w/o the script - id: post_device_state, delete or comment the call in line

      line 547:  id(post_device_state).execute();

unit_of_measurement: "m³" state_class: "measurement" geändert auf state_class: "total"

o.k but both will be correct.

Long-term Statistics
Home Assistant has support for storing sensors as long-term statistics if the entity has the right properties. To opt-in for statistics, the sensor must have state_class set to one of the valid state classes: measurement, total or total_increasing. For certain device classes, the unit of the statistics is normalized to for example make it possible to plot several sensors in a single graph.

I am using this version https://registry.hub.docker.com/r/esphome/esphome/ running on my Synology Docker Container.
[v2023.3.2]
I dont have a line 547 and also no content of this script.
I am using this pre-release https://github.com/zibous/ha-watermeter/releases/tag/1.0.1
in the yaml it says appversion: "1.1.1"

yes, both are indeed correct, but when set to "measurement" HA gave an error that the "last_reset" argument is missing, therefore I tried it with the "total" and HA didnt gave an error.

from ha-watermeter.

[v2023.3.2]
Ok, same Version here but on a NUC.

see: I dont have a line 547 and also no content of this script.

O.k the version https://github.com/zibous/ha-watermeter/releases/tag/1.0.1 do not have this, only the current.
But the error comes from ESPHOME and the version 1.0.1 does not use JSON. So I can't explain that.

HA gave an error that the "last_reset" argument is missing, therefore I tried it with the "total" and HA didnt gave an error.

I use Home Assistant 2023.4.4, Frontend 20230411.1 - latest. state_class: "measurement"is working.

from ha-watermeter.

I found the 1.1.5 on your github repository https://github.com/zibous/ha-watermeter/blob/f4bf78711a9e9b96fcbd940e071a1ddc8204c15e/esphome/wmbus-minid1.yaml

There you have the state_class: total_increasing defined instead of the "measurement" from the 1.0.1
I just seen that I use Home Assistant 2023.3.0 Frontend 20230301.0 - latest - maybe they changed there as well, but I wanted to finish this integration before installing the April release.

Is this the most actual version? can I use that as well - or do I have there other pre-requirements?

--> means, that the id(waterdisplay).state has no value.

but you can try to disable the template.

- platform: template
    id: watermeterdata
    update_interval: ${update_interval}

Is this the most actual version? can I use that as well - or do I have there other pre-requirements?

Yes but has only more features.

@compumark

Sorry..

The new version should work.

and https://github.com/zibous/ha-watermeter/blob/master/esphome/README.md

Hi, no problem :)
This one is working now. I added under the section # reset all global vars the "id(current_value) = 0.00;" as this was missing, what I noticed. Dont sure if needed, but yesterday when playing around it was helpful.

Do you really get every 8 seconds a signal from the water meter?
Mine are coming in very strange Intervalls . Is the programm always listening to the frequency or is it polling actively and by luck it captures a transmission?

It could also be because the Wemos D1 Mini and CC1101 is too far from the water meter.
The signal on the CC1101 is not exactly high and fluctuates very strongly.
I would try to bring the D1MINI closer to the water meter.

Interesting. My device is roughly 3m away from the meter. But seeing your dB counts shows that yours are worse than mine with the -61db in comparison to mine with -40 range. I will move it nearby to the meter with a longer power cable and will monitor this.
But maybe it was really configured from the water department of our city? But if they are doing the yearly readout they are moving on foot or car in the street. And the meter is in the cellar with Dichtbeton. So they are able to catch the signal.

Then you have to have a source of interference ...
My Watermeter is 10m away and in another room.

I will move it nearby to the meter with a longer power cable...

Ohh it could also be the power supply, I had such an effect on another device.

But maybe it was really configured from the water department of our city?

No i think not, the only importent part is the telegramm and this is o.k

And the meter is in the cellar with Dichtbeton.
Yes same here...

from ha-watermeter.

Tried now 3 different power supplies and 3 different usb cables, all the same effect. No readings since 20 minutes.
What I also noticed during building, that the card was not fine cut and the 3 holes where to wire the antenna in the middle are only existing as half. So I did solder another cable in-between the card and the antenna to fit the antenna. I already contacted Amazon and I will get tomorrow a new one. Maybe this longer antenna has also negative impact on the setup.

But that would explain a few things. If you set the log level to VERBOSE, you would have to see more.

ok. i use 2 of theese on: https://amzn.eu/d/i5YwBkR
No Problems.

from ha-watermeter.

Update from my side. I received the new antenna board, same crappy cut as the old one.

I wired it in the evening, but far away from the 8seconds reading.

here the whole day:

and since the board change:

I found the same boards on ebay: https://www.ebay.at/itm/233689592394?var=533375579177
maybe I risk to order 2 of them, maybe there are another batch and do not have the wrong cut

from ha-watermeter.

How close is the CC1101 to the D1MINI ?

It is strange that it works almost all the time and only sometimes fails.

If you use the neighbor's water meter (he has a much worse signal) it is the same ?

from ha-watermeter.

The wires between the 2 boards are around 8cm length.
I can try to shorten them as well in the evening.
I need to check the log files for the neighbors meter intervals, will do that as well in the evening.

@compumark

I can now see the error with me too, but only with the second D1MINI.

• Both are wired indent and have the same hardware and
  from the same supplier and same order.

• One works fine and the other always boots with a JSON error.

As it looks it could also be due to the D1Mini.
In the variant with an ESP32, the version works perfectly.

from ha-watermeter.

Hi @zibous ,
thanks for the follow up - I have not received the new antenna boards yet, but I will try in the next days the setup in a different house and see if i get there more intervals.

The error you mentioned now is the JSON error which appears in the debug log sometimes or the issue that you are not getting the readings every 8s?

Whats the ESP32 variant? is this another board?

from ha-watermeter.

see: https://github.com/zibous/ha-watermeter/tree/master/esphome

Whenever the D1MINI reboots, the receive loop is restarted.
You should see the number of boots in the "Bootcounter".
With Reset Boot Counter YOU can reset it.

Hi,

I found and bought an adapter board for the CC1101. Cost $2.85 (no shipping).
This certainly makes it easier to connect the CC1101.

I'm curious how long the delivery will take.
see: https://oshpark.com/shared_projects/dVZXCMXP

from ha-watermeter.

Soldering that CC1101 module is pain. That's why I have my own board for D1 mini.

from ha-watermeter.

@SzczepanLeon

Confirm, I already destroyed one, you can only solder once...

? That's why I have my own board for D1 mini.

Upload has not work, can't see your board.

Do you sell those too?

from ha-watermeter.

Yes, but I'm waiting for PCBs. Should be around 3 days. Blue from picture is my v1, now will be v2 (black and with small diferences), next v3 will be with pads for SMA antenna connector (and of course in another color ;) )

from ha-watermeter.

@SzczepanLeon

Perfect looks really good.

How can i order 2 of them and what would that cost me?

from ha-watermeter.

I will know details around Tuesday.

Du use the default pins ?

o.k

from ha-watermeter.

No, all my private ESPs are ESP32 and I use different pins.
In next release they will be updated to D1 mini SPI.

from ha-watermeter.

@zibous I received my 2 new C1101 cards, but they are even worse cut :-(
But I will try anyway to solder them.

When trying to compile the working script again I now receive errors:
Anyone an idea why?
The yaml is the same I compiled weeks ago without an error, but also this is not working to compile anymore.

Seems that something was changed on the esphome components
https://github.com/SzczepanLeon/esphome-components

But I have current no clue what and how to use an older library of the esphome components, that worked...
any help is appreciated. :-)

from ha-watermeter.

yes has changed:

see: esphome/wm-d1mini.yaml

I received my 2 new C1101 cards, but they are even worse cut :-(

I think they are ok, because they are prepared for mounting on an adapter board.

Leon has has a nice one: https://github.com/SzczepanLeon/esphome-components/raw/main/docs/pcb_v2.png

For me, however, the D1Mini are critical because they have little memory. ESP32 works better.

Simple Testversion: https://github.com/zibous/ha-watermeter/blob/master/esphome/wm-d1mini-simple.yaml

from ha-watermeter.

Thanks @SzczepanLeon and @zibous - that worked for me.

I am now testing the 2.07 version - nice improvements and very well documented - congrats to that.
When I am flashing my productive watermeter with a connection to HA, I assume all my values are gone.
I assume changing the global variables section to my last known values like "yesterday_value, week, month and year" should be the way to go to continue with the measurement. Am I correct?

• No, the Homeassistant history data for a sensor is only based on the name by the esphome configuration:
• global variables are only used internal by ESPHOME

Example: name: "Wasseruhr Anzeige"---> Homeassistant sensor.wasseruhr_anzeige

total_water_m3:
      id: "waterdisplay"
      name: "Wasseruhr Anzeige"
      unit_of_measurement: "m³"
      state_class: total_increasing
      device_class: "water"

Yes this one has ROM: 448 KB - SRAM: 520 KB, D1 mini ESP8266 80MHz only 80KB RAM.

But is then there an option to flash and continue with the same data?
eg: Thats my productive D1Mini

and this now my testing device with the 2.07 version - which started counting by 0

from ha-watermeter.

Yes you can try with homeassistant service call : esphome.water_meter_set_water_val:

service: esphome.water_meter_set_water_val
data:
 water_val_hour: 83.98
 water_val_day: 414.00
 water_val_yesterday: 181.00
 water_val_week: 4479.98
 water_val_year: 18701.99
 water_val_lastmonth: 448.14

This will update the global vars.

in my case:
