I have random reboots of the ESP32, several times a day.
New to the setup is the shunt, but also influx and mqtt.
My guess is it is related to influx

Attached is a stacktrace

Hi Stuart,
I finally got the serial outut when my esp32 controller reboots:
I pasted a bit before and an bit after the reboot so you have an idea what it looks like "normally", hope this helps

Rebooting...

Hello from Russia! I ordered circuit boards to repeat the project. I can translate the web interface and instructions into Russian, but I don’t see where the language data is stored. Sorry for my English if there are any errors.

Best Regards

Cannot get the wifi to connect after updating to newest version of code for esp32
platformio-device-monitor-210327-213744.log

Is TCA9534A necessary for the operation of Relays, SSRs. As the part is no longer available at LCSC.Com

When the controller is running for 8 to 9 hours without being touched the ESP reboots upon touch of the screen.
If there is a way to write logging to SD card I'm happy to try and log this behavior.

Did not notice this behavior in prev. release now running 2021-04-07T08:44:43.615Z

Somehow i don't get any MQTT messages from my 8th cell.
Version: 6c3d59e
Compiled: 2021-06-16T12:09:39.012Z

When error
"The controller is having difficulty communicating with the cell monitoring modules."

the BMS error should have triggered. The screenshot was from a test torture test and the voltages very low.

Hi,

Flashed ESP32 with nodemcu-pyflasher and all was ok no issues. Then used putty and connected via serial to try and connect o wifi but getting this response.

Any idea why I am getting these errors.

The esp32 i am using are the recommeneded ones.

Hi @stuartpittaway ,
We discussed Victron support on the Forum. There is a big customer base of Victron users out there and i think Victron support would make this project shine even more so i asked the the question on the Victron Forum how we could get started. You may want to participate especially if i am saying something wrong.

https://community.victronenergy.com/questions/93436/what-kind-of-protocol-do-you-recommend-to-implemen.html

/donnib aka Peter on Victron forum

I am trying to figure out a few values from the rs485 data stream, but cannot always use the serial as Im sometimes too far from the boat. Is there any way to output debug values over network?

I have tried https://github.com/MalteJ/embedded-esp32-component-udp_logging which resulted in a hang on boot, which I could not debug, as I did not have access to serial. It was probably just a bad init on my part.

I have also written some rudamentary functions to just concatenate text serve it as a webpage, but that corrupted the stack. My fault as well :)

I've just upgraded to the latest automatic version and I've noticed that all the settings have been lost, including wifi connection, shunt config and rules. I'm not using the onboard sd slot nor the display one.

Should the settings had survived if a SD card was used? The screen SD port can also be used? (the onboard port requires disassembly of the screen and the whole bundle if it is inside a box.

Latest ESP32 Firmware [Release-2021-06-16-12-11] has the following error

All 4 relays (Solid State and normal) on NEW ESP32 Controller not working / switching on.

Reflashed with this version and it works

Rebooting...

Pulse relay appears to hang or not reset correctly when changing the rules

Looks like static/esd on the inputs cause multiple interrupts to trigger causing reboots of the controller.

Inputs need to be grounded/held high - in software, change them to outputs for now.

We could include something like https://github.com/rubenv/pofile
That way we could use real polyglot tools like PoEdit to generate multilanguage interfaces. Let me know if you support this vision and i'll make a pull request.

Hi Stuart,
I downloaded and am currently testing the latest firmware (september 2021).
All spontaneaus rboots are gone!, thanks.
two issues I did find; the uptime counter is not correct;
When the 24hour mark had beenreached, the "day"count is the same as the "hour count", eg when it shoudl display 2days13 hours 5minutes, it shows: 13days13hours5minutes.

The other issues I found is;
when enabling logging via influxdb, but the influxdb server is not available (controllersnot able to write to influxdb server), then the controller reboots. (I tested when putting in wrong credentials, and also temporarily shutting down the influxdb server)

But despite these thing, I am very happy with the new firmware!

State of charge
For a State of Charge to work, Shunt needs to know the battery capacity.
Add a "Battery capacity" field in shunt settings.
Display SoC in main window (with one decimal).

"Consumed Ah" would be a nice feature.
When Battery is full, manually reset the SoC is 100% or otherwise set to "now battery is full", Consumed Ah is 0Ah
While discharing, Consumed Ah decresses, it counts down.
When charging, it counts up.
When it hits Consumed Ah 0Ah it stops counting. It will never raise above 0Ah.

Syncronize SoC
There should be a way to manually set SoC. If you know batteries are full, you manually syncronize SoC to 100%.
This resets "Consumed Ah" to 0Ah
Likewize, if you know SoC is 50%, "Consumed Ah" is set to half of "Battery capacity" times minus 1

Automatic SoC syncronize
Introduce a "Battery full voltage".
When shunt voltage reaches this value and stays above this value för "Charge detection time" (3 minutes) and current is less than "Tail current" (1%) (1% of "Battery capacity" eg. 560Ah battery when hits 56V for three minutes and it charges with less than 560*0.01 = 5.6A during this time = battery is full. "Consumed Ah" is reset to 0Ah

Unnecessary values
The other values "Ah In" and "Ah out", contributes with no usefull data (circled green).

Personally I don't think they belong in a overview window, more like a "extended data section"
Since they never resed, they are more a "Total Ah in/out" counter.

I need to persist a few values over resets, and for later calculations. What functions or strategies are the best for these scenarios?

Should ideally be persisted every update (ca 5 sec). Needs to be restored on reset

• currentMonitor.milliamphour_in
• currentMonitor.milliamphour_out
• current SOC for each cell

On change

• capacity of each cell

For visualisations (best to use SD card i assume):

• Current, power, shunt voltage etc.

When discharging energy is leaving the batteriy, so one would naturaly expect current to be negative when discharging and positive (no sign) when charging.

When I did a firmware update, all settings, battery levels, relay settings, shunt settings where erased. Also influx and mqtt settings where erased.
I selected "Wipe Eeprom = No"

The wifi setting was not erased. I did press save wifi and save configuration before the firmware update

This line in the buildscript_versioning.py causes local code build to halt

env.Append(git_sha_short=git_sha[32:])

Error messages:

Note that the errant line only exists if the code is downloaded as a zip. Downloading the repository via Git:clone from within VSCode gives a different buildscript_versioning.py without this line.

When rebooting diyBMS controller, the CANbus checkbox becomes unselected. CANbus communication is stopped

Is it possible to let the monitor2.json output also go through the serial connection?
Maybe with a checkbox enable/disable in the GUI.

Then it will be (for example) possible to read this from a device directly connected, not needing WLAN/CANBUS/RS485 .....

Now the output is only

Hi
Just wondering if State of Charge Rule could be added now that we have that info available?
Thanks
Jason

Please add CAN support for the CAN port.

the request was also made here: https://community.openenergymonitor.org/t/diybms-v4/11292/3697
(with PDF to download)
The same information I have about the CAN usage for my inverters is inserted as jpg, as PDF can't be shared here :-)

• CAN 2.0B
• CAN Baud Rate：250kbps
• 11-bit identifiers
• Little endian

Probably worth removing the wifi reset and leave at serial/usb console only as means to restore lost wifi settings.

If i activate both integrations, the controller reboots periodically loosing min/max and all historical values.
Mqtt alone works flawlessly. I haven't tried influx alone.
It seems to me like a memory leak.

If you have changed the default language in your browser other than English, in this case Spanish, the relays do not act.

We also find that if the screen resolution is small (ex: 1080x720) the relays do not always act.

Gracias.
Slds.

As title

As reported in the forum https://community.openenergymonitor.org/t/84-diybms-modules-not-working-as-expected/19261

84 modules in system, but last 4 not be read correctly after the first read.

I tried to use the condition currentMonitor.timestamp == 0 to check if the modbus parsing was in its first iteration. Unfortunately this always holds true as esp_timer_get_time() seems to always return 0.

There are a lot of us out there that don't want to/ can't upgrade to V2 of influxdb.

It would be really nice if we had the option of staying with the 1.x implementation.

Downloading any logged files larger than ~100k results in a hang and reboot of controller.
Small files (readme.txt) downloads correctly.

Rebooting...

An OOS error is generated when the packet counter rolls over (16 bit)

Amp hour in and out info boxes are missing unit (Ah). See image.

Using a TFT that does not have touch capability results in the TOUCH event being fired constantly. It would be good to have an option to disable this behavior. Or optionally ignore pressure=4095 to drop the event.

Hello stuart,
Is it possible to add fields in integration to submit a TLS certificate to be used in MQTT data transfer to a cloud broker?
Thanks in advance.

Hi
I am trying run this without a wifi network available. Can I set this to run as AP Mode and run the normal pages? The code seems to support it but I cannot seem to find a setting anywhere to allow it. It asks to select a wifi network and I cannot skip it?
Thanks for any help.
Jason

It would be interesting to have an intermediate option between the 200A and 500A Shunts.
That is why I suggest that the selection of a 300A sunt be considered, which would be an intermediate point

Screen touches makes the controller reboot. You only have to slide the finger around.
I'm on version 4.3, but i suppose it will happen on master.

The SoC is reported as 100%, but it is actually something else

Today I installed a diyBMS (esp32) setup in my boat. One controller and 8 battery modules. I already have two Juntek VAT-1050 shunts for measuring currents installed (one on all charge connections and one on all consumption connections). These shunts output their data on RS485 (using a USB connector!) and wireless using an nRF24* clone.

These units are rather cheap (~$30) and are available from all the standard Chinese resellers.

They have some "rules" functionality such as over-current and under-voltage which can trigger a relay. The protocol is largely known.

I was thinking about integrating these shunts in a similar way to the way the diyBMS-shunt is handled. Given that it is a rs485-protocol I was thinking I should re-use much of the code you have written for the diyBMS-shunt. Do you have any pointers?

Since HomeAssistant is getting a defacto standard, it would be nice to create a MQTT compatibility mode with HomeAssistant.

In relation to this https://community.openenergymonitor.org/t/module-voltage-bounce-sample-averaging/18469

Just wondering if it is easy to add SOC as a % to display of controller from current monitor. I know you are not aiming for much info on the display but this is a pretty basic one.
