Integration Modbus - Error with Core Version > 2024.3.3 #119505

Closed Wolfgang-03 closed 4 months ago

Wolfgang-03 commented 5 months ago

The problem

I am using a USB2Serial (RS485) adapter to get data from an energy meter, what has worked well for months.

After Updating from 2024.3.3 to 2024.4.3, I get the following error:

Pymodbus: EM_Heizung: Error: device: 0 address: 1056 -> Modbus Error: [Input/Output] ERROR: No response received after 3 retries

If I go back to version 2024.3.3 everything works fine. I have tried several version between, up to 2024.6.2, the problem still remains the same. Only line number chages from 318 (2024.4.3) to 331 (2024.6.2)

That is your device, not responding.

Please add a debug log as pr modbus integration documentation.

How can it be my device that is not responding when it works perfectly with 2024.3.3?

janiversen commented 5 months ago

Because the software is different (see release notes), and the demanded python version is different.

I need to see a debug log, to determine if there is a bug in the modbus integration

Wolfgang-03 commented 5 months ago

janiversen commented 5 months ago

As I suspected:

2024-06-12 21:52:06.833 DEBUG (MainThread) [pymodbus.logging] Connection lost comm due to Server not responding

your device stops responding or something in between stops the traffic.

But the communication gets back to normal, so what is the real problem?

janiversen commented 5 months ago

And you have an error in your template:

{% endif %}) renders=2> Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/helpers/template.py", line 2229, in forgiving_float return float(value) ^^^^^^^^^^^^ ValueError: could not convert string to float: 'unknown'

Wolfgang-03 commented 5 months ago

And you have an error in your template:

{% endif %}) renders=2> Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/helpers/template.py", line 2229, in forgiving_float return float(value) ^^^^^^^^^^^^ ValueError: could not convert string to float: 'unknown'

The problem is, that the entity did not recive a valid value from modbus integration and so the value of the entity is set to "unknown". And "unknown" could not be converted to a float. I can of course rewrite the template and intercept the dropouts, but the dropouts are so large and so long that this is an unsatisfactory solution. And until version 2024.3.3, it always worked properly, with out dropouts.

grafik

your device stops responding or something in between stops the traffic.

I can't believe that there is a technical problem and the device stops responding. Why should the device do this, just because the querying software has been changed? There is also nothing in between, just one cable and and one electricity meter, no other devices on the same bus.

janiversen commented 5 months ago

No it actually worked wrong, because the dropouts was not reported, now all drop outs are reported (and due to the speed more are detected).

you might not believe it, but the modbus integration do not receive any data even after 3 retries, and I have not seen any logs that indicate a problem within the integration.

And there are a lot of things in between...the python interpreter, pyserial, hass, core which all have changed too, and of course your usb adapter which python might use differently.

Wolfgang-03 commented 5 months ago

But it doesn't stop at dropouts. In the end, I no longer get any data at all with 2024.6.2.

grafik

I don't know what the problem is, but if I go back to 2024.3.3, I get data again. So I went back to 2024.3.3 and then created a debug log, maybe that will help narrow down the problem?

home-assistant-debug_2024_3_3.log

There is always only 15-20 ms between "WAITING FOR REPLY" and "PROCESSING REPLY".

And all entities are available.

grafik

For 2024.6.2, all are set to "unavailable".

Wolfgang-03 commented 5 months ago

I replaced the USB2Serial (RS485) adapter to a complete new one. This one registers himself on /dev/ttyACM0.

grafik

Unfortunately with the same result. Runs under 2024.3.3, does not run under 2024.6.2

No unexpected dropout with 2024.3.3 grafik

After startup with 2024.6.2 I receive some data from modbus. grafik

Severall minutes later, more and more entities change to unavailable. grafik

I would assume that it has something to do with these two entries in the log:

I have made new debug-logs for you, first one is on 2024.3.3, second on 2024.6.2 home-assistant_debug_2024_3_3_newUSB.log home-assistant-debug_2024_6_2_newUSB.log

Please take a look at line 2253, 2255, 4345, 4347, 6474, 6476 in the second one.

Thanks!

What I can see is that in line 2262, 4364 .... the modbus integration start delivering data again.

Wolfgang-03 commented 5 months ago

I have noticed that a modbus/tcp integration is also active in my productive configuration, which runs smoothly, also under 2024.6.2. However, this modbus/tcp integration also writes data to the debug log file and makes things confusing.

To avoid mixing up things and to be sure that there went nothing wrong with my productive system, I have set up a new Raspi4 with a newly installed HA-OS, on which nothing else is running except the modus/serial integration.

This is what the yaml entry looks like, 1 sensor/entity, nothing else: 

modbus:
  - name: EM_Heizung
    type: serial
    port: /dev/ttyACM0
    baudrate: 115200
    bytesize: 8
    method: rtu
    parity: N
    stopbits: 1
    delay: 0
    message_wait_milliseconds: 60
    timeout: 50
    sensors:
      - name: EM Total Power
        unique_id: em_total_power
        unit_of_measurement: W
        address: 0x0420
        data_type: uint32
        scan_interval: 10

When I use Core 2024.3.3 here, it runs for several hours without any problems and I don't get any dropouts. I can also see request every 10 seconds as requested.

Debug_2024_3_3.log

After upgrading to Core 2024.6.2 at 20:45 (see logs), I only receive 2 values at 21:08:01 and 21:11:21.

Debug_2024_6_2.log

But I can't see in the log file where the problem lies.

Furthermore in the log file are only request every 50 seconds, not as requested every 10 seconds!?

I would assume that the main problem is that a response comes from the device (energy meter), but it is interpreted as an "Unrequested message", for whatever reason.

Can you please take another look at this? I cannot believe that it is due to the hardware or other components in my case, as I have really changed absolutely nothing (between 2024.3.3 and 2024.6.2) and the error also occurs with a completely new system. The only thing I can think of is that the energy meter is not supplying data 100% correctly, which obviously didn't matter until version 2024.3.3. But I am sure that the energy meter is still delivering data. I have also tested this in the meantime with a completely different system (Windows) and there I was also able to read all the data form the energy meter and did not get any errors.

janiversen commented 5 months ago

The "Unrequested message: ReadHoldingRegistersResponse (2)" is a bug, that have just been solved in the underlying library, this will cause responses to be dropped.

Once there is a new version of pymodbus, the modbus integration will be updated.

Feel free to try the dev version of pymodbus.

Wolfgang-03 commented 5 months ago

I can do that, but I am not familiar with how to test a development version of an integration.

Can you give me a quick hint on how to do this. Thank you very much!

janiversen commented 5 months ago

That depends a lot on your installation, there are no general hints. But Ha have documentation how to test/develop

amos41 commented 4 months ago

I have the same problem with ORNO counters Last version with those working until 2024.3.3

janiversen commented 4 months ago

Mam ten sam problem z licznikami ORNO

Ostatnia wersja z jaką działają to 2024.3.3

This is an english forum.

Wolfgang-03 commented 4 months ago

Once there is a new version of pymodbus, the modbus integration will be updated.

Which version of HA does the new version of pymodbus come with?

janiversen commented 4 months ago

Who knows, I at least do not know... release notes will tell.

amos41 commented 4 months ago

I solved the problem by changing the device address from slave 0 to slave 1 in the device configuration

janiversen commented 4 months ago

Slave 0 is broadcast and should never be used in production.
