It is probably a known problem (without debug logsI cannot tell). There is a patch being tested which will be submitted soon.

Hey there @adamchengtkc, @vzahradnik, mind taking a look at this issue as its been labeled with an integration (modbus) you are listed as a codeowner for? Thanks! (message by CodeOwnersMention)

issuluca commented 3 years ago

I also have the same problem with an ABB inverter ... with the old modbus version never had problems, since I had to change it in the morning it is always unavailable

Modbus sensors against host experience momentary outtage, however never seems to reconnect without a reboot Haas 2021.7.2

0210717 - 15:45 Pymodbus: Modbus Error: [Input/Output] [Errno 104] Connection reset by peer restart required

20210718 - 01:30 Pymodbus: Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response received, expected at least 8 bytes (0 received) restart required

These errors may well have occurred prior to 2021.7.x, however i didnt experience permanent sensor unavailable response prior to moving from 2021.6.x to 2021.7.3.

Yes there may be the odd issue if network momentatarily unavailable for example, however modbus would recover, and not require a reboot of Haas to get sensors to reconnect & update.

I left sensor in unavailable state for 20 minutes & it didnt seem to attempt reconnect via modbus. Sensor from that point unavailable untill haas a reboot. Given there is no way i could easily find of restaring modbus module or integration so to speak, a reboot seemed to be my only option

https://github.com/home-assistant/core/pull/53020 solves that issue.

I'm seeing this as well. The only thing I see in the logs related is:

Logger: pymodbus.client.sync
Source: /usr/local/lib/python3.9/site-packages/pymodbus/client/sync.py:218
First occurred: 12:17:15 AM (3 occurrences)
Last logged: 12:17:21 AM

Connection to (192.168.6.13, 502) failed: timed out

I'm running Home Assistant 2021.7.3

I made all the required changes for Modbus for 2021.7

Also, while all of the devices for one endpoint go unavailable, I have other endpoints which are still working.

remyderuysscher commented 3 years ago

I still have issues after upgrading to 2021.7.3 with modbus RTU. Error are absent for a few hours after restart.

mawreegnau commented 3 years ago

The problem was not solved with the 2017.3 I have to reboot HA every morning to make modbus connect.

janiversen commented 3 years ago

The last log shows the device is not responding, so you need to look for the cause in the device or earlier in the debug logs.

mawreegnau commented 3 years ago

The device (a solar inverter) goes in sleep mode at sunset. Totally, even the tcp/ip. At sunrise the device wake-up and start tcp-ip comm. But HA seems not to notice, and only a reboot restores communication. It worked perfectly in 2021.6

janiversen commented 3 years ago

Set timeout sufficient high that should solve it.

janiversen commented 3 years ago

Test with 2021.8

janiversen commented 3 years ago

Closing issue as solved.
