Unable to import component

[colseven]

Since yesterday there are problems with the recognition of c5 after restarting Home Assistant. Another restart also leads to the error, yesterday I was able to de-energize the RLT system, after which it was recognized by ha after another restart - unfortunately not anymore today. that's the mistake.

Interesting, I haven't encountered anything like this yet. It's possible that you ended up with an incompatible version of pymodbus. Can you check which version you're running?

[colseven]

Okay, how can I check the pymodbus version because - I couldn't find anything.

Problem since HA Version 2022.4 and only after a reboot.

The existence of the 'compat' module basically confirms that you're running pymodbus 3 rather than the expected pymodbus 2. Im not sure how this happened because pymodbus 3 doesn't even habe a stable release yet. Are you perhaps using another integration which depends on pymodbus?

[colseven]

Good question, actually nothing new. SolarEdge Modbus will probably use it, but I've had it for a long time. Currently I'm helping myself as follows. Make RLT stromloas and restart HA, then it always works - exactly until HA is restarted.

192.168.178.50 is the IP address to my komfovent

[siku2]

Is something else connecting to your unit using Modbus? Komfovent can only handle a single client at a time. Otherwise, it just looks like your unit is unreachable (wrong IP, firewall, etc.)

[colseven]

The error actually only came up after I connected my solaredge inverter via modbus, which of course has a different IP of its own. Something is wrong, there is no error message with the solaredge add on. what can i do to fix this, because 400000 errors in a few hours can't be healthy.

Mhm, my Komfovent IP is 192.168.178.50 ... why it will connect to 127.0.0.1 ?

Unless you specifically entered that IP, this integration can't possibly connect to ipv6 loopback and ipv4 loopback. Must have something to do with the solaredge integration.

[colseven]

Great, disable this in Solaredge, reboot and no Error. THX

[colseven]

Solved with: update_interval=timedelta(seconds=40), client = await Client.connect(host, port, connect_timeout=35.0)

no errors since yesterday
