Thanks for report.

Did this worked for You in previous Home Assistant version ? Which Ecovent Fan do You have. Is it v2.0 ?

Because battery_voltage should be in the form "3200 mV" but in Your case it seems that it is just number. This indicate, that it could be v1 fan.

[evaliukonis]

My Ecovent is V2. I bought it only yesterday and tried to add it to HA. It looks like some changes in Python and does not work with the latest version of the HA.

[gody01]

I just upgraded to 2023.6.2 and it's working here.

Is Fan in "Master" mode ? For integration to work, all fanse has to be in master mode.

[evaliukonis]

Yes, it is the master mode. I try but not possible add a slave to the HA

[evaliukonis]

I found my problem. I set up the device id. I should leave the default value DEFAULT_DEVICEID. Possible decrease update interval? Now it looks like 30 seconds.
