"Invalid handler specified"

[danielecosta7]

Errore durante l'installazione dell'integrazione (dopo averla scaricata e installata da HACS, ovviamente post reboot) Impossibile caricare il flusso di configurazione: {"message":"Invalid handler specified"

Can you please add the logs.

Same (except for the language) error message here. This is what's in the logs when I try to install the integration:

… which actually seems to have been fixed three weeks ago … :thinking: just not been released so far.

So, sorry for the noise, this can be closed as far as I am concerned. Thank you!

[marcolivierarsenault]

Yeah simply download latest version of the code 'main' until I ship a new release.

[danielecosta7]

Yeah, same problem. I download the "main" version and now it's working. Thanks!
