There's an issue in the underlying library that causes occasional glitches when fetching data (that's the Did not receive expected response type you're seeing in the logs. Sometimes this can happen on the very first try, in which case HA will report this error. This is expected to be sorted in the near future, but in the mean time, could you try to connect a few more times and see if you can get past this stage of the process?

[j1mco]

Tried a few more times. Logs maybe more legible:

I'm getting the same issue, I cannot connect. I've tried dozens of times. I also have GivTCP running on the network, and that is working (mostly) fine, so the inverter is online and available.

There's definitley some improvements pending in the underlying givenergy_modbus library, however I'd expect it to work most of the time, with just occasional errors.

Something I noticed today was that it's far more reliable in my Python 3.10 development environment. Having just upgraded my HA install to 2022.7, which introduces 3.10 for the first time, it now seems more stable on there.

Anyone want to try upgrading and see if that improves things?

[lxalln]

I'm running 2022.7, it's still not working:

Just to add here, I find a connection will fail if there is something else polling the device (givtcp for example)

[rjenx]

Sorry my repo is private so you wont see the error. I saw this in my logs yesterday, I have not seen the error since and my HA is showing up to date data today. I will monitor if this occurs again and under what circumstances.

Closing for now as I don't think there's anything that could be changed in this project to reduce connectivity issues.
