Unable to connect to inverter - Failed to validate inverter configuration #60

Closed jon-riches closed 1 year ago

Hi

Thanks for your work on this.

I have a recently installed Gen 3 Inverter, can successfully connect via Britkat's giv-tcp, tried this as an alternative that may suit my needs better, however cannot get it to connect. I saw the other similar issue, but note that it's a different serial, and the other integration works ok for me.

HA Version 2023.7.2 HACS 1.32.1 GivEnergy Local v 1.8.1

Kind regards

Jonathan

The root cause is a common one that I've now recorded in #61. giv-tcp has taken this approach, which is why it's working for you. I'll close this one and point any more related issues to #61.
