Had a backup generator installed this year. Has wifi capabilities but didn’t want to commit to the monitoring/cloud fee. Generator also sits on a side of the house we rarely pass by to see the status LED on the unit.
Using a wifi2ir global cache (ITach) to watch voltage to the gas solenoid, yellow, and red LED status monitors for hardware.
Nice job. GC stuff is so expensive though (I have two Flex IP2IR units). I don’t suppose you want to hear that you could have done it at about a tenth of the cost with ESPHome
Take a look at this work I did last year with my generac generator Monitor your Generac generator with Home Assistant If you look at the genmon page referenced, you should be able to use this approach along with or instead of the wifi thing.
