We have an old 12v Renogy 2000 watt pure sine wave inverter with the original LCD remote control module plugged into it. I’m wondering if anyone might be aware of a way to tap into the data stream?
I do not believe that the newer Bluetooth modules will work with this older inverter charger.
This older system is going to be moved to a garage area and updated as it fails. I’d like to find a way to monitor it via my existing HA set-up, if possible.
