I’ve had Hanchu ESS batteries and an inverter installed and they have some great features but HA integration isn’t one of them, unfortunately.
I know there are a couple of prototype interegtations that scrape the Hanchu web site but Hanchu provide a local Bluetooth interface too and I wonder of that would be a better way in - though I’ve no idea what’s involved. HA does recognise the Bluetooth devices at lease though it has no way to connect to them.
Are there Bluetooth diagnostic tools I could use to explore a little?
(I have zero HA development experience.)
