I have the openEVSE connected to the HEMS now via MQTT (thanks for the smooth remote setup!).
As well as the powershaper events, I was hoping to be able to use this to manually toggle charging myself, or based on automations.
I have managed to create basic on/off automations, but really would also like control over the current, IE lower the current when the EVSE gets turned on during the day, so I can balance against solar output.
I know the functionality exists, as per: https://www.youtube.com/watch?v=tjCmPpNl-sA&t=1s&ab_channel=GlynHudson
however the available MQTT options only show the charge current as a sensor. Any Ideas?
