hi @NibblyPig
I have been able to get all the data from Solis using Modbus through HA as below as part of our development of a home energy management unit. Happy to share the HA configs with anyone.
Works well, is rock solid and I can send the data to EmonCMS as well for aggregation and API access.
The part marked in red is me now trying to get full control over the inverter for community power/VPP applications. E.g. set the charge and discharge rate and times. The manufacture says its possible, I am going to next try Node-Red to see if having more control over the function code helps.
If anyone on this forum has experience with Modbus and can help me get full control over inverter, let me know.
