Hi @daveo2k,
I also own a NIBE heatpump (although an older model, F730) and a SolarEdge inverter. I selected openHAB as the system of choice because for both systems there were bindings available.
Nibe’s MyUplink seems unsupported at the moment. See threads Nibe REST API - #74 by pacive or Nibe uplink binding - #242 by KlingsporC.
In the meantime I am using this binding for my heatpump (F730 model): Nibe Heatpump - Bindings | openHAB. But this needs hardware modification in the interface to the heatpump and setup the MODBUS feature in the heatpump settings.
For the SolarEdge inverter you can take the bindings mentioned above. Or you may communicate via ModBus TCP locally (has to be enabled on the inverter).
