I am experimenting with medium scale Solar Power systems. Presently I am using openHab but in the next install I will be using hass because it look like it will be easier to DIY systems with. At he moment I am just switching lights on and off but I am wanting to monitor the Solar System as well as other environmental variables. Im using epEver Charge controller and Inverter, both of which use modbus. http://marksfieldnotes.blogspot.com/
