No, the Sunny Home Manager knows about what kind of load it is. For exemple if I define the load as a heater, then I’ve to enter the power rate, the minimum working time when it switches on, then the minimum time between a off and the next on. For the appliances, the Sunny HM switches them on (well not exactly, it sends a “switch on” command to the appliance through EE-BUS as I could do it with the Homeconnect app) and the appliance informs the Sunny HM when it’s finished. My appliances are always on so they can be remote controlled any time.
