Auxiliary Loads and Mains Charger Controller for my Smart Mobile Home
-
A simple node to enable/disable the 12V power supply to auxiliary non vital loads (e.g. water boiler) based on the service battery voltage. A relay is controlled by the presence of a charging source.
Additionally, in presence of other charge sources, the Mains Charger is disconnected from the Service Battery. The Mains Charger relay is enabled if there are no other charge sources and the camper is connected to the Shore Power.There are 2 additional analog voltage input.
I tend to create edge nodes, with full capability of serving the desired use cases, even if Gateway/Controller are down. In this case I can Arm/Disarm some automations from the controller using S_DOOR sensor types.
