Auxiliary Loads and Mains Charger Controller for my Smart Mobile Home

fsgraz last edited by

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.

We are of like minds, Don't like the cloud based controls (that's another discussion). In my case I have a Bryant/Connex system, heat pump, variable speed fan and 4 zones. There's a lot going on: the 4 zones creates 16 profiles. The fan speed for a profile will depend on the indoor and outdoor temperature. The thermal fluid pump also has to be controlled. A profile will have an optimal air pressure, so there's a sensor there. The controller works just fine not being connected to the cloud. But I want to set the parameters remotely, Bryant/Connex can do this. I also wnat the status of the various actuators and sensors to show up in Home Assistant. The signals sent over the RS422 are proprietary. My plan was to reverse-engineer the signals. After doing this I'll have to experiment to get the right mix of air pressue, fan speed and thermal fluid flow for each profile. I'd like to do the same for my AO Smith heat pump water heater. I'd like to follow your progress. OSD

The output of the display could also be sent over serial, but the whole idea is you can walk around with the doctor and improve your results as you go.
