My installation consists of solar panels, Pylontech batteries, a Multiplus II, and a Solar Charger MPPT 450/100. This set is controlled by a CERBO GX. I have installed Venus Large and Node-RED.
I already control a hot water tank from a CERBO GX relay programmed with Node-RED.
I would also like to program the primary relay of the Multiplus II via Node-RED. I can do this with the Relay Assistant but cannot find it with Node-RED. Do you have an idea?
