I have mounted two relay units to control 2 1KW sections of our water heater. I had the one relay controlling from NodeRed but not the second. I changed a setting in node section of NodeRed and have been trying to make it all work without any luck since.
What settings are required in CodeRed to communicate with the Wifi MQTT relay in the WQTT out node especially the topic name?
In the Relay Settings I have:
Device ID emonRelay1
