Here is the thing with channel configuration for Athom EM2 (2 channel).
It assumes that MQTT topic on the device is set to energy_meter.
Also, set your bridgeUID to your MQTT bridge.
I haven’t added a summary values (Energy Today, Energy Yesterday, Energy Total) as OpenHab has better ways to display and summarize these values.
Hopefully it will save you an hour to configure all channels.
