I’m having couple of Frient wall plugs which can report power and energy. It is ZigBee device and I’m using Zigbee2mqtt. They seem to report every now and then funny -11 000 W or so power values which make graphs look quite useless. How I could get rid of that? In which component and how I should remove these clearly out of bounds values? I would guess something can be done before writing the data to the recorder database.
