How is it possible that Energy reports 65kWh power consumed in a day by a <10W light switched on twice for a few minutes?

(TBH anything entitled ‘megathread’ generally makes me think of something more valuable to do with with my time!).

This was not an invitation to read through the entire topic, but a hint that the same or similar problems have already been reported and discussed in the megathread.

@K_S

so it would be my guess that the Athom software is trying to calculate the power consumed from those, not the Fibaro relay sending a total consumption figure

I don’t think so. In Developer Tools → Z-Wave → Log you can check which data is sent from your Fibaro Double Switch 2 to Homey.

@RogerSt

I guess that a reset of the device itself may then be an option. So reset/re-add…
