Good morning,
I have a shelly em connected to a contactor then to a Bosch induction cooker.
If I turn off the contactor the consumption is 0 W.
If I turn on the contactor, with the induction cooker on, the consumption varies from 400 to 2000 W.
If I turn on the contactor, with the induction cooker in standby, the consumption is -11W.
Why do I have negative consumption?
Could it be the fault of the contactor coil?
How can I force a consumption correction?
Thanks everyone for the answers.
