Hi 

Does anyone know how to get a alert or switch the plug off when the device power consumption drops

This is what i would like to use it for....

I have a chiller on my ice bath with a pump and compressor, the pump runs the whole time whilst it is switched on (uses 34-37w)  but the chiller compressor only comes on when the water temperature rises too high, when the chiller comes on power consumption goes upto around 270w then drops back down to 34w when its finished chilling and the pump is the only thing still on using the 34w

Id like a notification or to be able to switch plug off when the device has stopped using 270w and has dropped back down to 34w 

Is this possible 

Ive read people doing it for washing machines, its the same thing really 

I dont have 'power consumption' option in my automation trigger settings and from reading stuff on internet it seems some people do have that setting

Its the 4 way plug P304M 

Any help much appreciated
