I want to run this past some of the smart guys :
About 18 month back I put on a Sonoff POW to monitor my deep freeze and for all that time, was perfect.
I noticed at the start of April that my power consumption to the freezer was reducing was reducing from the standard 1.9kWh per day gradually - but I put this down to the freezer working less, due to ambient temperature reducing. However I came back on the 17th April and everything was defrosted (had to throw away) - it used half the power of normal. So I put this down to freezer issue and bought a new freezer, as well as made plans to get rid of this one.
But last night I decided to
remove the Sonoff - and freezer worked like normal again! Ice cold and my test food, froze solid ...
This morning I reintroduced the Sonoff into the equation - and perfect again ... 75-80w / 1.9kWh consumption just like the old days
* Do you think this Sonoff could somehow limit power to the freezer in error?
* Do you reckon the freezer is flakey?
EDIT : Below is March and April. I don't monitor this thing all the time - but I can assume in March with the dips, it was during load shedding.
