Hi everyone, I’m trying to create an automation but I can’t do it as I would like.
I have a technical room where I have these 4 devices
(Boiler, refrigerator, freezer and washing machine).
Being a dedicated power line, I put a shelly EM upstream to monitor the current draw of that power line.
Since it is a room outside the home, I wanted to make an automation that would notify me in the event of a power failure.
I tried to set an alert when the absorption was equal to 0watt for 120 seconds.
This summer it worked well, but now that it is cooler it often tells me that there is no power.
So I investigated and I realized that this summer it was working properly because the refrigerator or freezer were almost always in operation in the heat.
Now that the cooler and the freezer work less when it is cool, it often signals me that I am consuming 0Watt so there is no electricity.
How can I make an automation that signals me the actual lack of current?
