I want to monitor the power usage of my washer drier with this but I'm worried it wont work, or worse overheat/shutdown mid-cycle. Any horror stories?

I use mine to monitor my partners ironing usage. When she takes too long and uses too much power, I give her a hard time and tell her she must get it done quicker. I think she loves the feedback, and it helps us reduce our family carbon footprint! Win win!

Thanks- i was asking about a 1kw heater, about 4.5 amps....qrtr of 16a. also, if i wwre to use contactor, can you plz recommend one?

I'm using Shelly 1PM with an 80L water heater that consumes 1500-1700W while actively heating since a year without any issues. You should be fine..

Does this get warm? I want to place it in a surface box behind a room thermostat that controls a heated floor.

It’s a dry relay so shouldn’t get noticeably hot. They are designed to live in back boxes.

Good for low power items. Found it overheats in boxes using 3000w items but software detects it and shuts down accordingly.
