Any horror stories?** A: 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! **Q: 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?** A: 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.. **Q: Does this get warm? I want to place it in a surface box behind a room thermostat that controls a heated floor.** A: It’s a dry relay so shouldn’t get noticeably hot. They are designed to live in back boxes. **Q: Does this work with the "Smart Life" app?** A: No, Shelly provide there own. ## Customer Reviews ### ⭐⭐⭐⭐ Good for low power items,may over heat with high amps *by R***N on 7 March 2021* Good for low power items.
