anyone looking at these be aware they seem to be easy to kill… i had 2/5 die with a small pop noise, the first had a powerboard with a 3d printer 2 network switches and a pc plugged into it… i had previously measured the total power draw while 3d printing with the computer rendering at less than 5 amps… but … and i dont know if its related to the fact that i had it in the kitchen pairing it and left the relay switched on, went to the room unplugged the powerboard, plugged it into the smart plug… and when i plugged it into the already turned on power socket i heard a pop and it has not responded or allowed power through since… shouldnt have been much power going through it as the 3d printer was physically switched off and should have only been trying to power a pc and 2x 4port switches… the second was even worse, plugged a chest freezer into it, all seemed good… turned power socket on… no probs… but when i switched the relay on i heard the same small pop, and presto i have 2 cheap chinese turds lol, the other 3 seem ok… for now lol
