Excellent switch, does not require neutral wire, the comma resistor also did not connect, everything works perfectly.

Easy to set up and add

Fast delivery and according to the description

Works wonderfully. Careful, the alarm is really loud!! E-mail notification and SMS-(you need a SIM card that is not included) also work. Overall, a great system that is very inexpensive. Batteries are included in the ÖR sensor and also in the door sensor (see Picture door sensor battery). It must be said, however, that it is difficult to get to the battery of the door sensor, that could be better, but you shouldn’t complain about the price…

Product arrived ahead of schedule, well packed, I put to monitor the two phases (220 V) I only need to monitor because a channel is as reverse and does not change, would be to measure the energy injected into the network for those with solar plate.
