Excellent workmanship! Chose from similar proposals where the description will specifically indicate the presence of the battery. A dollar more expensive, but without unnecessary hemorrhoids. Works perfectly, the backlight only works in an outlet, but it is also better-why waste a charge? And the clock works. I have not yet collected statistics. Upon arrival, the battery was completely discharged, but after half an hour everything worked as it should, the device survived the planned shutdown without failures. The order was shipped on the 3rd day after payment, arrived in 2 weeks.

19 days delivery. Tested everything works perfectly, already put it in the shield. The thing is necessary, how much will work be seen. I recommend the seller.

Producer. Excellent

One of the best ZigBee Smart plugs I have ever used, with this acquisition I get to the ninth smart plug that I buy, unfortunately, one of them did not come working monitoring power, but I will try a solution with the seller… recommend…

I use it as a garage door opener! Every call shorts the contact so the garage door opens or closes! You can legitimize up to 200 callers.
