Received OK. Buy WIFI VERSION only meter. It has NO switch. Surprised the variety of functions it has. Measures all electrical parameters and further records them in graphs. I do not know if the precision will be correct or not, but for a domestic use it is more than enough. Comparing to another one I bought before from another manufacturer and at the same price this RS much better apparently. I just put it into service. I will put information back once A little time passes

3-5x quick pressing Test Button for pairing should be documented somewhere… other than that good quality for the price

It arrived very quickly. Thanks to seller

There is experience of using such a switch, which has been operating for 6 years, differs in switches on trims, this one clicks with relyushki. In principle, it works fine, but there are nuances if LED lamps with a filter will work without an additional capacitor, if the cheap lamps will most likely need to add a capacitor. The biggest minus for me is that the remote forgets when the power is turned off, not a single dog wrote in the reviews.

Motion detection does not work. set the highest sensitivity, but still does not respond to any movement. the removal and re-installation did not help. how the call works great.
