Kerui D026 instead of the Sonoff DW1

Last weekend I got the Kerui D026 door and window sensors that I ordered to use instead of the Sonoff DW1.

As can be read in my previous post, the DW1 does not send a 'closed' signal, therefore I ordered the Kerui that does send this signal. It works like a charm and now my next big upgrade will be to get my alarm system up and running together with this Kerui D026 and the Sonoff Pir2.
