RF 433Mhz Door sensor with on and off codes

I got a Sonoff RF bridge, all good now. Reads and sends correct short code.

I haven’t used the RM Pro for 433, but it looks like that needed to be changed from base 64 to hex possibly. I use the sonoff bridge and it functions awesome.

Just received four of these - thanks for the detail. I can confirm that there IS a place on the PCB for a tamper switch - four PTH in a 5mm square. If you s/c the upper left and lower right ‘holes’ (seen from top with battery to right of board), you will get a xxxxx7 code. And, yes, works perfectly with Sonoff RF Bridge with v8.2.0 Tasmota.

Yup, and I believe it sends it’s code when the circuit opens. I was going to use the 7 code for something but that action was backwards, so even though i have a dozen of those things around the house, I haven’t used that code yet. But it is there…
