Edge, Aeotec Group, TriSensor.
And this is the voltage buck:
But honestly if you are going to be buying the sensor I would just buy one that is USB powered
like the ZOOZ Z-WAVE PLUS S2 OUTDOOR MOTION SENSOR ZSE29 VER. 2.0 (BATTERY OR USB POWER)
Or Aeotec MultiSensor 7
I have 12 Volt camera power supplies that I connected to for the DC power
