@kahn-hubitat I have converted many battery powered motion and temp/humidity sensors to mains power via this method:
These have worked out very well. Only issue is a one motion sensor goes into pairing mode if power is cut and I have to rejoin the sensor each time. I ended up plugging the USB adapter into a smart plug so I can toggle it while starting the Zigbee join process. I dont understand why this one sensor does this because 5 others do not exhibit this behavior.
These are the temp/humidity sensors I am using:
