Hi, I have this cheap PIR Sensor and would like to inform that it works OK with RFXCOM and Domoticz:

(Look for the PIR sensor in the link above)
The protocol is Lightning 4 (PT2262) Motion Sensor and can be learned by Domoticz. The device seems to send with two codes but only one is required in Domoticz to make it work. It sends 28 frames(packets) when motion is detected and no OFF signal, so use the OFF function timer in Domoticz. I use a timer configured OFF after 60 sec.
Note that the sensor is sending MANY frames/packets so it should only be installed in rooms/area where you have very little (or no) movement normal movement. I have no information about battery life as I just installed the device (late dec. 2017).
