Battery operated PIR sensor to work with RM Pro + Home Assistant

Hi guys,

I have all my lights rigged up to my RM Pro and am looking at adding a battery operated PIR sensor to turn on the light switch that controls my porch lights. I dont want any bridges/gateways just a sensor that works out the box with Home Assistant. I’ve seen the new WIFI ENER-J PIR sensors and was wondering whether that was the best way to go? Total newb, just looking for some friendly advice. Thanks guys!

Does anyone know of any battery operated WIFI PIR sensors that don’t rely on any sort of bridge or hub and communicate directly with the router? Is it possible?

I was considering these for PIR:

Any one have any experience?
