Yeah, some Zigbee sensors do have a sleep mode, which can slow them down. If you’re looking for instant reaction, look for models with fast wake-up times. Good luck setting it up!
I switched from PIR motion sensors to Zigbee mmWave sensors, and it’s been great. No sleep issues, no battery changes, and the lights stay on if people are still in the room. They turn off right after everyone leaves.
