Review: Excellent For My HA Setup! - Brilliant little thing, I was actually quite surprised at just how small it actually is. Connection to Home Assistant via Zigbee2MQQT using the Sonoff dongle plus was so simple. The sensor itself is very accurate, with my current HA setup there’s no delay on firing my automations that turn the light on the instant motion is detected, start a timer, then also reset the timer upon each motion event, for consistent lighting whilst in the room, and then when no motion is detected the timer will run through and turn off the light. Obviously this is not a presence sensor, so if we haven’t moved at all in the time that the timers is set for, then the light will turn off on you, meaning this probably wouldn’t be good for the main lights in a bedroom or living room, I use this in my kitchen and it works great. I can’t definitively comment on its battery life, but I’d say it’s going to be rather good, I’ve had this for a good few weeks now and it’s still on 100%. All in all, this is a great sensor, excellent value for money and in the right setup, used for the right reason, this is a very good item.
Review: Small, Discreet, Function Well with ZHA in Home Assistant - Not Pet Friendly - I ordered these Sonoff Sensors to implement into my home assistant setup. The sensors were immediately recognised by the sonoff zigbee 3.0 plus dongle and added to my HA setup. The sensors work great with Alarmo. The sensors were much smaller than I anticipated. They work very well and the sensitivity is high, so much so that my robot vacuum cleaner set these off in the middle of the night. They are also not pet friendly, my dogs were easily detected by each of these sensors. I have had to angle these up towards the ceiling in order that they do not catch the floor area, thus moving them out of the range of my dogs and vacuum. Even though they are pointed upwards they do still detect a human presence which is great, the issue is the range is just not as good now. The sensors can be attached by magnet to a metal base or by the included 3m sticker, or with plain old wall screws. In summary for a home without pets or robots these would work great, either as an alarm sensor or as a PIR for lighting ect. ZHA does not allow the changing of the cooldown time, so you are stuck with 60 seconds. There is a workaround available however this did not work for me, and no matter how much i tried to reprogramme the cooldown time in ZHA the controller failed to write the new parameters. One other thing of note is that the motion sensor sensor in ZHA is always 'detected' so you can not use this, however the 2nd entity exposed is occupancy, this is what you use when implementing to ZHA. I hope you found this review helpful

### ⭐⭐⭐⭐ Not the cheapest, but 100% worth it.
*by P***N on 22 August 2025*

Brilliant for the bathroom to trigger my Aurora lights on HA automations - works perfectly, have also set up a "bypass" so I can keep the lights on longer than 2 minutes if having a bath / extended bathroom visit. Cant complain at all, superb.
