MmWave Human Presence Sensor,Zigbee Millimeter Wave Radar PIR Wired Motion Sensor,Requires TUYA HUB,Support Home Assistant via Zigbee2mqtt,for Indoor Home Automation

Most of the negative reviews here stating this is not a Zigbee device are half true. This device is a Zigbee device, but it does not expose all its entities in ZHA. You MUST use Zigbee2MQTT, which I went through the grueling frustration over the past month trying to figure out how to set up with a second Zigbee radio device connected to your Home Assistant setup. I run HAOS on an Raspberry Pi 4 with a Conbee Zigbee/ZWave stick and a SkyConnect (they've rebranded this as a ZBT-1, I believe). You CAN run two Zigbee radios on one RPi4 in case you are wondering and it is very frustrating to set up, but once you figure it out, it's worthwhile. These little presence sensors are basically a better motion sensor that uses MmWave to detect movement and presence, which is far more effective than the standard ones, but not as in-depth as ones like the Aqara FP3, which can count bodies in a room and where they are. These fit my needs better than the ones that are more in depth, so I'm giving 5 stars with the caveat of you will have to have Z2M installed and working in order to get the most out of these.

These are supposedly the same millimeter wave devices I purchased before that work flawlessly. However, these are complete garbage. I set the minimum and maximum trigger distances, but the device ignores the settings. Arbitrarily, I set it to a minimum of .75 m (2.46') and a maximum of 2.25 m (7.38'). It triggers between 0 m (0') and 1.6 m (5.25'). I walked around with a tablet, with home assistant open, watching the target distance. Standing on top of the device, it says I am 1.3 m (4.27') away. I take 3 steps away and the device goes to 0 m (0') and triggers "Away". I've adjusted the sensitivity settings enough to get it to kind of work as long as I'm within a few steps of the device. However, I can't think of any room in the world that that would be useful in.On top of all that uselessness.... The settings seem to restore back to default within an hour of me changing them. I've changed them many times, just for them to change back to being completely useless. With the default settings, I can dance on top of the thing and it will keep sayingAway".At this price point, I don't expect perfection...but I did pay for it, so it should at least be usable.

It works as described but is very spammy on the zigbee network

Won't go into details as many have said what needs to be said.I will say that it's lacking induction / trigger duration, which I've seen others have. So, you can't set automations based on trigger duration. As an example, I can't set it to "trigger when there's movement for 5 seconds" or "trigger when there's no movement for 30 seconds", etc. It's straight up "trigger when movement" or "trigger when there's no movement". I wanted this to activate some lights when it detects movement for 5 seconds and turn them off when it detects no movement for 30s, so, no go.Otherwise though, it seems to have everything else and does work well.

Saw this on sale and gave it a shot. Worked immediately and easily with Zigbee2MQTT with HomeAssistant (if you're using anything else, stop being a masochist). It is inches away from an Aqara FP1 and pointed at our bed/walk way to the master bathroom.For the most part this sensor picked up passing occurrences better. I also see that the FP1 had regular disconnections, something an FP2 in our Livingroom also does. Seeing this, I think I will get a couple more of these in the future if I don't build myself.

This is not a functional Zigbee device. Although it appears to use the technology under the hood, it does not interoperate with other Zigbee devices, like the hub you already have for all your other Zigbee things, including HomeAssistant. You will be able to see it but it will not provide any controls or sensors.Supposedly if you buy their "special" hub you can control it via MQTT, however unless you are experienced with self hosting and configuring web services you will NOT find that to be SIMPLE.True "Zigbee devices" can be used with a Zigbee hub. Allow me to paint a rough picture for you: This situation is analogous to selling a "USB device" that requires a special box and can't be used with a computer. True "USB devices" can be used with a computer.

I use these sensors (I have several at this point) to automate my smart home. These are a great step up from motion detection. The sensor exposes a number of settings to fine tune performance (min/max range, sensitivity, fade time). Overall, it's been very accurate with extremely rare false negatives. It also comes with a light (lux) sensor.

These things work GREAT-then they don’t, Then great, then not at all. Too unreliable. Impossible to place.Paired up fine all things seen, had to restart HA to get all sensors to show.
