Okay so first of all, this unit is great. It includes a temperature sensor, light sensor (measures lux in the environment), and of course a motion sensor. It operates off of batteries which, after more than a month, still shows as basically 100% in the app. The batteries are 2x AAA, so easy to replace when needed. Since it's battery operated, you can put it anywhere without any install unless you want to permanently mount it somewhere. You can adjust the sensitivity of the sensors so they trigger actions more (or less).From the Hue app, you can set how you want it to behave. Only want to enable it when the room is dark (determined by the light sensor and whatever trigger value you set)? No problem. Only enable it after 10pm? Sure. It's quite powerful.There are some missing features that could be implemented though, some of which do have workarounds. And accessing the raw data (sensor states and values, etc) is actually quite easy with the Hue Hub since it has an accessible REST API. So here's my situation, and an example of how I was able to work around a missing feature that I wanted.The Goal: This motion sensor sits in my bedroom to turn on all of the lights when someone walks in or is active in the room. It needs to "see" most of the room because I don't want dead spots where the lights just shut off because it can't see I'm in there. However, I don't want it to ALWAYS turn on the lights when it senses movement, because even at the lowest sensitivity setting it "sees" when I move in my sleep and causes the lights to come on.The Missing Feature: While you can turn the motion sensing of this unit on and off via its settings in the Hue app, there is currently no way to completely disable the sensor. Sure, you can say "From 10pm to 6am, when you detect motion, do nothing." That effectively gives you the same result. But it doesn't work for the problem I'm trying to solve, because what if I go to bed late? What if I get up early? What if my fiancée wants to sleep in longer than me and I inadvertently trigger the lights when I get up?The Solution: My house primarily utilizes the HomeKit ecosystem (i.e., Apple Home) and it integrates with Hue allowing you to complete some actions/automations/shortcuts with calls to Siri or by activating them manually via the Apple Home app. It doesn't support the motion sensor directly, but I set up a Raspberry Pi running Homebridge to create a "dummy switch" with the name "Motion Sensor". I then created two shortcuts - one that submits a REST API call to the Hue bridge to completely disable the motion sensor (leaving the others intact), and one to enable it. I then set the "Motion Sensor" switch to call one of those shortcuts whenever the switch is toggled. I added it to the Bedroom zone, so at that point I could enable/disable the motion sensor with Siri: "Siri, turn off the bedroom motion sensor.") Apple Home already has a couple of default Scenes that you can modify to suit your needs, one of these is "Good Night". I added the "Motion Sensor" dummy switch to this scene with instructions to toggle it off.So now, I can say "Siri, good night" and it will turn off all of the lights in the house, turn off the TV and fan, and disable the motion sensor in the bedroom. I then created a similar "good morning" that turns the motion sensor back on (among other things) when we're both awake.
