OSRAM Smart+ Motion Sensor, ZigBee Motion Sensor, for the automatic control of Light, integrated Temperature Sensor, Directly compatible with Echo Plus and Echo Show (2. Gen.)

Let me start this by saying I don't have any sort of Osram hub to connect this too - I bought this as a way of having a cheap button for my home automation set up (only £10 when I purchased).Positives? Okay, it's a cheap button. It has at least 5 inputs. So there's something. My provider of choice to link it too was SmartThings, and out of the box SmartThings doesn't recognise it as anything, or capable of doing anything. It literally calls it "thing", which isn't very helpful. But it is a Zigbee device and it does connect, so after a bit of writing a custom device handler to interpret it as a remote control and a smartapp to link it to my devices I've kind of got it working. But that was an hours long process if you're not even aware of what a SmartThings device handler is I wouldn't recommend even touching this.Even after all of that, it's inconsistently slow to respond. You expect the green LED to light up as soon as you press the button to show it knows you pressed it. And sometimes it does. But the rest of the time it takes between 1 second and 30 seconds to decide it actually wants to do something. 30 seconds. Yeah. So, a mediocre switch in general it seems.On the plus side, it was cheap, and with the device handler I wrote (that treats it as a remote control) the battery seems to be chugging along just fine unlike some other reviews here.

This is just what I wanted. Simple to set up with echo show without the need for a hub - just pull battery tab out then search for devices on alexa. You can name it whatever you want and then set up a routine when it detects motion (Turn or lights, make announcement etc). Thermometer seems accurate enough (I have a 0.7 degree difference to the thermometer I was comparing it against, which could be inaccurate anyway) and reports temperature to 2 decimal places. You can also set a routine if temperature gos above or below a certain temperature which I may use in winter in my unheated utility room. Packaging says battery (3V lithium CR2 battery) lasts 2 years, though I can’t comment on that yet.It’s worth noting that you only need one zigbee enabled Alexa device in your home for this to work on all you alexa devices in the home

These are tiny sensors that are very easy to set up and can run routines based on either motion or temperature. I have one in my garden lean to under cover so I can ask Alexa what the temperature is outside without getting out of bed. It also activates a light so we have a motion triggered light when it's dark outside.I have another in the house that sends me a message when it picks up motion while I'm at work which gives great piece of mind.

So my search for the perfect zigbee smart switch must continue as this one has some major issues when set up through the Echo Plus as advertised.Firstly the instructions are all but useless and I only managed to find out how this switch works by trial and error and lots of internet searchingSecondly when you do eventually manage to have the Echo Plus find the device there is absolutely no way to configure it through the Alexa App so it just turns on every zigbee device you have at the same time (warning this includes sockets).Thirdly direct pairing with the switch to the bulbs without the hub will work but you then lose all voice control to any bulb you pair with it.In short unusable with Echo Plus alone.The best switch I have found so far is the Philips Hue switch and that's not supposed to work at all with Echo Plus but it does and realy well too. It's just such a geeky shape and wont fit over a standard light switch box without an ugly adaptor.Amazon you must amend your description.

Edit:Now getting constant false positive alarms day and night from 2 out of 4 of these. It particularly favours making the alarm go off at 3-5am and when we’re away.New batteries, hub reboots, delete and re-add, no change.Absolutely brilliant. Pull the battery tab.. add device in app.. name device.. crack on. I had a four pack up and running in less than 5 mins. Nice little mount and instantly worked with my ST hub v1! Not one false pos.I also love that these aren’t a button cell as I’ve had to hack my ST motions over to AA batteries to stop false alarms.- I also love that there is a small green not too bright LED upon motion.Wish I’d seen these earlier. I’m going to design and 3d print a ball joint for these.Edit: as ever with gadgets sadly this has one flaw. It for some reason doesn’t trigger Alexa correctly;Smartthings sensor switches on any light I have, hue or plug switching upon motion.Swap that motion sensor for this.. and I can only control brightness with tuya bulbs (upon motion in an Alexa routine), and the power switching has NEVER worked once. On any Wi-fi power or bulb! Oh well. Main purpose being security at this cost I’m still very happy.For those screaming at the screen just use a virtual switch in ST for the tuya.. it doesn’t work and tuya are coming away from st and ifttt and disabling features.
