CombossWiFi Motion Sensor, Smart Motion Sensor, Presence Sensor, Works with Alexa App, Echo Devices (1 Pack)

Not all floor to say about this product other than it absolutely work perfectly easy set up quick and easy integrates with Alexa via smart life... For the price this is really good effective and efficient... Allows us to link movement to lights via Alexa routines... Would definitely by again

Very happy with this motion sensor. Works well with Amazon Alexa routines.

Item is fab, does exactly what i needed it to do.Would have been 5 stars, but one of the 4 has stopped working, despite battery changes etc. It's not a massive issue, but it's irritating.Anyway, they were easy to set up, haven't lost connection at all, and just work.We have them set up to switch lights on when people walk into a room, and that's what they do.They are small enough to not be particularly noticeable, and have solved a few, not particularly important, problems.

These work well as Alexa enabled sensors. They do however take a couple of seconds to kick in.If you don’t need instantaneous response on an Alexa routine they are okUpdate. These are now no longer working properly. 3rd set of batteries from oct sometimes they detect sometimes they don’t.

Pairs fast, but I thought it will detect me and recall a scene within a second or max 2 seconds, this takes at least 5 seconds, which is about as long as it takes me to walk up the stairs, so I get the lights switching on when I don't need them anymore

Despite their basic look, these work really well, much better than I expected (they're actually a little too sensitive for my needs). When I first set them up they were very laggy on responding to motion with Alexa controlled devices, but after a few hours they seem fine.

would get again

Work at first but after about a couple of weeks, it stopped working and tried resetting and couldn’t get it to work again so sent it back
