These products come in EC format for UK and UC for US. If you order from .co.uk although in my case the spec in the order says UC you might likely receive EC and one is not compatible with the other.

This has to be the worst alarm app I've ever come accross. A web of maze without any guidance on step-by-step to install and personalize. Hardware is excellent, unfortunately I had to return the whole system after several frustrating hours of programing. Ordered a Ring system instead and WOW what a positive step up in terms of user friendliness. Not comparaison, the Ring system is MUCH superior in terms of app and install guide included right on the phone.

Worked great in the beginning but as time went on the glue started to wear off and the unit started falling off the door. (I have 6 of them and almost same with all 1 by 1)I highly recommend you use extra 3m to stick them on.

Like any other things from Yolink, you need the Yolink hub to use this. I put it on the door of my freezer in the basement, because we have loose everything one time for the door left open. With that door sensor, if the door is left open, i get a notification on my mobile app.

The trick is if you have Wi-Fi 6E is to get a hub
