Replacement window and door sensor

Devices & Integrations

I need to replace some of my Iris window & door sensors that will not work anymore. What is a cheap replacement since the Visonic MCT- 340 is not available.
Thanks, Mike

The non-“E” version will work too, but will pair as a thing and you can change the device type to smart sense.

though note groove/IDE will be going away soon and some 3rd party sensors will need their own edge drivers which wont be immediately available until someone ports the old code.

I’m just wondering what the failure mode you are seeing with these. I have 40 of the Iris v2 contact sensors in my house, in use for between 18 months 5 years. None of them have stopped working. (I had one Iris v2 motion sensor fail, but only after I dropped it).

interestingly, the SMA version has SmartThings Edge support but the E version doesn’t

My problem with them is I can not change the battery. Every time I go to change the battery they go offline & will not go into pairing mode.

That’s strange. I’ve had some for years with multiple sets of batteries that work fine. I’d try a couple things:

  1. turn off zigbee secure mode
  2. reset the device and re-add to SmartThings. No need to delete from SmartThings. You reset by holding the small button on the side while inserting the battery.
