    This easily integrates with the ring system. Thank goodness I have not had a fire or carbon monoxide issue for a real life test of the system but I can't see why it wouldn't work ss advertised.

    Understand these are not made by Ring and therefore set up in the app is not as clear. Each detector ends up with two icons, one for the fire detect and one for the CO2. Battery level status is green but not percentage.

    Attached to my SmartThings network quickly. Works well. Battery life not the best but if you change your batteries for Daylight Savings they should be fine

    Very good system. I have one in a loft above the garage, and another by the bedrooms. We did have some false alarms because we had the windows open when some intense fog rolled in, but other than that they work great.

    Still not certain if this electronic version will alert when there is smoke in the house. The test button says yes but a smoky match does not set off the alarm. It has been in service for several months but never noticed kitchen smoke from the broiler!

    No, I would not recommend this to a friend
