I’ve had great luck with the First Alert ZCOMBO detector, so was disappointed when I went to replace an expired one to find it’s discontinued. Does anyone know of a solid detector that’s available in the US? Here’s what I can find: First Alert SMCO410. Apparently the replacement for ZCOMBO, but b…

Do your current detectors have hard wire interconnect? If yes consider the Zooz Zen55 that will integrate most any “dumb” detector with ST.

I should have mentioned… unfortunately there’s no wiring so I need a battery solution and can’t use the Zooz. But thank you for the suggestion. I should also note that I had looked at sensors that listen for the alarm sound and communicate that to SmartThings, but am very concerned about the reliab…

I recently bought the new Matter/Thread version of the Heiman CO detector. Where the previous Zigbee version failed in all areas (it’s a Tuya footprint with no known driver), this one works just fine with SmartThings. Onboarding was as easy as can be (just that Alexa got in the way having auto-dete…

Thanks Peter! I’m not seeing that one as available in the US, but their S1-M smoke detector shows as Matter/Thread compatible. Pardon my ignorance here as I haven’t dealt with Matter devices before… am I understanding correctly I need to either upgrade to a V3 hub or add something like a SmartThing…

[image] Using Matter over Thread Devices with a SmartThings V2 Hub Connected Things Does a Thread border router provide full Matter support? I am in the same boat as OP. Just got a “new” v3 Hub from ebay thinking I would need it to support some Matter devices I…

Thanks jkp. I don’t have any other devices that can act as a thread border router. So best I can tell it looks like there are three options (sorry, this is maybe more to get my thoughts straight, but hopefully this is helpful for anyone looking at this thread in the future…) Buy a new device of s…

Are there any US available alarms that can also be interconnected? This is a code requirement in most of the country and the biggest reason that I won’t install these “smart” detectors in my house. For me, it is much more important that all my alarms go off in a fire than gettting a notification on …

[image] KenW48360: Are there any US available alarms that can also be interconnected? Would the Zooz Zen55 mentioned above work in your situation? My understanding is that it’s specifically intended for existing interconnected systems, you just add it to the last one in the chain and it lets …

Is there a chance a Ring enabled detector can be made to work with ST? I think it’s jusst Zigbee right? edit: I have no idea how to not paste the full URL. <a href="https://www.amazon.com/Kidde-Detector-Real-Time-Notifications-Hardwired/dp/B0F7N7WGWY/ref=sr_1_6?adgrpid=1343603774068364&dib=eyJ2IjoiMSJ9.h0OXIU2TjtAvb9pegJJtaVjQNFSqI-ydIhkYh92rwfNlRD3w6B4CXP41hFg6vUprLle-19j2hlYMU49ilhL9tdeu0MBNQZqPeSpYwCpVc8PoNWAltEl9mZUdUxTjUBiauB3k0PDV9gqCpWeaAQKnlt8gI1wSerhd3hAre4-3igNadLZwU_y77SArnCGYpVwKNfXq40lDM_BC19DoBLyRPj7ky9jMacx_AiSxNQCw4c3REXn56dTg9qynvn91LZMFq-zkYPxQoTX3cAB3uU4Z4k6VKaNcTUiaAWimVOHGcjI.AtwymQ4TM14Ch6Yfp1MjisU0HPkm7kVZ9WyOhSS6yVQ&dib_tag=se&hvadid=83975475209904&hvbmt=be&hvdev=c&hvlocphy=108806&hvnetw=o&hvqmt=e&hvtargid=kwd-83975583136545%3Aloc-190&hydadcr=1395_13459111&keywords=halo%2Bsmoke%2Bdetector&mcid=4924dff24fe63541a77aca40a60fb216&qid=1767810065&sr=8-6&th=1" rel="noopener nofollow ugc">https://www.amazon.com/Kidde-Detector-Real-Time-Notifications-Hardwired/dp/B0F7N7WGWY/ref=sr_1_6?adgrpid=1343603774068364&dib=eyJ2IjoiMSJ9.h0O…
