IN 2015 I bought 6 Nest Protects (5 wired and 1 battery). For 10 years they worked perfectly and I liked them a lot. As their expiration date approached, I needed to replace them and started looking for replacements. I found that First Alert was about to release a plug-and-play replacement, the SC5,…

For interconnected dumb alarms, the Zooz Zen55 is a nice option to consider. I noticed Aeotec recently released some new (z-wave) smoke-alarm related stuff too.

I had a Nest Protect (1st Gen) but they never opened up all the sensors like was originally discussed, so it did not do everything I wanted. When it needed replacement, it was not replaced by another... While I had that I bought multiple of the Halo smoke/co alarms, and they were awesome. Had no is…

[image] snell: EXCEPT that at least one (maybe both) are declaring themselves as expired in the Hubitat logs... Same here. Are you, by any chance, on a latest zwavejs firmware (that was pulled?) I believe I started seeing these messages after the upgrade. /hub/zwaveVersion shows 7.23 for me.

I have Z-Wave Firmware version: 7.22.2. I just ignored it anyways and never even bothered to check the forum if someone was having an issue with it or such as I figured it was most likely something with the device rather than the Hubitat.

I'm going to miss my Nest Protects when they get past their 10th birthday. I've had zero issues w/them, and family really likes how they operate & warn & voice info provided. I'll replace them w/a top-rated mains-powered/interconnected solution when the Nests age out, and planning to use the the Zen…

I currently have about two smoke alarms in every position. My house is wired for mains-powered smoke alarms that are interconnected, so I use them with a Zooz relay to detect if any one of them goes off (of course, there's no telling which one went off}. I then added z-wave ones that worked with my…
