Deal Details
Google is no longer selling the Nest Protect and the official alternative are these First Alert SC5 Smoke and Carbon Monoxide detectors. Elsewhere these sell for $129.99 each, Costco has them on sale as a pair (2x) for $159.99.

Both the Nest Protect and these First Alert SC5's expire after 10-years, I have several due to be replaced so I swapped out 2 back in October and they can use the same mounts left behind by the Nest Protects (at least the battery version).

They do not appear in the Nest Protect app, but they do show up in the Google Home app where Nest Protects also appear, and they also support the Wireless Interconnect which allows them all (Nest Protect & SC5) to unify and announce where an alarm may be going off.

If you use HomeBridge with Apple to connect into Nest Protect, these currently do not appear to have that type of support. The current HomeBridge for Google Home also do not appear to support the SC5's.

Also, these SC5's use a different battery type and do not offer the pathway lighting.

Yeah, the false alarms reported on reddit aren't giving me confidence.

I don't understand why it's so hard for these manufacturers to make a good hardwired unit that does pathway. Don't a ton of homes have hardwired detectors these days? Battery just as backup. Pathlight wouldn't be a drain on a hardwired unit.

i know you said these do not work with apple's homekit that well, are there good wifi smoke/carbon monoxide detectors that work better with apple? looking to replace all my old school units as they are expired and have been having a tough time figuring out what to get. It looked like either this or kiddie were my only options - is that right?
we are insanely light sleepers though and need the ability to turn off lights or at least cover it up somehow if possible - can i do this with these or the kiddie?

I can tell you first-hand the false alarms are a problem - 1am wakeup, all the kids woken up in whole house, after replacing nest protect with one of these. Returned after that. Going to try the one by Place home solutions now.

Wish they had the night pathway light added to this unit just like the Nest protect had it.

Checkout the one by Place home solutions, it has path light. Just bought some, we'll see if they're any good

I have two of these, one battery, one wired; no issues with false alarms but I will say they are not quite the same polished product the Nest ones were. They do work well and integrate nicely into Google Home and send notifications, emails, and such when they go off.

Yeah, I think I'm going to wait until a V2 of this product.

I'm still salty with Google for dropping the Nest Protect. They're famous for dropping hardware- makes me not want to invest in their ecosystem anymore.

If they were hard wired you would only have to buy 1 unit to get the notification. This way, you have to fill your house with them.

Thank you for such a well written deal detail; it sums up this detector's shortcomings well. Deal or not, I'm holding out for something at least as good as the hardwired Nest Protect units these would replace. I even wrote First Alert when these were first announced and told them so. If I'm paying a premium for a detector like this, then they had better be able to detect smoke and CO well, AND have pathlight at a minimum. I'm fortunate because my oldest Nest Protect's "replace by date" isn't until 2/2031. I bought those from Costco, so agree they often have good prices on smoke detectors.

the reviews about this and the false alarms in general seems pretty bad. I had to get a nest replacement, i decided to go on ebay and buy another nest protect new which 8 years left on the expiry. I paid a bit over for it but i didnt want to have to drill a new plate into the ceiling. Some caution, do confirm the expiry of the alarm is in the description of the item or confirm with the seller.

They stopped making them earlier this year but the ones they made up until that point have 10 year expiry so 2035. The best i could find at the time was November 2033. The expiry is printed on the unit. The serial number can also be derived to determine expiry (upload ebay picture of serial number into grok or gemini for example and ask for expiry). Do not buy any unit new or old without confirmation of expiry date.

I have seven hardwired Nest Protect that will eventually need replacement, so the price is not insignificant. Good to see that First Alert provides the option of battery or hardwired, and kept the same ceiling mount. Also good to know Costco carries them. Now just hoping First Alert get it totally right with a V2 model.

The pathway on the battery Nest units wasn't much of a drain either. Even on the one that got a lot of traffic we've only had to replace the batteries once in about five years of use.

I agree about it being important to check expiration when buying old stock Nest Protect, but that does seem like the best solution for those close to expiration. Checking your current units can be done from the Nest Protect app by drilling down in settings for each unit and checking within "Technical info" for each unit's "Replace by" date.

FWIW for anyone else worried about false alarms: I think it has to do with condensation, so be cautious
I bought 2 of them, only 1 gave the 1am ringing problem - I believe the cold (this was in the 2nd story in Colorado, i.e. some exposure to the cold above) results in condensation on the sensors
It explains why I only had the problem with one - if you're not in cold weather, you probably won't have a problem
