These are zwave. Without a zwave hub, they are normal CO/smoke detrctors, which is still a decent price.

With a zwave hub (homeseer, hubitat, isy, or smartthings) or a security system that has zwave (some adt, ge, vivint, etc) you can get notifications remotely, have lights turn on automatically, unlock doors, etc.

Neither google/nest nor Amazon echo have zwave radios built in. Pretty much all hubs will talk to either one.

Homekit/apple does not talk to zwave. Afaik, there are no commercial zwave hubs that work with homekit. There are a few opensource/diy solutions that can work with with homekit but ymmv.

If you dont have a zwave hub, go buy a homeseer zee2 for $99 or a hubitat elevation for $90 during their black friday sales. Both will work if your internet is down or if their servers are snafu, unlike smartthings. And neither is likely to get in some kind of weird fight with google/amazon. I personally use homeseer because they have been in the business for 20yrs so their business model works unlike Wink, which is dying. Plus I prefer to pay for some things with money and not privacy.

I would add that they work with Ring alarm systems and are fully supported by them. This is a pretty good sale for these units.

The two big standards are zwave and zigbee. I prefer zwave because it is easier to find thermostats, locks, smoke detectors and in-wall switches. Those are key devices for me.

Zigbee has more bulbs and sensors, and they tend to be cheaper, at least for now.

Why? Zwave was adopted by security systems because it has mandatory testing and certification, which are things ecurity systems like. So lots of security type devices are zwave. Zwave also has enforced levels of backwards compatibility, ensuring longevity, another plus for security systems where you want gear available for 10+ years.

Zigbee has been an open, unrestricted protocol. No testing means cheaper and less oversight. That's like a dinner bell for Chinese factories, turning out lots of white label zigbee gear. They make what they can sell, and since most US stores dont like stocking untested 110v devices, most of the factories are churning out battery powered zigbee or bulbs (which are held a lower standard). The lack of certification and compliance testing also means that zigbee isnt quite universal, with zigbee LL, zigbee HA and a barely-on-the-market Zigbee 3 which will hopefully work with both.

I also recommend choosing one mesh network (zwave, zigbee, thread, insteon) to standardize on. Mesh networks require more nodes to be healthy. One strong mesh beats two weak ones.

Plan on buying a couple of 110v devices (usually smartplugs) to act as relays. Battery powered devices are endpoints, 110v devices act as relays.

Never thought I'd say this - but I've grown too accustomed to the Nest/Google Protect's motion sensor and nightlight. Doesn't look like these have either.

OTOH, I hate supporting the data-hungry machine that is Google. Anyone got another smoke alarm that has the above features without the Google tax associated?

We have Ring alarm. Smoke alarms are Kiddie hardwired. Any advise on how these will fit in is appreciated. TIA.

Does this work with ring security system? Would it call the fire department when triggered?

Any chance you integrate your Nest Protects with SmartThings? We just bought a new place and plan to swap out all of our alarms with a smart alarm of some kind. While at first thought I can't think of automation I'd want to use with ST and alarms, I'd like to have the option. I've yet to dive into Nest products outside of GH and heard they've become pretty closed off since the Google acquisition.

TIA!

The Costco website has the "Works with Ring" image logo. This is likely the "z-combo" model number.

I am a lapsed Costco member, I logged in, and agreed to pay the $5 surcharge for not being an active member, but it still gave me the $20 off.

It is now an hour later, and they sent me an email stating the order was cancelled, with no reason given.

I just went back in and ordered again. Maybe this one will stick? Confused

Thank you for distilling this information. As a new homeowner I am struggling with what protocol to adopt for all IOT devices. Is Zwave my best bet pretty much in general? I am not an Apple user or of anything in their ecosystem.
