Hey Tdj,
May you please advice me how did you connect Schneider wiser smoke alarm to the Home Assistant. I have no wiser hub, just a detector and not sure if I did correct steps to connect it through Zigbee.
Stor tack:-)
I did it through ZHA (Conbee II) and just added it like any other Zigbee device. Went to the ZHA integration, add device, pressed the button on the smoke detector for the right amount of time and it popped up in HA. No Wiser hub.

As Paul Haddon wrote above, it only provides some basic info. Through ZHA I see these entities: Smoke (yes/no) and temperature (not very useful as it seems to be rounded to the nearest degree and Iām doubtful about its accuracy). I also see the battery percentage.

I have been planning to buy some recently in order to test them but as I understood it you donāt get the auto-pairing of the radio connection when synced in ZHA instead of the Wiser hub, Instead you have to radio-pair them yourself.
Having dealt with Nexa rf-devices and the horrors of it I have some questions if you know:
- Does it matter which order you pair the devices?
Do you have to pair the rf-connection before adding them to ZHA, vice versa or does it not matter? - One of my largest gripes with Nexa is that it seems that you have to re-pair all your devices if you add another device to your Master in order for all of them to still notify each other. Is this something youāve (or anyone else) noticed with these, or can you add additional later on and all of them becomes synched?
If weāre talking about the Schneider Wiser detectors, the radio did seem to auto-pair. I only added them via ZHA, and if I then turned off Home Assistant and did a test, both devices beeped.
I have recently bought another two detectors and added to ZHA but havenāt checked if they have radio-paired with the original master. Will do it when I get a chance in the daytime.

Iām surprised more people arenāt using these. $40 on Amazon. Before I buy a couple of these, am I missing something?

Iāve been using them over 4 years now, all work perfectly, everything is exposed to HA natively. I have tons of automations (notifications, siren triggers, and turns the AC off) running based on them.
If there is a slight complaint, it would be that it is sensitive to steam. It must be a lot of steam, other than that, works fine with HA.

First Alert is not making them anymoreā¦ I checked last time on first alert website.
Not sure what you mean.
Thanks for all your info on this, Iāve been struggling to find much relevant to UK compliance. After much searching I found they comply with BS EN14604:2005
I already have Drayon wiser central heating, so having my alarms in same eco system would be a bonus
But here we need several interlinked smoke detectors (BS EN14604:2005 compliant), but for the kitchen, must have interlinked heat (BS 5446-2:2003 compliant) and CO (British Kitemark EN 50291-1) alarms as well and I canāt see anything on the Schneider site about any, was wondering if you knew of any?
Do you also require heat alrams where you are, what are you using?
Many thanks 
@tdj Tim, this question was actually for you, I replied in the wrong place I think 
Iām using this. Itās working not anything special but it does itās job.
I also tried tuya ones but I wouldnāt recomend them as they have some connectivity issue with z2m.
They became available only if you press button for siren to go on, but then again they became unavailable.
No, sorry. Thatās an awful lot of requirements there with interlinked heat & CO alarms. I donāt have either of these. Maybe Schneider is not the place for the UK market?
Yeah i recon this is a dead end for me unfortunately, they donāt have the product range available, shame, Iām impressed with their heating controls.
Thanks again for the info
Cheers, Iāll check them out, do they just connect via Z2M?
Yes, they do.

Iām also looking for wifi/zigbee smoke detectors from a European vendor or at least seller.
There are two requirements of which at least one I didnāt find any info for on the ones recommended:
(1) Can I trigger the sirene via HA, to (soft-)interlock / group them, meaning, trigger x, y, z in case a got triggered - or e.g. if a motion sensor got triggered?
(2) Can I silence them via HA once they got triggered (due to smoke)?
Thansk!
Spent a fair amount of time researching this today, largely just confirms above discussions, but a few notes in case it helps others:
First Alert previously made their āZCOMBOā model, a battery-powered smoke/CO combination detector that supported Z-Wave and that many folks including me seemed to have successfully working with HA. But, they stopped manufacturing new ones long enough ago that anything youāre likely to find now is either used (questionable for a critical safety device) or will expire and stop working soon after installation (three loud beeps repeating in the night, no fun). Most major retailers show this product as no longer available, though you can still find folks charging full price for them on eBay, I guess hoping folks donāt notice the age/expiration.
First Alert has started advertising a replacement model SMCO410 branded as āZ-wave Plus Smart Smoke & Carbon Monoxide Alarm Works With Ringā but this seems to largely be unavailable for purchase online or in stores. Amazon shows it as temporarily unavailable and almost all of the other where to buy First Alert products retailers donāt even show it as a valid product. So either the thing isnāt in mass production/distribution yet, or something else is going on.
There do not seem to be many or any other viable Z-Wave or Zigbee smoke detector/CO2 detector products on the market. As others have noted, there are some that are tightly integrated with major cloud platforms and may expose some sensors via those integrations, but I canāt find anything that will talk directly to HA and make sensors available locally.

I just replaced 3 expiring Nest Protects with these: https://www.amazon.com/dp/B0CP9YPWL7
I connected them to my 2.4 IoT network and then got them into home assistant using the integration from tache (thank you!). So far so good, tons of sensors exposed.

Lots of reports of false alarms in reviews of those Kidde smart detectors - howās the first 30 days been?
