First Alert New 025 SMCO410 Z-Wave Battery-Powered Smoke Detector & Carbon Monoxide Alarm

Let me start by saying I don’t have any SMCO410 detectors.

I currently have 3 ZCombos of various vintages. 2 of my 3 ZCombos are connected using ZWAVE_S2_AUTHENTICATED and are working with the “Z-Wave Smoke Alarm-Mc” driver, so I don’t think S2 security is the problem.

What version ST hub do you have?

I have a number of the first Gen ZCombo’s that work fine. They do not support S2 though. I only mention a potential S2 issue because that is the step these seem to freeze up on during pairing.

I have both a v2 hub and a v3 hub at my primary location, my security devices are connected to my v2 hub. The issue with the “offline” messages from my remote locations has resolved itself in the last couple of weeks. I just added another ZWave Combo Gen2 smoke/co detector to my 3rd location where I only have a v3 (Aeotec) hub.

Thanks for responding! To save everyone time, it appears that you need a v3 hub for the SMC0410.

What specifically would lead you to believe that? What limitations would other hubs have that would prevent this device from pairing?

Nobody with a V2 hub has got the SMCO410 to connect.

Yeah.. just bought the smc0410 from costco deal last week and looks likely i got stuck on processing screen even with Andreas’s driver. V2 hub..

Was going to try for myself but it seems v2 is a nogo for some reason.

I’m a little unclear - do these truly work correctly with a v3? I understand that you can get them to pair, but has anybody been able to get them to work with a v3 hub without the constant connect / disconnect warnings? If I’m reading this correctly, only Bruce (bbailly16) has had success, and that’s only with special replacements sent by First Alert?

it’s really sad as the old generation of first alert smoke detector was working fine with my v2 hub.

I have two currently connected to a V3 hub with no problems.

Just following up with my experience… Purchased two from Costco, both seem to be working fine with the V3 hub. Manufacture date was Jan ‘26 if that matters. To get them in pairing mode you have to hold the button down on the detector for about 20 seconds (keep holding it after it beeps once until it beeps a couple times). It’s been over 24 hours and neither has disconnected.

How did you pair within the app specifically? I got in on same Costco deal and installed both yesterday, but haven’t been able to successfully pair yet.

It was a bit frustrating - I love how the First Alert instructions say to check the SmartThings app, and the SmartThings app says to check the First Alert instructions…

If I recall correctly, it was:

  1. Hit ‘+’, then ‘Add device’ in the SmartThings app.
  2. Select ‘Scan QR Code’
  3. Can’t remember exactly what the app says then. I think you have to hit ‘next’ or something so it’s ready for pairing mode.
  4. Hold the test button on the detector for about 20 seconds. After about eight seconds it’ll beep once - don’t let go or it’ll just go into test mode. After about 20 seconds you’ll get two beeps (or something like that). Let go of the button, then it seemed to take about 5-10 seconds and then the app brings up the usual screen about what you want to name the device, etc.

Hope that works!

It worked. Thanks so much! Not sure if it was necessary, but I did bring each unit close to the hub (within 5 feet). Worked very fast and I’m glad I didn’t have to mess with 3rd party installations.

Smartthings: The smart home platform for those not afraid of fire.

The navigation you describe appears to no longer exist - no “Tools”, and I can’t find anything called “Edge driver builder” in the developer console. Do you know how to get to this now?

Thanks.

@junrau They have changed the portal since my post. It still works though. Try this URL for the Edge builder: SmartThings. Add a little smartness to your things.

Thanks! That let me update the driver and capabilities. I will test the alarms’ functionality later today.
