Cool. Glad it worked for you.
I can’t get my v2 hub to connect, exclude or otherwise interact with the SMCO410. If I upgrade to the Aerotec v3 hub, do I still need to install Andreas_Roedl’s “Z-Wave Smoke Alarm (Snapshot First Alert 2025)” driver? Thanks!
Update: I replaced my v2 hub with Aeotec Smart Home Hub v3 (S2/Gen5). I was then able to pair the two SMCO410 from Costco. Follow Mykines instructions above to get the device into pairing mode. Here is something to keep in mind; if you scan the QR code on the device, you get an insecure connection and must exclude it and try again. The trick is to scan the QR code on the “business card” with the DC DSK info. It then pairs perfectly and no need to enter the 5 digit pin. The stock driver works fine. Too soon to tell about stability. Good luck!
I can confirm this works with the V2 hub (and apparently still the only way to get it working). The links changed, navigate directly to the Edge Driver Builder here.
Have 2 smco410 paired with an v2 hub now. Took a bit to get them to show up as a device . First one listed as a switch. Would not let me chose a z wave smoke driver, however the edge driver builder solved that issue. now pairing the next one could only make work searching and after a bit showed up as a sensor. Driver choices included the z wave smoke. I still used the edge builder to modify it the same way. but they are both working and staying online for now. lots of trial and error to get to even show up as a device. had to use the exclusion function after every time. hub reboot seemed to help too. was unable to every get the qr code on back or card to work at all hangs up in verification.
