Smart smoke alarms with dumb smoke alarms (EU/Ireland)

Bummer! I guess I can try that one , I can’t really find any other dry contact zwave on the market and I am not sure I can short circuit the door contact.

I ordered the other one before seeing the post about dry contacts. Will rig it up and see how it works.

I have to say , I am not on the smarthings platform , I am a Vera user, but you guys have been most helpful! Maybe I should look at switching hubs.

Finally got the items for this project. I am struggling with determining what T1 and T2 is on my dry contact sensor . This is what it looks like.

Thanks!
Just to make sure I understand correctly. I have to power the dry contact using L&N.
I use the blue and orange from the SM120X to connect the 2 slots on the right of dry contact
I also connect the Black , red , white, on the SM12x to the smoke alarm

Does that sound right ?

It appears that the dry contact does indeed need to be powered to work . I don’t want to deal with another high powered device I would need to hide in the wall so I am going to look for another dry contact that is battery powered or use a door sensor like you suggested .

Thanks everyone! Will try that out

Back to DIY fun. I
have my gocontrol zwave sensor now. I believe i see the input for the wire as pictured below . How do I put this all together now ?
