I am trying to integrate a wired alarm siren (12v dry contact) to smartthings. Thought about lots of options to integrate this siren. The only problem is that I don’t want to be depended on internet connection (e.g. local processing) or power loss. So I have 12v constant power ups for that siren and I only need to switch it’s power on/off.
So I am looking for a reliable local processing low voltage relay and I couldn’t find any decent one.
The only hope that I have is in the local processing device list provided by Samsung (https://graph.api.smartthings.com/localDevice/list) where there is a line of some general “Z-Wave Relay” that marked - Local processing: TRUE.
What is that “Z-Wave Relay” can I use any relay with that DH (Fibaro relay or Quibino relay).
Any help will be appreciated.
