I was using a GoControl FS20Z-1, which worked great until the change. I would love to hear that it will work again… but it is 7 years old. Anyway, that one won’t work, what should I change to that will work with the new system? Was looking at Shelly Plus 1, but it doesn’t say it works. Any suggestions would be appreciated.
You would have to ask Shelly support about what is available through the official cloud to cloud integration.
There is a community-created edge Driver working with some of the Shelly devices. You could check in that thread to see if the dry contacts option is working with that.
I’ve been searching the forum for potential replacements for my fibaro v1 door sensors. They’ve died and I used them for their dry contact inputs, which could trigger a smart things event.
