I have an old Linear Siren I used with my Smartthings security years ago. I know the old driver is “Obsolete”, but I can’t even get Smartthings to find the siren, even after I put new batteries in it. I thought it would at least show up in a scan, but nope.
Well, I’m guessing this device has somehow been blacklisted (if there is such a thing). I can neither add or exclude (even with the hub v3 in exclusion mode) it from my network, even with new batteries in it.
