Sorry, must’ve missed this.
Yes I did get this to work and its been working fine. I added to the network in a much older version of HA (don’t remember which version off hand), so not sure if newer versions may have a problem adding the device.
These controllers are designed so you can run it as a primary and then add additional units as slaves.
This should be what you need to do to add it as a slave:
Main Menu > Network > Join Network
If you already have the unit mounted outside, it might be a signal issue since it needs to go through the exterior walls.
Might try putting a powered repeater at a halfway point.
I remember having problems with that initially, but added an outlet for my coffee maker in the kitchen and that did the trick. Have added more powered Z-wave stuff so the network is more robust now.
These units are unfortunately standard Z-Wave, so they do require polling. Wish they’d come out with an updated version.
