As for your office, since this is in a separate building, you will run into a number of different issues, including weather, regardless of whether you use zigbee or Z wave.
See the following:
I have a detached metal shop that is approximately 10ft from my house. Line of site from the hub to the nearest device inside the shop is probably around 35ft and it’s going from a closet that houses all my tech (file server, router, modem, POE injector, home theater tuner, etc) through a wooden door, through a rock wall and finally through the side of the metal building.
I have two garage door openers (GD00Z-4 & FS20Z-1) inside the shop that work, but are very inconsistent.
I’ve installed an Aeon smart switch 6 that wasn’t being used on the outside wall toward the shop (interior of the house) then ran a zwave repair and that didn’t seem to help.
I’ve looked into a Ethernet bridge but I fear I’m not smart enough to figure out how to set it up (they look incredible confusing).
What woul…
