I made the mistake of moving my Homey thinking I could improve the performance of my z-wave network. I thought I understood that after moving it, a restart would cause it to rebuild the network routes to each device. I hadn’t really explored using the developer tools to directly view the network routes of each device.
After moving it, most of my devices became unreliable. Some became unreachable, some erratic. Once I finally got around to pulling up the developer tools view, I found several issues.
First, a number of my devices had network routes that were 5-7 hops. This is a new (2 years ago) house where virtually every room has a z-wave light switch hard-wired, so repeaters are no more than 10-15 feet apart generally - mostly various models of Zooz switches and dimmers. The longest route to the Homey was maybe 50 ft, but also one floor away. The second problem was that there were 8 “unknown devices”
So, I started off removing the unknown devices in the developer tool. This took a while. The “remove all unknown devices” button didn’t work, so I had to go one by one and remove them. After I got that done, I restarted the Homey again, and the routes got better, and things started working consistently again, so I’m guessing that the unknown devices were most of the problem. I then moved the homey around until I had almost all devices down to 3 hops or less. The ones with 4 hops are less critical, although they still seem to be reliable and fairly responsive, just a little lag.
Now the devices are all working reliably again, and respond quickly to both manual switch touches, as well as app/hub driven actions.
