I am starting to set up my new HE hub, and it has been slow going. It took my wife and I about an hour to get 4 devices added to the hub.
I am trying to add my old Jasco light switches to my hub. Some are On/Off and some are Dimmers. In both cases, it is taking forever to Exclude them and then add them to my new hub.
First, I am not sure what the commands on the switches actually are. I have tried "1 tap On" and "3 On, 3 Off", and "On Off On Off On Off On Off".
I am also not sure how long I should wait between trying the 3 variations, above, and when I should expect my HE to acknowledge that a device has been added or excluded. So how long does it take for a switch to settle down and return to normal so that I can try to either Include or Exclude it? And then, how long does it take for HE to tell me that it has Excluded or Included a device? Just knowing the wait times would be a big help.
I have a few, well several of them, and this is what I know about them, To exclude is hitting the on upper paddle 3 times, fairly close to together. And I typically hit with that combination several time. The blue led should blink.
If this doesn't work, then I hit the on and off in fairly rapid succession. This always works for me, if the first method doesn't.
Really old GE/Jasco Z-Wave switches and dimmers do not have a manual factory reset procedure at all. The only way reset those devices is via Z-Wave Exclusion. Put any Z-Wave controller in general exclusion mode, and simply press 'on' one time on the switch. If using Hubitat as the Z-Wave controller to perform Exclusion, you should see in the Hubitat logs a confirmation that a device has been excluded. With these really old devices, I had to actually bring them into the same room as my Hubitat C-4 hub to get this to work.
I have since removed all of these troublesome devices and replaced them with Lutron switches, dimmers, fan controllers, and Pico remotes.
After hours of frustration trying to add these old devices to my new HE hub, and after reading numerous posts sort-of related to this issue, I came to the same conclusion/solution that you defined above. I purchased a 100' long Cat6 Patch Cable and physically moved my HE into each room. Then I was able to easily Exclude each device, using a single "press", just as you stated, above.
