I have a relatively simple setup that suddenly stopped working and I have no idea how to start debugging. I have a single Hubitat hub in my basement to control one GE 40 amp Indoor/Outdoor Smart Switch connected to my low-voltage outdoor lighting. I have an Aeotec Range Extender 7 to carry the Z-Wave sufficiently strongly to the Smart Switch. I have the Hubitat app running on my iPhone 14 pro, using a simple Basic Rules to turn the light on at dusk and off at 11:45pm. The lights suddenly stopped going on. I downloaded the latest firmware to the hub. It seems to be working and the LED is glowing green. I checked the Smart Switch and it is getting power and I can manually turn lights on and off. Left switch in down-most = position (versus O or -). In the app, I click on "Tools" / "Connect to Hub" / "Devices" /"Low Voltage Outdoor Lighting". Then, when I click the "On" and "Off" buttons, nothing happens with the outdoor light. Doing this used to manually turn the light on and off.
If your manual control from the Device Details page is not working:
Then I would expect it is something to do with HE being able to either communicate with or more generally control the switch. Just rule out anything that could be happening in the HE mobile App, try the same process in a web browser on a PC or laptop, i.e. open the Devices page, find the switch and try the on/off commands.
I'd then try turning on the debug logging for the device, if there is a Preference Setting for this available, and click Save Preferences. Then open the HE logs page in a separate browser tab (there's a link at the top of the device details page) and watch the Live Logs while you try the on/off commands again. If anything comes from this, post the results / logs back here.
You could always try either a reboot of the HE hub, or potentially a shutdown for say 20 minutes and restart, this can sometimes force devices to re-establish communications in situations like these, though I'm not as familiar with Z-Wave.
Beyond these steps, it will likely be others who can help you more than me. They may want to know the driver you are using for the device, as well as any more details you can provide about your Z-Wave setup / settings on the HE hub.
- Do a Shutdown from the Menu (Settings -> Shutdown)
- Remove power from the hub.
- Wait a minute and restore power.
I tried the shutdown and then remove/restore power but that didn't work. I tried turning lights on from Device page on PC (not phone), and that also didn't work. (I was seeing the same things as on the phone. BTW, I also tried from app on an Android phone but no luck.)
When I clicked "on", I got the following in the Live Logs display (I had to remove links to post):
[dev:3] 2023-08-07 06:13:05.352 PM [debug] re-sending supervised session: 8
[dev:3] 2023-08-07 06:13:00.298 PM [ debug] new supervised packet for session: 8
[dev:3] 2023-08-07 06:13:00.292 PM [debug] on()
Now that you have rebooted try to change the switch state a few times. Then under settings go to the Zwave details page and take a screenshot of what is shown there and post it here. If you see a button for Zwave firmware update do that, and repeat the powercycle process with the power pull to ensure the zwave radio fully restarts.
I indeed saw a button for Z-Wave firmware update, so updated it, then shut down and power-cycled the hub, and now everything works again. Thanks!!
Arrgh! I stupidly messed things up by trying to also connect my wife's iPhone using my login. (I now realize I should have made her a separate account.) Now the lights don't work again. I tried, from my PC, removing all phones from the system, then uninstalling hubitat app from my iPhone, power-cycling the hub, then re-installing the app and logging in from my (single!) iPhone. The on/off buttons still do not work. Nor do they work when I try turning the lights on and off from my PC. I no longer have the option to do a firmware update on Zwave so can't try that approach. Any advice greatly appreciated.
Please do this.
After 12 hours or so, the lights magically started working again and everything has been fine. May not have had anything to do with the phones? In any case, thanks for your help.
