Hi Hubitat Community & Staff,
New C-8 Pro user (updated to 2.4.3.155 today) migrating 40+ Z-Wave devices from X-10. 20 devices live (13 ZEN77s + 7 MP31ZDs), timers working via manual capture, but fully blocked on core functions.
Support History:
• Original request via contact form: November 5, 2025
• Follow-up email to support@hubitat.com: November 9, 2025
• Auto-reply merged into #35024 — no human response yet
Issues (all persist post-update):
Google Home 404 on Authorize
Reinstalled, cache cleared, mobile data, re-authorized — same “URL not found”
Groups & Scenes App
No gear, no Edit Mode, no Import dropdown (only Info → Settings)
ZEN77 Parameters
No gear, no Z-Wave Configuration section — cannot set Parameter 4/5 for 3–5 tap scenes
Working: Manual scene capture (Refresh + Update Scene), Room Lighting re-capture.
Tried: Reinstalls, console scripts, lockdown toggle, browser cache, mobile app — no change.
Request to Staff:
• Google Home token reset
• UI reset script or beta 2.4.4
• Z-Wave parameter workaround
Happy to test or provide logs. Thanks for any help!
(C-8 Pro, local IP, Android app)
If you open the Hubitat Dashboards app and click in, there is a "reset access token" button under Advanced. There is also one on each child dashboard under the main app (not sure if the main app one does all, or you have to click on it in each dashboard)
I'm not sure if that is related to your other issues, so hopefully someone from Hubitat support, like @bobbyD, picks this up, or maybe some other community member is more familiar with those issues in the apps.
Thanks for the great tip!
I found Reset Access Token under Apps → Hubitat Dashboard → Advanced, clicked it, and waited.
Unfortunately, Google Home 404 still persists after re-linking.
Appreciate the help — one more thing ruled out!
How long does it typically take to get a human response from Hubitat support. I submitted my request 9 calendar days ago and all I've gotten is an auto reply with a ticket number.
It greatly depends on the nature of inquiry. Usually 3 days or less. Regarding the Google 404 error, have you tried removing everything on both sides and starting over. We can't replicate on our end, so the problem might be on Google's side: Google home integration 404 error - #6 by nicksimoncelli
Thanks for your response. I had seen that thread and tried with no success. That is only one of a myriad of problems mainly UI related. Basically Hubitat is crippled and I'm having to use work-arounds to accomplish many things.
Bad choice of words on my part — I did not mean "the majority" have issues. I meant in my case, the UI is missing many elements that make it unusable on many functions for me.
Current State (2.4.3.156, C-8 Pro, MAC 34:E1:D1:82:1F:63)
23/40 devices live (16 ZEN77 + 7 MP31ZD) — all work perfectly
Dashboard:no Edit, no Import
Groups & Scenes: no gear, no Edit, no Import — only i in circle (info)
Google Home app completely missing from + Add built-in app — only "installation helper" shows
404 on authorize URL every time
I've been working for over a week trying numerous fixes, scripts, etc. but that would be too much info. As an example here is some detail on Google Home. What I've tried — Google Home (all failed multiple times)
Attempted to reinstall Hubitat Google Home app (only helper appears)
Remove/reinstall Hubitat Dashboard
Reset access token
Clear cache, private browser
Reboot hub
Restore downloaded apps (no built-ins)
Soft reset app data
Logs show nothing useful — just 404 on oauth
Support ticket #35024 merged — first reply received but no fix yet.
Question to community:
Has anyone seen Google Home vanish completely from the built-in list after migration?
Is there a remote metadata purge only support can do?
Thanks for the replies—appreciate the docs link and driver suggestion.
@bobbyD : I can navigate the GH instructions through step 7 (authorize in incognito, select devices), but hit the 404 error on the URL every time, even after troubleshooting (cache clear, multiple browsers, reboot, cloud backup test). The main issue is the "Google Home" app itself is missing from + Add built-in app—only "installation helper" shows. Any thoughts on that?
@jtp10181 : Thanks for the ZEN77 driver link—I'll try importing it via HPM. Is this to unlock the missing Z-Wave Config section (no params visible)? Confirming it's for multi-tap scenes, not GH/UI?
Full tried list in OP. Ticket #35024 open—hoping for remote fix.
At this time, we’re unable to provide remote support directly to individual local systems. As a local platform, we place a strong emphasis on customer privacy and security, so we do not have access to users’ local networks or devices. Because of this, we’re not able to remotely connect to diagnose issues.
That said, we’re absolutely here to help. If we can reproduce the issue in our testing environment, we’ll work to include a fix in an upcoming release. If we’re not able to replicate it, our options are more limited, but we’ll still try to do everything we can to walk you through some troubleshooting steps that hopefully can get things working for you.
If you are on your phone and getting the 404 on your phone via the google home app, that is going to be an issue with the app. Is this what is happening? (Unclear) What is the 404 Address?
For giggles, install Hubitat package manager, then install Google Home Community and see if that works for you.
404 happens on phone (Google Home app) when clicking Authorize after selecting devices.
Exact message: "404. That's an error. The requested URL was not found on this server. That's all we know. At the bottom of the screen it says: Error 404 (Not Found)!!1"
No PC authorize link — helper wizard stalls at Step 10 (no link)
HPM/Google Home Community:
HPM missing from + Add built-in app (same UI glitch as main Google Home)
