I'm new to the hubitat and smart hub game and recently purchased a c8 to start my system. I installed and set up the hub and have connected a smart 32 amp switch to it via z-wave. It works fine for a little bit and then the hub seems to disconnect from the wifi network as I can't access it via the mobile app or the web portal after a short amount of time (an hour or so). If I disconnect the power to the c8 and restart the hub it boots and connect to the wifi and everything works for a short amount of time before the same problem arises.
I was wondering if I should do a factory reset on the hub and start everything from scratch with the hub connected via ethernet on the modem/router rather than wifi (I have actually tried connecting the hub directly to the router but it won''t work at all and I assume it needs to reset to do this). Or do I simply need to change any of the settings on the hub or the network - Override DNS settings or change a configuration on my router or....?
My Hub's Hardware Version Rev C-8 with an IP address is 192.168.0.195 (WiFi - Boogie) via DHCP . Running Platform Version 2.3.5.131
Some help would be appreciated as I am seemingly down a rabbit hole here trying to make this work. And I thought the hubitat user experience would be much easier than I have encountered.
Hold button for 7+ seconds, let go, LED will blink and hub will reboot. It will be back on DHCP.
Not totally sure if it will clear the Wifi settings or not, but you can disconnect the Wifi from within the UI in settings as well.
I would also say hard wired is the better way to go. If you can't though what is your wifi router hardware make/model? Also are you using Jumbo Frames anywhere?
Thanks for your help. I have disconnected the wifi via the UI in settings and cleared the network settings and restarted the hub with it hardwired connected via the ethernet. Heres hoping that clears up the issue and the hub stays connected on the network now.
I was looking through the bug logs and it seems to be a "token refresh fail" issue or a "refresh token is not valid" issue that keeps cropping up
Got the same issue. Hubitat C8 was setup first with Ethernet cable but moved it in other room now on WiFi. (Newbie of Hubitat 2 weeks) Did yesterday firmware update but today already lost again the connection to router (ASUS DSL-A82U).
Only have to unplug Hubitat C8 for 5 seconds and is connecting again.
I was reading yesterday you are working on it but the Firmware update from yesterday did not fix it.
Moved from a SONOFF hub to Hubitat because SONOFF hub just deleted some zigbee device and dropped connection to device as well.
Now Hubitat has great connection to devices and keep them stored but doesn't like to work more than 24 hours.
I am crossing my fingers for a sooner fix.
And a reminder to those new to the HE game, there should be limited times where you need to unplug the power. Doing so can lead to corruption of the database, which is also recoverable, but not a necessary side-effect of situations where you can avoid pulling the plug.
My experience was as soon as I went to ethernet, after totally clearing the wifi settings, all issues were resolved. Works perfectly now and doesn't drop out. Seems like it's not totally built for perfect wifi use as yet.
While it's great to hear your setup is working much more reliably now, and a wired connection is always recommended for a number of reasons (unrelated to HE's implementation of Wi-Fi), I still think it is a little unfair to label the HE Wi-Fi connectivity as being at fault without having fully diagnosed the reasons for your issue, at least based on the comments throughout this thread.
What exactly is happening after you reboot the HE hub? Do you have any sort of connection to the hub, either through a browser on a PC/laptop/Mac, or through the HE App on a mobile device? If you access your router web interface can you see the HE hub as a connected device? Do you happen to have automatic blocking for new devices in your router (like I do)?
If I go to my router I can see it is disconnected. My only way is in the moment unplug for 5 sec and we are back on.
If I didn't notice for a long while the zigbee devices will take awhile to connect again.
I am also seeing my C8 Hub frequently disconnecting from my WiFi network.
The C8 disconnected a couple of weeks ago, but I didn't realize it was disconnected until we started to notice that our device automations stopped working.
The C8 appears to be disconnecting every 24 hours or so. I unplug the C8 daily for about 30 seconds and plug back in to reboot and reconnect.
I just updated to the latest platform (v2.3.7.145) a couple of days ago when I started to investigate what was going on.
I too have a C8 on WiFi (no cable at the site, so ETH is not an option), yet it disconnects almost every day.
Now running the 2.3.8.128, but it is extremely annoying.
I've set the IP as fixed in my router (Ubiquiti UDM SE)
The hub is only collecting data from a few zigbee sensors, no heavy automations, no errors in logs...
Can I ask someone to access the engineering logs if they can found something wrong? Maybe some WiFi setting? Since I bought this hub specifically because of the WiFi, I'm not able to use it properly
If your Wifi has "Optimization" enabled, try turning that off. I think Ubiquiti was the one that has this setting. People found it was changing the channel in the middle of the night and causing the hub to disconnect.
