At times when I open the app either from home or work, I get the message “no response from hub” and when I tell Google to turn a light on or off, Google Assistant says “It looks like the Hubitat is unavailable right now”. I have a ST hub right next to the Hubitat hub and have no issues controlling what is connected to that (IKEA shades which their remote is not supported, so to keep the WAF high, these shades have not been moved to Hubitat)
After a few minutes, both the app and voice commands work fine. It just started working a few minutes ago and now it is not responding.
I struggled with this issue for weeks and contacted Hubitat support about it. I was trying to figure out if I could live with it or not, when I finally noticed that I had a vlan subnet overlapping the local subnet my fiber modem was handing out to my local router. So there was literally two paths that incoming packets could take. I overhauled my entire network when I migrated to habitat, and I made an error I just never discovered. So I don't know what your network setup is like, but if it isn't super simple, then I would double check everything.
Also, I had LOTS and LOTS of zigbee/zwave trouble while running smartthings and hubitat at the same time. My hubs were right next to each other also. Once I got everything moved over to hubitat and shutdown the smartthings hub, all of my mesh issues went away. I know many are running this scenarios successfully, but that was my experience.
@scottie.holden Thanks for the informative reply. I only have one router and one cable modem, but the ST hub is right next to the ST hub for convenience. No issues noted with ZigBee or Z-Wave devices.
Something else I noticed - the IP of the HE hub toggles between .114 and .115, so when I open the app, I can’t see any dashboards until i run hub discovery. Just tried to turn on a bulb with GH and got the message it couldn’t connect to the Hubitat. Opening the app, all dashboards are there and the devices respond. When another GH command was sent, the light turned on.
@bobbles When I was using Amcrest cameras for my home security I could specify their static IP in their app and never had to set it in the router. I will investigate that. Thanks. If the IP changes, I would assume that is why GH can’t talk to it.
Will report back once I have time to try and not breaking what works.
Most people reserve the address of their hub on their router so that whatever happens, power cut etc., the router will always assign the same address to the HE hub.
been getting this a lot lately, myself. I just keep trying until I get a response, but the amount of effort required each time to succeed seems to be random, as does when it happens.
Hmm. My router is a Tenda AC15 AC1900 model. I drilled into each menu to see if there was a way to reserve an IP. The Tenda website says the DHCP/static IP setting is on the Main Menu but it isn’t there. Sent an email and waiting for a reply.
So I got the No response message last night and this is what I saw on my HUB free memory. Like clockwork for the past couple of weeks. A hub reboot is needed every 3-4 days.
