Problem with Homekit, Devices not responding after a few hours

[BremerButjer (Matthias Schwarzer)]

After I was able to reconnect the Homekit by using the ClearCache command and removing the ColorTemperature item, now a few hours later all connections flew away again. (Devices do not respond).
I have read some, older, posts but no correct solution found.

Does anyone have a idea?

You can try to disable the private wifi address on your iOS device for the wifi network you use. Worked for me to make the home app more stable and responsive.

Are you using Unifi equipment for Wifi?

Below is a quote I left on the " Homekit bridge to OH3 lost" Topic. It could explain what is happening. I don’t think a fix has been pushed out yet so I believe this issue is still active.

@Prillin

I just struggled with something like this myself. What I have found is that the act of “Saving” the Homekit Add-on inside the OpenHab3 UI causes some of the data to be lost when the config file is over written. Specifically the entires pertaining to MAC address and User Identifications. I would set up the binding with the suggestions above (Remove, clearPairings, Re-Add Bridge to HomeKit etc…) and still find my devices non-responsive after a while. Finally I figured out that the data was being lost when I was saving to make changes like such as to enable the use of mDNS. So I examined the config file and confirmed the discovery, I then after going through the process again to get it all set up correct then simply duplicated the config file just incase I clicked the save button again and lost all the specific data for users, If I did I can now replace with a good copy again and not lose the connection to my devices. I have at this point started to only modify the config file manually - it does require OpenHab3 rebooted to see the effects take place but I don’t lose my devices. I have now been running stable for approximately 5 days and everything is stable and works. I no longer get told by Siri that she can’t communicate with my OpenHab3 Devices.

I have avoided editing the configure file and saving it via OpenHab3 UI for nearly 30 days now and I have not lost my Hub or seen unresponsive items in Home App due to the lost Hub.

Just as a note, I have not made any changes to the private wifi address setting. my iPhone is currently running the latest iOS 14.6.

Hopefully this resolves your issues too.

Hi Prilin,
could you explain what configuration file you have backed up?
@dirkdirk : No improvement by switching off private wifi address
@dennisvonderbey: No Unifi equipment (AVM FritzBox)

The specific file that was losing data for me, the one I backed up and replaced if I lost the host is located at: (Im running this on MacOS)

“openHAB application”/userdata/jsondb/homekit.json
