Starting today my Tradfri gateway went to OFFLINE - COMMUNICATION_ERROR.
It was working perfectly for last two years and no changes were made on network nor configuration level recently.
The only thing I have noticed is that my tradfri gateway is updated to the latest version 1.8.25 which brings support for HomeKit and support for two switches on one bulb announced by Apple 7 days ago (11.04.2019).
It seams that for this reason binding is not working anymore.
Just for the record, I rebooted all devices multiple times and can ping everything.
Is this a known issue or should I look for some other reason? Does anyone else has similar issue?
Itâs a known isseu that after an update or restart of the tradfri hub the communication stop to Openhab.
For me it normally works to restart Openhab and when itâs started reboot the tradfri hub ( power on / off )
Hope this helps.
I block the auto update from Ikea, so will update tomorrow. A friend of mine had the same issue today and for him this restored the communication.
I just run the update. All seems to work for know. If I run into something will let it know.
After an update it also seems to work to disable / enable the tradfri gateway âthingâ ( itâs the clock on the right of the thing ) to get it back online. It took a few minutes.
I have all my Tradfri stuff in PaperUI, not in Things files.
I have tried quite a few different things, including removing and readding the gw from the inbox. But I have not been able to get it online after the Tradfri update
Hey, it just came online again, and all is working!
I think (?!?!) that what did it was:
delete the gw from PaperUI
restart OpenHAB
the gw should appear in the inbox, add it and enter the security code (for me the gw came online after a while but all the Tradfri unit did not come online)
restart OpenHAB again
be patient for 10-20 minutes, then all comes online
Good luck to you all
Got it working (after a fashion)
I canât get the gw to work if I set it manually in a.things file, but the detected gw works and all my items are back online
Thanks again for your help
I got it working.
You need to change the name of the gateway thing add the identity to the config file.
For me it was:
Bridge tradfri:gateway:gw1 [ host=âxxx.xxx.xxx.xxxâ, code=âxxxxxxxxxxâ ] {
and the new config is:
Bridge tradfri:gateway:gwb07xxxxxxxx [ host=âxxx.xxx.xxx.xxxâ, identity=â849xxxxxxxxxxxxxxxxxxxxxâ, preSharedKey=âP2hjxxxxxxxxxâ ] {
I also had to change all items that use this gateway as the UID has changed (from âtradfri:gateway:gw1â to âtradfri:gateway:gwb07xxxxxxxxâ).
