It’s 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 it’s 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 ‘thing’ ( it’s 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 can’t 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=“xxx.xxx.xxx.xxx”, code=“xxxxxxxxxx” ] {
and the new config is:
Bridge tradfri:gateway:gwb07xxxxxxxx [ host=“xxx.xxx.xxx.xxx”, identity=“849xxxxxxxxxxxxxxxxxxxxx”, preSharedKey=“P2hjxxxxxxxxx” ] {
I also had to change all items that use this gateway as the UID has changed (from “tradfri:gateway:gw1” to “tradfri:gateway:gwb07xxxxxxxx”).
Remove the contents of your “tradfri.things” (or comment the lines in it, or move the file to somewhere else).
Restart openhab
After started, go into PaperUi to your inbox and accept the gateway.
Go to Configuration->Things and edit the Gateway, set the security code from the back of your gateway device.
Now OH talk to the gateway and recieve the identity.
Go edit the Gateway under Configuration->Things again.
Expand “Show more”, copy the value under Identity.
Go to your Tradfri.things and change it to look as:
Bridge tradfri:gateway:gw<your_gatewayMacAdr> [ host="", identity="<the identity value found in step 7>", preSharedKey="" ] {
Save the tradfri.things file, and then update your items to follow the new Bridge naming standard from step 8.
