Harmony Hub and IKEA Trådfri not working to 2.4

tandregbg · December 30, 2018, 8:26pm

I’ve just upgraded from 2.3 to 2.4 and after that IKEA trådfri AND Harmony Hub does not work. The Ikea trådfri “forgets” the security key after reboot - and the Harmony Hub are set to …177 IP adress (but under properties it says …8)

Hi
Harmony hub binding is not working any more if you have firmware 4.15.206
check the hub firmware version in de hamony app and read i.e.:

https://community.openhab.org/t/logitech-harmony-hub-binding-4-15-206-firmware-broke-local-api-connection/60090/101

I have no experience with IKEA

I hope this helps

The Trafri issue is known for a long time, but neither the cause nor a solution are known so far:

I created a bug report, as I am unfortunately no Java programmer:

[Tradfri] Connection gets lost on reboot of OpenHAB server

Binding-Trådfri

The issue described here https://github.com/eclipse/smarthome/pull/6193 was disc…ussed and a solution proposed. Still, it does not work reliably. There is a discussion in the OpenHAB forums here: https://community.openhab.org/t/tradfri-binding-loses-connection-after-power-failure-gateway-reboot/47833/61 ## Expected Behavior When the OpenHAB server boots, it should establish a contact to the Tradfri gateway. This connection should be stable. ## Current Behavior The connection is not reliably established after boot. One has to re-enter the credentials to get the binding online again. ## Possible Solution Try to re-establish the connection if it gets lost (and keep the credentials) ## Steps to Reproduce (for bugs) 1. Install the Tradfri binding 2. Enter credentials. Gateway comes online. 3. Wait. Reboot. Gateway does not come online at 2 out of 10 reboots. 4. Enter credentials again. Gateway comes online ## Context I run a Tradfri gateway to switch some bulbs. ## Your Environment * Version used: OpenHAB, milestone, currently 2.4 release * Raspberry Pi 3B+, running OpenHABian

Hi, I started experiencing key forgetnes for IKEA since I moved to docker. It was working fine before. Any progress with fix @micware ? Is there a way to configure it from files, so it will not forget values (if so, how)?

It is working now all by itself. I think similar thing happened last time.
I restarted server yesterday evening, and this morning Ikea didn’t work. Now I opened openhab and it is working. Also this morning remote access via myopenhab.org was not working so this might be related. Also my IKEA gateway has v6 IP [fe80:0:0:0:deef:czzz:fyyy:5xxx], while I am sure I wrote v4 in the binding, and I see ikea gateway on the network using v4 (but I am newbie to v6 so I might be blind here)
