Mine is still broken :frowning: I have to reboot the gateway to get it back online, however it does come back online in openhab without me doing anything.

125

Iā€™ve had this issue for months (april?), but no time to do any troubleshooting. Is it possible to only update the binding to solve this? Iā€™d like to run 2.4 until 2.5 is releasedā€¦

126

Iā€™ll answer my own question in case someone else has the same issue. My Tradfri gateway came online after updating to the latest binding.

Following the guide here

using this address to get the binding

On M4 it started acting up again :roll_eyes:

128

For me the gateway only came online when I disconnected the gateway from the Ikea Home Smart App.
Took me a long time to figure this out, hadnā€™t read it on any forum yet.

I canā€™t get this to work anymore. Thing always says ā€œStatus: OFFLINE - COMMUNICATION_ERROR Error connecting to gateway.ā€

I already removed the thing (paperui), clean-cache, restart, reboot, gateway reset to factory defaults, removed/reinstalled binding, nothing helps

Iā€™m on OH2.5, gateway is 1.9.27

Any idea?

Never mind guys, problem solved

131

May I ask how you solved it?
Thanks, Dietmar

PEBCAK issue :rofl:

I was using the serial number instead of the security code, took me 12h to discoverā€¦

133

Well,

seems it not solved completely afterall.

Every couple hours my gateway goes offline and can not even connect anymore with the ikea app.
All I need to do is power cycle the gateway, restart the binding and then it works for a couple hours.

Do I have a malfunctioning gateway?

When this happened to me after they pushed a new gateway FW, I had to reset the gateway with a pin and re-include everything. Thatā€™s when I said never again and ditched that gateway in favor of conBee/deCONZ. It can even upgrade device firmware. More.

It happens every couple hours, and this is what i noticed in the log:

[WARN ] [discovery.TradfriDiscoveryParticipant] - Discovered Tradfri gateway doesn't have an IP 
address: [ServiceInfoImpl@1798094391 name: 'gw-44916030ff2d._coap._udp.local.' address: 
'(null):5684' status: 'NO DNS state: probing 1 task: null', has NO data, empty]

Although it is defined in the things file:

Bridge tradfri:gateway:ikea [ host="10.0.10.202", code="**************" ]

Any idea?

In the meantime i order a usb zigbee stick to move to zigbee2mqtt in the hope this solves this crap.
