Recent update to Ikea Tradfri Gateway killed HA integration

I have just noticed that a recent update to the Ikea Tradfri Gateway has disrupted the HA integration with error during the startup.
I am also not able anymore to ping the Ikea gateway as i used to test it was running.

As anyone else came across with this new issue?

Ikea Gateway version 1.4.15
HA version tested 0.82.1 and 0.84.1

Error: Gateway


Translation Error: The intl string context variable ‘produttore’ was not provided to the string ‘da {produttore}’

Translation Error: The intl string context variable ‘versione’ was not provided to the string ‘Firmware: {versione}’


Maybe your Gateway now has another IP-Address, because it was not fixed on the router?
Do you see the gateway in the routers network list?

Hi, I am using static IP addresses.
After a couple of gateway restarts I can now ping it, but the issue persist.
This is the log:

Hmmmh, i’m running the same Gateway version

Type: E1526
Firmware: 1.4.15

  • 2 Bulbs (at the moment)

and HassIO: 0.84.1 (updated from 0.81.2 today)

No problems so far…
btw. I installed Tradfri using “discovery” on HassIO (one week ago on 0.81.2)
Since i’m a beginner, i hope some more experienced users can help you…, e.g. how to delete the old integration and start a new one?

Hi, everything is back to normal, I don’t know what happened…
Regarding your question, Tradfri configuration is stored in a hidden file in your config folder.
One is called .tradfri_psk.config.
A reference to Tradri is in .storage/core.config_entries and in core.device_registry and core.entity_registry you’ll find the discovered bulbs/devices.

To start a new integration just delete them all.

I’m quite a noob in these matters, so forgive me for asking dumb questions.
I’m running Home Assistant on a raspberry pi 3 b+ and using the “auto discovery” in HA. It discovers the IKEA Trådfri GW, but when I submit the security code the GW re-boot and HA’s getting timeout validating the code. The GW has a fixed IP in my router, and it is working with bulbs and remotes “outside” HA.
Any idea what’s the problem?
In core.entity_registry there is not a trace of any IKEA products either.
