HA loses connection to IKEA devices every other day

Hello all,

I’m facing a problem with my HomeAssistant setup that I can not solve.

Home Assistant hardware setup:

  • Running on a Raspberry Pi 4, 4GB
  • HA Core2024.12.4 / Supervisor2024.12.0 / Operating System14.0 / Frontend20241127.8
  • IKEA Tradfri hub, software version 1.21.31
  • AEON Labs, Z‐Stick Gen5 USB Controller
  • RFXCOM, RFXtrx433E, USB 433.92MHz Transceiver
  • 44 IKEA devices. (39 lamps and outlets, 2 signal repeaters, 3 speakers)

I use HA for switching my IKEA lights. Every other day my lamps and switches become unavailable / unresponsive in Home Assistant. I can still access them with the IKEA Home smart 1 app. There are no errors in the HA logs.

Solution to get the IKEA devices active again is rebooting Home Assistant. Don’t think this is a sustainable solution as other family members don’t know how to to this.
I’ve searched the forum but haven’t found a solution for the problem.

Has somebody seen this before and found a solution for it?

Thanks in advance,
Paskal
