IKEA Tradfri gateway + Domoticz AND Home Assistant

Hi

I have

  • IKEA Tradfri gateway
  • DOMOTICZ v4.10717 with IKEA Tradfri Plugin - version 0.7.3
  • HOME ASSISTANT (hassio in docker) v0.104.3, with IKEA Tradfri integration

I noticed that I can NOT connect both addons to my IKEA hub.
It works… sometimes, but I have the feeling that the Domoticz plugin “locks” the connection so that hassio can not control my devices anymore.

Hass.io is responsive and shows changes in status immediatly.
But if I enable the Domoticz Tradfri plugin in domoticz, things are working well for a short while. After that, hass.io doesn’t show any status changes.

In domoticz, I tried the different options for “observe changes” in the plugin settings, but no solution.

Does anybody has the same experience?
Is this a bug?

Kind regards,
Bart
