Netatmo integration, error in log every 30 seconds

Hi, after fixing Netatmo Event filter on camera_id I now have an error message in the “Core” log every 30 seconds. Or maybe that message was already present earlier, I am not sure. From a functional perspective the Netatmo integration works well, so it looks like nothing goes wrong. But to log an error every 30 seconds does not feel right. The message is:

I run Home Assistant 0.113.3, HassOS 4.11. I would rather not upgrade since everything (Tasmota lamps, Zwave sensors, Netatmo) runs fine, I would prefer a specific fix or workaround.
Does anybody have a suggestion … thanks!

Hmm, this problem comes and goes. This morning it started again to log every 30 seconds … not wanting to wait for some unknow trigger that will cure this state I restarted HA … Any suggestions are appreciated!
