Here are the debug logs of the two devices: config_entry-shelly-4daf1300fdc14430e3eb09e9dc21e204.json.txt config_entry-shelly-b3e34301f8e966327dd71583eb87616d.json (1).txt

I don’t know if it also inspects Wi-FI-2-LAN traffic. I think I can’t add a rule on my firewall, no option for it…

But its interesting: yesterday, I had to switch my router off for 10minutes and then restart it. Since, no error anymore on my two shelly devices !
