ShellyPro4PM constantly loses connection


I have recently integrated several Shelly modules via the official binding. For two ShellyPro4PM, the IP address set in the Thing configuration changes from 192.168.x.x to [fe80:0:0:0:eb8:x:x:x] after a certain time and thus loses the connection to the module.

I have tried the following

  • Restarting the module
  • with and without password for the module (Thing was recreated after changes
  • UpdateoH from 4.0.3 to 4.0.4
  • Update Shelly modules to the latest beta version
  • Set static IP address in the module

I need help!
