My issue was with the broadcast ip address, had to change it to the server IP address. All my issues are resolved.
sorry but did not understand a word from “broadcast ip address”. What is that? Wo is that?
In the shelly settings you have the CoIoT peer field where you can fill in an IP address.
By default it’s a broadcast IP but if you change that to the HA IP it fixed my issue.
Could you share an exemple of what you made?
