Every time I restart HA it discovers a new Shelly switch with IP address. I press “Configure” on Integration panel, “Do you want to setup?” - “Submit”… it works for a while and then reports “Failed to connect”… That is it. I cannot add it anyhow… the shelly works via MQTT, I do not need this integration but it discovers the device every time…
I had the same issue with the Door/Window 2. I updated the Shelly firmware, now it works! It should be 1.8.x or higehr!
Ohh,mine is 1.7 . I thought it is quite fresh for integration. Thanks!
