Shelly 1 version 20230503-095514/v1.13.0-g9aed950 (latest)
Appliance Type: General
Button Type: Detached Switch
External Switch: Enable external switch add-on
Flipping the switch turns output ON/OFF
This was working on two switches, but stopped, not sure if after an update. I use the switch to use Home Assistant to turn on a fan light (but not the actual fan) using the light switch. If I just use the iOS app or look in Home Assistant, I don't see the state changing when I flip the switch, however I do see it in the Web Interface.
