Disabling cloud client as Invalid password at connection
What issue do you have? Please be as thorough and explicit as possible.
Just following on from the previous update v7.10.1, all of a sudden I have for the last two days had the connected devices still visible in HomeKit, but not working. See logs below. Seems like a cloud connection issue? I hadn't made any changes or updates for several weeks until today when I updated the plugin to 7.10.1. Error occurred while running 7.10.0 and 1.10.1. Using the recommendation Hybrid Control connection type.
