I have a similar problem. My Homey Bridge has been useless for 3 days now. In the Devices screen it shows a red exclamation mark. Tapping it results in a message in red: Homey Bridge Not Connected. Restarting it does not solve the problem. I reported the issue 3 days ago to Homey support, but I have not received any response, except for a confirmation message. I am deeply dissapointed in my purchase (just 1 month ago).
