Please read Welcome to the forum to get started.
one question I didn't found an answer by the search function.
I am converting my smart home System from ZipaBox to Homey and did so far 70% of the way. Still some key devices are not supported by Homey, but this is a different Topic.
At ZipaBox I have the Option to add a battery as well as a GSM stick (security module) in case of the power breaks down and/or the Internet Connection.
Just having an eye on the power problem: Has someone solved this issue by using a power bank between the plug and Homey?
