It’s 2021 and it’s still no decent way to control Homey for others than the owner I.e. guests etc.
What you would expect would be a solution similar to this one for Smartthings:
Not sure how many users there are out there using Homey today but it should be enough of a crowd so a developer would be interested in creating something.
And we don’t have to mention homeydash as a solution in this thread because it is already discussed elsewhere on this forum. I am trying to find something that is more similar to e.g. the SharpTools one.
