It would be nice just to add and remove speakers from a group on the fly within a flow. I used to have rooms synched like this but now I can’t .
I do appreciate the workaround and shall use it… but if as Athom you own an integration and then make it closed source users do expect it to be as capable as the previous version … or to get, and hopefully address, this sort of issue.
I don’t like the closed source approach as really Athom are leveraging off many developers who offer their contributions ‘open source’ for free to help make Homey a better product.
