Smarthome KNX Knowledge - Gira X1 with Alexa and Sonos - Please provide feedback

Yes, but that is more the DIY department... Not that it doesn't have its niche (is also used by us).

Oh man. I was already quite impressed that the X1 was supposed to support Sonos, but then I have to read that the update won't come until October. So with Gira, that means Christmas.

I got the Hager IOT for this, but I'm not very happy with it yet, it offers too few KOs.
Changing favorites is not so easy (each favorite is addressed with a separate GA), the status of the speaker is output via a 14-byte data point. On/Off would have been enough to provide a button with the necessary status. Instead, "Playing/Stopped" is output.

Tomorrow in 9 months is Christmas... that’s doable

Since we’re only starting to build next year... that’s still early enough for me... who knows what else will come by then

...who knows what else will come by then

That is the right attitude... and precisely not to fixate on brand names. Everything that has the KNX logo can be installed.
