Trying to add a Boost (2019 version) to my existing system. I have cabled the boost but it can’t be found when I try to add it through the S2 app.

I have one existing speaker cabled - this is needed cause otherwise of of the speakers don’t connect. However, I don’t need a speaker close (and wired) to my router hence going for the Boost.

If I turn off my speakers the Boost is recognized by the app - but then I can’t add my existing setup.

Any idea what’s wrong?

Thanks, Lars
