I am still working the integration and have completed all but the TTS integration. TTS issue is I can not find the command to invoke the URL play for the speakers. Once I find that (and I continue to search), then TTS will be enabled. There is a work-around to be able to use this product and have TTS capability on the Speakers - I will explain this in the other thread sometime this week. So far, it is relatively complete except TTS:
a. Full control of speaker functionality (including source toggle, repeat, shuffle, equalizer mode select.
b. Eight CP presets (some limitations) - set up in Multiroom app, then set in dh.
c. Three (per speaker) group presets - set up in Multiroom app, then set in dh.
