Build the Satellite1 Together
So Ordered this a few months ago. Waited a while before putting it together as unfortunately don't have a 3d printer for the case and my friends 3d printer is not the best. But that being said, put it together(board, add on board, and speaker a little over a month ) ago it went together nicely the directions were very good. paired with home assistant quite well. The sound is good the voice pick up is quite okay along the lines of most. But I believe that will improve with some firmware upgrades I have been reading about. The voice assistant capability works not as well but that isn't a hardware issue. Very impressed with the hardware. I have gotten it to work acceptably well using a local LLM although as with all things there are caveats. I have since ordered another one with their new case option and am greatly looking forward to see this go further in the future. I have high hopes for Nexus although with the computer industry having its issues at this time and the near future I can only guess that will possibly delay some things. But, the main takeaway from this is that this is a good product and the copany has done so far exceptional good on their design.
Commenting on the Core Board And Satellite1 module together - I did not use them apart. I found the integration into Home Assistant to be very straightforward while using the instructions on the web site under support. Excited to put this to full use.
Great product, I'm satisfied
Once I set it to Aggressive for finished speaking detection, this has worked very well even with a TV on in the same room. I'm looking forward to permanent mounting on my ceiling and getting more if it works well.
Surrounding Noise is Not canceled. I have to mute the Radio / before talking to the Satellit
