Build the Satellite1 Together
Easy to set up. Very responsive. Great audio sound. Background noise filtering seems excellent. Added to Home Assistant in less than a minute. Board doesn't get hot in normal use suggesting good electrical engineering. So impressed I've ordered 2 more for other rooms. PLEASE start selling the cases ASAP!!!
This whole project is absolut amazing. The Hardware ist first class, the documentation ist very detailed and the 3D print files fitted perfectly. Overall really great job.
At now, I am not very comfortable with the voice assistant from Home Assistant, but this has nothing to do, with this project.
This device works well and has the expandability that all us tinkerers enjoy. It installs fairly easily, although I am trying to flash and reinstall one that recently just stopped work on me with no success as of yet. I think this may be the best voice assistant yet and I am looking forward to the cases, speakers and other offerings to enhance it's functionality. Mike Cat
Easy to install and setup. Printed large enclosure, may buy another and try the medium enclosure
I added the Dayton,RS75-4 speaker and printed the cylindrical housing. All went well and looks and perform very well. I liked it so much that I ordered another one.
