Build the Satellite1 Together
Yesterday I only received an Encloser Kit without the Dev Kit. The new Encloser Kit also has a bass tube and a hole in the enclosure, which the first shipment two months ago didn't have. Now, what am I supposed to do with just the enclosure and speakers without the Dev 1.1 Kit? Furthermore, I can't find anywhere to order just the enclosure with speakers. What went wrong? Note: Only one unit is shipped to Europe, hence this second order.
Hi Peter, feel free and ping us at support@futureproofhomes.net, but you can purchase the fully assembled speaker, or the individual “enclosure kit”, “electronics kit”, “PCB dev kit”. Sorry for any confusion these choices may have caused. You can also chat us from discord.FutureProofHomes.net
Easy to config, sounds wonderful, and looks impresive.
Thanks for the design.
Very nice product
Great sound a quality overall
On my conference call to discuss the issues I agreed to investigate the performance and speech capture issues. The test compared V1.4 with HA Voice PE and the latter won hands down. (a total of 30 repeated tests at 1/2/3 metre distances per device).
I asked for a refund but luckily V1.5 arrived just in the nick of time. The voice capture was not distorted but instead now fully captured (not cut or parts missing). And the wake word activation more sensitive / reliable, but still not quite as good as the HA Voice PE which responds 4 metres away in another room when standing by the Sat1. I was advised that wake word training might be needed due to having a British acent and that’s on my todoist list.
This product has promise and wish the development team good luck with further improvements
