Fast Easy Setup and fully vustomizable

Over a year ago i built a dozen esp32boards with ld2410 mmwave sensors and AHT10 Temp and humidity sensors. This helped regulate the temperature based on room occupancy. When the Sat1 was announced with better temp/humidity sensors, Light sensors, ld2410 AND ld2450 capabilities along with voice,  I knew this was a major upgrade to my homemade sensors. I pre-ordered the board and when it came in set up was a breeze. Following the well written instructions on their website, assembly and flashing the board were as simple as could be. Within a few minutes I had a working “Jarvis” connected to Home Assistant. Writing a review for a product that simply works as intended can be pretty boring, but the Sat1 goes much, much deeper. Backed by a company that has put customer satisfaction above everything, their discord site is filled with highly knowledge and willingness to help personnel and enthusiasts. The official 3d printed case is sleek and easy to print and new designs are in the works. While I did print the official case, I opted to use my own design seen here simply because I wanted a front facing LD2410. This could have easily been accomplished with their case and a couple of wires but sometimes its just fun to do your own thing. Admittedly my design is far from the sleek, modern look of the official case but it still shows the beautiful design of the board and all its features. With help from the discord group, I was able to tweak my board with a “real” sounding “Jarvis” complete with attitude and humor to help pass the day. The Sat1 can be built with powerful speakers for great sounding music. I found the board so easy to set up that I plan to replace all my hand made sensors with Sat1’s to eventually bring voice control through my entire home. With a strong support team and extremely helpful discord group behind them the Sat1 is a great choice when bringing your home in the future. Thank you team for a great product and thank you to the discord group for making this a fun and functional project.

The beginning of a new Smart era!

Sat1 really has a LOT of potential! With NVIDIA and others announcing Home AI Hardware, as well as the Nexus box coming out from FutureProofHomes, Satellite1 becomes the first cloudless, mass-market potential add-on to Home Assistant (and whatever else you want to integrate it with). Everything is customizable, with a very decent built-in firmware, too, for those who want a product instead of a DevKit.

This board has opened so many doors for me to explore AI. It's great as is for AI / Smart Home enthusiasts, and a must for every room once stable!

Intitial setup and update of firmware

When I first setup the satellite is was without any issues. Home assistant picked it right up and once I found a external speaker I was off the the races. I then added one of the recommended internal speak I found the plug on the hat board very difficult to plug into. If the connector was facing outward it would have been very simple. I had issues when the update came out but it tuned out that I had multiple cables that did not support the data connection. Once I found one that worked the firmware update went very smoothly. Thanks to Brad for the excellent support. I did have to start-up my Windows 11 laptop to perform the firmware update as it seems that the update page did not work on my linux daily driver.I look forward to grow with the group and make the satellite my primary assistant. Keep up the great work.

WAF is high!

With Music assistant and a little node-red magic for notifications the wife is happy. I can finally ditch Alexa! Can't wait for that AI base station, so I can be fully local. I will be buying a few more of these for my new house and our Smart RV.
