Another great Smart Home Assistant we came across the other day is Gladys. Gladys is an open-source program which runs on Rasberry Pi. It has a very enthusiastic community which is around 28k big.
The video gives you a pretty good idea of how it works. It’s mainly created to support across the day and works a lot with motion sensors.
The best thing about Gladys is that it is completely free, the only thing you need is a Raspberry Pi. Check out the website here.
