SnakeHome is a local-hosted powerful Snake-Styled automation system, based on HAOS and using wireless relays and some sensors. Hosted on a Raspi 4 and directly driving I2C sensors and Digital sensors, using the Raspi's GPIO.
I like that I can automate and smartly control my whole house, and also using my voice to control it. So, decided to make this project as i can host, control, automate, and integerate many things..
- Snake-Styled Case
- Using I2C bus on the same Pi 4
- Has additional I2C buses using an I2C multiplexer
- Custom Pi Hat for the I2C buses, RGB strip, and Motion sensors.
