Home automation with zigbee
Architecture
In this project I would like to share my experience in how to control my home by mainly one digital cube and alternative with some wireless switches.
As well as using different zigbee sensors and actuators to monitor and control my home.
This project uses the ‘Aqara Cube’ as an interface to detect control requests. The Aqara cube can detect motions such as push, flip 90°, flip 180°, rotate and tap.
Furthermore the wireless switches are used to set the controlled devices in a previous defined state. This is used to imitate real live situation for example leaving the house and turn off all devices.
To receive the control messages from the cube this projects used the USB zigbee module ‘CC2531’. Furthermore to interpret the signals I used ‘zigbee2mqtt’ and ‘Eclipse Mosquitto’ as a message broker.
