This middle complexity house control smart assistant based on the raspberry. It supports interface over web, telegram messenger, voice It alerting over telegram messenger, mail, voice. Because I got 2 raspberry one at the house and one at the flat - there are 2 configs.

sensors :
- DHT22 - for temperature and humidity (actually I can read temperature from CO2 sensor)
- MH-Z19 - CO2 sensor
- PMS7003 - particles sensor
- light - standard raspberry light sensor
- moisture - standard raspberry moisture sensor
- waterlevel - standard respberry waterdrop sensor
devices:
- raspberry camera/ USB camera
- outlet 220V - general purpoise
- IR transceiver for control conditioner
- Fan on the heater to increase temperature in the room if needed (12V)
- plant watering engine (5V)
- WOL wake up pc over telegram
for voice control:
- USB connected jabra speaker - it got good noise reduction for task
for display:
- nextion display on uart for display current values
