😊 CLIENT

It was It was a training project at the course Creating Web Services on Django Coursera.

✔️ CHALLENGE

My task was to implement a smart home management server on Django, which has a web-interface for configuration and manual control, which will perform periodic sensor polling and automatic response in case of certain situations, using the smart home controller API.

💻 SOLUTION

Reaction to events:

If there is a water leak (leak_detector=true), close the cold (cold_water=false) and hot (hot_water=false) water and send a message when detected.
If cold_water is closed, turn off the boiler and the washing machine (washing_machine) immediately and under no circumstances turn them on until the cold water is opened again.
If the hot water temperature (boiler_temperature) is less than hot_water_target_temperature - 10%, the boiler has to be switched on and wait until it reaches hot_water_target_temperature + 10%, after which the boiler has to be switched off to save energy.
If curtains are partially open (curtains == "slightly_open"), they are on manual control - this means that their state cannot be changed automatically under any conditions.
If it is darker than 50 outside (outdoor_light), open the curtains, but only if the lamp in the bedroom_light is not lit. If outdoor_light is lighter than 50 or if the light in the bedroom_light is on, close the curtains. Except when the curtains are manually operated.
If smoke_detector is detected, immediately turn off the following devices [air_conditioner, bedroom_light, bathroom_light, boiler, washing_machine] and under no circumstances turn them on until the smoke disappears.
If the temperature in the bedroom (bedroom_temperature) rises above bedroom_target_temperature + 10%, turn on the air conditioner (air_conditioner) and wait until the temperature drops below bedroom_target_temperature - 10% and then turn off the air conditioner.

The project was implemented on Python (Django), PostgreSQL. I used Docker Compose to deploy VPS.
