Go MarsHydro LightControl

This project controls the brightness of a MarsHydro lamp based on a timer configuration. The application reads configuration files for timing and account credentials, calculates the expected brightness based on the time of day, and updates the lamp accordingly.

Project Structure

• main.go: Initializes configurations, computes light timings, and runs the control loop.
• internal/timer/timer.go: Contains the logic for calculating expected brightness.
• internal/config/config.go: Handles loading configurations.
• internal/api/mh_api.go: Manages communications with the MarsHydro API.
• timer.json: Timer configuration file.
• account.json: Account configuration file.

Configuration Setup

Timer Configuration (timer.json)

Create or modify the file at:

/Go_MarsHydro_LightControl/timer.json

Example configuration:

{
  "StartHour": 8,
  "PlateauHour": 6,
  "PlateauOffset": -1,
  "Brightness": 100,
  "EndHour": 20,
  "StepSize": 10
}

• StartHour: Hour when the lamp starts to turn on.
• PlateauHour: Duration (in hours) during which the lamp remains at its maximum brightness.
• PlateauOffset: Offset (in hours) to adjust the sunrise/sunset ramp durations.
• Brightness: Maximum brightness during the plateau phase (i.e. the highest sun state).
• EndHour: Hour when the lamp turns off.
• StepSize: Brightness step increments (must be a multiple of 5).

Account Configuration (account.json)

Create or modify the file at:

/Go_MarsHydro_LightControl/account.json

Example configuration:

{
    "Email": "email@provider.example",    
    "Password": "PasswordHere1234",
    "Wifiname": "Wifi1234", // Note: the Wi-Fi name is only used to make the API request seem legit. Providing your real Wi-Fi name is optional.
    "Timezone": "Europe/Berlin", 
    "Language": "German"
}
