Watering Settings

The grow-monitor-and-water.py example can monitor and, optionally, automatically water all three Grow channels.

It's configured using a settings file - water.yml - that looks like the following:

channel1:
        water_level: 0.8
        warn_level: 0.2
        pump_speed: 0.7
        pump_time: 0.7
        auto_water: False
        icon: icons/flat-4.png
channel2:
        water_level: 0.8
        warn_level: 0.2
        pump_speed: 0.7
        pump_time: 0.7
        auto_water: False
channel3:
        water_level: 0.8
        warn_level: 0.2
        pump_speed: 0.7
        pump_time: 0.7
        auto_water: False
general:
        alarm_enable: True
        alarm_interval: 1.0

By default auto-watering is disabled and an alarm will sound every 1s if the warn_level is reached.

Channel Settings

  • water_level - The level at which auto-watering should be triggered (soil saturation from 0.0 to 1.0)
  • warn_level - The level at which the alarm should be triggered (soil saturation from 0.0 to 1.0)
  • pump_speed - The speed at which the pump should be run (from 0.0 low speed to 1.0 full speed)
  • pump_time - The time that the pump should run for (in seconds)
  • auto_water - Whether to run the attached pump (True to auto-water, False for manual watering)
  • icon - Optional icon image for the channel, see the icons directory for images.

General Settings

  • alarm_enable - Whether to enable the alarm
  • alarm_interval - The interval at which the alarm should beep (in seconds)
