GrowBuddy v1.0
GrowBuddy v1.0 is intended to help you automate growing your plants indoor.
It takes care of :
- growlight automation
- automated watering
- circular air
- ventilation
Requirements:
- JSScripting (ECMA2021) enabled for the additional Rule which interacts with the widget (or you can write your own rule in your preferred Rule-language)
- Additional items for storing several values (startTime, endTime, wateringInterval, wateringDuration, growPhase etc…)
- Four Smartplugs for the devices you want to control (growlight, circular-air, air-ventilation, watering-pump)
…and of course the physical equipment to connect it to your Smartplugs ;)…
After following this guide…
you should be able to relax and enjoy your automated grow experience, the widget takes care of enabling and disabling your GrowLight - you only have to adjust your desired StartTime and the widget automatically chooses the EndTime according to the selected GrowPhase (18 hours for Grow and 12 hours for Flowering period). You can choose a WateringInterval between 5 minutes and 1 day in certain steps and a WateringDuration between 5 and 90 seconds. The AirCirculation automatically starts with the GrowLight and stops when it turns off, the Ventilation runs 24/7 except the MainSwitch is turned off, which automatically disables all Smartplugs. You Only have to take care of your WaterReservoir ;)…
The Rules File (ECMA2021)

The Items
You need to create the following items with the exact names and item-types:
- SmartplugGrowlight (itemType: Switch)
- SmartplugVentilation (itemType: Switch)
- SmartplugCirculation (itemType: Switch)
- SmartplugWatering (itemType: Switch)
- GrowbuddyMainSwitch (itemType: Switch)
- GrowbuddyGrowPhase (itemType: Number:Time)
- GrowbuddyWaterInterval (itemType: Number:Time)
- GrowbuddyWaterDuration (itemType: Number:Time)
- GrowbuddyWatering (itemType: DateTime)
- GrowbuddyLightStart (itemType: DateTime)
- GrowbuddyLightStop (itemType: DateTime)
If you’re too lazy to add this items by hand, you can import the growbuddy.items to your MainUI or textual config. To import to Main UI navigate to the items section click on the + sign to add an item and choose “Add Item from Textual Definition” and paste the following code.
Switch SmartplugGrowlight "Grow Light" <switch>
Switch SmartplugVentilation "Air Ventilation" <switch>
Switch SmartplugCirculation "Air Circulation" <switch>
Switch SmartplugWatering "Watering Pump" <switch>
Switch GrowbuddyMainSwitch "Main Switch" <switch>
Number:Time GrowbuddyGrowPhase "Grow Phase Selector" <time>
Number:Time GrowbuddyWaterInterval "Watering Interval" <time>
Number:Time GrowbuddyWaterDuration "Watering Duration" <time>
DateTime GrowbuddyWatering "Watering Time" <time>
DateTime GrowbuddyLightStart "Grow Light Start Time" <time>
DateTime GrowbuddyLightStop "Grow Light Stop Time" <time>
Script to initialize DateTime Items (you only need that once)
add this script in MainUI in the scripts section (choose ECMA2021) and execute it.
let now = time.ZonedDateTime.now();
items.getItem("GrowbuddyLightStart").sendCommand(now.minus(time.Duration.ofHours(4)));
items.getItem("GrowbuddyLightStop").sendCommand(now.plus(time.Duration.ofHours(8)));
items.getItem("GrowbuddyWatering").sendCommand(now.plus(time.Duration.ofMinutes(1)));
