Smart Watering for Farmbot

With the PowerLoop and Water Doser farmware installed, you can water each plant precisely.

Check your Farmbot configurations

Make sure your Farmbot configurations are correct:

• check camera calibration offset x and y,
• Photos must align when enabled from the farm designer by toggling "Photos" on the right side. To take photos of entire planted area, use PowerLoops with grid_coverage_overlap set to 0. See Automatic Farmbot Garden Selfie example
• The way to check is to move the Farmbot to the plant location and drop the z axis to plant level and see if the center of the UMT aligns with the center of the plant.

Steps to configure

1. Install "PowerLoop" AND "Water Doser" farmwares.

2. Create new sequence Run Water Doser to execute Farmware Water Doser with the default parameters. Fig. SWD: Water Dose Sequence with water-doser farmware

   Hint: If you wish to use your own timed watering sequence, skip this step.

3. Create new sequence Water all plants with:

• Execute Sequence: Pick up watering tool (your own sequence)
• Excute Farmware PowerLoop:
  • Sequences After Move (created in previous step): Run Water Doser
  • Filter by plant name: *
  • Filter by OpenFarm slug name: *
  • Filter by meta data key: last_watering_at
  • Filter by meta data operator: minutesmin
  • Filter by meta data value (2 hours min passed): 120
  • Save in meta data key: last_watering_at
  • Save in meta data value: #now#
  • Debug mode: 1
• Execute Sequence: Return watering tool (your own sequence)

4. Test it by saving, and clicking "Test".

Expected outcome:

Each plant visited in an optimized route, Water Doser is run for each plant and opens water valve the calculated amount. The meta key 'last_water_at' is set for each plant to avoid excessive watering in case of errors.
