Plantwatery but with ESPHome (based on ESPlanty)

Hardware

• ESP32 WSROOM
• Capacity Soil Moisture Sensor(2 slots available)
• 1 Channel 5V Relay Board
• MCP1700 3.3v Voltage Regulator
• 5V 1.2W (at least 0.5W) Solar Panel
• 5V 2.4W Decdeal Water Pump
• Pneumatic Tube 6mm
• Pneumatic Tube T Connector 6mm outer diameter
• Pneumatic Tube End Connector 6mm outer diameter
• Slide Switch
• Water Canister (e.g. Plastic Box 12 litres)
• M3 (4-9mm long) Screws for mounting

Note: My Hardware setup in theory allows to connect 2 moisture sensors and 2 water pumps, but only 1 each is used as of now.

Software

Requirements

• Home Assistant
• ESPHome integration
• Create Input Boolean Helper integration with id input_boolean.ota_update_available

Code

plant_watering_control.yaml:

1. Checks if there are OTA Updates available (toggle in HA), if there are updates, prevent deep sleep
2. Reset sensors and take measurements (median with sliding window, notification with sensor values)
3. Start watering if moisture is below threshold (notification for water pump start and stop action)
4. Re-measure moisture change (notification if moisture didn't rise as expected)
5. Enter deep-sleep until configured time of day (20:00)

3D Printed Parts

All parts should be printed with ASA or PETG, because PLA can start to deteriorate and deform in warm and wet weather conditions.
