# HomePlantery
[Plantwatery](https://github.com/Lumics/Plantwatery) but with ESPHome (based on [ESPlanty](https://community.home-assistant.io/t/esplanty-self-watering-solar-powered-plant-no-plumbing-no-powerpoints-irrigation-deep-sleep-battery/464263))

__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.__
## Schematic
[Fritzing Schematic](./doc/schematic_perfboard.fzz)
# Software
## Requirements
- [Home Assistant](https://www.home-assistant.io/)
- [ESPHome integration](https://www.home-assistant.io/integrations/esphome/)
- Create [Input Boolean Helper integration](https://www.home-assistant.io/integrations/input_boolean/) with id `input_boolean.ota_update_available`
## Code
[plant_watering_control.yaml](./homeassistant/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.
## Electronics Case
- [Bottom Case](./3dprint/case/electronics/electronics_case_bottom.stl) with holes for ESP32 USB-C, TP4056 micro USB, Slide Switch, Cable holes
