Firmware for the Open AIR Valve by The Flamingo

ESPHome Open Air Valve

Visit https://esphome.io/ for instructions on how to deploy this firmware.

More documentation might come available in future updates. Make sure to copy example.secrets.yaml to secrets.yaml and fill it with your own wifi credentials.

Change the device name's (esphome->name) x in open-air-valve.yaml with a number or a letter to help you identify the valve in your setup.

Sensor Support: SHT-31

More info about this sensor and ESPhome : https://esphome.io/components/sensor/sht3xd.html

If you want to add a SHT-31 moisture & Temperature sensor to the Open AIR Valve. Add the following code at the bottom of open-air-valve.yaml

sensor:
  - platform: sht3xd
    temperature:
      name: "Temperature Open AIR Valve x"
    humidity:
      name: "Humidity Open AIR Valve x"
    address: 0x44
    update_interval: 60s

Sensor Support: Senseair S8

More info about this sensor and ESPhome : https://esphome.io/components/sensor/senseair.html?highlight=co2+senseair

If you want to add a Senseair S8 Co2 sensor to the Open AIR Valve. Add the following code at the bottom of open-air-valve.yaml

sensor:
  - platform: senseair
    co2:
      name: "Co2 Open AIR Valve x"
    update_interval: 60s

Combination of Senseair S8 & SHT-31 in one Sensor

If you have a combination sensor add the following to the bottom of open-air-valve.yaml

sensor:
  - platform: sht3xd
    temperature:
      name: "Temperature Open AIR Valve x"
    humidity:
      name: "Humidity Open AIR Valve x"
    address: 0x44
    update_interval: 60s
  - platform: senseair
    co2:
      name: "Co2 Open AIR Valve x"
    update_interval: 60s

SHT-20 Sensor

If you have a SHT-20 Sensor add the following code at the bottom of open-air-valve.yaml

sensor:
  - platform: custom
    lambda: |-
      auto sht20 = new SHT20();
      App.register_component(sht20);
      return {sht20->temperature_sensor, sht20->humidity_sensor, sht20->vpd_sensor, sht20->dew_point_sensor};
    sensors:
      - name: "Temperature Open AIR Valve x"
        id: sensor_temperature
        unit_of_measurement: °C
        accuracy_decimals: 2
      - name: "Humidity Open AIR Valve x"
        id: sensor_humidity
        unit_of_measurement: "%"
        accuracy_decimals: 2
      - name: "Open AIR Valve x Vapour-pressure deficit"
        id: sensor_vpd
        unit_of_measurement: "kPa"
        accuracy_decimals: 2
      - name: "Open AIR Valve x Dew point"
        id: sensor_dew_point
        unit_of_measurement: °C
        accuracy_decimals: 2

Add the following righ below "board: esp32dev"

  libraries:
    - Wire
    - u-fire/uFire SHT20@^1.1.1
  includes: sht20.h

Place the SHT20.H file in the same directory as the open-air-valve.yaml. Thanks

@wre Thanks for your support on this sensor implementation

Change all the 'x' in the document for a number or a letter so you know which valve is which. (if sensors have identical names they wont show up in HA)
