Two variant are available. One with a closed top and one with a cutout for mounting a breakout board. TODO: Add pictures # Settings The WiFi, ThingSpeak and MQTT settings can be configured via a web interface:  If you do not want to use ThingSpeak simply leave the `ThingSpeak API key` field empty. Similarly the MQTT can be disabled by leaving the `MQTT base topic` empty. At first boot the module will turn on a hotspot with the SSID: `PlantFriends` and password: `plantsarecool`. After logging on to the WiFI simply navigate to or to configure the module. The device can be put back into hotspot mode by shorting the TX and RX pins and restarting the module. A new firmware and file system image can be uploaded by navigation to or . ## Calibrating the soil moisture sensor Click "Calibrate Soil moisture sensor". Follow the instructions. Some handy tips: - Don't get the electronics wet, only the sensor part - When doing the wet calibration, use a half full glass of water (or half empty if you are that tye of person). Half of the sensor should be in water. Otherwise the readings when the sensor is put in soil will be very low. - If you need to redo a step in the calibration, just refresh the page. Images of the wet and dry calibration are shown below: # [Home Assistant](https://www.home-assistant.io/) Simply activate [MQTT discovery](https://www.home-assistant.io/docs/mqtt/discovery/) by adding the following to your `configuration.yaml` file: ```yaml mqtt: discovery: true ``` Assuming your plant is named `office` it will now show up as a sensor like so:  TODO: Upate this image! The name of the plant is taken from the `MQTT base topic` and get be chaned via the [HTTP settings](#Settings) page. ## Advanced Home Assistant configuration This section will guide you through on how to set the `sleep time`, `watering delay`, `watering threshold` and `watering time` directly via the Home Assitant overview page. First add the following to your `configuration.yaml` file: ```yaml input_number: office_sleep_time: name: Sleep Time min: 10 max: 60 step: 5 icon: mdi:sleep unit_of_measurement: min office_watering_delay: name: Watering Delay min: 0 max: 360 step: 10 icon: mdi:timer-sand unit_of_measurement: min office_watering_threshold_pct: name: Watering Threshold Pct min: 0 max: 100 step: 0.1 icon: mdi:target unit_of_measurement: pct office_watering_time: name: Watering Time min: 1 max: 30 step: 1 icon: mdi:water-pump unit_of_measurement: s office_automatic_ota: name: Automatic OTA min: 0 max: 1 step: 1 icon: mdi:cellphone-arrow-down ``` This will create four [sliders](https://www.home-assistant.io/integrations/input_number/), one for each parameter. Remember to replace `office` with the `MQTT base topic` you have set via the web interface. Now add the following to your `automations.yaml` file: ```yaml - alias: Plant set slider trigger: - platform: mqtt topic: 'plant/+/config' action: - service: input_number.set_value data_template: entity_id: input_number.{{ trigger.topic.split('/')[1] }}_sleep_time value: "{{ trigger.payload_json.sleep_time | float }}" - service: input_number.set_value data_template: entity_id: input_number.{{ trigger.topic.split('/')[1] }}_watering_delay value: "{{ trigger.payload_json.watering_delay | float }}" - service: input_number.set_value data_template: entity_id: input_number.{{ trigger.topic.split('/')[1] }}_watering_threshold_pct value: "{{ trigger.payload_json.watering_threshold_pct | float }}" - service: input_number.set_value data_template: entity_id: input_number.{{ trigger.topic.split('/')[1] }}_watering_time value: "{{ trigger.payload_json.watering_time | float }}" - service: input_number.set_value data_template: entity_id: input_number.{{ trigger.topic.split('/')[1] }}_automatic_ota value: "{{ trigger.payload_json.automatic_ota | float }}" - alias: Plant slider moved trigger: - platform: state entity_id: - input_number.office_sleep_time - input_number.office_watering_delay - input_number.office_watering_threshold_pct - input_number.office_watering_time - input_number.office_automatic_ota action: - service: mqtt.publish data_template: # The topic should always be the after the dot and before the name of the variable we want to set topic: "plant/{{ trigger.entity_id.split('.')[1].split('_')[:-2] | join('_') }}/config" retain: true payload: > {% set topic = trigger.entity_id.split('.')[1].split('_')[:-2] | join('_') %} { "sleep_time": {{ states('input_number.' + topic + '_sleep_time') | int }}, "watering_delay": {{ states('input_number.' + topic + '_watering_delay') | int }}, "watering_threshold": {{ states('input_number.' + topic + '_watering_threshold_pct') | int }}, "watering_time": {{ states('input_number.' + topic + '_watering_time') | int }}, "automatic_ota": {{ ((states('input_number.' + topic + '_automatic_ota') | int) > 0) | tojson }} } ``` This makes sure that the MQTT config topic is updated when the slider is moved and that the slider is always set to the MQTT config topic when it changes. Finally you can add the sensors and the inputs slider into on group by adding the following to `groups.yaml`: ```yaml office_plant: name: "Office Plant" icon: mdi:sprout entities: - sensor.office_soil_moisture_pct - sensor.office_voltage - sensor.office_battery - sensor.office_temperature - sensor.office_pressure - sensor.office_humidity - input_number.office_sleep_time - input_number.office_watering_delay - input_number.office_watering_threshold_pct - input_number.office_watering_time - input_number.office_automatic_ota ``` Note that the `temperature`, `pressure` and `humidity` sensors are only available if a BME280 is connected. The plant will now show up in the Home Assistant overview like so:  TODO: Update this image # ThingSpeak TODO: Add guide
