Architecture

Services

• https://github.com/Gratheon/hardware-beehive-sensors - sensors repo on client side
• https://github.com/gratheon/telemetry-api - server side

Dev setup

• download Arduino IDE

• under preferences, set this URL as extra sources https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

• ESP32 chips come in different flavours. If you got same component as described in the bill of materials - ESP32, then connect it over USB to your machine

• Choose ESP32-WROOM-DA Module from device list

• Make sure to change Arduino IDE upload speed to 115200 baud under Tools so that your device can receive data when you upload it

• Install DallasTemperature@3.9.0 library in Arduino IDE (DallasTemperature@3.9.0
• Install Adafruit HX711 library in Arduino IDE
• Upload code to the device using a button ->. You should see something like:
• Click on the reset button (FN) on the chip
• Connect to the ESP32 WIFI access point gratheon, use password gratheon
• Open browser and navigate to wifi access point default gateway - http://192.168.4.1
• Enter your WIFI credentials
• Set target URL https://telemetry.gratheon.com/metric/HIVE_ID?api_token=API_TOKEN
  • replace HIVE_ID with your hive ID. You can take that you can take from URL, ex https://app.gratheon.com/apiaries/7/hives/54; here ID is 54
  • replace API_TOKEN with generate token from account settings at https://app.gratheon.com/account
• Click Save button. Your ESP32 will restart and connect to your WIFI network and start sending data to the telemetry API service
