Greenhouse Tracking

This application uses deep sleep mode, wakes up every 10 minutes, reads the sensor (temperature, humidity), and sends Telegram notifications if the temperature is out of the "comfort zone".

The user can temporarily mute cold/hot notifications using a relevant Telegram bot command. In this case, the bot will send that notification only after the temperature gets back to the "comfort zone" and then gets too cold/hot again.

Config file

The application uses a config file to read important settings. The config file should be stored on the LittleFS filesystem in the /config.json file.

{
  "telegram_bot_token": "XXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
  "telegram_chat_id": "XXXXXXXXXX",
  "temperature_min": 16,
  "temperature_max": 30,
  "thingspeak_channel_id": 1111111,
  "thingspeak_write_api_key": "XXXXXXXXXXXXXXXX"
}

Configuration options

• telegram_bot_token (string): The API token for the Telegram bot that will be used for notifications.
• telegram_chat_id (string): The chat ID for the Telegram chat that will receive notifications. Use @myidbot to find out the chat ID of an individual or a group. Could contain a few chat IDs, comma separated.
• temperature_min, temperature_max (integer): When the temperature goes out of these boundaries, the bot will send a notification.
• thingspeak_channel_id (integer): Channel ID on ThingSpeak.com.
• thingspeak_write_api_key (integer): Write API Key for the channel.

Copy an example config file from data/config.example.js to data/config.js and fill in your Telegram bot API token, ThingSpeak channel ID and write API key, as well as other settings. Upload the file into the filesystem.
