This is a simple system based on the ESP8266 (in my case a nodeMCUv2 development board) which will keep my plants watered whenever I'm not home.
Goal: bare minimum running system consisting of:
- Up to 4 plants being watered
- Regular intervalls, defaulting to something like watering once per week
- Rough setting for the amount of water each plant will receive
- Use moisture sensors for each plant
- Data log for each plant
- Water sensor to warn, when reservoir needs to be filled
- Push notifications using Telegram bot
