I've spent the last 2-3 years working on a pet project that turned into what has now become the Intellidwell Sprinkler Controller.
Being an Electrical Engineer with a passion for programming and building network systems, it provided the perfect environment for this project to come to fruition.
All contained inside a custom 3-D printed enclosure designed to fit over a power outlet, this controller exhibits the following main features:
- Up to 10 zones
- Wi-Fi integration
- Controls accessible from any browser without the need for an app
- Simple On/off, Individually timed, or fully scheduled control available
- No automatic or voluntary connection to services outside your local network. You will never be reliant on another company's cloud service
- Integration with Home assistant available
- User controlled Rain Delay (1-5 days)
Nitty Gritty:
- Solid State Relay control for maximum longevity of valve control
- A modular ESP32 controller design for easy replacement or software/firmware upgrades
- MQTT integration for compatibility with Home Assistant
- Custom and efficient 24VAC to 5VDC converter for controller and logic
- Fall Back AP mode
- Micropython and html utilized to continually serve a microdot server in AP and WiFi modes
I've personally been using this controller seemlessly for over a year now and I think you could enjoy doing the same.
