Automatic Watering System Control App

This is a tiny Node.js application for controlling and configuring the Automatic Watering System.

Requirements

You need to have:

Node.js (16.x or newer) installed on your system.
A serial-radio gateway attached to your system. This gateway an be an using an Arduino for example.

Before you can start you need to install the required node_modules once by running the following command inside of the control directory.

npm install

Start the app:

npm start

Then open your browser and navigate to http://127.0.0.1:3000/.

You may also set your own listen host and port using this:

HOST=0.0.0.0 PORT=1337 npm start

Hint: All communication is only on your localhost and through RadioHead. No data is send over the internet! 🙂

On the Website you have to configure your connection first.

Once you are connected to the serial-radio gateway you can:

Interact with the watering system
See all the received information (adc and DHT values, battery status, turned on channels)
Turn on or off a channel
Read the current settings from the watering system
Send new settings to the watering system
See the software version of the watering system
Send pings and receive pongs

Sometimes a command cannot be send to the watering system, or the watering system sends not the expected answer. This happens if the controller for the watering system is busy while sending the command. Simply try again after some seconds! 😉
Error Resource temporarily unavailable Cannot lock port when trying to reconnect to a serial port: This a bug in Node.js 20. Try updating to a recent Node.js version >20.11.1.
