Water

Water is an Irrigation controller web app for EtherRain devices. For more details about the EtherRain Networked Sprinkler Controller, please visit http://www.quicksmart.com/qs_etherrain.html.

Setup

I have not streamlined the setup process (yet...), but here is a guideline of what needs to be done.

Database

Water uses a SQLite database. To create the database, run setup.php. The database can be reset by deleting db/data.db and re-running setup.php.

Configuration file

In config.php:

// EtherRain device settings
$ipaddress = "192.168.0.1";
$port = 8080;
$simulated = true;
$amount_per_min = 0.635;
$num_zones = 2;

This includes the network location of the EtherRain device; it is how the web server will interact with the device. You can choose to simulate the device instead of actually triggering a device. Amount per minute is how many mm of water the lawn gets per minute of watering, and number of zones is used to calculate how much watering time is left.

// Location settings (for time and weather)
$timezone = "America/Edmonton";
$location = "calgary,canada";

This is the physical location of the EtherRain device. It is used to determine time and weather.

// For worldweatheronline.com
$api_key = "get_key_from_worldweatheronline.com";

This is for the weather source. It is required.

Cron Job

Add a cron job to run cron.php while in its directory every 5 minutes. Optionally, log the output by appending it to a file. Weather will be updated on the hour.

*/5 * * * * cd /path/to/water/; php -q cron.php >> cron_log.txt;
