This is based off of the homebridge-opensprinkler plugin originally created by Tim Charper used under the ISC license.

OpenSprinkler

"Hey Siri, turn off my sprinklers."

"Hey Siri, are the Back Patio sprinklers on?"

Overview

Simple OpenSprinkler / Homebridge integration.

What works:

• Read and set rain delay
• Automatically update changes in state
• Show sprinkler state: idle, scheduled, running
• Show remaining duration
• Turn off sprinklers
• Ad-hoc turn on a single valve at a time.
• Allow duration to be specified per-station when enabled

What doesn't work:

• Starting multiple programs in sequence (turning on multiple stations causes them to run concurrently)
• Persisting Home-configured station-specific default durations after restart
• Does not support multiple OpenSprinkler systems

Installation

You must have NodeJS v10.17.0 or later. Check your node version:

node --version

You need Homebridge installed and configured. This plugin was developed against Homebridge 1.0.0.

npm install -g homebridge

Install this plug-in:

npm install -g homebridge-opensprinkler-system

Updating:

npm update -g homebridge-opensprinkler-system

Add the section below to your homebridge platforms section.

Configuration

• host: The IP or DNS name of the OpenSprinkler controller
• password: Either the md5 hash of the password, or the password in plain text. I.E. {"md5": "a6d82bced638de3def1e9bbb4983225c"} or {"plain": "opendoor"}
• defaultDurationSecs: The duration for which a station will be run when toggled on.
• pollIntervalMs: The interval at which homebridge-opensprinkler will poll for state changes in OpenSprinkler.

Sample configuration:

{
  "platform": "OpenSprinkler",
  "host": "sprinkler.lan",
  "password": {"md5": "a6d82bced638de3def1e9bbb4983225c"},
  "defaultDurationSecs": 600,
  "pollIntervalMs": 5000
}
