Properties

Available Properties

Valve item has 2 required properties: Active and InUse. Active determines whether it is meant to be on and InUse determines whether it is currently flowing water.

Characteristic Optional/Required Characteristic Properties (to enable property)
Active Required
InUse Required
SetDuration Optional {"SetDuration":{"minValue":300, "maxValue":1200}
RemainingDuration Optional Incoming property only
ValveType Optional {"ValveType":{"minValue":1,"maxValue":1} sets as "sprinkler"

SetDuration will control and be set by this in the Home app:

Details

Characteristic Format Accepted Values Notes
Active int 0, 1 {"Active":0} / {"Active":1}
InUse int 0, 1 {"InUse":0} / {"InUse":1}
SetDuration uint32 0 - 3600 Seconds, step value = 1
RemainingDuration uint32 0 - 3600 Seconds, step value = 1
ValveType int 0 - 3 Known values: 0=generic valve, 1=sprinkler; step value=1

Possible Combinations

The combination of Active and InUse characteristics will determine what the Home app shows for the valve item. Here is a table showing all combinations:

Active InUse Home app Shows
{"Active":0} {"InUse":0} Off
{"Active":0} {"InUse":1} Stopping
{"Active":1} {"InUse":0} Idle
{"Active":1} {"InUse":1} Running

Examples

These examples are meant to be copied into your Node-RED system and adapted to your setup.

I. 4 Zone Sprinkler connected to OpenSprinkler

This is a fully functional sprinkler system with 4 zones which is connected to OpenSprinkler running on the same Raspberry Pi as Node-RED. The example is set up so that each of 4 zones can be turned on independently. If any zone is running, the "whole yard" zone will also show that it is running. When turning on a zone, a default is set for 10 minutes (600 seconds). This can be changed with the Default Time inject node.

Functions:

  • "Hey Siri, turn on Front Yard for 15 minutes" will water the front yard for 15 minutes
  • Turning on "Whole Yard" will run OpenSprinkler program number 1
  • "Whole Yard" remaining duration is a sum of each queued zone
  • Does not interfere with normal operation of OpenSprinkler, only shows status and allows control from HomeKit

Characteristic Properties

These properties define the sprinkler to show as a "sprinkler" in HomeKit (rather than a generic faucet) and define that the zone show with a "SetDuration" option (so the duration may be set from HomeKit).

{
    "ValveType":
    {
        "minValue":1,
        "maxValue":1
    },
    "SetDuration":
    {
        "minValue":300,
        "maxValue":1800
    }
}

Important notes:

The topic must be set in HomeKit to filter nodes based on incoming topic.

III. Sprinkler using a simple outlet (e.g. Philips Hue)

  • Duration is configurable and remaining duration time will be displayed in the Home App.
  • Implementation in a simple loop
  • My Osram Smart Plug attached to Philips Hue Bridge can be controlled by boolean characteristic "On", for other characteristics change function nodes as required
  • Configure default duration (used each time after relaunching Node-red) in "Init" node
  • Configure min/max and step characteristics in "Irrigation" node
