OpenSprinkler Binding

This binding allows good and flexible control over your OpenSprinkler devices. You can choose to manually start, stop or delay the stand alone watering programs that are stored and run fully from the OpenSprinkler device. Alternatively you can setup openHAB rules to control everything in more depth by setting up multiple station things for each watering zone to gain more in depth control. By using the internal programs and sensors of the OpenSprinkler device, it can remove the complexity of what happens to the watering if openHAB crashes, is rebooted, or drops out of WiFi range in the middle of your watering rules. Mixing the two concepts can also be done, the choice is yours.

Supported Bridges

• OpenSprinkler HTTP Bridge is required to communicate with an OpenSprinkler device through the network and should be added first.

Supported Things

• OpenSprinkler Station is for gaining advanced controls and status information over a single station (zone) of a device, e.g. to turn it on or off, or the time remaining.
• OpenSprinkler Device is for device-specific controls that usually apply to multiple stations or main unit sensors, e.g. if rain was detected.

Recommend that you first add a single device thing and then if you need the extra controls, add as many of the station things as you wish.

Discovery

OpenSprinkler devices can be discovered by the binding sending requests to every IP on your network. Due to this method used, it is very slow at finding devices and can saturate network bandwidth.

Bridge ('http') Configuration

• hostname: Hostname or IP address of the OpenSprinkler HTTP API.
• port: Port the OpenSprinkler device is listening on. Usually 80.
• password: Admin password of the API. Factory default is: opendoor
• refresh: Number of seconds in between refreshing the Thing state with the API.
• basicUsername: (optional) Only needed when the OpenSprinkler device is behind a basic auth enforcing reverse proxy.
• basicPassword: (optional) Only needed when the OpenSprinkler device is behind a basic auth enforcing reverse proxy.

Station Thing Configuration

The station thing must be used with a http bridge and has the following configuration properties:

• stationIndex: The index of the station to communicate with, starting with 0 for the first station

Channels

The following channels are supported by the station thing.

Channel Type ID	Item Type		Description
stationState	Switch	RW	This channel indicates whether the station is on or off.
remainingWaterTime	Number:Time	R	The time the station remains to be open.
nextDuration	Number:Time	RW	The amount of time that will be used to keep the station
			open when next manually switched on. If not set, this
			value will default to 18 hours which is the maximum time
			supported.
queued	Switch	RW	Indicates that the station is queued to be turned on.
			The channel cannot be turned on, only turning it off is
			supported (which removes the station from the queue).
ignoreRain	Switch	RW	This channel makes the station ignore the rain delay.

When using the nextDuration channel, it is advised to setup persistence (e.g. MapDB) in order to persist the value through restarts.

The following channels are supported by the device thing. NOTE: Some channels will only show up if the hardware has the required sensor and is setup correctly.

Channel Type ID	Item Type		Description
rainsensor	Switch	RO	This channel indicates whether rain is detected by the device or not.
sensor2	Switch	RO	This channel is for the second sensor (if your hardware supports it).
currentDraw	Number:ElectricCurrent	RO	Shows the current draw of the device.
waterlevel	Number:Dimensionless	RO	This channel shows the current water level in percent (0-250%). The water level is
			calculated based on the weather and influences the duration of the water programs.
signalStrength	Number	RO	Shows how strong the WiFi Signal is.
flowSensorCount	Number:Dimensionless	RO	Shows the number of pulses the optional water flow sensor has reported.
programs	String	RW	Displays a list of the programs that are setup in your OpenSprinkler and when
			selected will start that program for you.
stations	String	RW	Display a list of stations that can be run when selected to the length of time set
			in the nextDuration channel.
nextDuration	Number:Time	RW	The time the station will open for when any stations are selected from the
			stations channel. Defaults to 30 minutes if not set.
resetStations	Switch	RW	The ON command will stop all stations immediately, including those waiting to run.
enablePrograms	Switch	RW	Allow programs to auto run. When OFF, manually started stations will still work.
rainDelay	Number:Time	RW	Sets/Shows the amount of time (hours) that rain has caused programs to be delayed.
