Actions

Key	Action	Description
"0"	OFF	(default)
"1"	ON

A water valve has two actions. The Digital Outputs "r": [{}] for each should be configured to attain the desired state.

Sensor Type

Sensor Type defined by the "w" key contained within the accessory object.

Type	Name	Description
0	Water Valve	(default)
1	Sprinkler
2	Shower
3	Tap / Faucet

Set the sensor type to indicate what type of water accessory is attached e.g. "w": 2 indicates a sprinkler is attached.

A variety of one-wire sensors are available and supported by HAA.

Maximum Use Time

Maximum use time is defined by the "d" key contained within the accessory object.

Key	State	Description
"d"	0	Timer disabled
	3600	Timer set to 1 hour (default)
	1 to ∞	Time in seconds to set the use time

This option limits the maximum amount of time that the water valve can be in the ON state. The default is to limit the valve on time to 3,600 seconds (1 hour), but this time period can be disabled, lengthened or shortened.

When the timer is enabled then the valve will be turned OFF after the maximum use time has elapsed.

State Inputs

State inputs are defined by an "f[n]" key contained within the accessory object. Where [n] is the number of the associated state.

Key	Required State
"f0"	Valve Off
"f1"	Valve On

ICMP Ping Inputs

ICMP Ping inputs are defined by an "q[n]" key contained within the accessory object. Where [n] is the number of the associated state.

Key	State
"q0"	Set state to On
"q1"	Set state to Off

Refer to ICMP Ping Inputs for more detail and examples.

Accessory Notifications

The list of notifications "m" supported by a water valve are as follows:

Value	Notification

Key	State	Description
"s"	0	OFF (default)
	1	ON
