openHAB - Solid State Relay Bricklet

Warning

The openHAB bindings are still in beta, but the development was stopped.

This is the description of the openHAB API bindings for the Solid State Relay Bricklet. General information and technical specifications for the Solid State Relay Bricklet are summarized in its hardware description.

An installation guide for the openHAB API bindings is part of their general description.

Thing

Required firmware version:
  • 2.0.0
Firmware update supported:
  • yes

Channels

Relay

Switches the relay. A running monoflop timer for the relay will be aborted if the relay is toggled by this channel.

Type:
  • Switch
UID:
  • tinkerforge:brickletsolidstaterelay:[UID]:BrickletSolidStateRelayRelay
Read only:
  • No
Monoflop Relay

Triggers a monoflop as configured

Type:
  • Commands (String)
UID:
  • tinkerforge:brickletsolidstaterelay:[UID]:BrickletSolidStateRelayMonoflopRelay
Read only:
  • No
Commands:
  • Accepts any string
Parameters:
  • Monoflop Duration – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • The time that the relay should hold the configured value.

  • Monoflop Value – Type: boolean, Default: true
  • The desired value of the specified channel. Activated means relay closed and Deactivated means relay open.

Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:brickletsolidstaterelay:[UID]")
val hwVersion = actions.brickletSolidStateRelayGetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletSolidStateRelaySetState(boolean state)
Parameters:
  • state – Type: boolean, Default: false

Sets the state of the relays true means on and false means off.

A running monoflop timer will be aborted if this function is called.

brickletSolidStateRelayGetState()
Return Map:
  • state – Type: boolean, Default: false

Returns the state of the relay, true means on and false means off.

Advanced Actions

brickletSolidStateRelaySetMonoflop(boolean state, long time)
Parameters:
  • state – Type: boolean
  • time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

The first parameter is the desired state of the relay (true means on and false means off). The second parameter indicates the time that the relay should hold the state.

If this function is called with the parameters (true, 1500): The relay will turn on and in 1.5s it will turn off again.

A monoflop can be used as a failsafe mechanism. For example: Lets assume you have a RS485 bus and a Solid State Relay Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds. The relay will be on all the time. If now the RS485 connection is lost, the relay will turn off in at most two seconds.

brickletSolidStateRelayGetMonoflop()
Return Map:
  • state – Type: boolean
  • time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]
  • timeRemaining – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

Returns the current state and the time as set by Monoflop Relay as well as the remaining time until the state flips.

If the timer is not running currently, the remaining time will be returned as 0.

brickletSolidStateRelayGetIdentity()
Return Map:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char, Range: ['a' to 'h', 'z']
  • hardwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • firmwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • deviceIdentifier – Type: int, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here.
