The openHAB Sapp binding allows to connect to Picnet Home Automation installations. The binding support multi master configuration too.

The Sapp binding polls the bus in an configurable interval and support sapp over ethernet only, so if you use an old master series without ethernet connection you need to use a Moxa 5110 in order to use it.

For installation of the binding, please see Wiki page Binding

This binding is available from 1.8.0 snapshot

Sapp binding allows to connect multiple masters. Entries in openhab config file should look like below.

sapp:refresh=<value>

which sets refresh interval to Picnet polling service. Value is in milliseconds - default is 100

## pnmas list
sapp:pnmas.ids=home,office

## pnmas definitions (ip and port). Only the pnmas listed in 'sapp:pnmas.ids' are used
sapp:pnmas.home.ip=192.168.2.97
sapp:pnmas.home.port=7001
sapp:pnmas.office.ip=192.168.1.37
sapp:pnmas.office.port=4001

A sample basic configuration could look like:

sapp:refresh=100
sapp:pnmas.ids=home
sapp:pnmas.home.ip=192.168.2.97
sapp:pnmas.home.port=7001

The Picnet Master supports Input Output and Virtual address types.

In the binding we use:

pnmasid status

It is the sapp:pnmas.ids name defined in openhab conf.

Status address type

These values are accepted in order to get the status

• I: Input (valid numbers are from 1 to 250). This is the module address
• O: Output (valid numbers are from 1 to 250). This is the module address
• V: Virtual (valid numbers are from 1 to 2500). This is the virtual number

Status address

It is a number and its value depends from the Status address type as described.

Status subaddress

These values are accepted in order to get the status

• *: The word value
• H: The high byte value
• L: The low byte value
• 1-16: The single bit value
• +: Signed word, -32768 to 32767
• H+: Signed high byte, -128 to 127
• L+: Signed low byte, -128 to 127

Control address type

This values are accepted in order to control the status. Only Virtual is accepted.

• V: Virtual valid numbers are from 1 to 2500. This is the virtual number

Control address

It is a number and the value depends from the Status address type as described.

Control subaddress

These values are accepted in order to control the status

• *: The word value
• H: The high byte value
• L: The low byte value
• 1-16: The single bit value
• +: Signed word, -32768 to 32767
• H+: Signed high byte, -128 to 127
• L+: Signed low byte, -128 to 127

The sapp binding support the following items and their use is listed here:

Switch item syntax:

<pnmasid status>:<status address type, I/O/V>:<status address,1-250/1-250/1-2500>:<status subaddress, */H/L/1-16>:<on value>/<pnmasid control>:<status address type, only V>:<control address, 1-2500>:<control subaddress, */H/L/1-16>:<on value>:<off value>

In this example we control the status of module 60 Output 1 and we control it using Virtual 2001 bit 1 and we send 1 on ON and 1 on OFF command. The Virtual 2001 is autoreset type on master program.

Switch LightDinner  "Dinner Light" (gLight) { sapp="home:O:60:1/home:V:2001:1:1:1" }

How to start and stop polling using a switch item

There is a special switch that can stop and start polling in order to write the Master without stopping Openhab sw.

Switch PollerSwitch "PollerSwitch" { sapp="P" }

Contact item syntax:

// <pnmasid status>:<status address type, I/O/V>:<status address, 1-250/1-250/1-2500>:<status subaddress, */H/L/1-16>:<open value>

In this example we control the status of module 12 Input 7.

Contact ContactWindowsBath "Bath Window" { sapp="home:I:12:7" }

The contact status is by default inverted, so NC contact for is OPEN and NO is CLOSED. To invert the status just add :0 at the end of the string just like the example:

Contact ContactWindowsBath "Bath Window" { sapp="home:I:12:7:0" }

Number item syntax:

<pnmasid status>:<status address type, I/O/V>:<status address, 1-250/1-250/1-2500>:<status subaddress, */H/L/1-16>

Number item come with scale system included. For example in order to scale a word value /10 you can use :0:6553 like example. Default scale depends on address type (0-65535 for word, 0-255 for L/H, 0-1 for bit).

Number SappNumber1		"Sapp Number * : Value [%.1f]" { sapp="home:V:200:*:1:1000" }
Number SappNumber2		"Sapp Number H : Value [%.1f]" { sapp="home:V:200:H:0:2500" }
Number SappNumber3		"Sapp Number L : Value [%.1f]" { sapp="home:V:200:L" }
Number SappNumber4		"Sapp Number 1 : Value [%.1f]" { sapp="home:V:200:1" }
Number SappNumber5		"Sapp Number 2 : Value [%.1f]" { sapp="home:V:200:2" }
Number SappNumberX1		"Sapp Number Setpoint : Value [%.1f]" { sapp="home:V:230:*:0:6553" }
Number SappNumberX2		"Sapp Number Setpoint : Value [%.1f]" { sapp="home:V:230:*" }

Rollershutter item syntax:

<pnmasid status>:<status address type, only V>:<status address, 1-2500>:<status subaddress, */H/L/1-16>:<up value>:<down value>/<pnmasid up command>:<status address type, only V>:<control address, 1-2500>:<control subaddress, */H/L/1-16>:<up value>/<pnmasid down command>:<status address type, only V>:<control address, 1-2500>:<control subaddress, */H/L/1-16>:<down value>/<pnmasid stop command>:<status address type, only V>:<control address, 1-2500>:<control subaddress, */H/L/1-16>:<stop value>

In this example we control the status of Virtual 154 from 0 to 100 for percent status. Virtual 155 bit 1 is used for up command, Virtual 155 bit 2 is used for stop command, Virtual 155 bit 3 is used for down command.

Rollershutter BlindBath	 	"Bath Blind" { sapp="home:V:154:*:0:100/home:V:155:1:1/home:V:155:2:1/home:V:155:3:1" }

Dimmer item syntax:

<pnmasid status>:<status address type, only V>:<status address, 1-2500>:<status subaddress, */H/L/1-16>:<increment>

Dimmer item come with scale system included; use L or H in order to scale from 0 to 255 and * in order to scale from 0 to 65535. Here Virtual 25 has value from 0 to 255 with step to 10

Dimmer dimmer1 "dimmer [%d %%]" (gSapp1)  { sapp="home:V:25:L:10" }

If you want to use dimmer in sitemap you can use this definitions:

Switch item=dimmer1 mappings=[INCREASE="+",DECREASE="-", ON="ON", OFF="OFF"]
Switch item=dimmer1 mappings=[0="OFF", 25="25", 50="50", 75="75", 100="100"]
Slider item=dimmer1 sendFrequency=100 switchSupport
