node-screenlogic

This is a Node.JS library for interfacing with Pentair ScreenLogic systems over your local network or remotely through the Pentair dispatcher. Local connections require a Pentair ScreenLogic device on the same network (a network which supports UDP broadcasts).

Tested with a Pentair ScreenLogic system on firmware versions 5.2 Build 736.0 Rel, 5.2 Build 738.0 Rel

Usage

See example.js for an example of interfacing with the library. Broadly, import the library with

const ScreenLogic = require('node-screenlogic');

then for local connections create a new ScreenLogic unit finder with

new ScreenLogic.FindUnits();

Hook its serverFound event with

.on('serverFound', function(server) { })

and call it via search(). This performs a UDP broadcast on 255.255.255.255, port 1444, so ensure your network supports UDP broadcasts and the device is on the same subnet.

Alternatively, to find a unit remotely, create a new ScreenLogic remote login with

new ScreenLogic.RemoteLogin('Pentair: xx-xx-xx')

Hook its gatewayFound event with

.on('gatewayFound', function(unit) { })

and call it via connect(). This opens a TCP connection to screenlogicserver.pentair.com, port 500.

When a local or remote server is found, create a new UnitConnection with

new ScreenLogic.UnitConnection(server);

or

new ScreenLogic.UnitConnection(unit.port, unit.ipAddr, '1234')

where '1234' is the remote login password.

Once you've connected with connect(), there are a number of methods available and corresponding events for when they've completed successfully. See UnitConnection API reference.

All communication with a ScreenLogic unit is done via TCP, so responses will come back in the order they were requested.

Notes

Contributions welcome. There are lots of available messages supported by ScreenLogic that the app doesn't support yet, but can be added pretty easily as needed.

Packet format

All ScreenLogic packets are sent with an 8-byte header. The first 2 bytes are a little-endian-encoded sender ID (which is normally specified when making the original request). The second 2 bytes are a little-endian-encoded message ID. The final 4 bytes are a little-endian-encoded length of the data payload on the packet. The data payload is handled per-message.

API Reference

Pull requests to document undocumented properties are most welcome.

FindUnits

constructor()

Examples:

const ScreenLogic = require('node-screenlogic');

var finder = new ScreenLogic.FindUnits();

search()

Issues one UDP broadcast search for available units. Since this is a stateless UDP query, the connection will not automatically be closed, so you may need to issue another search if the first one doesn't work, if your network connection is not established, etc. There is no automatic timeout or retry mechanism built in to this command.

close()

Closes the socket.

Events

• close - Indicates that close() has been called on the finder.
• error - Indicates that an unhandled error was caught.
• serverFound - Indicates that a ScreenLogic unit has been found. Event handler receives a UnitConnection object.

Examples:

finder.on('serverFound', function(server) {
  var client = new ScreenLogic.UnitConnection(server);
})

• error - Indicates that an unhandled error was caught (such as the connection timing out)

RemoteLogin

constructor(systemName)

Argument is the name of a system to connect to in "Pentair: xx-xx-xx" format.

Example:

const ScreenLogic = require('./index');

var remoteLogin = new ScreenLogic.RemoteLogin('Pentair: xx-xx-xx');

connect()

Connects to the dispatcher service and searches for the unit passed to its constructor.

close()

Closes the connection

Events

• close - Indicates that the connection to the remote login server has been closed. Event handler receives a bool indicating whether there was a transmission error.
• error - Indicates that an unhandled error was caught (such as the connection timing out).
• gatewayFound - Indicates that the search for the named unit has completed (may or may not be successful). Event handler receives a SLGetGatewayDataMessage argument.

UnitConnection

constructor(server)

Argument is a server returned from FindUnits serverFound event.

Examples:

finder.on('serverFound', function(server) {
  var client = new ScreenLogic.UnitConnection(server);
})

remoteLogin.on('gatewayFound', function(unit) {
  if (unit && unit.gatewayFound) {
    var client = new ScreenLogic.UnitConnection(unit.port, unit.ipAddr, '1234'));
  }
});

constructor(port, address, password)

Port is an integer. Address is an IPv4 address of the server as a string. Password is optional; should be the 4-digit password in string form, e.g. '1234'.

Examples:

var client = new ScreenLogic.UnitConnection(80, '10.0.0.85', '1234')

connect()

Connects to the server passed to its constructor.

Examples:

var client = new ScreenLogic.UnitConnection(server);
client.connect();

close()

Closes the connection.
