screenlogicpy 0.1.0

Interface for Pentair ScreenLogic connected pool controllers over IP via Python

screenlogicpy

screenlogicpy is an interface for Pentair ScreenLogic connected pool controllers over IP via python.

Installation

The screenlogicpy package can be installed from PyPI using pip.

$ pip install screenlogicpy

Library usage

The ScreenLogicGateway class is the primary interface.

from screenlogicpy import ScreenLogicGateway
gateway = ScreenLogicGateway("192.168.x.x")

Gateway Discovery

The discovery module's discover() function can be used to get a list of all discovered ScreenLogic gateways on the local network. Each gateway is represented as a dict object that can then be directely used to instanciate a ScreenLogicGateway class.

from screenlogicpy import ScreenLogicGateway, discovery

hosts = discovery.discover()
if len(hosts) > 0:
    gateway = ScreenLogicGateway(**hosts[0])
    data = gateway.get_data()
else:
    print("No gateways found")

Querying data

The ScreenLogicGateway class updates all data at once from the ScreenLogic gateway. That data is cached as a dict object for continued reference by the consuming application. The consuming application may get this data at anytime with the get_data() method.

data = gateway.get_data()

Updating the data

When instanciated, the ScreenLogicGateway class object will perform an initial update of all available data to populate it's internal cache. A consuming application may request further updates of the internal data with the update() method.

gateway.update()

After update(), The consuming application may then querry the new data with get_data().

Note: This update consists of

1. Connecting and logging-on to the specified ScreenLogic gateway.
2. Sending requests for
   1. Pool controller configuration
   2. Current pool status
   3. Detailed information for each configured pump
   4. Detailed pool chemistry information
3. Closing the connection to the gateway.

Warning: This method is not rate-limited. The calling application is responsible for maintaining reasonable intervals between updates.

Performing actions

The following actions can be performed with methods on the ScreenLogicGateway object:

• Set a specific circuit to on or off
• Set a heating mode for a specific body of water (spa/pool)
• Set a target heating temperature for a specific body of water (spa/pool)
• Select various color-enabled lighting options

Each method will return True if the opperation reported no exceptions. Note: The methods do not confirm the requested action is now in effect on the pool controller.

Turning a circuit ON or OFF

A circuit can be requested to be turned on or off with the set_circuit() method. set_circuit takes two required arguments, circuitID which is the id number of the circuit as an int, and circuitState which repesents the desired new state of the circuit, as an int: 0 = off, 1 = on.

success = gateway.set_circuit(circuitID, circuitState)

Setting a heating mode

The desired heating mode can be set per body of water (pool or spa) with set_heat_mode(). set_heat_mode takes two required arguments, body as an int: 0 = Pool, 1 = Spa, and mode as an int of the desired heating mode: 0 = Off, 1 = Solar, 2 = Solar Prefered, 3 = Heater, 4 = Don't Change.

success = gateway.set_heat_mode(body, mode)

Setting a target temperature

The target heating temperature can be set per body of water (pool or spa) with set_heat_temp(). set_heat_temp takes two required arguments, body as an int: 0 = Pool, 1 = Spa, and temp as an int of the desired target temperature.

success = gateway.set_heat_temp(body, temp)

Setting light colors or shows

Colors or color-shows can be set for compatible color-enable lighting with set_color_lights(). set_color_lights takes one required argument, light_command as an int representing the desired command/show/color: 0 = Off, 1= On, 2 = Color Set, 3 = Color Sync, 4 = Color Swim, 5 = Party, 6 = Romantic, 7 = Caribbean, 8 = American, 9 = Sunset, 10 = Royal, 11 = Save, 12 = Recall, 13 = Blue, 14 =Green, 15 = Red, 16 = White, 17 = Magenta, 18 = Thumper, 19 = Next, 20 = Reset, 21 = Hold.

success = gateway.set_color_lights(light_command)

Command line

Screenlogicpy can also be used via the commannd line. The primary design is for the command line output to be consume/parsed by other applications and thus by default is not very human-readable. For more human-friendly output, specify the -v option.

Basic usage:

$ screenlogicpy

Withou any arguments, screenlogicpy will attempt to discover a gateway on the LAN, and display a human readable "dashboard" of the current state of their pool.

Argument usage:

$ screenlogicpy [-h] [-v] [-i IP] [-p PORT] {discover,get,set} ...

Optional arguments

-h, --help

Argparse help command. Available at any stage of positional commands.

-v, --verbose

Tells screenlogicpy to be a little more verbose in it's output. Friendlier for humans.

-i, --ip

$ screenlogicpy -i xxx.xxx.xxx.xxx

Specify the IP address of the ScreenLogic gateway to connect to. Note: If the IP address is not specified, screenlogicpy will attempt to discover ScreenLogic gateways on the local network, and connect to the first one that responds. This is generally fine if you only have one ScreenLogic gateway.

-p, --port

$ screenlogicpy -i xxx.xxx.xxx.xxx -p xx

Specify the port of the ScreenLogic gateway to connect to. Needs to be used in conjunction with -i, --ip option.

Positional arguments

discover

$ screenlogicpy discover

Attempts to discover ScreenLogic gateways on the local network via UDP broadcast. Returns [ip address]:[port] of each discovered ScreenLogic gateway, one per line.

get

$ screenlogicpy get {circuit,c,heat-mode,hm,heat-temp,ht,heat-state,hs,current-temp,t,json,j}

The get option is use with additionl options to return the current state of the additional option specified.

circuit, c

$ screenlogicpy get circuit [circuit number]

Returns 1 for on and 0 for off

heat-state, hs

$ screenlogicpy get heat-state [body]

Returns the current state of the heater for the specified boty of water. The current state will match the heat mode when heating is active, otherwise will be 0 (off). Note: body can be body number (0 or 1) or pool or spa.

current-temp, t

$ screenlogicpy get current-temp [body]

heat-mode, hm

$ screenlogicpy set heat-mode [body] [heat mode]

Sets the desired heating mode for the specified body of water. Note: body can be body number (0 or 1) or pool or spa. heat mode needs to be an int corrisponding to the desired mode: 0 = Off, 1 = Solar, 2 = Solar Prefered, 3 = Heater, 4 = Don't Change.

heat-temp, ht
