screenlogicpy

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

Installation

The screenlogicpy package can be installed from PyPI using pip.

$ pip install screenlogicpy

Library usage

Changed in v0.5.0: The screenlogicpy library has moved over to using asyncio for all network I/O. Relevant methods now require the async/await syntax.
New in v0.8.0: Support for Python 3.8 and 3.9 is being phased out across future releases. Version 0.8.x will be the last versions to support Python 3.8.
New in v0.9.0: Support for Python 3.8 has been removed. Support for Python 3.9 is being phased out across future releases. Version 0.9.x will be the last versions to support Python 3.9.
New in v0.10.0: Support for Python 3.9 has been deprecated. Additionally, support for Python 3.10 is being phased out across future releases. Versions 0.10.x will be the last versions to support Python 3.10.

The ScreenLogicGateway class is the primary interface.

from screenlogicpy import ScreenLogicGateway

    gateway = ScreenLogicGateway()

Changed in v0.5.0: Instantiating the gateway no longer automatically connects to the protocol adapter or performs an initial update.
Changed in v0.7.0: Passing adapter connection info when instantiating the gateway is deprecated and will be removed in a future release. Connection info should be passed to async_connect() instead.
Changed in v0.8.0: Support for passing connection info to gateway constructor is fully deprecated and has been removed. Ability to specify client id used for push subscriptions, and to specify maximum number of times to retry a request has replaced it.

Connecting to a ScreenLogic Protocol Adapter

Once instantiated, use async_connect() to connect and login to the ScreenLogic protocol adapter, and gather the pool configuration.

If disconnected, this method may be called without any parameters to reconnect with the previous connection info, or with new parameters to connect to a different host.

await gateway.async_connect("192.168.x.x")

New in v0.5.0.
Changed in v0.7.0: async_connect() now accepts adapter connection info. This supports handling ip changes to the protocol adapter.
Changed in v0.10.0: async_connect() no longer returns a bool indicating success. If the action is unsuccessful, an exception indicating the failure mode is raised.

Polling the pool state

Once connected, all available state information can be polled with the async_update() coroutine.

await gateway.async_update()

This update consists of sending requests for:

Current pool status
Detailed information for each configured pump
Detailed pool chemistry information
Status and settings for any configured salt chlorine generators
The controller's current date and time, and auto DST settings

Warning: This method is not rate-limited. The calling application is responsible for maintaining reasonable intervals between updates. The ScreenLogic protocol adapter may respond with an error message if too many requests are made too quickly.

Changed in v0.5.0: This method is now an async coroutine and no longer disconnects from the protocol adapter after polling the data.
Changed in v0.10.0: Now includes polling for information regarding the controller's date and time settings.

Subscribing to pool state updates

The preferred method for retrieving updated pool data is to subscribe to updates pushed to the gateway by the ScreenLogic system. This reduces network traffic compared to polling, and improves responsiveness to state changes.

To enable push updates, subscribe to a particular message code using gateway.async_subscribe_client(callback, message_code), passing a callback method to be called when that message is received, and the message code to subscribe to. This function returns a callback that can be called to unsubscribe that particular subscription.

The gateway's ClientManager will automatically handle subscribing and unsubscribing as a client to the ScreenLogic protocol adapter upon the first callback subscription and last unsub respectively.

from screenlogicpy.const import CODE

def status_updated():
    # Do something with the updated data    

unsub_method = await gateway.async_subscribe_client(status_updated, CODE.STATUS_CHANGED)

Example in ./examples/async_client.py

Multiple callbacks can be subscribed to a single message code. Additionally, a single global callback may be subscribed to multiple message codes.
Note: Each combination of callback and code will result in a separate unique unsub callback. The calling application is responsible for managing and unsubing all subscribed callbacks as needed.

Pushed data

While the ScreenLogic system does support some push updates, not all state information for all equipment available via push. The two main state update messages that can be subscribed to are:

General status update containing
- Air and water temperature and heater states
- Basic status indicators such as Freeze mode and active delays
- Circuit states
- Basic chemistry information
IntelliChem controller status update containing
- Detailed chemistry information

The status of any pumps or salt chlorine generators is not included in any push updates. To supplement this, the different data sets can now be requested individually.

New in v0.7.0.

Polling specific data

To update a specific set of data, you can use any of the following methods:

# Updates the basic status of the pool controller. *Same as pushed data
await gateway.async_get_status()

# Updates the state of all configured pumps
await gateway.async_get_pumps()

# Updates the detailed chemistry information from a IntelliChem controller. *Same as pushed data
await gateway.async_get_chemistry()

# Updates the state of any configured salt chlorine generators
await gateway.async_get_scg()

# Updates the current pool controller time and Daylight Saving Time adjustments setting
await gateway.async_get_datetime()

Push subscriptions and polling of all or specific data can be used on their own or at the same time.
Warning: Some expected data keys may not be present until a full update has been performed. It is recommended that an initial full async_update() be preformed to ensure the gateway's data dict is fully primed.

New in v0.7.0.

Using the data

The ScreenLogicGateway class caches all data from the ScreenLogic protocol adapter as a single dict object for continued reference by the consuming application. This includes any data processed via push or polling. The consuming application may get this data at anytime with the get_data() method.

data = gateway.get_data()

get_data() now supports specifying a path directly to the data desired. A path can be any length. By default, if the data path is not found, get_data() will return None, similar to dict.get(). Alternatively strict=True keyword argument can be added to force the ScreenLogicGateway to raise a KeyError exception if the path is not found.

The majority of data points normally available to the end-user via the official apps are presented as dict objects containing "name" and "value" keys/pairs. Additional keys may be present depending on the type of data.

For example, let's consider the following scenario:

gateway._data = {
    "controller": {
        "sensor": {
            "air_temperature": {
                "name": "Air Temperature",
                "value": 57,
                "unit": "°F",
                "device_type": "temperature",
                "state_type": "measurement",
            },
        }
    }
}
data_path = ("controller", "sensor", "air_temperature")

temperature_sensor = gateway.get_data(*data_path)

Here, temperature_sensor would be a dict of all key/value pairs under the "air_temperature" key.

The ScreenLogicGateway also provides shortcut methods get_name() and get_value() to get the "name" or "value" values respectively from the specified data path.

# sensor_value = 57
sensor_value = gateway.get_value(*data_path)

# sensor_name = "Air Temperature"
sensor_name = gateway.get_name(*data_path)

To get other values directly, use get_data() with the full key path:

# sensor_unit = "°F"
sensor_unit = gateway.get_data("controller", "sensor", "air_temperature", "unit")

New in v0.9.0.

Disconnecting

When done, use async_disconnect() to unsubscribe from push updates and close the connection to the protocol adapter.

await gateway.async_disconnect()

New in v0.5.0.

Gateway Discovery

The discovery module's async_discover() function can be used to get a list of all discovered ScreenLogic protocol adapters on the local network. Each protocol adapter is represented as a dict object that can then be directly used to instanciate a ScreenLogicGateway class.

Note: Gateway discovery is limited to discovering ScreenLogic protocol adapters on the same subnet.

hosts = await discovery.async_discover()

Changed in v0.5.0: This method is now an async coroutine.

Example in ./examples/async_discovery.py

Basic Implementation Example

from screenlogicpy import ScreenLogicGateway, discovery

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

Full example in ./examples/gateway.py

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
Set chlorinator output levels and super-chlorination values
Setting IntelliChem chemistry values
Setting the pool controller's system date and time

If the action is unsuccessful, an exception will be raised indicating the failure mode. Note: The methods do not confirm the requested action is now in effect on the pool controller.

Changed in v0.10.0: Actions no longer return a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Turning a circuit ON or OFF

A circuit can be requested to be turned on or off with the async_set_circuit() method. async_set_circuit takes two required arguments, circuitID which is the id number of the circuit as an int, and circuitState which represents the desired new state of the circuit, as an int. See State below.

await gateway.async_set_circuit(circuitID, circuitState)

Changed in v0.5.0: This method is now an async coroutine.
Changed in v0.10.0: No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting a heating mode

The desired heating mode can be set per body of water (pool or spa) with async_set_heat_mode(). async_set_heat_mode takes two required arguments, body as an int representing the body of water, and mode as an int of the desired heating mode.

await gateway.async_set_heat_mode(body, mode)

Changed in v0.5.0: This method is now an async coroutine.
Changed in v0.10.0: No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting a target temperature

The target heating temperature can be set per body of water (pool or spa) with async_set_heat_temp(). async_set_heat_temp takes two required arguments, body as an int representing the body of water, and temp as an int of the desired target temperature.

await gateway.async_set_heat_temp(body, temp)

Changed in v0.5.0: This method is now an async coroutine.
Changed in v0.10.0: No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting light colors or shows

Colors or color-shows can be set for compatible color-enable lighting with async_set_color_lights(). async_set_color_lights takes one required argument, light_command as an int representing the desired command/show/color

await gateway.async_set_color_lights(light_command)

Changed in v0.5.0: This method is now an async coroutine.
Changed in v0.10.0: No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting chlorinator output levels, super chlorination

Chlorinator output levels can be set with async_set_scg_config(). async_set_scg_config takes up to four keyword arguments, pool_setpoint, spa_setpoint, super_chlorinate, and super_chlor_timer. All are int with super_chlorinate representing an ON or OFF state. See State below.

await gateway.async_set_scg_config(pool_setpoint=pool_output, spa_setpoint=spa_output)

New in v0.5.0.
Changed in v0.10.0:
- Added super_chlorinate, and super_chlor_timer parameters to control super chlorination functions.
- Now accepts keyword arguments only. This allows the caller to specify only the value(s) they want to update, retaining all other existing values.
- No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting IntelliChem chemistry values

Chemistry values used in the IntelliChem system can be set with async_set_chem_data(). async_set_chem_data takes up to six keyword arguments, ph_setpoint, orp_setpoint, calcium_hardness, total_alkalinity, cyanuric_acid, and salt_tds_ppm. ph_setpoint is a float and the rest are int.

await gateway.async_set_chem_data(ph_setpoint=ph, orp_setpoint=orp, calcium_hardness=cal, total_alkalinity=alk, cyanuric_acid=cya, salt_tds_ppm=salt)

New in v0.6.0.
Changed in v0.10.0:
- Added calcium_hardness, total_alkalinity, cyanuric_acid, and salt_tds_ppm parameters.
- Now accepts keyword arguments only. This allows the caller to specify only the value(s) they want to update, retaining all other existing values.
- No longer returns a bool indicating success. If the action is unsuccessful, an exception is raised indicating the failure mode.

Setting controller date and time

The system date and time in the pool controller can be set with async_set_date_time(). Method takes up to two keyword arguments, date_time as a python datetime object and auto_dst as an int representing an ON or OFF state. See State below.

await gateway.async_set_date_time(date_time=datetime.now(), auto_dst=set_dst)

New in v0.10.0.

Handling unsolicited messages

With the move to asyncio, screenlogicpy can now handle unsolicited messages from the ScreenLogic protocol adapter (messages that are not a direct response to a request from screenlogicpy). To do so, you need to tell the ScreenLogicGateway what message code to listen for and what to do when it is received. You can register a handler with register_message_handler() . This method takes the message code to wait for, the async coroutine to schedule when a message is received, and any parameters you want to pass to your handler. Your handler coroutine needs to accept the bytes message itself, and any additional parameters you specified.

Notes:

Currently the ScreenLogicGateway must be connected to the protocol adapter before registering a handler.
Registering a handler in this way does not subscribe the gateway to push state updates from the ScreenLogic system.

Example:

WEATHER_UPDATE_CODE = 9806
WEATHER_REQUEST_CODE = 9807

async def weather_request(message: bytes, data: dict):
    result = await gateway.async_send_message(WEATHER_REQUEST_CODE)
    decode_weather(result, data)
    print(data)

gateway.register_async_message_handler(WEATHER_UPDATE_CODE, weather_request, data)

Remove the handler with:

gateway.remove_async_message_handler(WEATHER_UPDATE_CODE)

Example in ./examples/async_listen.py

New in v0.7.0.

Debug Information

A debug function is available in the ScreenLogicGateway class: get_debug. This will return a dict with the raw bytes for the last response for each request the gateway performs during an update. This can be useful for debugging the actual responses from the protocol adapter.
Note: Currently only includes polled data.

last_responses = gateway.get_debug()

New in v0.5.5.

Command line

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

Basic usage

$ screenlogicpy

Without 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.

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 protocol adapter to connect to.
Note: If the IP address is not specified, screenlogicpy will attempt to discover ScreenLogic protocol adapters on the local network, and connect to the first one that responds. This is generally fine if you only have one ScreenLogic protocol adapter. Discovery is limited to finding protocol adapters on the same subnet as the host running screenlogicpy.

`-p, --port`
