API Reference

Everything below is auto-generated from the source docstrings. The public surface is curated via __all__ in proconip.__init__, so anything importable as from proconip import … shows up here.

Top-level package

Async Python library for interacting with the ProCon.IP pool controller.

BadCredentialsException

Bases: ProconipApiException

Raised when the controller rejects the request with HTTP 401 or 403.

Almost always means the username or password in the ConfigObject is wrong.

Source code in src/proconip/api.py

class BadCredentialsException(ProconipApiException):
    """Raised when the controller rejects the request with HTTP 401 or 403.

    Almost always means the username or password in the `ConfigObject` is wrong.
    """

BadStatusCodeException

Bases: ProconipApiException

Raised on any unexpected HTTP error status (4xx or 5xx) other than 401/403.

The original aiohttp.ClientResponseError is preserved as the cause and can be inspected via __cause__ if the status code or response details are needed.

DmxControl

Convenience wrapper that binds a session and config for DMX I/O.

Construct once with your aiohttp.ClientSession and ConfigObject, then read or write DMX channels without repeating those arguments each time.

The constructor also binds a default timeout for every call made via this wrapper. Each method then accepts an optional per-call timeout that overrides the bound default when supplied.

Example

dc = DmxControl(session, config)
dmx = await dc.async_get_dmx()
for ch in dmx:
    dmx.set(ch.index, (ch.value + 64) % 256)
await dc.async_set(dmx)

Convenience wrapper that binds a session and config for relay control.

Construct once with your aiohttp.ClientSession and ConfigObject, then switch relays by aggregated relay ID (an integer) instead of constructing Relay instances by hand.

Aggregated relay IDs run from 0 to 7 for the eight built-in relays and 8 to 15 for the eight optional external relays.

The constructor also binds a default timeout for every call made via this wrapper. Each method then accepts an optional per-call timeout that overrides the bound default when supplied.

Example

rs = RelaySwitch(session, config)
state = await GetState(session, config).async_get_state()
await rs.async_switch_on(state, relay_id=2)

Async API client (proconip.api)

api

Async HTTP client for the ProCon.IP pool controller.

The controller exposes four HTTP endpoints — /GetState.csv for sensor and relay state, /GetDmx.csv for DMX channel state, /usrcfg.cgi for configuration writes (including manual relay switching and DMX updates), and /Command.htm for manual dosage commands. This module wraps all four with typed exceptions and a configurable per-request timeout.

Each operation is available in two equivalent forms:

• Free async functions like async_get_state and async_switch_on. These take an aiohttp.ClientSession and ConfigObject explicitly, which makes them composable in larger applications that already manage their own session lifecycle.
• OO wrappers like GetState, RelaySwitch, DosageControl, and DmxControl. These bind the session and config once at construction and expose ergonomic instance methods so callers don't have to repeat those arguments on every call.

The OO wrappers delegate to the free functions, so behavior is identical.

All requests use HTTP Basic auth and run inside an asyncio.timeout block that covers both the request and the response body read. Network failures, HTTP error codes, and timeouts are all mapped to ProconipApiException subclasses so callers can handle them uniformly.

ProconipApiException

Bases: Exception

Base exception for any failed API call.

Catch this if you want to handle all controller-side and network failures uniformly. The more specific subclasses below let you distinguish auth, HTTP, and timeout problems when that's useful.

GetState

Convenience wrapper that binds a session and config for state reads.

Construct once with your aiohttp.ClientSession and ConfigObject, then call async_get_state() (parsed) or async_get_raw_state() (CSV) without repeating those arguments each time.

The constructor also binds a default timeout for every call made via this wrapper. Each method then accepts an optional per-call timeout that overrides the bound default when supplied.

DmxControl

Convenience wrapper that binds a session and config for DMX I/O.

Construct once with your aiohttp.ClientSession and ConfigObject, then read or write DMX channels without repeating those arguments each time.

The constructor also binds a default timeout for every call made via this wrapper. Each method then accepts an optional per-call timeout that overrides the bound default when supplied.

Example

dc = DmxControl(session, config)
dmx = await dc.async_get_dmx()
for ch in dmx:
    dmx.set(ch.index, (ch.value + 64) % 256)
await dc.async_set(dmx)

async_switch_on(client_session: ClientSession, config: ConfigObject, current_state: GetStateData, relay: Relay, timeout: float = 10.0) -> str

Manual mode overrides the controller's schedule until the relay is explicitly switched off or set back to auto. Other relays in current_state are preserved by reading their bit field, which is why a fresh GetStateData snapshot is required.

Dosage relays (chlorine, pH+, pH-) cannot be switched on this way — the controller's safety logic interlocks them. Use async_start_dosage (or DosageControl) instead for time-limited manual dosing.

Data structures (proconip.definitions)

definitions

Data structures for the ProCon.IP CSV and form-encoded HTTP APIs.

This module contains everything that's needed to describe the controller's data shape without making any network calls — typed wrappers around the CSV responses, helpers for the bit-field flags they encode, and a few small exceptions that get raised when something is malformed.

Path constants (API_PATH_*) and category strings (CATEGORY_*) are exposed because the rest of the library and downstream callers (notably a Home Assistant integration) build on them.

The classes you will most often work with are:

• ConfigObject — base URL plus credentials.
• GetStateData — parsed /GetState.csv response. Exposes individual sensors, relays, dosage flags, and a few derived helpers.
• Relay — convenience wrapper around a relay DataObject with on/off and manual/auto interrogation methods.
• GetDmxData / DmxChannelData — parsed and mutable representation of the 16 DMX channels.

DosageTarget

Bases: IntEnum

Identifies which dosing pump a manual dosage command should engage.

The numeric values match the controller's MAN_DOSAGE query parameter, so this enum can be used directly in URL building.

Relay

Bases: DataObject

A DataObject with extra methods for interrogating a relay's state.

Relay state is encoded in two bits of the underlying value:

• bit 0 — output level (0 = off, 1 = on)
• bit 1 — control mode (0 = auto, 1 = manual)

The four valid combinations correspond to the four display_value strings from DataObject._relay_state.

Construct one by passing the DataObject you got from GetStateData.relay_objects (or external_relay_objects); the relay's column, name, calibration, and raw value are copied across so the physical value is computed exactly once. GetStateData.get_relay() is a shorthand that does this for you.

Parsed representation of a single /GetState.csv response.

The CSV the controller returns has six lines: SYSINFO, names, units, offsets, gains, and raw values. The constructor parses all six and builds a list of DataObject instances, then groups them by category for easy lookup.

Once constructed, an instance is read-only — it represents a snapshot. Re-fetch and reconstruct the object whenever you need fresh data.

All public properties on this class are populated eagerly at construction time, so accessing them is cheap.

post_data property

post_data: dict[str, str]

Form payload that updates the DMX channel state via /usrcfg.cgi.

The dict has five keys, all required by the controller:

• TYPE: always "0".
• LEN: always "16" (channels per write).
• CH1_8: comma-separated values for channels 1–8.
• CH9_16: comma-separated values for channels 9–16.
• DMX512: always "1".

URL-encode and join with & to produce the actual POST body — see proconip.api.async_set_dmx for the canonical encoding.

get_value

get_value(index: int) -> int

Return the current value of the channel at index.

Equivalent to self[index].value. Provided for symmetry with set.

def get_value(self, index: int) -> int:
    """Return the current value of the channel at ``index``.

    Equivalent to ``self[index].value``. Provided for symmetry with
    `set`.
    """
    return self._channels[index].value

set

set(index: int, value: int) -> None

Update the value of one channel.

Values outside the [0, 255] range are silently clamped — the controller's DMX hardware only accepts 8-bit values, so callers rarely need anything else.

PARAMETER	DESCRIPTION
index	Zero-based channel index (0 for channel 1, 15 for channel 16). TYPE: int
value	New intensity. Clamped to [0, 255]. TYPE: int

RAISES	DESCRIPTION
IndexError	If index is not in 0–15.

BadRelayException

Bases: Exception

Raised when a relay argument doesn't make sense in context.

The two main cases are: switching a dosage relay on directly (rejected by proconip.api.async_switch_on), and passing a non-relay DataObject to GetStateData.is_dosage_relay.

InvalidPayloadException

Bases: Exception

Raised when a CSV response from the controller cannot be parsed.

Typically this means the response was empty, truncated, or did not have the expected number of CSV lines. Catching this lets callers distinguish protocol-level breakage from network errors.
