Python library for interacting with SenzWifi (Pentair Thermal WiFi) API to control thermostats

python-senz-wifi-module

Python library for interacting with the SenzWifi (Pentair Thermal WiFi) API to control thermostats.

Features

• Async-first — built on httpx for efficient async operations
• Authentication & session management — automatic retry on session expiry
• Thermostat control — list, read, and update thermostat settings
• Convenience methods — set temperature, turn off, boost mode
• Real-time notifications — long-polling for thermostat state changes
• CLI tool — built-in command-line interface for quick operations
• Fully typed — type hints throughout with py.typed marker

Installation

pip install senzwifi

Or install from source:

git clone https://github.com/sockless-coding/python-senz-wifi-module.git
cd python-senz-wifi-module
pip install -e .

Quick Start

Using the Library

import asyncio
from senzwifi import AsyncSenzWifi, RegulationMode

async def main():
    # Create client with credentials
    async with AsyncSenzWifi("[e-mail]", "your-password") as client:
        # Authenticate
        await client.authenticate()

        # List all thermostats
        response = await client.get_thermostats()
        for group in response.groups:
            print(f"Group: {group.group_name}")
            for t in group.thermostats:
                print(f"  {t.room}: {t.temperature_celsius:.1f}°C (mode: {RegulationMode(t.regulation_mode).name})")

        # Set a thermostat to 21°C manually
        await client.set_manual_temperature("SN123456789", 21.0)

        # Turn off a thermostat
        await client.turn_off("SN123456789")

        # Start boost mode (3 hours by default)
        await client.start_boost("SN123456789")

asyncio.run(main())

Using the CLI

# List all thermostats
senzwifi --username "[e-mail]" --password "your-password" list

# Get a specific thermostat
senzwifi --username "[e-mail]" --password "your-password" get SN123456789

# Set temperature to 21°C
senzwifi --username "[e-mail]" --password "your-password" set SN123456789 21.0

# Turn off a thermostat
senzwifi --username "[e-mail]" --password "your-password" off SN123456789

# Start boost mode
senzwifi --username "[e-mail]" --password "your-password" boost SN123456789

API Reference

AsyncSenzWifi

The main client class. Supports use as an async context manager.

async with AsyncSenzWifi(email, password) as client:
    await client.authenticate()
    # ... use the client

Constructor

Parameter	Type	Default	Description
email	str	—	Account email address
password	str	—	Account password
max_retries	int	3	Maximum retry attempts for failed requests
timeout	float	30.0	Request timeout in seconds

Methods

authenticate() -> AuthResponse

Authenticate and obtain a session ID.

auth = await client.authenticate()
if auth.is_success:
    print(f"Logged in as {auth.email}")

get_thermostats() -> ThermostatsResponse

Fetch all thermostats grouped by their group.

response = await client.get_thermostats()
for group in response.groups:
    print(f"{group.group_name}: {len(group.thermostats)} devices")

# Get all thermostats flat
all_thermostats = response.get_all_thermostats()

# Find a specific thermostat
t = response.get_thermostat("SN123456789")

get_thermostat(serial_number: str) -> Thermostat

Get a specific thermostat by serial number.

t = await client.get_thermostat("SN123456789")
print(f"{t.room}: {t.temperature_celsius:.1f}°C")

set_manual_temperature(serial_number: str, temperature_celsius: float) -> UpdateThermostatResponse

Set a thermostat to a specific temperature in manual mode.

result = await client.set_manual_temperature("SN123456789", 21.5)
print(f"Success: {result.success}")

turn_off(serial_number: str) -> UpdateThermostatResponse

Turn off a thermostat.

result = await client.turn_off("SN123456789")

start_boost(serial_number: str, end_time: datetime | None = None) -> UpdateThermostatResponse

Start boost (comfort) mode. Defaults to 3 hours from now if no end time is specified.

from datetime import datetime, timedelta, timezone

# Boost for 3 hours (default)
await client.start_boost("SN123456789")

# Boost until a specific time
end = datetime.now(timezone.utc) + timedelta(hours=1)
await client.start_boost("SN123456789", end_time=end)

update_thermostat(serial_number: str, thermostat: Thermostat) -> UpdateThermostatResponse

Update a thermostat with custom settings.

t = await client.get_thermostat("SN123456789")
t.regulation_mode = RegulationMode.SCHEDULE
t.manual_temperature = 2000  # 20.0°C in raw format
result = await client.update_thermostat("SN123456789", t)

wait_for_notification(timeout: float = 300.0) -> Notification | None

Long-poll for thermostat state change notifications.

notification = await client.wait_for_notification(timeout=60.0)
if notification:
    print(f"Change detected: {notification.action} on {notification.thermostat.room}")

Models

RegulationMode

RegulationMode.SCHEDULE   # 1 — Use the configured schedule
RegulationMode.BOOST      # 2 — Boost / comfort temp mode
RegulationMode.MANUAL     # 3 — Constant temp mode
RegulationMode.OFF        # 5 — Off

Thermostat

Key properties (all temperatures available in both raw and Celsius):

Property	Type	Description
serial_number	str	Device serial number
room	str	Room name
group_name	str	Group name
temperature_celsius	float	Current temperature
regulation_mode	int	Current regulation mode
online	bool	Whether the device is online
heating	bool	Whether heating is active
manual_temperature_celsius	float	Manual setpoint temperature
comfort_temperature_celsius	float	Comfort/boost temperature
min_temp_celsius	float	Minimum temperature
max_temp_celsius	float	Maximum temperature

Temperature Conversion Utilities

from senzwifi import temp_to_celsius, celsius_to_temp

# Raw API value (1/100 °C) → Celsius
temp_to_celsius(2100)  # 21.0

# Celsius → raw API value
celsius_to_temp(21.0)  # 2100

Exceptions

Exception	Description
SenzWifiError	Base exception for all errors
AuthenticationError	Authentication failed
SessionExpiredError	Session has expired
DeviceNotFoundError	Thermostat not found
APIError	API request failed

Example: Monitoring Thermostats

See examples/monitor.py for a complete example that monitors thermostat changes in real time.

import asyncio
from senzwifi import AsyncSenzWifi, RegulationMode

async def monitor():
    async with AsyncSenzWifi("[e-mail]", "your-password") as client:
        await client.authenticate()

        # Show initial state
        response = await client.get_thermostats()
        for t in response.get_all_thermostats():
            mode = RegulationMode(t.regulation_mode).name
            print(f"[INIT] {t.room}: {t.temperature_celsius:.1f}°C ({mode})")

        # Watch for changes
        while True:
            notification = await client.wait_for_notification()
            if notification:
                t = notification.thermostat
                mode = RegulationMode(t.regulation_mode).name
                print(f"[CHANGE] {t.room}: {t.temperature_celsius:.1f}°C ({mode})")

asyncio.run(monitor())
