This library was created primarily to be used together with Home Assistant, but can be used as a stand-alone library as well. The API used by this library is sanctioned by Huum to be used by third parties. At least to the extent that they happily provided documentation for the API when asked about it.

This library has been tested against a Huum Drop sauna using the UKU Wi-Fi control unit.

No guarantees are given when using this library. You are using it at your own risk. Saunas can be dangerous if used without care or without the right security measures.

pip install huum

poetry add huum

import asyncio

from huum.huum import Huum

async def turn_on_sauna():    
    huum = Huum(username="foo", password="bar")
    
    # If you don't have an existing aiohttp session
    # then run `open_session()` after initilizing
    await huum.open_session()
    
    # Turn on the sauna
    await huum.turn_on(80)

asyncio.run(turn_on_the_sauna())

The huum package is fully asynchronous.

Supported Python versions:

Authentication uses username password. The same credentials that you use for logging into the Huum application.

Passing credentials to constructor

huum = Huum(username=<username>, password=<password>)

You can use the library either with an already existing session or create one yourself. This design decision was created mainly to support Home Assistants (HA) existing sessions and complying with their guidelines. In most cases you will want to create your own session if you are using this outside of HA.

If you already have an existing session you can pass it to the constructor using the session argument.

huum = Huum(session=<session>)

If you want the library to create a new session, run open_session() after creating a Huum instance. You must do this before running any commands. You can close the session using close_session().

huum = Huum()
huum.open_session()
...
huum.close_session()

The Huum API exposes a status endpoint for getting the current status of the sauna. This will return the basic information about the sauna. It will however not return all of the info that the sauna could give you when the sauna is not heating. You will however get this info if you try turning off the sauna again after it is already off. For that reason, this library exposes two methods of getting the status of the sauna, status() and status_from_status_or_stop(). The latter will first call the status endpoint, and if the sauna is off, then call the off endpoint to get the full status response.

The main difference, and the main reason to use the latter endpoint, is that status() will not give you the previously set temperature of the sauna is off, while status_from_status_or_stop() will.

huum.status()

huum.status_from_status_or_stop()

The Huum API does not have a specific endpoint for turning on a setting the temperature. The same endpoint does both. This library has two functions for turning on and settings the temperature, mainly for exposing a nicer interface to the developer.

# Turns on the sauna and sets its temperature to 80
huum.turn_on(temperature=80)

# Identical the the above
huum.set_temperature(temperature=80)

Huums API does not check if the sauna door is open or not when turning it on. It will happily turn on the sauna while the door is open. The sauna itself will most likely still not heat as it has a security guard in the sauna, but it will turn it on and will start heating if the door is closed. The Huum mobile application however checks if the sauna door is open or closed before turning on the sauna.

To mimic the security guards of the mobile application the library, by default, checks the status of the sauna before it turns it on. If you do not want to have this check, then you can pass the argument safety_override=True to either turn_on() or set_temperature.

huum.set_temperature(temperature=80, safety_override=True)

The sauna can be turned off by calling turn_off().

huum.turn_off()

This library uses Pydantic schemas for all method responses. I recommend checking the /huum/schemas.py for checking responses.

This library implements custom exceptions for most of its calls. You can find them in the exceptions.py file. But in short these are the exceptions triggered:

All of exceptions triggered by the library inherit from HuumError.

If the door is open and the sauna is turned on, and the client is not told to explicitly bypass security measures (see "Security concerns" above), then huum.exceptions.SafetyException will be raised.
