A Python API for interacting with LVI/Purmo Touch E3-connected radiators

CleverTouch - interact with Touch E3-connected radiators

This Python API enables control and monitoring of Touch E3-connected radiators via CleverTouch cloud accounts.

Background

LVI by Purmo is range of radiators manufactured by the Finnish company Purmo. Some models, such as Yali Digital, Parada and Ramo may be monitored and controlled centrally using the optional accessory TempCo Touch E3. The Touch E3 may in turn be controlled remotely via a CleverTouch cloud account and related mobile and web apps.

General usage

All communication with the cloud API is asynchronous using aiohttp. Communication can either use lower-level calls using an ApiSession object with methods for returning unparsed data objects, or a higher-lever object model using the Account with friendly functions and objects for the most relevant properties of homes and devices.

The most useful methods/properties of the most relevant objects are listed below. A full description of the functionality is only available by reading the source code.

Other brands

While untested, a number of other product lines seem to be using the same controller and software with different branding.

Applications using the following URLs might work, fully or partially, by specifying the host argument when creating an Account or ApiSession (see below).

• Walter Meier Metalplast smart-comfort - https://www.smartcomfort.waltermeier.com
• Frico PF Smart - https://fricopfsmart.frico.se
• Fenix V24 Wifi - https://v24.fenixgroup.eu
• Vogel & Noot E3 App - https://e3.vogelundnoot.com
• CordiVari My Way Cosy Home - https://cordivarihome.com

Additionally, Watts Vision (https://smarthome.wattselectronics.com) uses the same app but a different/improved authentication process. Work is needed to support that process within this library.

Other implementations / GitHub repositories

There are available alternative implementations with unknown status of functionality available on GitHub.

• Watts Vision support for Home Assistant is provided through the repo pwesters/watts_vision.
• A Watts Vision library is also available in mjkl-gh/aio-watts-vision.
• Library support for LVI heaters can be found in hwaastad/pylvi with Home Assistant support in hwaastad/lvi.
• An alternative solution to support Home Assistant by streaming values via MQTT is available in komppa/tempco2mqtt.

Using the higher-level API

See samples/demo.py for a basic but functional example of how to use the higher-level API.

The Account object

Methods	Description
Account(**host)	Create an Account object. Optionally specifying the host (including protocol), defaulting to https://e3.lvi.eu.
authenticate(email, password)	Authenticate with the service.
get_user()	Returns a refreshable User object containing info about all available homes.
get_home(id)	Returns a refreshable Home object for a home with the specific id.
get_homes()	Returns a list of all homes registered with the user.

The User object

Properties/Methods	Description
homes	Dictionary containing id and basic information about all available homes.
refresh()	Refreshes the data from the cloud account.

The Home object

Properties/Methods	Description
info	Provides an object with basic info about the home.
devices	A list with all available devices.
refresh()	Refreshes the data from the cloud account.

The Radiator object

Properties/Methods	Description
label	The user-specified name of the radiator.
zone	Info about the zone where the radiator is located.
temperatures	A dictionary with temperatures.
heat_mode	The current heat mode.
set_temperature(name,value,unit)	Send a request to update a temperature setting.
set_heat_mode(heat_mode)	Send a request to update the heat mode.

Using the lower-level API

The ApiSession object

Methods	Description
ApiSession()	Create an API session.
authenticate(email, password)	Authenticate with the service.
read_user_data()	Return unparsed data about the user associated with the account.
read_home_data(id)	Return unparsed data about the home with the specified id.
write_query(id, params)	Send a raw update query for a specific home

Integrations

This API was primarily written to be able to integrate Touch E3-radiators in Home Assistant, see https://github.com/hemphen/hass-clevertouch.
