This Python API enables control and monitoring of Touch E3-connected radiators via CleverTouch cloud accounts.
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.
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.
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).
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.
There are available alternative implementations with unknown status of functionality available on GitHub.
See samples/demo.py for a basic but functional example of how to use the higher-level API.

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