Temperature Broadcast Application

The Temperature Broadcast application is used to notify units on the C-Bus network of changes in temperature. It is

used to allow temperature control systems to react to changes in environmental conditions.

This has been replaced by the Measurement application (not get implemented by libcbus).

Please refer to this document in conjunction with the Temperature Broadcast Application Guide published by Clipsal.

class cbus.protocol.application.temperature.TemperatureApplication

Bases: object

This class is called in the cbus.protocol.applications.APPLICATIONS dict in order to describe how to decode

temperature broadcast application events recieved from the network.

Do not call this class directly.

classmethod decode_sal(data, packet)
