Tellduslive Component

This component adds support for the Telldus Live service.
Telldus Live is the online service used with Tellstick Net devices.

For more details about this platform, please refer to the documentation at
https://home-assistant.io/components/sensor.tellduslive/

Developer access to the Telldus Live service is neccessary
API keys can be aquired from https://api.telldus.com/keys/index

Tellstick Net devices can be auto discovered using the method described in:
https://developer.telldus.com/doxygen/html/TellStickNet.html

It might be possible to communicate with the Tellstick Net device
directly, bypassing the Tellstick Live service.
This however is poorly documented and yet not fully supported (?) according to
http://developer.telldus.se/ticket/114 and
https://developer.telldus.com/doxygen/html/TellStickNet.html

API requests to certain methods, as described in
https://api.telldus.com/explore/sensor/info
are limited to one request every 10 minutes
