Ecowatt component for Home Assistant

This component makes the signals provided by RTE (https://www.monecowatt.fr) available in Home Assistant.

Ecowatt is a French service giving a trend about the stress of the electricity network for the next few days.

This integration adds 4 entities in Home Assistant, each indicating the alert level of the day: Green, Orange or Red:

These signals can then be used in your automations to adapt your electricity consumption!

This component uses the pyecowatt library.
