Homeassistant DWD Illuminance Sensor

Estimates outdoor illuminance based on current weather conditions and time of day. At night the value is 10. From a little before sunrise to a little after the value is ramped up to whatever the current conditions indicate. The same happens around sunset, except the value is ramped down. Below is an example of what that might look like over a three day period.

The following sources of weather data are supported:

Deutscher Wetterdienst

This Integration is based on https://github.com/pnbruckner/ha-illuminance and only a fork to support DWD (Deutscher Wetter Dienst). If you are using another weather provider, please be sure to use the integration from pnbrucker instead of this one. I will only support DWD, as pnbrucker wont merge my DWD Commits (pnbruckner#17).

You can also have my integration and pnbrucker's integration installed at the same time, as this integration was renamed.

Follow the installation instructions below. Then add the desired configuration. Here is an example of a typical configuration:

sensor:
  - platform: dwd_illuminance
    entity_id: weather.dwd_weather_home

Installation

Place a copy of:

__init__.py at <config>/custom_components/dwd_illuminance/__init__.py sensor.py at <config>/custom_components/dwd_illuminance/sensor.py manifest.json at <config>/custom_components/dwd_illuminance/manifest.json

where <config> is your Home Assistant configuration directory.

Or add this github repository to HACS to install it via HACS.

NOTE: Do not download the file by using the link above directly. Rather, click on it, then on the page that comes up use the Raw button.
