# Live Sun, Moon, and Planets for Home Assistant

[![hacs_badge](https://img.shields.io/badge/HACS-Custom-orange.svg)](https://github.com/partofthething/ha_skyfield)

This is a custom component for [Home Assistant ](https://www.home-assistant.io/) 

that makes a live polar sun path chart for your location. Besides the Sun, it

also shows the Moon and a few major planets. Plus, it shows the Winter and Summer solstice sun paths so you can see where you are in the seasons!

This uses the [skyfield library](https://rhodesmill.org/skyfield/) to do the computations. 

To use: 

* Install this in your `custom_components` folder

* Download the prerequisites: `pip3 install skyfield matplotlib numpy` (no longer

  necessary with hassio!)

* Add the following to your home assistant config:

```yaml

camera:

    platform: ha_skyfield

    show_constellations: false

```

* Add a picture entity to your GUI with this camera. It will update live.

Optional configuration:

* `show_time` add a timestamp to the plot

* `show_legend` add a legend of the bodies

* `show_constellations` enable or disable the constellations (default is True).

* `planet_list` customize which planets are shown

* `constellations_list` customize which constellations are shown (use names from

  [here](https://github.com/partofthething/ha_skyfield/blob/master/custom_components/ha_skyfield/constellations_by_RA_Dec.dat))

* `north_up` (boolean) puts North at the top (useful in the Southern Hemisphere)

* `horizontal_flip` (boolean) flips projection horizontally

* `image_type` (string) Optional - provide image format extension.  Tested options are `png` (default) and `jpg`.

Known Issues:

* WARNING: High CPU usage! The underlying library is relatively long-running. Disable or

  limit constellations if you're using a smaller computer, like a Raspberry Pi. Even with

  them off, the CPU load may unacceptable. Options and more 

  discussion in [#4](https://github.com/partofthething/ha_skyfield/issues/4)

* Does not follow Theme because of matplotlib backend (see

  [#5](https://github.com/partofthething/ha_skyfield/issues/4)

* More (maybe) at [Issues](https://github.com/partofthething/ha_skyfield/issues)
