Rain (DWD)

This use the hacs integration DWD Precipitation Forecast

When it rains in the next two hours, from a DWD precipitation forecast sensor in Home Assistant: the icon in a circle that turns blue while it rains or will within the hour, a sentence such as "In 25 min. it rains for 20 min." or "No rain in the next two hours", the rain now in mm/h, and under it the forecast of the next two hours as bars (light rain blue, a downpour purple).

Set up

1. Have a DWD precipitation forecast sensor in Home Assistant whose attributes are next_start, next_end, next_length (minutes) and forecast (a time and a rain rate in mm/h for every five minutes), such as sensor.dwd_precipitation_forecast_home. Its state is the rain now.
2. In Tessera, open Plugins, Add with a link, and paste the link of this repository. Add the plugin to a screen; the screen builds.
3. In Layout, place the Rain tile (2 x 1 or wider) and choose the sensor in its inspector. Only sensors with a forecast are offered.

Options

• Show the chart: the bars under the words, where the tile has room for them.
• Forecast step: the minutes between two values of the forecast, 5 for the DWD nowcast.

Good to know

• The tile counts down on the screen's own clock; the sensor brings a new forecast every five minutes.
• The chart starts at the first value of the forecast, which the sensor keeps at now.
• It uses no service of its own: everything comes from the sensor in Home Assistant.
