Include Average Sea Level Pressure in Pressure Lovelace Cards

I would like to include a horizontal line showing the average sea level pressure in my pressure lovelace cards. Thus I am able to see whether we are in a high or low pressure weather condition.

One possible solution might be a sensor showing a static value, but I haven’t found a way on how to configure such a sensor reading. How am I able to achieve it?

Is there any other possibility than a fixed value seonsor?

looks like openweathermap does it

just need a way to add the integration

The openweathermap shows the pressure as the actual value as well as normalized to the sea level. This isn’t what I am searching for. I would like to add a fixed value of the normal pressure at my level. Think about it as a sensor always replying the 1013 hPa value for sea level. Thus I would be able to see whether my current sensor data is showing a high or low pressure condition.
