Show pressure 3h ago

Configuration
1

Hello,

I would like to show the relative pressure I get from my ecowitt weather station and show it in combination with pressure 3h ago in ring-tile card.
The sql query from the ring-tile card readme does not work for me.
I havent found an other solution so far. Maybe s.b has done it and can give me a hint.

Thank you so far,
Stefan

Create an SQL sensor to pull the previous value from your database.

There are some useful examples in the documentation: https://www.home-assistant.io/integrations/sql/#state-of-an-entity-x-time-ago
