Command line sensor no longer working

Hi, I have some command line sensor calling data from an external website. They worked for around 2 years but now, I thing since 2022.5.x they broke. What I found in the logs was that I need default values for external data if they do not return a number on load. So I changed my sensor to this

- platform: command_line
  name: "Draussen Absolute Luftfeuchtigkeit"
  command: 'curl "https://mydomain.com/luftfeuchte.php?temp={{ state_attr("weather.openweathermap", "temperature")  | float(23)}}&pressure={{ state_attr("weather.openweathermap", "humidity")  | float(64)}}"'
  unit_of_measurement: "g/m³"

I do not get errors anymore but the sensors do not show up anymore in my setup.

Anything I miss that changed?
