SQL-sensor not updating

I’m trying to set up a sql sensor that comes from the database phpmyadmin. In phpmyadmin these are my sensors that are logged:

For displaying the humidity I have written the following SQL code:

SELECT * FROM states WHERE entity_id = 'sensor.humidity_2' ORDER BY last_changed DESC LIMIT 1

In phpmyadmin this code works fine and I get the latest updated humidity. In my configuration.yaml file, I placed the following to display the SQL sensor:

When I now request the value of the sensor, I get the following:


This all seems to be good, but when I request the value in phpmyadmin, I get a different value:

Also the sql sensor is not updated anymore and remains 76, even when I restart the hass.

What am I doing wrong here? Or how could I get it working?

Found my error. I forgot to also include the db_url.
