I suspect you don’t understand how the different flow cards (If / And / Then) and logic cards work.

The flow card _ **Maximum temperature kleiner…** _ is a If/When or Trigger card. This card starts this flow when the max. day temperature drops below 18 °C. And only then this card is triggered and the flow is started. So it’s not a condition card (And).  
An _ **ALL** _ card after a trigger card (If/When) never works, please have a look at this [topic](https://community.homey.app/t/faq-advanced-flow-infinite-canvas-infinite-creativity/65145).

What you need is a trigger, that recognizes when you start showering, e.g. a humidity sensor or a switch button. Then turn on ventilator. **And** (condition card) max. day temperature is below 18 °C **then** turn the heater on. The condition card can be a card from the app, but usually logic cards inkl. tags must be used. Perhaps this [support](https://support.homey.app/hc/en-us/articles/4410240765586-Using-Homey-Logic-in-Flows) article will help you to understand it.

If you need further help, please let us know.
