Convert MQTT sensor value

Hi all,

I do have a sensor which gets its data from MQTT:

  - platform: mqtt
    name: "Espressomaschine Countdown"
    state_topic: "Homey/Status_Espressomaschine_Countdown"

However the value is in seconds. Is there any way to convert it to minutes, and if yes, how? :slight_smile:
