Apparently you're still missing something 😉

Hello Nicolaas!

after reading your reply I realised how I failed to read the comments in your code which are all I needed.
Thank you for being patient and just pointing me to what was in front of my eyes the whole time.

I got it working. Many thanks!

If I may ask one more thing. It is trivial and doesn't affect the functionality, only my OCD.

Reading the output of the sensor I see it doesn't convert to my local time

I did add my timezone:

time:
  - platform: homeassistant
    id: homeassistant_time
    timezone: "Europe/London"
    on_time_sync:
      - component.update: sensor_uptime_timestamp

sensor:
  # Uptime Sensor
  - platform: uptime
    name: Uptime Sensor
    id: sensor_uptime
    internal: true
  
  # Uptime timestamp
  - platform: template
    id: sensor_uptime_timestamp
    name: "${short_name} - Uptime"
    device_class: "timestamp"
    accuracy_decimals: 0
    update_interval: never
    lambda: |-
      static float timestamp = (
        id(homeassistant_time).utcnow().timestamp - id(sensor_uptime).state
      );
      return timestamp;
