Last seen in seconds convert to Minutes ago , Hours ago

Configuration
1

Hi,

I got sensors and gives the value in seconds for last seen. I
With zigbee2tasmota, the value for last seen is triggered and send over mqtt to homeassistant.

How do I convert the seconds into (for example 30 sec ago, and more as 60 seconds, 1 min ago, more than 60m , 1 hour ago), just like the last changed value works in homeassistant

I get the value in seconds with this

- platform: mqtt
  name: "Rookmelder lastseen"
  state_topic: "tele/z2t/6F40/SENSOR"
  value_template: >
    {% if '0x6F40' in value_json.ZbReceived and 'LastSeen' in value_json.ZbReceived['0x6F40'] %}
      {{ value_json.ZbReceived['0x6F40'].LastSeen }}
    {% else %}
      {{ states('sensor.rookmelder_lastseen') }}
    {% endif %}
  unit_of_measurement: "s" 
  availability_topic: "tele/z2t/LWT"
  payload_available: "Online"
  payload_not_available: "Offline"

I think this is the solution

          {% set uptime = states.sensor.rookmelder_lastseen.state | int %}
          {% set Hours = (uptime / 3600) | int %}
          {%- if Hours > 0 -%}
              {{ Hours }} Hours, {{ (uptime - (Hours * 3600)) | int | timestamp_custom('%-M Minutes', false) }}
          {%- else -%}
            {{ uptime | int | timestamp_custom('%-M Minutes', false) }}
          {%- endif -%}
