Time since HA service start

Configuration
1

Does any one have example of sensor that shows time since last HASS service start?

I have this one :

https://github.com/CCOSTAN/Home-AssistantConfig/blob/master/sensor/hass_stats.yaml

I’m still working to convert the time to time since. I tried using relative_time() but could’t get it to work though. Its a good start though.

There is also code here for processing the date:
https://github.com/CCOSTAN/Home-AssistantConfig/blob/master/sensor/systemmonitor.yaml#L8-L50

I’m reading the date/time of the first line of the logfile and templating the output.

### HA Uptime #########################################################
- platform: command_line
  name: "HA Uptime"
  command: echo "$(($(date +%s) - $(date -d "$(head -n1 /home/homeassi/.homeassistant/home-assistant.log | cut -d' ' -f-2)" +%s)))"
  scan_interval: 60
  value_template: >-
    {% set uptime = value | int %}
    {% set seconds = uptime % 60 %}
    {% set minutes = ((uptime % 3600) / 60) | int %}
    {% set hours = ((uptime % 86400) / 3600) | int %}
    {% set days = (uptime / 86400) | int %}
    {%- if days > 0 -%}
      {%- if days == 1 -%}
        1 day
      {%- else -%}
        {{ days }} days
      {%- endif -%}
      {{ ', ' }}
    {%- endif -%}
    {{ '%02d' % hours }}:{{ '%02d' % minutes }}

Which leads to x day(s) hours:minutes

HI @CCOSTAN.
I was looking on your config today.
Last boot works great.
HA version was also moved to my config.
But your ha_last_restart tied to your automation that fires on homeassistant_start.
I don’t have such automation yet. Right now I don’t see that I need notification on startup. I’m in process of setting up and restart service several times during a day.

Nice idea to read log. I’ll try.
