Help formatting template sensor output

Configuration
1

Here is a typical output of a sensor I have HA.

Exited (143) 22 hours ago


I want to change the output to remove the numbers in brackets and replace ‘Exited’ with ‘Stopped’. E.g.

Stopped 22 hours ago


I replaced 'Exited' with 'Stopped' easy enough, but I'm having trouble remove the ' (143)' part (the numbers inside the brackets change) 
sensor.docker_pi_hole_uptime:
  value_template: '{{ states.sensor.pi_hole_uptime | replace("Exited", "Stopped") }}'

It looks like I need to use Regex, which I barely know, and searching returned something like this should do it

replace("\([0-9]{3}\)", "")


That doesn’t work, so I’m hoping someone could help getting this formatted how I want :slightly_smiling_face:

try
‘stopped {{ states.sensor.pi_hole_uptime.state.split(")")[1] }}’

way to test it is to go to templates in developers tools and move it around till you get the output you want

Perfect, thanks!

Could you explain what this part is actually doing/means?

split(")")[1]


It will hopefully help me understand it more for things in the future :slightly_smiling_face:

the split, splits/separates the content based on your instruction.
In this case it will look for the ) in your “Exited (143) 22 hours ago” state and the number 1 tells it to show the text to the right.
Zero would show left.
