How to test service_data output

[mihatsu]

Hi,

I tried to search answer because this must basic thing but I could not find anything. I have many times problems to write service_data line and I don't know how to debug it. How I can call that I see what is the output?

For example how do I see what this service_data output is?

• entities:
  - sensor.garage_temperature_temperature
  state_action:
  - service: floorplan.text_set
  service_data: >-
  ${(entity.state !== undefined) ? Math.round(entity.state * 10) / 10
  + "°" : "unknown"}

It is JavaScript. You could use this to check for syntax errors? (Just remove the $ and curly braces) https://esprima.org/demo/validate.html

Hello. You'er able to console.log this, and return the value itself instead. If you look through my videos (find the links in the tutorial category), you should find a example.

Take a look at:
https://github.com/exetico/Home-Assistant_Attachments-for-YouTube/blob/main/6_Format-time_date.time-entity-from-military-to-AM_PM-in-state_action/case3-final.yaml

If the last part was saved to a variable first, you could console log it before return it:

state_action:
            - service: floorplan.text_set
              service_data:
                text: |
                  > 
                  console.log(entity.state);
                  const dateTimeString = "1970-01-01 " + entity.state // You'll need to provide a date string to new Date()
                  const dateTimeParsed = new Date(dateTimeString); // New date object created here
                  return util.date.strftime('%I:%M %p', dateTimeParsed);

I'm on my phone, so its hard to adjust it properly.

state_action:
            - service: floorplan.text_set
              service_data:
                text: |
                  > 
                  console.log(entity.state);
                  const dateTimeString = "1970-01-01 " + entity.state // You'll need to provide a date string to new Date()
                  const dateTimeParsed = new Date(dateTimeString); // New date object created here
                  const returnValueDebug = util.date.strftime('%I:%M %p', dateTimeParsed);
                  return returnValueDebug;

Now you can open up your inspect tool in your browser, and see the value in the console, every time the code executes.

Also check 18:58 here, if you've not used the Inspect tool before:
