Wierd problem with javascripts and time_offset

[henriknordgren]

Ok, I have a template sensor which outputs an offset like "-24h"

Then in my plotly graph I do this

time_offset: $fn ({ hass }) => hass.states["sensor.offset_hours"].state

It doesnt show anything at all. I have confirmed that plotly can interpret the state by doing this:

 yaxis:
            title: $fn ({ hass }) => hass.states["sensor.offset_hours"].state  

It correctly output -33h or whatever the template is.

Also, I tried this:

time_offset: $fn ({ hass }) => '-33h'

and it worked perfectly with correct values in the graph.

I have spent several hours testing back and forth, and can't figure out why it doesnt work with the offset?

I tried this variant also:

time_offset: ${ states["sensor.offset_hours"].state }

and it doesnt work here, but it works for lots of other properties like:

 entities:
          - entity: ${states['sensor.energy_graph_sensor_name'].state}

It is funny, the problem started when I wanted to subtract a constant from the offset. I did this originally when the offset was just an input_number:

time_offset: ${ parseInt(states["input_number.offset"].state) * 24 + 'h' }

the above worked beautifully, but when I did this:

time_offset: ${ ((parseInt(states["input_number.offset"].state) * 24) -9) + 'h' }

The problems started. Then I moved to a sensor template instead, but still no joy.

I cant seem to figure out why it refuses to work, do please help...

Did you try

time_offset: |
  $ex hass.states["sensor.offset_hours"].state + 'h'

[henriknordgren]

I can't explain it, but doing like this:

$ex hass.states["sensor.offset_hours"].state + 'h' worked. I removed the h from the template, so th template returns an integer, like -10

Thank you! I am very puzzled as to what the difference really is?

Note that the notation is $ex, you were using ${...}
