Define variables for friendlyname

[Thuurke]

Is it possible to use some kind of variables in the friendly name?
Maybe a little overdone but I would like to define a variable and give it a text which I could use in multiple friendly names, so when I change it, i have to do it on one place.
I tried !secret but this is nog for friendly names.

We tried, but it’s not going anywhere fast, you could add your vote though.

Friendly_name_template for Binary_sensors

as title, it would be really nice if we could do that: please see: allow for: binary_sensor.low_lux_input: friendly_name_template: > Low lux input - {{ states('input_number.low_lux') }} binary_sensor.high_lux_input: friendly_name_template: > High lux input - {{ states('input_number.high_lux') }} binary_sensor.home_theater_lux_input: friendly_name_template: > Home theater lux input - {{ states('input_number.home_theater_lux') }}
