Need some help and its probably simple but i’m missing something. This is my first real forray into templating even though iv’e been using HASS for years.
I have a template sensor that counts the number of active motion sensors. However it outputs it as a string.
"{{ expand('binary_sensor.internal_motion') | selectattr('state', 'eq', 'on') | list | count }}"
I am trying to convert it to a number, so that when the number increases i can trigger a counter.
Probably better ways to do it, but this is very simple 
{{(expand('binary_sensor.bedroom_heating_calibrated') | selectattr('state', 'eq', 'on') | list | count) | float}}
But count should already give you an int to my understanding and not a string. Any chance that your wrapping in quotes is causing the conversion to string?
Show the rest of your template sensor config.
Do you have a unit_of_measurement defined?
State values are always strings. However entities with a unit are treated as numeric.
Dimitri Solved it.
Heres the template:
{{(expand('binary_sensor.internal_motion') | selectattr('state', 'eq', 'on') | list | count) | int}}
