Add manual update method also to triggered template sensors

[verjager]

Sensors can be forced to update manually with:

  - service: homeassistant.update_entity
    data: {}
    target:
       entity_id: sensor.p2000_ambulance

However this does not apply to template sensors:

NotImplementedError: Update method not implemented

Could this be added?

So we could run a automation with triggers and conditions to update in specific cases?

You can already accomplish this by using an Event trigger with a custom event

Indeed, this is what I ended up with. Nevertheless it would be a nice-to-have, which improves consistency with other sensors.

My original use-case was this:

Conditions in Trigger-based Template Sensors

I support this request. My use-case is to split a sensor into multiple sensors by means of a number of derived template sensors. This limits the number of external calls. # Template triggered P2000 sensors - trigger: - platform: template value_template: "{{ 'Ambulancediensten' in state_attr('sensor.p2000_zhz', 'discipline') }}" sensor: - unique_id: "p2000_ambulance" name: "P2000 Ambulance" state: "{{ states('sensor.p2000_zhz') }}" a…

More than in automations this would be useful during testing and debugging of entities. At the moment the fastest method is to create a Helper button, which imho doesn’t seem like the most elegant thing in the world. (+1)
