Please correct me if I am wrong, but is seems I cannot create a simple template helper via the UI.
In my sensor.yaml
I can create
- platform: template
sensors:
octopus_current_rate:
value_template: >
{{(float(states('sensor.octopus_energy_electricity_xxxx_current_rate')) * 100) | round(2) }}
unit_of_measurement: "p/kWh"
It seems I cannot do this via the UI. The ‘Helpers’ want to add all sorts of junk (like step, max, min etc).
