Question: use now() or sensor.date

Nice trick, this sensor.

I was just wondering. Wouldn’t using now() be evaluating every minute, and using the sensor.date entity be evaluating just once a day?

https://github.com/BeardedTinker/Home-Assistant_Config/blob/0ff7960b353db79270fb2d3f0c8d2efd45e4e25f/entities/sensors/today.yaml#L10

Another value_template could be:

value_template: >
  {% set w = strptime(states('sensor.date'), '%Y-%m-%d').strftime('%w') | int %}
  {{['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'][w]}}

Not as clean but less resource consuming.

Sorry for this - obviously hiccup from my side - I did write a very long response, but probably never hit submit/comment button 😃

Yes, you are correct about now() vs sensor.date I will be implementing your suggestion for using sensor.date.

At one point I had a good reason to keep it like this, but that is now gone 😃

I should probably go through all of the code and track other time/date usage in there.
