Display a sensor's value only in a given time period

Hi,

I’d like to display a specific sensor on my ESP32 only in the summertime.
I have a time_homeassistant sensor and I can display the current date with

it.strftime(110, 122, id(openSansBold_font),TextAlign::BOTTOM_LEFT, "%d.%m.%y", id(time_homeassistant).now());

How would I check in this example if %m is <3 and >9 (so, between October and February?

Did you find the time functions here? That should get you a bit further along.

You might be better off locating the check in a binary sensor “is_summer” and then working with that.

Thanks for the hint, so I’d think about something like:

auto month = id(sntp_time).now().month

I fail to understand if this is the correct syntax for obtaining the month and how to check the returned value…sorry, absolutely new to ESP32 and not an IT pro…

This should be close.

You can test by changing .month() to .second()

binary_sensor:
  - platform: template
    id: its_summertime
    name: Its Summer Time 
    lambda: |-
      return
      id(time_homeassistant).now().month <3  &&
      id(time_homeassistant).now().month >9
      ;
      
display:
  - platform: ...
    # ...
    lambda: |-
        if (id(its_summertime).state) {
          it.strftime(110, 122, id(openSansBold_font),TextAlign::BOTTOM_LEFT, "%d.%m.%y", id(time_homeassistant).now());
        }
