Update rate for a sensor imported into an esp for display

ESPHome
1

morning all.
so i have an esp with a display, that is showing the current power usage
this info is retrieved from home assistant and coming from another esp using a pulse meter which i believe updates the value on each pulse.
is there a way to retrieve this value at a set interval?
ie every minute?
the sensor code on the display unit is as follows

  - platform: homeassistant
    id: elec_usage
    entity_id: sensor.electricity_usage_2
    internal: false

  - platform: homeassistant
    id: elec_cost
    entity_id: sensor.dollarstodaydig
    internal: false

and

display:
  - platform: ssd1306_i2c
    model: "SSD1306 128x64"
#    reset_pin: D0
    address: 0x3C
    lambda: |-
      it.printf(64, 0, id(my_font), TextAlign::TOP_CENTER, "Smart Display");
      it.strftime(0, 20, id(my_font), TextAlign::BASELINE_LEFT, "%H:%M", id(esptime).now());      
    
        it.printf(0, 30, id(my_font), TextAlign::BASELINE_LEFT ,"power usage %.2f KW",  id(elec_usage).state);

        it.printf(0, 40, id(my_font), TextAlign::BASELINE_LEFT ,"power cost $%.2f", id(elec_cost).state);

        it.printf(0, 50, id(my_font), TextAlign::BASELINE_LEFT ,"Battery Level %.0f", id(wemos18650oledbattery).state);

i tried adding an update interval to the first section of code but thats not valid for a home assistant sensor…
do i need to like create a dummy sensor that updates itself to the pulse meter value once a minute and use that in the display module?

Is it updating too often or what is the issue?
As far as I know it should update when it updates in HA

yeah, thats the problem… it sends an update every time the meter “ticks”
i would want it to only be updated like once a minute

I think it’s possible to limit it in ESP-Home, but I would do it in HA since that will make less wifi traffic.

If you throttle in ESP-Home then it will still need to send every value to the display but discard most.

A template sensor reacting on sensor.time is probably the easiest.

I’m still in bed so I have a hard time giving a proper answer now

nah you pretty much answered my question thnx heaps man
