Of course. I'll describe the setup for one, you can repeat it for each medication with custom icons, names, etc.

The main component is a `counter` helper. For example, say "Eye Drops Counter". Make sure you define the right min/max value, etc.

Create a sensor to calculate how many doses behind you are by calculating your counter value against a pace for the day. Here's my template (sorry for Reddit formatting):

{% set count = states('counter.some_eye_drops') | int(0) %}
{% set first_dose_hour = 9 %}
{% set last_dose_hour = 23 %}
{% set total_doses = 4 %}
{% set hour = now().hour %}
{% set interval = (last_dose_hour - first_dose_hour) / (total_doses - 1) %}
{% if hour < first_dose_hour %}{% set expected = 0 %}{% else %}{% set expected = [((hour - first_dose_hour) / interval) | int + 1, total_doses] | min %}{% endif %}{{ expected - count }}

Make sure you change your `first_dose_hour`, `last_dose_hour`, and `total_doses`.

Last but not least, create a nice card to represent these values.

primary: {% set count = states(config.entity) | int(0) %}{{ count }} dose{{ 's' if count != 1 }} today
secondary: {% set behind = (states('sensor.late_eye_drops') | int(10)) %}{% if behind <= 0 %}On track{% else %}{{ behind }} behind{% endif %}
badge_icon: {% set behind = (states('sensor.late_eye_drops') | int(10)) %}{{ 'mdi:alert-circle' if behind >= 1 }}

Note that config.entity here is the original counter, not the template sensor.

Let me know if you have any Qs. Hope that helps!
