Toggling between light brightness with single switch (button)

Configuration
1

Hi,

Can someone help me set up my switch to cycle between brightness settings on my light? I’m trying to set it up so that upon a button push, the system will check the brightness state and based on that setting go up or down to the next brightness setting.

I found this link on Reddit https://www.reddit.com/r/homeassistant/comments/551iu1/help_ifthen_statements_in_scripts_time_variable/ that looks like it does what I want but it’s based on time instead of the light brightness. Here’s a snippit.

    data_template:
      brightness: >
        {% if (float(as_timestamp(now)) > 6) and (float(as_timestamp(now)) < 8) %}
          254
        {% elif (float(as_timestamp(now)) > 8) and (float(as_timestamp(now)) < 17) %}
          0
        {% elif (float(as_timestamp(now)) > 17) and (float(as_timestamp(now)) < 21) %}
          180
        {% else %}
          120
        {% endif %}
