Specific automation evoke z-wave storm rx/tx messages

Configuration

So I want to make one rule for all day periods for my climate system. From 8am to 5pm - 81f, for 5pm to 10 - 78f and so on.

- id: 'honor_daytime_temp'
  alias: 'Honor Daytime Temp'
  trigger:
  - platform: time
    hours: '/1'
    minutes: 2
  action:
  - service: climate.set_temperature
    data_template:
      entity_id: climate.2gig_technologies_ct101_thermostat_iris_cooling_1
#      value: >
      temperature: >
        {% if now().hour >= 8 and now().hour < 17 %}
          {{ 81 | float }}
        {%-elif now().hour >= 17 and now().hour < 22 %}
          {{ 78 | float }}
        {%-elif now().hour >= 22 and now().hour < 5 %}
          {{ 76 | float }}
        {%-elif now().hour >= 5 %}
          {{ 78 | float }}
        {% else %}
          {{ 80 | float }}
        {% endif %}

It looks fine for me. Every 1 hour on 2nd minute we check current hour and if elseif we send command to CT101 unit.

But, when I enable this automation I get storm of messages to z-wave unit (around 1500 in half hour), then my device become dead (literally, it stops working at all, not just z-wave).

How do you think why? Maybe there is more nice solution to do my task without making bunch of automatons?

Thx!

Ok, I added notifier to action and get bunch of messages.

Turns out it sends packets whole minute. I need to add seconds. But, it will send whole second either.

How can I limit actions to 1 action per time?

From the official documentation:

“Remember that if you are using matching to include both minutes and seconds. Without seconds, your automation will trigger 60 times during the matching minute.”
