Using a PredAi sensor attribute value into a HA Automation

[mlduncombe]

I couldn't see a Predai discussion so will ask here instead.

I have been playing with Predai with battery SoC and the following returns the right value when I test it in HA Developer Tools/Template as per the screenshot. Its picking up the predicted state of charge at 23:30 from the attribute results of my Predai sensor. I've set the predai config so as only to have a single 23:20 attribute value.

      {% set results = state_attr('sensor.solax_battery_capacity_prediction', 'results') %}
      {% set target_time = now().replace(hour=23, minute=30, second=0, microsecond=0).timestamp() * 1000 %}
      {% set values = results | dictsort %}
      {% for key, value in values %}
        {% set date = as_timestamp(key) * 1000 %}
        {% if date == target_time %}
          {{ value }}
        {% endif %}
      {% endfor %}
      {{ "unknown" }}

Does anyone know how to take that value and put it into a HA sensor or a number helper that I can use with an automation?

I've tried creating a template sensor but have a feeling having the now() in configuration.yaml isnt a great idea.

Cheers
