Numeric Template Sensor Value Not Available in Any LoveLace Card

Configuration
1

Hi,

I have defined template to read the 30 minute electricity export values over defined time. It use a known and proven HACS sensor(sensor.agile_export_rate) gets dict of todays 30 mins prices. The sorts them and determines if any the export prices are above my target profit. input_number.target_profit_am

Within the Developer tools it works perfectly and returns the count as expected and there are no errors generated etc.

However, when use the sensor in any Lovelace card i get “Unavailable” but, if I use the “States” tool and set a value manually it displays correctly. I had thought that the line {{ {{ ns.count }} would return the value I see the Developer tool.

I share the code in the hope someone can show me the errors of the ways…

    {% set rates_today = state_attr(‘sensor.agile_export_rate’, ‘rates_today’) %}

    {% set sorted_rates_today = dict((rates_today.items() | list)[52:102]) | dictsort %}
    {% if sorted_rates_today | count > 0 %}
