Adding a temperature trend sensor

Configuration
1

Hi,

I am trying to add a trend sensor to show if the temperature outside is getting hotter or colder (eventually I want to use this to open of close my curtains).

Initially I tried creating this in the UI, but TBH this confused me, and since there did not seem to be anyway to view the yaml in this editor I instead tried to add it to the configuration.yaml.

Following the instructions here (https://www.home-assistant.io/integrations/trend) I copied the example at the bottom to my config file, and changed it to look at my temperature senor entity sensor.outside_front_sensor_temperature

i.e.

binary_sensor:
  - platform: trend
    sensors:
      temp_falling:
        entity_id: sensor.outside_front_sensor_temperature
        unique_id: outside_temp_falling_trend
        sample_duration: 7200
        max_samples: 120
        min_samples: 20
        min_gradient: -0.0008
        device_class: cold

      temp_rising:
        entity_id: sensor.outside_front_sensor_temperature
        unique_id: outside_temp_rising_trend
        sample_duration: 7200
        max_samples: 120
        min_samples: 20
        min_gradient: 0.0008
        device_class: heat

I checked the config in developer tools and reloaded the yaml, but I can’t see how to add outside_temp_falling_trend or outside_temp_rising_trend to a dashboard to see if they are working. And they do not appear in my entity or helper list.

I am sure I am misunderstanding something basic.
Can anyone help me out?

If this is the fist time you have used the YAML binary sensor integration you need to restart Home Assistant for it to be loaded.

The first time you use any new YAMl integration you need to restart. Then after that you can use reload.

Fantastic :slight_smile:
Thanks.
I knew it would be something simple I didn’t understand.
I’d reloaded the yaml, but hadn’t restarted HA. :+1:
