Home Assistant Jinja 2 Templating to announce some inside Temperatures

Back to README

This process is fairly simple. We don't need to iterate over arrays or anything like that unless we want to get complicated.

For my use case and for the YouTube Video, I chose to read out the temperatures in 4 rooms: This table shows the rooms and the sensor ID's I chose, your smart home will differ.

Dining Room	sensor.temperature_dining	Aqara Temperature and Humidity Sensor
Lounge Room	sensor.lounge_ac_inside_temperature	Temperature Sensor built into my Loungeroom Air Conditioner
Office	sensor.temperature_office	Aqara Temperature and Humidity Sensor
Master Bedroom	sensor.master_bedroom_purifier_temperature	Temp and Humidity Sensor built into my XiaoMi Air Purifier

You should choose the data points that matter the most to you. You can add humidity data if you want

The code to announce the states.

Inside it's currently {{ states('sensor.temperature_dining') }} °C in the Dining Room, 
{{ states('sensor.lounge_ac_inside_temperature') }} °C in the Lounge, 
{{ states('sensor.temperature_office')}} °C in the office,
and {{ states('sensor.master_bedroom_purifier_temperature') }} °C in the Master Bedroom.

But there's a better way!

We're going to crate an Array of Dictionaries, and iterate through the array.
The Dictionary Key is the entity_id of the temperature sensor in Home Assistant.
The Dictionary Value is the Name of the room we want our TTS engine to say.
For the TTS to sound more 'natural' I've added ", and" to the name of the second last item in the array

{% set inside_temps = { 
    'sensor.temperature_dining': 'Dining Room',
    'sensor.lounge_ac_inside_temperature': 'Lounge Room',
    'sensor.temperature_office': 'Office, and',
    'sensor.master_bedroom_purifier_temperature': 'Master Bedroom'

} %}

Inside it's currently 
{% for sensor, room in inside_temps.items() %}
    {{ states(sensor) }} °C in the {{ room }}
{% endfor %}

And in a script:

alias: Announce Inside Temperatures
  sequence:
  - service: notify.alexa_media
    data:
      message: >_
    {% set inside_temps = { 
        'sensor.temperature_dining': 'Dining Room',
        'sensor.lounge_ac_inside_temperature': 'Lounge Room',
        'sensor.temperature_office': 'Office, and',
        'sensor.master_bedroom_purifier_temperature': 'Master Bedroom'

    } %}

    Inside it's currently 
    {% for sensor, room in inside_temps.items() %}
        {{ states(sensor) }} °C in the {{ room }}
    {% endfor %}
