Example 3: Environment sensors with history

Visualization of some environment sensors.

AmoebeLabs Swiss Army Knife Custom Card Example 3 - Sensors

Visualization

The card is build using the following tools:

  • A rectangle with a large top-right corner radius with a circle on top of that. The Neumorphic shadow filter 'morphs' them as looking as a single object
  • State and unit of measurement
  • The name of the entity
  • A barchart showing the trend over de last 24 hours using a light to dark orange gradient setting as colorstop

Interactions

  • All tools support by default the "more-info" dialog once clicked.

Used Home Assistant Integrations

  • Aqara Zigbee sensors with temperature, humidity and pressure data

I use [zigbee2mqtt][zigbee2mqtt-url] for the Zigbee sensors and lights. Zigbee2mqtt can be used either as docker container or [Home Assistant Add-on][zigbee2mqtt-addon-url] combined with the MQTT integration

How to make it work in your own installation

All cards

Required Home Assistant Integrations
The visualization is build on temperature, humidity and lux entities. It does not depend on any specific integration.

Required Home Assistant Entity Changes
You can replace the existing temperature, humidity and lux entities with any sensor entity.

View and Card Configuration

Lovelace view

file location included from
view-sake3.yml /lovelace/views sak-examples-dashboard.yaml

This example uses decluttering and SAK templates for the card

Both SAK templates and Decluttering templates are used to display the cards. This view is therefore as compact and easy to read as possible and is a good example of re-use.

Decluttering templates

Excerpt of the header configuration...

  • The header_template is used for displaying the header sak card

SAK templates

The following templates are defined in the /lovelace/sak_templates/sak-templates.yaml file:

  • The header is the template used for the header texts
  • The toolset_sensor_history is used for the sensor cards.

Remarks

This view is an excellent example of how to pass variables from a decluttering to a SAK template

The sak_sensor_history_template_nm_tpl decluttering template and toolset_sensor_history SAK template show how these templates can work together in passing variables from one template to the other.

Excerpt of decluttering template for passing variables from a decluttering to a SAK template

The variables passed to the decluttering template are passed directly to the SAK template. In this case it is the color range for the barchart.
