Home Assistant Battery Warning Card Using Auto-entities

In this video we show how to create a Home Assistant battery warning card using auto-entities to add to a dashboard

Auto-entities is a very useful plugin you can use in Home Assistant to only display entities that meet a certain criteria

So for example, you can create a card using auto-entities which will only display devices with low battery levels

Once you replace or re-charge those batteries, they disappear from the list automatically

This seems better than getting an instant notification because you may not have a spare battery at the time or be nearby to replace the battery immediately making you more likely to forget

Whereas with this card, a regular check of the dashboard serves as a constant reminder until the battery is replaced

Steps Taken
1) Install auto-entities using HACS
This is an easier method and HACS will also tell you when new upgrades are available and install them

2) Create a Dashboard
The default dashboard is more for admin purposes, so create a new one that you can customise

3) Update Lovelace
The Lovelace GUI needs to know where to find the plugin
To do that you need to be in advanced mode and then add the auto-entities URL as a resource
/hacsfiles/lovelace-auto-entities/auto-entities.js

4) Control Dashboard
To edit and customise a new dashboard you have to take control of it
This is a one off choice and you can choose to turn this into a blank dashboard, rather than contain everything the overview dashboard contains and then have to delete cards

5) Battery Warning Example
Add an auto-entities card to the dashboard
After that configure it with the visual editor or the code editor
In this example we paste in some example code Brian Coke provided in a forum which is great for only warning of devices that have a low battery level

See pinned comment for example code
