Yeah sure, I’ve built a quick example:
-
You need this installed GitHub - iantrich/config-template-card: 📝 Templatable Lovelace Configurations - have a read through if your not familiar to try and get the concept in your head.
-
Create an input select helper with the values you want to use in your graph for the periods e.g. 1h, 2h, 1d etc (this will need to correspond to the expected values for whatever your using to graph – I’m using Apex Charts in this one)
Once you’ve got these you can then go to your dashboard and
- Create an entity card with the input_select helper you made. This will then allow you to change the period from the dashboard:
type: entities
entities:
- entity: input_select.period
- Create a config-template-card referencing the input_select helper you created as its variables and entities to watch, and within this include your graph card (apex charts in my case) - for the period (graph_span in my example) reference the variable defined in the config-template-card.
type: custom:config-template-card
variables:
- states['input_select.period'].state
entities:
- input_select.period
card:
type: custom:apexcharts-card
header:
show: true
title: ApexCharts-Card
show_states: true
colorize_states: true
graph_span: ${vars[0]}
series:
- entity: counter.daily_presence
And voila, you will be able to dynamically change the periods of your graphs - let me know how you get on
