FAQ - How to create a number helper
Required: We use number helpers to record the start and end kWh of your current sensor. This must be a completely independent number helper. One for the start and one for the end. Below shows you how to create a number helper and the settings.
Optional: We also use a number helper for your electricity rate, as you may use it in more than one automation. If your rate changes, you can adjust all your automatons in one location through the UI. If you are not using the cost feature then you don’t need to create this helper.
How to create a number helper:
-
Go to Settings > Devices & Services > click on the “Helpers” tab / click “+ CREATE HELPER” and select “Number”.
-
Enter in the name you would like to call your number helper and select an icon if you like.
- Change the min / max = For start and end number helpers you have to set the max to a higer value than you will ever have. I recommend setting it to 10 million (10,000,000 that is 7 zeros). If you need to set it higher then just keep adding zeros. For electricity rate see below for the settings I used.
- Display mode = I am not using it as a slider in the UI so I selected ‘Input field’.
- Step size = recommend you set it to ‘0.01’
-
Your done. Now just add the number helper into your automation correct input.
Below is an example of my Electricity Rate number helper.
