• Reference

Abstract: use one energy meter (brand IAMMETER) to show how to set the TOU(Time Of Use) billing mode in the Home assistant.

Video tutorial:https://youtu.be/7uTE4NAqF_E

Please note: this is a universal tutorial about setting the time of use billing template in the Home Assistant. It does not ask to use a specific brand of energy meter.

This is the effect of display the TOU(time of use) billing information in the dashboard.

Integrate Energy meter

In this chapter, we use IAMMETER`s energy meter as the example hardware. This tutorial is not related to a specific brand, you can use your own energy meter in your hand.

Add the repository of IAMMETER from the HACS

Click HACS, search "IAMMETER".

Add Energy meter

Setting->"Device & Service"

Add the TOU (Time of Use) billing template from a Yaml file.

click "File editor"

add a new YAML, named "peak.yaml"

Add the following configuration in "peak.yaml"

You can also download the "peak.yaml" from the github here

CHECK CONFIGURATION, RESTART

Configure the Dashboard(optional)

This chapter just gives a dashboard example to show the TOU billing effect. It is not a necessary step for the TOU billing, you can also use your own dashboard to display the TOU effect.
