Integrating electricity meters with Home Assistant: Simple instructions and tips

You've bought a power meter and now want to seamlessly integrate it into your Home Assistant? Great idea! In this article, I'll show you step-by-step how to do it with ease. You can find the video tutorial at the end of the article or directly on YouTube.

Before you begin, please ensure that your energy meter (Tasmota device) is already connected to the internet. You will need the local IP address of both the energy meter and your Home Assistant system. If you don't know your Home Assistant's local IP address, simply install the handy " Local IP " extension from the Home Assistant Store – this will help you find it quickly.
