Hello,
I tried to track my electricity consumption in Home Assistant, which I only set up yesterday and am still a complete beginner with. For this, I used the Bosch light switches and the Bosch smart plug for the washing machine as a test. Depending on where I look at the consumption data, different values are shown. Additionally, in the energy monitor, the electricity consumption is much too low, even though I set it to 2024.
Here is the second image, and these energy consumption figures are likely correct (the smart home components have been only been in operation for about 2 months):
When you dont want to make an extra template sensor to sum them up, you can add everyone of them to the grid consumption. But if you plan to add total measurements later like a smart meter reader and want to keep the old statistics, you should use a template.
