Hi Beatriz,

There are two possible approaches to your question, depending on your specific needs.

The explanation from my colleague Jef applies well to your case. You’ll want to start with a value-based search on the TM_month* tag that corresponds to your timezone. After that, you can apply the necessary calculation — in your case, likely an interval-based calculation on the energy consumption tag. Once that’s done, you can open Event Analytics to explore different visualizations of your results.

If you’d like to persist the calculated values, you can save them directly to context item fields, as outlined in this post.

Alternatively, if you want the result available as a tag, you can use the Custom Calculations functionality (please note this is intended for expert users). Depending on your use case, you might create a block aggregate or an incrementing totalizer. More details are available in our GitHub.

If you have any further questions, feel free to reach out!

Best regards,

Frederik
