Hi Juan,
You can go to the product page on our own website, select "User Manual" and download it. Please scroll the download file and you can find it in Spanish version. https://www.netrohome.com/en/shop/plans/1
Thanks,

Sorry currently we do not have the Spark User Manual in spanish. We will have it in Spanish version in the future.
Thanks,
