Te deja ver el consumo actual de toda la casa y el acumulado desde una fecha.
No estoy acostumbrado a usar estos aparatos pero anduve trasteando en el contador y es bastante sencillo de colocar para una persona sin conocimientos previos. Te lo pone en el manual, simplemente pasar uno de los cables por dentro y el otro al aparato anterior. Lo veo muy util y comodo. Las lecturas que te da son útiles y tiene un botón para que te marque desde cuando a cuando estas gastando y cuanto. Pues para medir si la compañía eléctrica te estas cobrando bien los kilovatios. No tengo ni idea lo que puede durar, pero para una primera incursión esta bien. Si después de un tiempo la espicha pues son 30 Euros que se van, pero siempre estas a tiempo de comprar uno nuevo y bueno si quieres, Según he leído los hay de marcas potentes pero claro nos vamos a much apasta siempre mas de 100 Euros. Así que es una versión low cost que no esta nada mal.

An excellent tool for diagnosing and detecting abnormal consumptions
I have installed three units (one per each phase) as a replacement for old analogic amperemeters. Easy installation and works fine providing good information allowing me to check the consumptions of every distribution line at home by switching on and off each individual circuit. Unbalanced phases can be easily recognized in the display numbers if any. I found it quite useful for detecting a switched off LED lights circuit (30 lamps) that was permanently consuming more than 200W. Since the lamps were dimmed to a minimum (and not totally switched off) I was not aware of the consumption amount due to that fact. The reduction in my electricity bill will rapidly pay the investment made in these units and in two new switches. I include photos of the replaced analogic amperemeters and of the new units installed.
