very nice!!!

excellent product, too bad it doesn't display the reactive current and power factor, but the measurement is extremely precise, I also have Shelly products, but for precision there are no comparisons, excellent value for money

Muy útil para ver el consumo

Instalación sencilla en el cuadro eléctrico, basta con ponerle fase y neutro desde otro diferencial y poner la pinza amperimétrica en la acometida.
Se conecta fácil con la App a la Wifi de casa y puedes usarlo en un panel de control de Home Assistant.
Muy útil para ver el consumo en tiempo real y aprender el consumo de los electrodomésticos.

POWCT ne fait pas la différence du sens du courant

Bonjour. La puissance est toujours positive car POWCT ne reconnaît pas le sens du courant malgré la flèche sur la pince. Avec des panneaux photovoltaiques quand il y a sur-production le courant par vers le réseau électrique. Il faudrait visualiser le sens pour activer des scénarios et consommer le surplus. Allez vous faire une mise à jour ? Merci.
English : The measured power is always positive because the product cannot see the direction of the current (forward/backward current).
So I cannot do scenarios when the power goes to the external electrical network, injection to GRID.
When my photovoltaic panels produce more than I consume, I would like to activate other Sonoff products to use my overproduction.
The direction of the arrow on the current transformer is useless.
When will you update?
Competing products do this very well.
Sincerely
Stf FR

We just sent you an email to confirm the problem, please provides us some pictures details of the scenarios you set, so we can double check.

would like this to have some way to activate the relay at a given power setting.. otherwise, I don't understand the point of the relay. It just becomes a measurement device only

We just sent you an email to confirm the problem, please check the email.

Consumption reset

Once installed, everything works except zeroing consumption, it says successful but it doesn't work.
To update firmware?

Thanks for your feedback, for the zero consumption problem, could you kindly provide us some pictures to check the problem?
