AT4PW 100A Tuya WiFi Din Rail Smart Switch Remote Control AC 220V 110V Digital Power Energy Volt Amp Kwh Frequency Factor Meter

Only thing I'd like is to turn off the sleep feature. I guess it's there to cut down processor usage but I love the main screen

Software is easy to use

Funciona muy bien, ojo tener en cuenta, que para medir la energía de unos páneles solares, se debe poner al revés, o sea, poner IN. hacia la casa, y el OUT a los páneles, o si no, no prende, necesita energía y la tiene que tomar de la casa.

Although I have a Sense power monitor, I needed to be more confident that the actual use by my old freezer was as accurate as it could be. I got this unit and set up a plug and outlet to monitor specific appliance use. I've only used it for a day, but so far, so good. I also got a plastic enclosure for it from Amazon. I plan to get another unit to monitor my HVAC system. I like the Tuya app compatibility, but I wish the app were more complete. The price is great, and it was easy to wire.

This is a cool device but it lacks one serious feature that I would think most people on unreliable grids could really benefit from. The cheaper units have this feature and it seems like it probably could be added in a future software update. The unit does have a return delay timer for over voltage detect but not on under voltage detect or no voltage. Basically when the power goes out, I want the timer to delay turning the power back on for say 15 seconds to prevent quick off and ons that damage fridges. It also allows the grid to stabilize before connecting. I ended up disconnecting this and going to my old low voltage cut out switch for this reason.

Amazing idea for tracking ur energy usage and onn off from anywhereThere is a little lags while using the a mobile app but over all , i love it

I bought a device like this, I loved the first one, then I bought another one from the same seller and I noticed that the setting (dp_reporting_unterval) equal to 1 second is not staying fixed, it returns to 60 seconds. The seller please tell me how I can resolve this situation. The first stays fixed without any problem but the second every time I enter within a reasonable time it comes back and sets itself to 60 seconds.

I am happy with it. Big screen easy read. So far I am happy when bought it.

Fácil de instalar, números en pantalla grandes para lectura, interfaz a través de app "tuya" muy completa con gráficas de consumo y se puede poner en ceros las veces que se necesite.
