Ewelink WiFi Wireless Smart Relay Module USB 5v 4 Channel Inching Self-Lock Latched Dry Contact Remote Switch for Access Control, Garage Door,Home Automation, Compatible with Alexa Google Home

It has more than 800 hours of continuous work and continues to work perfectly. It has a very good price-quality ratio.

This relay works great for my furnace blower. Allows me to set any fan on settings I need.

This was great set up was easy and it works as advertised.

Installed outside the house to control led strips by the pool. Work like a charm!I just ordered another unit.

Instructions are horribleRemote appears to be Wifi only - not RFRemote has no pairing button to connect to wifi

Does what it is supposed to do

instructions in the box is so small I cannot read it. I went back to the website to look at the instructions. Even with a magnifying glass very hard to read.

1. With so many apps available, it is preferred that this unit be allowed to be used with other apps like smart life.2. It has been observed that the relay turns off by itself3. It is easy to install but more documentation is needed to take advantage of the meaning of the LEDs and switch operations.4. Works well with Alexa, but concerned about relay turning off -- could be an indication that the relay driver cannot handle prolonged "relay on"

tiene 2 modos de carga, el que tenga salidas NO / NC lo hacen más funcional y no necesita ajustes en la app e-we link

Aunque no muy buena documentación como la típica de estos productos, el producto se programó fácilmente y se enlazó muy bien a la red, la operación resultó muy buena y a la fecha no ha fallado, yo la tengo para abrir una puerta eléctrica y lo hago con Alexa sin problema, sería muy recomendable que tuviera una carcaza, tiene las medidas idénticas que las de un switch de otra marca y utilicé la cubierta de plástico para poderla instalar con alguna protección.
