Simple installation and works great
Perfect for converting a gate or garage motor to wireless! The installation was super simple. Just wire it up, connect it to the Wi-Fi app, and voilà instant wireless control.

Nice and simple tech.
I bought this to control my pellet stove in the winter. Set it to thermostat mode and wired this up instead of the thermostat. Now I can controls my 1990s pellet stove with Alexa. Pretty cool.

Use this to convert your garage door opener into a smart garage door opener
I have used this relay to convert my regular garage door opener into a smart garage door opener. It is very east to use and allows you to control it with your phone. I highly recommend this relay!

Setup using eWeLink worked the first time and was very easy.
This is a review for the KR0548-1CH, the 5-48V DC 1 Channel module. I used this module to control a fireplace in parallel with a wall switch. Connection was to the Normally Open (NO) and Common terminals. There was a picture for the connections but some explanation of the +7 to-48V power port would have been useful. Most important the eWeLink setup was very straight forward and worked the first time. I'd buy again.

Cheap and does not work. Waste of time
I bought 2 of these supposedly smart switches. None of them work. They don’t enter in pairing mode. I feed them with 5v DC. No results. Out of the return window. Just threw $20 down the drain.

Easy to install
Installed on a gate motor, works great, with the wiring diagrams for the boards installation was easy. Instructions are sufficient considering I never did something like that before.

Barato y funcional
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.
