eMylo Smart WiFi Light Switch Wireless Relay Switch Module Remote Control Home Automation Timers Compatible with Alexa Echo Google Home iPhone Android App 2 Packs

I am not quite sure what they mean warmth and sheerness that they ask to you to evaluate/rate. ??? The reason I like them is that they are an easy unit to use and wire into a device that needs control, and can be controlled by Alexa or a phone very easily. Such as... I added a fan in the garage above the garage door opener to control heat movement from an electric garage heater I added. The pull switch would have been a nuisance. I mounted one of these babies in the cord set going to the garage door opener outlet and now I can say Alexa turn on garage fan anywhere in the house. So cool. I have also used these to make short Wifi extension cords. These are easy to make. You take a flat plug extension cord with two wires, (unplugged of course), cut it, cut it to length, strip 3/8 or so on each of the four wire ends and plug the stripped wires into the four connector blocks provided. Make sure you have the wall side of the cord with the plug go into the IN side of the unit and the 1, 2 or 3 outlet side of the cord go into the OUT side of the unit. You now have a Wifi extension cord. Why you ask? You could use a Wifi module and put it into the outlet and plug your device into it. But on some circumstances where you have furniture that needs to fit up against a wall, the extra module and plug pushes the furniture away from the wall. This works very nicely.

Easily set up and reliable. Works perfectly as advertised.

as described, would buy again

Gave them away. Get some that have a WiFi search button. Ridiculous instructions.

Good for low power applications.

Surprising easy to set up with their app.

I used this to control a 2 speed 2 HP pool pump in conjunction with a 30A relay (https://www.amazon.com/Tnisesm-Mounting-Connect-Terminals-NT90-AC120V-10X/dp/B087G6D24G?ref_=ast_sto_dp&th=1) This switch was placed in a thick plastic junction box outdoors 100 ft from the access point. I made sure my android phone was on the 2.4 GHz wireless network when I brought up the SmartLife app. It found the device immediately and added it to my home WiFi network. The outputs from the WiFi switch drives the relay that turns the pump from low speed to high speed. I added the device to Google Home and now can voice control and schedule when the high speed on the pump (for cleaning the pool) runs and for how long.

Is it possible to open the garage gate ?

Ive been using these for years. For years they were always the hardest device to get back online after a router reboot. I ended up changing them out for TPLing / Kasa devices.

Im not good at downloading apps and getting them to work, but, I did it and it was relatively easy. Works great with Alexa as well.
