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

To start with they are current rated so they have limits. These work fine if you completely replace a switch. The overall construction of these is cheaply made. One of the four pack I received the end cover was broken off. Wires are real short and the provided connectors in my opinion are junk. Might work nice on stranded 14 but what house wire is like that. The size will fit in electrical box but as stated replacing a switch and blank cover. What I hated the most about these is unlike smart bulbs they do not stay in last state / position. As a comparison you can use a smart bulb and still operate with a light switch. So during the day you can enter / leave a room and operate the lights on a switch. When you go away you can leave switch on and operate through smart life app. With these relays they will remain on Wi-Fi in app as the lights do. However you have to leave switch on and only operates on Wi-Fi. It will not hold the state it was in. It is literally a switch. Not very useful in comparison to bulbs. So really depends on what you want to achieve. This is not for some home do it yourself. Make no mistake this is electrical and should as a minimum be done by someone with that expertise.

*** UPDATED 7/12/18 *** - Seller has addressed the earlier safety concern. The original version of this product used a quick connector that was dangerous (see below). The seller of the product took my review seriously and reached out to me the same day. They understood the concern and let me know they were going to change to a different quick connector. The seller shipped me a replacement at no cost and for my evaluation and feedback. The new lever quick connector is a significant improvement. The new connector ensures that a bare wire is no longer exposed. Additionally the new connector also firmly holds the wire. I gave the wires a good tug once it was locked in and didnt see any movement. The new lever connector makes it very simple to connect your wiring. Simply strip the wire the the recommended length. Note that if you look at the bottom of the quick connector there is a reference that shows how much wire should be stripped. Do not exceed that length to ensure the wire is fully shielded inside the connector. The quick connector works with both solid and stranded wire. The functionality of the unit is great. Its easy to install the app and connect devices to the app. Instructions are clear and straight forward. It was also very easy to add to Alexa app for voice control through the Echo devices. Even if you dont have an Alexa product the app is easy to use as well and also includes an option to schedule on/off times. The only negative about the app is it doesnt offer widgets (I use the Android version) which would allow a widget button to be put on the screen of your phone. You can then turn the EMylo device on and off without having to launch the app. All other apps for similar products that Ive used offer this, so hopefully this will be added in a future version. _____ORIGINAL REVIEW_____ WARNING - This product can be very dangerous due to design flaw Please note - I attempted to write a review for the single unit however for some reason Amazon would not permit me to do so. However I am a VERIFIED purchaser of this unit. Based on what I found, I wanted to get my review posted before someone gets injured. The biggest factor that eMylo uses to differentiate itself is the quick connector. Well, its also its biggest reason for only 1 star. Ive used the competitions model, and I did find that a bit clunky to get wired. So when I saw this with the easy connector I was quickly sold. However, in reality this connector is not secure and Id also say its not safe. Let me explain. There is a short wire that is connected inside the unit (basically the same as competitors product) and then connected to the quick connector. This is very visible in the pictures in the listing. When I received the unit I gave it a look over, and a slight tug on the connector caused the wire to slide out of the connector, exposing a bare wire. So imagine if you had this connected in your home and the wire slid out of the connector, exposing a bare live wire that your child, spouse or pet could get zapped. The quick connector SHOULD NOT BE USED, IT CAN BE VERY DANGEROUS. Fortunately, you can disconnect the quick connector wires and then connect wires inside the unit, same as the competition, but then theres no difference between this and other products that are on the market. I did test the unit, discarding the quick connector and attached wires directly inside the unit, I found that the unit worked well. However, this then pointed out that there is another design flaw. That same connector could also slip off wires that youve connected to it. Imagine that you have one end connected to your outlet and those wires slip out of the quick connector. You now have exposed wires as well. I tested connections into the quick connector and found that wires can slide out with only a modest tug. At this point, with the danger of live wires being exposed by accidentally slipping off the quick connector Amazon should immediately stop selling this product before someone gets injured, or worse.

Cutting wire to install this device was weird. Wanted to use it on wall mounted switch but did not work. Trying to repurpose the devices.

I love this switch! I bought a second unit because the first one worked great and allowed me to control devices in another room. I have one connected to an exhaust fan and the other to a dehumidifier. I can now control each from my Android phone. With the addition of a camera, I can easily see and control the conditions without having to run into the room. Correct placement of the switch and I can bypass automatic temperature and humidity controls in an emergency. The clips for the wires were a little confusing and i didnt use them on the first switch. I thought they were garbage because they didnt hold the wire tight. When the second switch arrived, my nephew showed me that I was not opening the clips all the way. From that point it took us under a minute to strip wires and connect to my phone. That simple. Setting up schedules are a little grueling and the app definitely could be better. But it works and with time and creativity you can accomplish most anything. (48 entries for an action every half hour).

Very easy to install, compatible with my room!

as described, would buy again

Great easy to install product

The code to get to the correct software did not work and the item is too big for a single gang electrical box

I used this to replace an old mechanical wheel style timer switch for my outside lights. I was able to pull the mechanical guts out of the box, and replace with this device. hooking up was easy, and setting up the connectivity was also very easy with the app. I was able to program it to turn on my lights in the morning, and turn them off at sunrise, and turn them on again at sunset and off at a set time. No more adjusting the timer as sunrise and sunset changes. The entire project including wiring, starting an account and programming the events took less than an hour.

Very easy to use and good WiFi range. Used to control pool cover pump
