WiFi Smart Switch Light Switch, Compatible with Alexa/Google Home, APP Remote Control, Voice Control, DIY Mode, Timer Function, LAN Control, No Hub Required, 2 Way 16A(4 Pack)

I use a lot of electronic modules but these are "crazy" good. They work, have excellent range, smaller than you might think from the pictures (small enough to fit into an existing electric box {depending on what else is in there] to automate an existing light switch}), and an unbelievable value. However, as usual for Chinese electronic products, the engineering is excellent as is the construction quality, but the documentation is the weak spot. In particular, there is one misleading wiring aspect. The unit has a neutral line (white) for the line voltage in and a second neutral line connection for the output. Usually, if controlling a light or other line operated device, there is only on neutral wire. What they don't say is that you don't have to use the output neutral connection. You just need three wire connections: hot (black) in, hot (black) out and the line neutral (white) in. The two neutral connections (in and out) are likely just connected together inside. They also show a connection for a switch, which is good, but they don't mention that a switch is not required since there is a built-in switch on the body of the device (used for pairing as well as on/off). Of course, you will likely use the "Smart Life" app for control and/or Alexa or Google. I will also say that this device paired very quickly, faster than others (hold down the button of the device until the blue light blinks putting it into pairing mode.) It is also a real switch (likely a relay so no dimming) and I am using it to turn on/off a couple of 1000 watt motors.

Inexpensive. I bought 10 of these after I figured out they can be flashed for local use without having to go through the cloud. MQTT works well after flashing. Flashable with OpenBeken - see my post on details, teardown, and settings if you want to do that. It is on elektroda.com with title :Tuya DIY Smart Switch T1-CHL AU5101XA Flashing Issues with OpenBK7238_QIO_1.18.247 Firmwareas . I also published an OpenBeken node for IBM's node-red home automation system which I uploaded to npm and the node-red Library. Inside, it has a BK7238 (T1) chip and 2M of flash memory. The same outside case is used by a lot of vendors but what's inside is often quite different vendor to vendor - with no version numbers or markings on the circuit boards. This particular circuit appears well made with decent components. Wiring is totally unlike wiring other popular home automation brand switches like ShellyR1, Shelly mini, SonoffminiR4, etc. In that the switch teriminals CANNOT be wired to either Neutral or Live wires without a loud noise and magic smoke coming out of the device. The two switch contacts S1 and S2 are "dry" and tolerate 3.3V logic level detection circuitry only. So far I have 16 of these running fine on OpenBeken and interacting with node-red home automation system.

Work excellently, very easy to connect to the internet works with my Alexa. very happy with them

I have a water pump in a remote location and wanted to be able to turn it on or off using the app. The first couple of weeks it worked great. Then out of the blue I needed to reset it. Ok, no big deal. Then it was several times a day. Now it only works via Bluetooth connections. I contacted the seller and after a couple of weeks I have not gotten any reply from them. Terrible product, even worse support.

So far, I've only installed one for a floodlight. Nice and bright. Had no trouble. Connecting to the app(SmartLife) or my phone, put it on a schedule and it works pretty good. I do have one complaint, when I'm home on the same Wi-Fi, I can manually turn off and on. But when i'm away from home on a different Wi-Fi, I CANNOT turn it off or on Unlike other brands that I've bought before that I can control Away from home..... Even though they are not as bulky as other brands, They weren't as small as I thought They were gonna be... still much easier to work with...

Works perfectly! Very small so it fit nicely in the ceiling. Easily connected to our Google Home.

I bought a package of two switches because it had the best price for a Wi-Fi switch I could find on Amazon at that time. I found they work fine over Bluetooth but lose Wi-Fi connection after about a day, making it unusable unless you are near the switch. I contacted the seller (Smarthome_ Direct) and they were responsive. After some trouble shooting attempts, the seller sent me replacement switches. The replacement switches had the same issue. Either I was unlucky enough to get batches of bad switches twice, or it appears the switches are designed to fail to stay connected over 2.4GHz Wi-Fi router. I’m still giving 3 stars for the seller’s great after sales service attempts. If you needed Bluetooth only switches, it might work out for you.

Fairly easy to set up. You do have to be mindful of how much wire are you leave exposed because there isn't much room for them to insert. Overall I have been happy with them so far and have made another order.

Exelentes muy prácticos y faciles de instalar

Excellents

I have to preface this review by saying that I have a background in electrical/electronic engineering, so I am not your typical DIYer; however, with a bit of Internet searching for videos, practically anyone can use these. Firstly, why did I buy these and not a smart bulb? Two reasons: (1) I did not want to spend a lot of money on a smart LED bulb only to throw it away in a few years when it fails, plus I have some really cheap LED bulbs fitted that work just fine; and (2) I wanted something that just worked with my router and did not need a hub. Second, why these in particular? Because they are really cheap, small enough to hide away in a light fitting and work really reliably. These need both live and neutral feeds, so require fitting at the ceiling rose; you can buy ones that just need live and 'steal' a neutral feed through the bulb that can be fitted at the switch, but they are more expensive and there is no room to conceal them behind a UK light switch. I have attached three photos to show you how I have concealed mine: (1) I bought some large rose covers to hide the switch for standard light fittings; (2) I hid the switch in the little junction box for my LED floodlights; and (3) for my new, low-profile LED kitchen strip light that fits flush to the ceiling, I just cut a recess into the ceiling to tuck the switch into which is then concealed when the strip light is fitted. The live and switched-live feed to your wall switch connect to the two switch terminals on this WiFi switch; that means you have a no/low voltage switch circuit. Using the app, you can programme the wall switch to either toggle the light on and off regardless of which position the switch is in, or sync it so that the light obeys the normal 'up is off' 'down is on'. Whichever way you programme it, your digital assistant of choice can always override it when you give voice commands to switch on or off. I use Alexa for everything, and I have a routine to turn my landing light on at dusk and off at dawn for security when I am away. Finally, these work very reliably [so far] and do not need a very strong WiFi connection to do so. I am a very happy customer.
