Bkiyougo WiFi Smart Switch Light Switch, Works with Amazon Alexa/Google Home,...

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.

Great value, appear to be well made and decent quality, easy to configure, work immediately with Alexa, respond rapidly to Alexa commands. Pleasantly surprised by these little doohickeys. You need a neutral wire so these are no good to replace most light switches because they are usually a single switched live wire and the neutral will only be available at the light socket, but not the switch panel. You can therefore install this at the light socket of course but that is likely to be less straightforward. -- I post honest reviews, only of products I've bought, or have experience of, and only to help other buyers. If I have had a problem I'll explain what was done to address it. I don't receive any kind of reward for any of my reviews.

These are great for smart enabling your lighting around your house - but only if you're competent at electrical wiring. Its suggested that you could fit them in behind light switches but they're 2cm deep so there's no way they'll fit into an existing wall box in a solid wall... However if you've anything you want to smart enable where you have a Live and Neutral input and require a Switched Live output, then these will do the job great - and if you can get to the wiring junction boxes of your house lighting in the ceiling or loft, then maybe these are useful in that situation. I've fitted them in my outside lights (or alongside in a weatherproof box) connecting the switched live to the swithched-output of the PIR and now I can turn all my outside lights on via alexa. Its great for driving home at night and even before I get anywhere near the house, I can use my phone and tell Alexa to turn on the driveway lights so that I can see when I'm trying to park... I've also used one to Alexa-enable my garage door opener. You can buy proper smart garage door openers, but I just used one of these to then trigger a separate 240v relay which then triggered the door opening contacts on my door motor. If you're a competent electrician then these are a great way of smart enabling things around your house but they';re not plug-and-play so if you're not competent electrically, seek out something else...

Handy for remote control of appliances and lights.

These are amazing little wifi switch I use them to put garden lights on at sunset eassy to connect to wifi and couldn't be simpler to wire these unit

Turning out to be a waste of money. Glad it was only cheap. Easy to connect into external light junction box as I am electrically competent. This WILL NOT fit in a standard UK light switch back box despite its small dimensions. Easy to connect to App and Alexa. It stays on line for a few hours before going off line. Doesn't come back on by itself, I have to flick the breaker off and back on. After a few hours its off line again. Was £15 for a twin pack but would still be a waste of money if it was a penny. Replaced this unit with a SONOFF MiniR4. Smaller item, just as easy to connect and use. Has remained stable so far.

Lovely product for adding wifi capability to anything. Small enough to be house in a light fitting. And what you probbably didnt know, is that they can be used on DC wiring as well, so if you already have some low voltage lighting strips and you dont want to replace them, you can simply wire them into the DC side. Mine are working perfectly at 12V. Make sure you follow the diagram. And best of all, they dont need a dodgy app to control them, easily plugs into smart life

Exelentes muy prácticos y faciles de instalar

Excellents

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.
