KnightsbridgeSN9KW Smart 2G Socket, White, 8.0 mm*86.0 mm*146.0 mm

Used to remotely switch on 2 remote lighting sockets, total draw approx. 1,125 w (5 amp). Well within specs.On reboot works, then shortly after fails turns off and will not reconnect - re boot and will then reconnect for a short time again. Each instance time period for failure reduces. Having said which other 10 or so units all working ok and happy with these. Defective item replace from spare I had is stock and presently fine. A bit frustrated with amazon service as 2 attempts to get call back failed and just kept saying call failed try again but did manage to resolve refund through chat.

Originally bought for the decking lights in the garden.Setup is easy and straight forward.The app is really good and also tells you energy consumption for each socket.Bought a second and used it as an extension lead so I could check how much energy certain appliances were using after the hike in energy prices.If they had USB sockets I would seriously think about changing the sockets in the house.

AVOID these RUBBISH SOCKETSQuality control is non existent.Waste of moneyWarranty does not include electrician costs to replace faulty socketsI bought 6 of these sockets hoping to monitoring energy usage in each room. All of them stop working one by one. Some disconnected from network and completely dead, some stops responding to switch and no way to power off the socket.Warranty from Amazon only allows you to return the item for replacement and no repair can be done. I have to make new purchase so electrician can takeout the faulty ones and let me ship back the faulty ones for refund. Also note several faceplate have cracks on them after several months of normal usage.Initially Amazon staff sayid they can pay for electrician cost for replacing the socket, then refused to reimburse when I submitted electrician invoices to them. They waste my time and make me out of pocket for their defective products.The 6 replacement sockets once again not functioning properly. Only one still works properly and 5 are either dead or only has one switch get power and can’t be turned off. I will have to pay electrician to change to other sockets again. This product simply waste my money 2 times.Knightsbridge needs to find out why their product has a 100% failing rate within less than one year.

I have about 4 of these installed at the moment and have them hooked up to home assistant.Working great, connects to app easy enough and hooks into HA directly without and issues, with automation to kill sockets with low watts usage and to turn on with other checks.Did have it hooked up to Google Home, quickly removed after a dayMore of a google issue - there is no option to exclude the sockets from voice assistant, so if Google mishears you, you end up turning off all the sockets, killing say wifi/router and all the stuff that makes it work lol.Of the 4, 1 decided to start acting up within 2 weeks of install and did the following.- Drop off the wifi- Randomly trip both sockets- Switches would stop responding meaning that the mains breaker needed flipping (this would resolve it)- The above would increase in frequency as time when on until I replaced with a new one and returned the clearly faulty device.- I had HA turn the socket back on as soon as it came back online and found it to be off.Strangely I contacted Knightsbridge directly and explained the problem and with a little bit of back and forth (weak wifi explanations, yeah like its mean to drop and kill the socket if it has weak wifi? sounds like a design flaw if that is the case... tbh I think the support person didn't understand the problem)Anyway, they said I should contact Amazon directly for a replacement which I did but a few days later received a replacement from them directly which wasn't communicated/not complaining just Stange to say go do this but do something else.For the most part they do what you expect them to do, just don't connect them to anything that is critical for use, unless you have a UPS in place to protect from the power outage.Pros- Works with HA- Get stats for voltage/amps and watts- Control switches remotely- Easy to fit / does require you to kill the power to the socketsCons- Quality control? might be unlucky with just the one- Support could work on communication, only one interaction so hard to say if this is an actual problem.- No way to reset if you do have a problem and the switches stop responding- Would be nice to control the brightness of the lights on the switches.Update 02/07/2023Pointless, they will die after a period of time and because of how they die they cause interference that breaks wifi in the vicinity.All of the ones I've had have died now, not worth contacting knightsbridge, support is massively lacking last time i used it.

Potentially useful to turn boiling water heater off overnight. However it had to share with a dishwasher and kept tripping when the 13A limit was exceeded. I know I should have read the spec in more detail but it is easy to assuming that 2 13A sockets will both provide full power.The App was fairly awkward to set up.

So it is really easy to install into the socket no difference to replacing a standard socket.My only complaint was there no mention of pressing the WPS button on the modem.Downloaded the smartknight appRegister it.Then I got access to my modem switch of the 5g functionThen got the socket in pairing modeEntered the wifi password int the appPress the WPS buttonThen on the app press add device hit the socket iconWait success.Then back to your modem and turn on 5gAgain.

This socket hasn't missed a beat since I got it a few months ago.Until now.It drops off all networks. Dies over night. Needs power reset.Has become a total pain.Can I return it? Who knows.UPDATE: amazon offered refund on return 👍

Works Great but unfortunately let down by killing of Internet speed when using power line adapters. There is always drop off using such devices but after comparing the new speed to the speeds I used to get, it's seen a drop of around 25Mbps compared to my old (non smart) socket.
