## Questions & Answers

**Q: Is this suitable to use with a granny cable 10 amp to charge my electric car?**
A: These are rated to 13A, however please check with a qualified electrician around the requirements for electric vehicle charging. The issues arise from poor installation and underrated cables which can lead to over heating and ultimately damage to your installation and car.

**Q: Can I use the smart socket together with the app to dim a dimmable outdoor light?  Or does the app only allow sockets to be on or off?**
A: The app only allows switching on and off. We do have smart lamps which can be dimmed and in many cases colour changing too. Please visit the Knightsbridge store and look at our smart product range

**Q: How do I get this into pairing mode?**
A: Don't even bother. Send it back for a refund before the initial 30 day Amazon warranty is up. If you have to deal with Knightsbridge for a warranty claim, you may as well throw it in the bin and write off what you paid for it. These are absolutely useless. They work for between 6 and 12cmonths, then disconnect from wifi permanently.

**Q: can the mains cable enter the enclosure at the bottom? ie are there knockouts on the bottom of the enclosure to fit the cable glands?**
A: Yes there are 3 knockouts on the bottom for cable glands, as well as 3 on the top and one on either side.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Lovely piece of kit
*by R***S on 14 September 2025*

Does the job great, and looks lovely.

### ⭐⭐⭐⭐⭐ Excellent device - Really easy install and set up - Fix and forget
*by R***. on 25 November 2022*

I replaced a single outdoor socket with this device on my patio. Almost a straight swap over as looks the same manufacture. Just had to be careful to make sure the mounting holes lined up. I did test it first to see how easy the set was. I use the smart life app and it was very easy and simple to set up. You can set timers individually for each socket - monitor the power usage - and have a common on off. You can also just switch them on from the switch if you havent got your phone. The switch is a pulser like a doorbell so feels a bit strange to use but operation is tactile and device generally feels good quality and waterproof. Fun to play with and show off - Now the novelty worn off just works and the lights and water pump just do there thing and all is good

### ⭐⭐⭐⭐ Works fine but needed a WiFi extender
*by A***R on 13 September 2021*

I purchased this plug to remotely control garden lights. It was installed by an electrician and appears to be waterproof. Pairing was another matter I have tried for 6 days to pair this to my WiFi but it would not pick up the signal the socket fitted at the back of a 4 bed house the router in the hall in the centre. I have had to buy a WiFi extender to enable the socket to pick up my wife. Moving the router nearer the socket worked however this compromised the wifi signal to my office at the front of the house. All in all it now works well not I've paid an additional £60 for a WiFi extender. Having also paid am electrician to fit thus socket and the purchase of the wifi extender it has worked out to be a very expensive outdoor socket. Had i known I needed a WiFi extender I would have just purchased a normal outdoor socket with a manual timer which would have been cheaper.
