Sensky 3 in 1 PIR Motion Sensor Light Switch with Occupancy Sensor/Vacancy Sensor/On-Off,2-Wire Technology, 5A, AC110~265V,PC Fireproof(No Neutral Wire Required)

Bought this for our bathroom so the kids don't have to worry about reaching the light switch, and it's been a great little upgrade so far. Installation was straightforward and the sensor picks up movement reliably when entering the room. I like that it gives you different operating modes, so you can set it up to suit your needs rather than having the light on all the time. It's made life a bit easier for the children and saves the usual reminders about turning lights off. Only had it installed for a short time, but so far it's working exactly as expected and I'm very happy with the purchase.

Early days but so far so good. I have a small closet toilet without natural ventilation, and rely on an extractor to shift air. The Xpelair fan I have goes through capacitors more than I would like, and as a result the extractor goes off with the light, instead of with the timer delay. I can’t be bothered replacing the fan PCB yet again, so have gotten this to effectively do the same job, and keep the fan on for 3 minutes with the lights. Additionally, it removes the need for anyone with possibly damp hands after washing their hands, to touch the switch. It was quite easy to fit, but do read the instructions. It’s pretty easy to configure it afterwards. I don’t like how the metal plate isn’t grounded when used with a plastic backbox, so I may look at that in the near future. I only had a L and N wire and this switch works as expected. Like most PIR sensors, they are not great on the vertical plain, so my youngest will have to wave his arm upon entering the toilet. No doubt visitors will be pressing the buttons too, so it is nice to test that it still defaults to going off on the timer even after the button is used to turn it on.

Great switch as switches go!!

Well made but a little confusing. These are well made items and easy to fit. However operation is a little counter intuitive. To turn the lights off you have to press a tiny button that doesn’t look like a button, pressing the main button just turns the lights off for a few seconds until the motion sensor detects something. I have these in a guest house and guests try everything including holding down the main button which then changes the settings and makes things worse. Not one person has figured out how to turn them off without instructions!

Exactly what I was looking for and works a treat. It just needs two wires, (not three, and not four, unlike the first two I purchased from Screwfix and Toolstation) which is all I had sticking out of the ceiling from the old pull cord. The installation is a bit fiddly, as I originally struggled to workout how to remove the sensor to get at the wiring screws, but some kind soul on here had posted a video.

Great switch. Works perfectly

Good but no time adjustment

This is a two wire sensor and will replace any single light switch. It is quite deep, at around 30mm so be sure to have enough room to install it behind your existing face plate. It fitted the existing switch mounting box in our walk-in wardrobe perfectly (Installed in a wooden fascia, not a plastered wall). Worked straight away after powering the lighting circuit back up and I find the default sensor settings to be perfect for our needs. I like the fact that all the settings can be changed from the two buttons on the front if required. (Some units need to be dismantled to adjust them). Works well with our LED light strip and LED ceiling lights combination. This is well built, easy to install and seems good value for money. Looks good too!
