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)

The media could not be loaded. 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!

Works perfectly. Easy to fit. The original settings were right for me so not had to change. This is mounted at the end of the corridor that runs through my flat and activates when coming into it from any room.

works as expected, it is not easy to press the small button, tried to change the light sensitivity but didn't make a difference, I want it to avoid turning the light on when the daylight is in the corridor but didn't make difference

Quality is well worth paying for.I bought because of the ability to make adjustments but the default settings are pretty dam perfect.From build quality to performance, BRILLIANT.10/10👌

The media could not be loaded. Absolutely amazing and very easy to install NO NEUTRAL NEEDED.

Great bit of kit. Does exactly what it says.

The sensor stopped working after a few weeks!

The installation instructions that come with this Sensky 3 in 1 PIR Motion Sensor Light Switch can only be described as basic at best. To install the switch, you firstly have to take the front cover off to get access to the two wall mounting holes, which, in my opinion, is quite a tricky job in itself. You then have to remove the PIR sensor and operation switch covers to gain access to the two, wire securing screws. You'll have to work all this out for yourself, because none of this is mentioned anywhere in the instruction leaflet.So if you are a DIY electrician, or have not had any kind of experience fitting this type of sensor before, this may not be the best switch for you.In fairness, I does work quite well once it's installed, however, I would strongly recommend hanging on to the operation leaflet, as it is a very complicated, button pressing and holding procedure to switch between the three different modes, which in my opinion, would be almost impossible to do by trial and error.
