    I was looking for a product to put inline between the light switch and a string of lights 6 dimmable Luceco LED downlights and then connect to a Zigbee smart hub (Osram Lightify) and this device has done the job perfectly.
    Firstly, whilst researching what type of dimmer to buy I found that I needed a trailing edge dimmer and the supplier of this product got back to me really quick with an answer to my query about this product. After ordering, delivery was 2 days ahead of schedule through the royal mail.
    I identified which was the first light in the chain and then pulled the light out of the ceiling and then to start the wiring, I identified which was the wire from the switch going into the first LED downlight in the chain and then (after turning off the power, and checking the power was off) chopped the cable. The Line and Neutral from the switch were connected to L and N on the device respectively and the earth was sleeved and taken to a single choc connector. The screw terminals in the device seem to be very secure. The Line (Live) for the first downlight was connected to the terminal marked as a lamp symbol (circle with cross in it) and the Neutral to the N, the earth was then sleeved and joined to the other earth in the choc connector.
    The device is small so pushing it back up through the downlight hole in the ceiling was easy and once the electric was turned back on it was quickly paired with my Osram Lightify hub.
    Alexa found the device immediately after a device rescan and I am now able to dim my kitchen downlights and turn on/off by voice command or by the app.
    One bonus which I wasn’t expecting is that you can also preset the dimming percent with the Lightify app which normally only works for me with Osram bulbs. When this is done, if the lights are turned on/off with the light switch then they will come on at the preset percentage and not on full like some others.
