BroadLink Smart Wall Light Switch, 1-Gang Single Live Wire Switch, No Neutral or Capacitor Required, Push Button, White,Compatible with Alexa, Google Home and IFTTT, S3 Hub Required (With Hub)

Managed to install one of these myself. Two gangs for two main lights (used capacitor in ceiling rose for each) and a third to trigger three Wemo switches, connected to comfort lights. I was using IFTTT for about a year before IFTTT service started to become extremely unreliable. Even paying for Pro didn’t change it. You would switch the third switch on and wait up to 5 minutes for the lights to actually come on.Eventually I’ve found a more reliable solution. Home Assistant on a Raspberry Pi 3. It’s pretty fiddly to find integration.You will need to read the entire thread on the Home Assistant community page titled “Broadlink S3 hub support”. You will then need to follow mnayef95’s readme from his Github page: Support Broadlink s3 hub in AppDaemon.Now my switches work perfectly and instantly, without relying on a cloud provider.WARNING: both setting up the main lights with the capacitor and setting up the Home Assistant with a Raspberry Pi and then installing HACS etc. is not for the faint hearted. I would say you definitely need electrical and IT experience to set these up.

I do like this product, but installation took longer than I expected, essentially because of missing/unclear info. Which I will try to supply here.1. You need to prise off the front of the switch - the bit that moves - to access the screws that attach it to the wall. This requires a large amount of strain put on the top left hand corner, so that one becomes confident that the whole thing is about to explode in a shower of plastic fragments. Courage, dear heart.2. Because of issue 1, above, when I initially wired up the switch, I didn't replace the cover when testing it. As DPM notes in his review (which I only noticed afterwards), this is a sad error. Like him, I convinced myself I had a faulty unit. The cover MUST be in place for the switch to work.3. The Bluetooth pairing was a bit problematic. I had several goes, moving the hub further away, before it mated.4. As others have noted: you do need an S3 hub. If you ordered a version of this without a hub, you are out of luck. Also, if you do get a hub, know that it needs a USB power supply, which is not included.The instructions are printed in a font size teeny--, in a light grey ink, and are less fulsome than one might wish. They are instructions for somebody who has done it before.Despite all the above, I am very pleased with it. But I am new to this voice control lark, so perhaps naïve.

Replacing a standard light switch, this will not cover over the paint marks if you painted around your existing switch. And you’ll need to make the fitting much deeperBut if you’re not too fussed with those things, it works a charmAnnoying it doesn’t have home-assistant integration tho!

Quite happy with it so far. Fairly easy installation, pairs fine with the app and I've managed to integrate it with HomeKit via homebridge. Will definitely need some spacers like other suggested.

Got super excited when first bought a bunch of these to replace dumb switches around the house. The problems started immediately - devices won’t go into pairing mode no matter what. After god knows how many attempts I was able to get 75% of the connected to those S3 hubs (which make a terrible humming noise btw). Now a few months later I’ve decided to switch to a new Wi-Fi equipment - so had to reconnect the S3 hub. Well, now not a single of 5 remaining switches connect so I have a bunch of decent looking dumb switches… the only reason it’s not 1 star is that they look better than an average UK switch. But an absolute fail of a smart switch.

UPDATE: WARNING one hub will only control 8 devices! I now have 9 of these switches and 2 hubs. A bit of a hiatus whilst I found out the essential knowledge about 1 hub = 8 devices MAX. I now have used all 3 types (1/2/3 gang) and all have worked flawlessly and continue to do so. Adding devices to hubs is easy. The integration with Alexa works well.I now have 4 of these switches - 3 single gang and one two gang and a tiny BroadLink hub. Main control is by Alexa which uses the BroadLink skill to communicate with the hub. The switches are good quality and safely sealed. The instructions are OK but printed in grey 6 point type - not easy to read! They fit a UK wall box BUT only if you have an extender - £2 from another supplier and delivered together. Wiring was straightforward EXCEPT when replacing a 2-way set up which required some careful reading of a web page and some wire labelling before I took it to pieces. Putting the wall screws back in is fun with an extender otherwise installation was easy. The BroadLink app and hub worked well after the first time - it takes a while to get through the setup at first. The last one took 3 minutes all down to experience. I have replaced a 2-way circuit in my kitchen (two switches one light). This means ONE powered switch controlling the light and one unconnected one. You cannot have an unpowered switch so I used a 2 gang switch one wired to my garage lights and the second switch unconnected as the second of the 2way. Setting up the automation in the app was simple - you need 4 routines if one is put on switch the other on, another for off and two more for the other switch. Simples.
