Description
The SM309 Zigbee dimmer switch is an innovative AC phase-cut trailing edge Zigbee dimmer providing smoother dimming control. The SM309 dimmer is designed for 100-240VAC input and output, 1 channel and maximum 400W output. The innovative minimum brightness setting enables users to set a minimum allowed brightness and smoothly increase the brightness to 100%. The SM309 dimmer is compatible with Amazon Echo Plus/Echo Show 2nd Gen/Echo Studio, Philips Hue and Tuya-compatible ZigBee 3.0 gateways, and can be controlled by a ZigBee gateway interface, physical light switches or remote controllers that can be added to the Zigbee network and binded with the SM309 dimmer.
The SM309 dimmer switch can be linked to and controlled by max. 30 zigbee remotes that support zigbee light link through the touchlink. Also supports the new zigbee green power feature, and can binded with and controlled by up to 20 Zigbee green power remotes directly without zigbee hub or a gateway.
We strongly recommend that you engage a qualified electrician to perform any electrical works.
INSTALLATION:
1. Wire up the switch as per the enclosed diagram and place the device as close as possible to your Zigbee hub during the initial setup
2. Press the reset button 5 times to reset the switch and initiate the Touchlink connection. If you do not intend to reset the switch, press the button 4 times to initiate the Touchlink connection only.
3. Amazon Echo Plus/Echo Show 2nd Gen – Ask Alexa to discover new devices. Philips Hue – Add a new light through the Settings->Light Setup
4. Any other compatible Zigbee hub – follow your own hub’s instructions for adding new devices
When the dimmer is failing to connect to your compatible Zigbee hub. Ensure the dimmer has not been previously added to Zigbee Hub/Alexa/Hue app before repeating the initial procedure again. If the dimmer is already present in the devices list, please remove first.

I love these little guys. Rock solid, easy to wire and they do everything. I just keep buying more!

A bit fiddly to fit in the wall box, but once I cut the wires (fitted by the original wiring) it all went in very neatly.

They do the job I need them for, but are very expensive for what they are. ZigBee bulbs, even the pricey Hue ones are significantly cheaper.. If these were closer to the price of the bulbs, I would buy them instead if the bulbs.
My only technical gripe is that the external switch contact is not volt-free, it needs 8-220 volts to operate which is awkward. I would much rather they were dry contacts.

Great pieces of kit. So far all stable.

easy to connect to my existing Philips hue setup.

This works amazing with my kitchen LED’s and Philips hue – no flickering at all. It’s far smaller than you think so easy to fit in standard ceiling recess.

Very clear instructions make it easy to install. The size of the dimmer is good for fitting into a 35mm deep back box. Works really well with Philips Hue bridge allowing a good range of dimming.

I am actually pretty impressed with this and will almost certainly be buying more, very easy to set up through the hue app as a hue light . works well , has a minimum dim setting which will stop flashing lamps and the bit i liked the most which they didnt explain in the listing is that if you use a momentary switch ( push type) you are able nopt only to turn off and on at the switch but also dim/raise brightness by holding it down

Slightly fiddly to pair with Hue, but stay calm, keep trying and it will eventually happen. Once it does, you’re good there on. It dims well and controls a loop of GU10s nicely. I’ve tried lots of Zigbee dimmers and this wins on Price/Function. I know it’s not cheap, but it works well, and you’ll still be pressed to find something cheaper that works. The best thing though is the small form. It is also silent. A few others I’ve tried do let out a quiet but present buzz, while this one doesn’t. Recommend this highly.

Easy to install, setup, and reliable (unlike other designs with push connectors). 5* for that alone. Ability to set minimum dimming is a nice feature. Only downside so far is I noticed more flicker at low light than my other unit if this type. I’m going to experiment with different bulbs. Also seems to have a narrow band of dimming – is it goes from no light to full brightness between nominally 20% to 50% (according to Hue) — where I see flickering at less than 30%. Don’t know if that is some configuration I’ve missed. But another unit I have ranges from 13% lowest to about 90% highest.

Performs exactly as needed and easy to set up

Used this with some GU10 dimmable COB LED’s in the kitchen and I have to say I’m impressed, works very well, dims right down to off without any flicker!.In the UK your going to need something like a WAGO box lighting junction box, and 3 x WAGO 221-413 3 way connectors. (These fit the box perfectly and can handle up to 32A, more than enough for some lights.)In one side using 1mm 2 core and earth cable (6242Y) you will have your incoming lighting circuit, your cable to the switch and your cable to your light.In the junction box you will connect your neutral from your lighting circuit, your light and a neutral wire going to the Samotech module. Your live connections will be from your lighting circuit, to your switch and a live wire going to your Samotech module. You should have 3 earth wires which all link together in the third wire connector.You will need to fit a wire from the other N connection on the module to the -A2 connection, the switch return to +A1 and your lamp live to the OUT connection on the module. This can all be fitted out of the way through a standard spotlight hole above the ceiling.The module when connected to smartthings or hubitat allows you to set the ramp speed for on and off and is very smooth without any staircasing of the output, the local control from your existing switch is best if the switch is replaced with a momentary switch but will work with an existing switch, but will require switching on off, on off to turn once on then off, dimming is on off then on and hold whilst the lamp increases or decreases in brightness.The module also acts as a zigbee repeater.It is possible to set a minimum dim by dimming to off using the switch, then increase until the light just comes on and let go of the button (Or switch off is using conventional switch), then press the button on the back of the module.Holding the local switch / button to dim will only then dim down to this level.Note: remote control will still allow a dimming level of 0 which in effect turns the light off.Internally the unit look very well made and appears to use good quality components.

It worked for the purpose it was purchased for (Alexa / Hue Remote control)Installation was simple, I did a test-bed build first to get it set up, but it wasn’t necessary as it connected straight away and slotted into the ceiling cavity without issue.

Bit expensive but works well. In this case converting a ceiling lamp with 3 x G9’s in it to be dimmable by alexa (and Hue app).

I bought this to convert some existing wall lights to work with Hue that use the very small halogen bulbs for which there is no smart option. Installation was pretty simple but as a previous reviewer had said, pairing was anything but. There are no hue specific instructions so it’s a bit of trial and error. Pair it before you install it in its final location as being close to the hub is the key. I found I had to press the reset button 5 times to initiate the correct mode. Once the hue app discovers it it’s plain sailing. It appears as a dimmable switch and works right down to a very low level of brightness. Does exactly what it was meant to do. Very happy.

Work very nice!

Just installed. Works like a charm with hue and has allowed me to include my under cupboard lights in the app very easily. Will get more to try on my ceiling spots.

after delivery i found that the philips hue bridge and homekit only supports genuine hue products, obviously one would want as much integration in one app/ecosystem as possible.i have a spare raspberry pi 3 lying around so i installed homebridge on it then installed the hue homebridge plugin, few configurations anf scan of the QR code it not integrates in the home app on iOS and OSX software.

Works well with SmartThings hub using generic device handler (ZigBee Dimmer). Works well with Ikea dimmable LEDs (various). Very low minimum light level may be achieved. No blinking of LEDs at all. 6 of them fitted in all my house ceiling lights behind momentary switches on the walls, but had to replace shallow boxes for deep 47mm Dry Lining Boxes to accommodate all extra wires and Wago connectors. Automation works well with Xiaomi-Aqara motion sensors. Product I was looking for, for almost a year, but price could be smaller. Recommended!

I bought this as I wanted to retrofit an existing ‘dumb’ chandelier to connect it to my Hue smart lighting setup.This little dimmer is perfect for the job. It is small enough to fit into the base of the light I wanted to convert and was very easy to connect.I followed the included instructions to connect it in my Hue app via the Hue bridge which worked first time without a hitch.Voila – the chandelier now behaves exactly as if it was made to be a dimmable smart light in my Hue setup.

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.
