The device is small enough to fit in the base and provides good value for money, though some find it a bit expensive. They like its appearance, with one customer noting it adds ambience, and another mentioning it works perfectly with dimmable LED downlights.

Just Tested the SM309 Dimmer Prior to Install – First Impression – FANTASTIC!
I bought this to control some LED lights where I cannot fit Hue lights. Haven’t installed properly yet, I just did a test and rigged a 4-way GU10 spotlight fitting to it, with 4 good quality Megaman 6W LED bulbs. I have had loads of issues dimming normal LEDS, as some dimmers can’t handle very low loads – even spent a fortune trying different LED bulbs. With my LightwaveRF dimmers, I can’t have any of my LED bulbs they control dimmed to a very low level, probably 50% at best.I had low expectations from previous experience of LED dimming. But wow – my preconceptions were thoroughly smashed.Firstly, it was a doddle to pair, the Hue bridge saw it instantly. Others have said there can be issues – apparently it has to be quite close to the Hue Bridge (mine was within 2m of it). Shows in the app as a Hue white light bulb.Secondly the dimming range was fantastic! From 1 to 100%, no problems, no flickering. Had issues before (especially with my LightwaveRF kit) where a dimmer can handle, say 4 bulbs worth of load, but if one goes, then the lower total wattage starts to cause issues with flickering etc., when dimmed. Not with this, pulled 3 bulbs and the single 6W bulb worked perfectly, no degradation in dimming performance at all.Thirdly – and this was a surprise – it supports Hue power-on behaviour. Very unexpected and cool. I have read in a few places it supports OTA updates when used with Hue, will have to wait and see for that one!Really pleasantly surprised by this unit, will be fitting this soon, and getting a few more – and the switch version for my bathroom fan.Another good use for this is if you are, like me, running out of capacity on your Hue Bridge. For instance, I have 4 GU10 Hue LEDs in my bathroom, so will replace them with normal dimmable bulbs and deploy one of these beauties to control all 4 so that I free up capacity for more Hue bulbs where I want the colour or white ambience bulbs. Once I had installed this where I planned I am planning on installing downlighters in my bedroom, and this will save a lot of Hue Bridge capacity (and a lot of money on bulbs!).

Great – but had to read the reviews to figure out installation
These work great once you work out how to install them. But even though theyâre advertised as âno neutralâ, it isnât very clear that you still canât seem to install them in a standard UK light switch without a neutral wire, or at least not without doing a âbypassâ, which I think involves purchasing another item from Samotech to wire into the ceiling – but the instructions are pretty unclear about this, or at least they are to my non-electrician eyes!In the end, to make life easier, I just wired the Samotech switch above the light itself in the ceiling so I could use the neutral wire, which was easy enough. I then used a wago clip in the original wall switch so the live wires were permanently âonâ, covered it with a completely flat blanking plate (80p from an electrical shop) and screwed a Philips Hue smart button over it. Works pretty well and looks neat enough.I also bought the Samotech ârotary dimmerâ switch for my kitchen. That was much easier and went into the wall switch without issue despite the lack of neutral wire. Not sure why that one works fine in the wall switch and the others donât – but again, not an electrician!The switches all paired fine with my Hue bridge, but for the SM308s, I had to bring the hub right to where Iâd wired in the switch and press the âresetâ button 5 times on the switch itself, while it was live. So make sure you pair them before you put them somewhere inaccessible. May be easier to plug them into the wall first to pair and then wire them in. I (very carefully) used an old extension lead wire to power the second one so I could pair it before it went in the ceiling. Needless to say if this all sounds intimidating, you should hire an electrician, or stick to the hue light bulbs.Overall worth the hassle to make this one off investment rather than needing to keep buying bulbs indefinitely, but it does require some planning.

Works great with hue… once paired.
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.

Apple Homekit / Philips Hue compatible
These are great for when (1) You have lots of lights to automate across a dual gang switch – use one SM308-2CH to control say 20 or 30 lights (much cheaper than replacing each bulb with a Hue) (2) have a dimmable LED light where you can’t use a Philips Hue bulb (e.g., from Tom Dixon that uses an integrated LED)- use the SM323v2 behind a faceplate or SM309-S in the attic/ceiling (3) you want to control something like a bathroom fan on voice control – use SM308-S with a standard switch.If you use the SM309-S (dimmer) you will need a switch with a reactive switch or just use the SM323v2 but you may need to buy a new faceplate.Do pair these close to the Philips Hue hub first and only then fit them in your attic/ceiling. Do note that the two Channel SM308-2CH appears as one light in the Philips Hue app but if you selectr it you can then see both channels. However in HomeKit this shows as two switches straight away.These work flawlessly with Philips Hue and Apple HomeKit for iPhone app and Siri voice control.

Easy setup but âclicksâ when used
The device produces a click sound when the lights turn on or off. Must be a relay, but itâs quite loud and not suitable for my intended location. Setup was easy with hue – just add it as a new âlightâ and itâs found right away

Ich habe den zigbee dimmer. Dieser funktioniert super. Hab ihn ohne Probleme mit meiner Amazon Echo 2 verbunden und jetzt kann ich den Esstisch per sprachbefehl dimmen. Wirklich klasse. Die kleine Box hat sogar unter den Lampenbaldachin gepasst, perfekt. Der Preis könnte aber etwas günstiger sein ð

Odio e amore, perfetto come sostituto per un relè passo-passo della Finder (che utilizza il segnale neutro per la parte di pulsante) e l’utilizzo di una lampadina dimmerabile, non sono mai riuscito a farlo funzionare correttamente con un telecomando della Philips HUE (sembra accoppiarsi, ma poi il risultato è che la lampada diventa ingestibile, con un fastidioso lampeggio infinito che si blocca solo tramite la forzatura del reset) ne l’uso con l’access point Zigbee/WiFi della stessa marca non è ottimale (la App di gestione è veramente discutibile).Provato ad utilizzare con un Echo Plus, ha funzionato giusto un paio di ore per poi venire sempre visto come off-line.L’ho tenuto perché funziona perfettamente con il pulsante da muro della Bticino ed è assolutamente silenzioso (un’altra cosa rispetto al fastidioso rumore che faceva il vecchio Finder), cerco che il costo superiore a â¬35 non rispecchia la qualità del Zigbee.

Est bien compatible Philips Hue.Il faut juste savoir que l’appairage se fait en mode Touch Link avec la base Philips Hue (donc il faut trouver une lampe et connecter les fils dessus pour l’approcher de la base et faire l’appairage)Ensuite, fonctionne super bien : est reconnu comme une lumière avec reglage d’intensité et on peut l’associer sans probleme à un smart bouton Hue.Par contre, l’autre entrée permet de connecter un bouton poussoir et pas un relais contact sec qui viendrait d’une autre commande d’ouverture type telecommande de portail, et c’est dommage.Mais bon, la doc explique bien que c’est pour un bouton poussoir (donc il faut une impulsion pour allumer ou éteindre)…Bref un tres bon produit, pas tres cher. Et à part Samotech, il n’y a pas grand monde qui fait ce genre de produit permettant de controller des lampes LED 220V via Philips Hue. (il y a aussi un allemand qui le propose, mais c’est plus cher)Et en plus, la portée sdu Zigbee est très bonne (dans mon cas, le module est pres du portail pour gerer un éclairage, à 50 metre de la premiere lumiere Hue qui est en intérieure. Couplée avec un detecteur de mouvement Hue)

Lo uso para controlar una guirnalda de bombillas en la terraza.No tuve ningún problema para incorporarlo a la app de Hue.Compré el modelo compatible con HomeKit (OJO! Que no todos los modelos son compatibles!). Si es lo que buscas, ten paciencia, aunque le cuesta unos minutos se sincroniza perfectamente y funciona sin problemas con Siri.No le encuentro ninguna pega, repetiré seguro.
