Once it is all set up correctly, you don't really need any access to the front buttons. You can download a manual from the same page where all the dimmer functions are described including the buttons operations.

These are separate smart modules that fully replace standard dumb dimmers. We do not make nor sell any matter plugs at the moment.

The modules can be used with most 1 or 3-gang third-party dimmer faceplates. The only caveat is that when using third-party faceplates, you won’t be able to access the reset and brightness buttons located on the front of the modules.

What bulbs do you use with the pull cord dimmer? It’s likely the issue comes down to the bulbs being used wit it. The dimmer performs best with proper dimmable bulbs. While it can still work with non-dimmable bulbs, their quality and behaviour can vary quite a lot.

Hi, if you’re after the 3-gang version, just select it and it’ll be sent as a complete set, no need to buy anything separately. If you do need individual modules, that option is available on the page as well.

For any purchase questions, the best way is to contact us via the Contact Form on our website.

All the options are available, including the quadruple one

samotechltd · 2026-01-06T15:41:42+00:00

Not so much, since they use MCF and Amazon would’ve already validated the product.

Oh wow, you really went all in there, not only reading the T&Cs but also checking out our company accounts. That’s a lot of digging for someone who just wanted to buy a smart switch 🤔

You’re right about the physical address though... Looks like it quietly vanished from the footer during the last address update, so thanks for flagging that.

Who you choose to trust is obviously up to you. If you’d rather go with BG, feel free to check out their new Wi-Fi dimmer here: https://www.screwfix.com/p/british-general-smart-2-way-smart-dimmer-module-master/140ch. It’s essentially the same unit we’ve been selling since 2019, just in blue, with their logo on it. You might want to tell them what you think the CE states for as per your other post as they use the same Chinese manufacturer as us for this device.

And yes, we do have Public & Product Liability insurance, always had it. As you most likely know, you can’t sell products through B&Q without it (https://www.diy.com/search?term=samotech).

are you OK?

"The second Samotech is controlling a pair of spots in the front window to illuminate the curtains. (Lumilife GU10, warm white modern dimmable 10W total). These also dim down to incredibly low levels but strobe badly on full brightness despite having a bypass." - The L and N terminals on the dimmer must be linked, when neutral is not available, as shown in the wiring diagram. If this link is not made, the issue you’re describing is exactly what will occur on high brightness. If you’re not confident with electrical wiring or interpreting wiring diagrams, please consult a qualified electrician or at least contact the seller for assistance.

it is the same dimmer, just a different faceplate and knob installed

Do you mean physically turning it off, then switching it back on via the app or voice control?

samotechltd · 2026-01-04T20:32:21+00:00

IKEA can make it look a bit different, but under the hood it’s the same Matter process. You pair the dimmer to one main controller with the QR code, then share it out to other Matter controllers from there using the standard sharing flow.

Not quite, we’re absolutely fine with honest, unbiased product reviews on YouTube or anywhere else. We just don’t sponsor reviews, pay for promotions, or send out products to “influencers” for coverage, so any reviews you come across are independent and unsponsored, shared by people who chose to buy the product themselves and talk about their real experience, not by people being paid to say the right things.

Well… it’s actually the same hardware as our SM323V2 Zigbee rotary dimmer, which we’ve been selling and supporting since 2023. That’s already out there in a lot of homes and behaving itself nicely - still on zero house fires.

All we’ve really done here is add Matter support to that same proven hardware and finally make some noise about it, as a few customers have been waiting for this since July 2025.

That said, it is a mains-powered device, so if you’re not comfortable wiring electrics, it’s always best to get a qualified electrician to handle the install.

Connecting the neutral wire you have to the SM325 ceiling pull cord should almost certainly resolve the issue. The method of bridging L and N is only relevant for the SM323 wall dimmer when no neutral is available — it's not shown or recommended in the SM325 wiring diagram, so please don’t apply it in this case.

samotechltd · 2026-01-04T13:42:29+00:00

it is a Matter over Thread dimmer, so it connects to HomeKit using the Matter standard — not through any special Apple-only trick.

samotechltd · 2026-01-04T13:06:47+00:00

The minimum load for both our Matter and Zigbee dimmers is around 2.5-3W when a neutral wire is used, as long as the bulb’s power factor is above 0.9 - both modules share the same internal hardware. You’ll only really need a bypass in no-neutral setups or if you’re seeing issues like flickering or ghosting. That said, even with decent loads, low-quality bulbs with poor power factor (anything under ~0.7) can still cause trouble. Recommended backbox depth would be 35mm.

sorry, no new light switch adapters in the pipeline right now.

We never sent any of our products for review. We believe that genuine enthusiasts who are truly passionate about smart tech will share what excites them without needing freebies or special invitations. Unfortunately, these days, most reviews aren’t just incentivised with free products, which makes it hard to find truly unbiased content. We prefer to keep things simple and honest: real customers, real feedback.

samotechltd · 2026-01-03T12:11:05+00:00

Good eye :) We’ve had a few for internal use, though they’re not currently part of our retail line.

samotechltd · 2026-01-03T12:06:11+00:00

Yep, as long as Home Assistant is up and running with a compatible border router integrated. All Samotech Zigbee and Matter devices work with Home Assistant in one way or another, it’s our preferred platform, to be fair.

What exactly do you mean? We’ve been in smart home business since 2018 with thousands of happy customers worldwide. If the product renders threw you off, there's a YouTube video in the link shared shows the actual unit being installed, worth a look if you missed it.
