I didn't need the dual function, but works great with my Zigbee network. Easy to add and stable. I us it to control my pool lights so I have to cycle it several times to set different colors. This has worked better than my Z-wave switchs that kept having delays in responses.

Easy to use and reliable. I’ve installed these in two houses now.

Bought the no neutral wire 4pk. These work great with Home Assistant. I am using ZHA and SONOFF Zigbee 3.0 USB Dongle Plus V2 and they were discovered/paired with no issues. They are discovered as a light, not a switch but functionality seemed the same either way. I did add the ZHA config to make them rediscover as a switch without issue.They fit well along side other switches in 2 and 4 gang boxes. (see pics)I did have a hardware issue with one switch randomly turning on throughout the day. Contacted MartinJerry via the reseller messaging and they were very responsive and have shipped out a replacement. Excellent customer service you don't see much today.Highly recommend this product for home automation with Home Assistant and highly recommend Martin Jerry.

Really disappointed with this. The first thing I noticed is that if I set the dimmer for the night-light to a low amount, it flickers like crazy. It basically needs to be all the way on or all the way off.Then I noticed that the switch will randomly decide not to turn on or not to turn off both manually or using voice commands through my Alexa. It will work great one moment, then later it just simply will not work at all or it will have an insane amount of delay. Literally minutes after I ask Alexa to turn it on or off it will finally do what I asked. Sometimes it won’t respond at all.Then I found that when I secure the switch in the junction box it twists the switch frame (or something?) which causes the switch button to get stuck.I don’t know if the issue is that the relay inside is getting pinched and cannot move or if the electronics are just junky. I hadn’t seen them before, but after reviewing the comments for this, I now see other people having similar problems.

Switch causes LED lights to buzz horribly loud, 3 LED lights combined less than 75 watts. Also the zigbee integration was super laggy although connected instantly to my home assistant. Will resort to running new wire with a neutral to buy Kasa switches as they work perfectly everywhere else in my home.

The Good: It does work with Philips Hue, it does not require a neutral wire to install and already comes with some wire connectors. It was also easy to install.The Bad: Made VERY cheaply. Cheap plastic, cheap internal wiring. Also the box housing barely fit within my electrical switchbox as it is super bulky. I will need to buy a new electrical switch housing and do some major remodeling to the wall to get it to fit flush.There are no instructions on how to install this via a Philips Hue hub, so I'll include this here:To get it to work with Philips Hue you will need to add it like you would a normal lightbulb, NOT AS A SWITCH. Just press and hold the teeny tiny Zigbee button to the left of the light on the face of the switch, wait for the light(on the switch) to blink then add it like normal.

After installing 14 smart switches in my house, the only two I had left to do did not have neutral wires, so I ended up ordering these No neutral 2 pole RB-ZB-S01-P1 switches. I did eventually get these installed and working, but at first I was very confused on how to get them working because they don't come with any instructions and the instructions you find here on Amazon either from the AI bot or from other instructions in the comments do not work. The main thing that is incorrect is that you do not repeatedly push the switch to get it in pairing mode. You hold the switch down for 5–8 seconds and then the red LED will start flashing quickly so you know that it's in pairing mode. The AI bot told me to push it rapidly 4 times, and someone in the reviews said you have to push the switch 6 times rapidly. Neither of those are true, again you have to press and hold the switch down until the LED starts flashing.Also, you have to have either the Zigbee Hub 3.0 or some other hub. My Alexa Echo worked for me. Initially I was trying to add these switches to my Smart Life app because both of the other types of smart switches I have all work flawlessly with smart life and do not need a hub. All my other switches I would first add them to Smart Life and then the Alexa app would immediately pick it up also. With these, I had to add them straight in to the Alexa app. In the course of doing so, Alexa app will ask you if you added it to the "Martin Jerry" app.I have no idea if MJ has their own app or not, but I didn't want any more apps on my phone for smart devices if I can help it (already have 4) so I told Alexa that I had already added it to the MJ app and that I could turn it on/off with the MJ app. That worked and allowed me to add it straight into my Alexa app, and it works just fine.Maybe this is the way all smart switches with no neutral work, so I only dinged this switch 1 star. Other than it being more difficult to set up initially, and not having come with instructions, these switches seem fine so far.Also, since these don't come with instructions, The wheel on the top of the switch BEFORE you get it synced to your hub/app seems to change the LED light on the front from red to white. This is not the case. When the red light is showing, that just means the switch has not been paired to a hub/app. Once it's added, the red light disappears and the wheel then becomes the way you adjust the brightness of the white LED light. You can turn it all the way down so that the LED "night light" is off, or you can spin it up to full brightness. Lastly, I'd have preferred if they had made the wheel accessible from the front of the switch so I can adjust the brightness of the LED nightlight on the fly. They could have made the switch smaller since the switch doesn't need to look like a rocker panel switch and could just simply be a button you push. Then this would leave room to add the wheel to the front of the switch.I believe (from something I read) the nightlight can also be controlled in the Smart Life app but I was unable to get the smart life to detect and add these switches. These switches will only stay in pairing mode for about 20-30 seconds which is not enough time for smart life to detect and add the switches. Even when I could get smart life to detect the switch, it would fail to add the switch because the switch would drop out of pairing mode before smart life was done adding it, causing it to fail to add the device.In conclusion, Would I buy them again? Yes, but only because they are the cheapest option I could find for no neutral switches. Otherwise, I would have probably tried something else that came with instructions and didn't require a hub to work.

Wanted a 240V smart switch and this is exactly thwt

Successfully converted to Tasmota OTA. Applied the MJ-S01 template. Integrated in my MQTT setup + Node-RED, works like a charm! Best of both world: Martin Jerry cloud for non-technical people, able to convert to Tasmota OTA for people like me!

Excellent switch. Easy to install and does what is expected.

Easy to install and linked with Alexa right away without difficulty. Great product for the money

I bought my first Martin Jerry Switch that I installed in my kitchen for pendant lights over the island. The switch is well made and it was very easy to install. My wife was happy because now she can use her phone to change the brightness to her liking. Because it worked so well, I bought a second switch to control the ceiling pot lights. We are very happy with this product.
