Smart Dimmer Switch by Martin Jerry | New, Trailing Edge Dimmer Light Switch, Voice Control by Alexa, Google Home, SmartLife App, Needs Neutral Wires, 2.4G WiFi Only

Doesn’t work with my LED lights
My ceiling lights are dimmable but they flicker with this switch.

Great dimmer but non-intuitive touch control
First, let there be no doubt: I love Love LOVE trailing edge dimmers for LED lighting, and these latest models from Martin Jerry seem like pretty high quality to me. I would have given them 5 stars if not for one thing:You control this dimmer manually by touch. There are no moving parts. To turn it on and off, you touch the small lighted spot near the bottom. To control the dimming, you touch or slide your finger on the vertical stack of LEDs. The dimmer control is obvious enough, but the on-off is not intuitive. I’m not too worried about me, and the griping from household members settled down after a while. But I did a test with some of those household members. “Turn that light on.” They all failed to get it that they should touch the little lighted spot until I told them.I believe in the smart home principle that others have said: You should still be able to operate everything manually in an intuitive and non-confusing way. I wish MJ made these new trailing edge dimmers with controls similar to their previous generation.Lest we forget, I repeat that the actual dimmer function, including automation, is excellent. These are Tuya-based, so they use the same cloud infrastructure as many other Chinese brands. It’s the trailing edge technology that sets them apart. (If you are looking at a smart dimmer that does not say it’s trailing edge, then it is almost certainly leading edge; in which case, your success with any particular LED lights will be a matter of luck.) No such worries with these latest MJ dimmers.

Very precise dimmer for LED lights
Re: MartinJerry touch dimmer switch The fine tuning capabilities of this dimmer are switch slows you to customize the minimum light level setting per the requirements of a particular LED light (or group of connected lights).Additionally, the company provides truly outstanding customer service.

Easy to use and great quality.
I really like these Martin Jerry smart home switches. They have a sturdiness to them that some other brands lack. I’m a lot more comfortable installing this style of switch over the previous generation.These are TUYA based switches that work very well with Smart Life. I used to reflash these to use them on an MQTT based smart home platform but I’m migrating away from that complexity and trying to use Smart Life for everything.I have a 2.4 GHz TPlink access point that I use for all my smart home switches and cameras. This network is dedicated to only smart home items and I find I have the least amount of trouble that way. My home has standard sheetrock walls and plastic outlet boxes.Installation for the power side of this switch is pretty standard. The MJ switch feels substantial and while it’s a bit big it’s still easy enough to connect everything and shove it into a well organized electrical box. The key to success there is to get as much to the back of the box as possible.Smart Life finds these switches easily enough and can control them right away. Alexa on the other hand sometimes take a bit. I find Smart Life needs to refresh before Alexa will pick up on the name of the light or switch and allow you to start using voice commands.I’ve had no issues with flickering when dimming but I didn’t have any previously either.I recommend MJ switches for sure.
