I purchased three of these to control some exterior lights. The build quality was great and they installed with ease. By the way, it's not listed anywhere, but in case you're wondering the depth the switch required inside the electrical box is slightly over 1.25 inches (plus wires). This is important, since many electrical boxes don't have a lot of space. The switches came with Tasmota 12.1, which I was able to easily upgrade to 14.1. For the person who received switches with version 6.3 and failed to upgrade to 12.1: be aware that a direct upgrade is not possible. See the tasmota upgrade documentation; you'll need to go through several version upgrades to get to 12.1. I use my own scripts with cron to control the lights, so I can't speak to Home Assistant or other automation platform compatibility. But the HTTP interface to the switches works perfectly. I'm able to turn them on/off, set the dimmer level, and get the current status. The response time when executing these commands is instantaneous. The one negative I have is that the dimmer range is not very good. I think this is because I use LED lights and this switch has leading-edge dimming. When the dimming level is set to 45% the lights are basically off. 50% is barely on. Martin Jerry makes another switch, the US-SD-TC01 which has trailing-edge dimming, that is more suitable for LED lights. I should have done more research and picked those switches for my application, but that's on me not the switches, so I'm not going to take away any stars for that. Plus, I just set the lights between 50% and 100% instead of 0% to 100%. Overall, I'm quite happy with these switches in the short time I've had them.

Really glad to see Martin Jerry supporting open firmwares. They have good quality switches, and the setup process and usage is so much better with Tasmota. ESPHome was easy enough to flash, and works great. The only hiccup is that you have to be sure to flash Tasmota minimal before flashing your ESPHome firmware. After flashing, you might need to power cycle the switch to get dimming to work properly. Hardware wise, the buttons have good tactile feedback and aren’t mushy. The LEDs are a good brightness for most places, and are really nice for finding the switch in the dark. By default, the ESPHome firmware from the esphome-devices website has the red LED on when the switch is off, which works well.

this device was easy to install and setup in Home Assistant but unfortunately it failed yesterday after 3 months from purchase. Sent an email to manufacturer to see if they will warranty it

Works great. Nice to have it preflashed and work with HA out of the box. I wish the fade and speed feature of tasmota worked with it though. The lights always fade on and off and there is no way of controlling that experience.

Well, it is a dimmer switch. For the price, it feels cheap considering other Tuya switches that could easily be converted to Tasmota. I would say it is not worth the money.

I own at least a half a dozen of these switches (most are the old style with out tasmota). I have put esphome on all of them. The old style requires you to solder wires and manually flash which was a pain, but these tasmota versions are much easier. A note for people switching to esphome, the only firmware that will fit in the initial conversation to esphome is a fully stripped down version of esphome with only the Ota and wifi components enabled. After initial upload, then esphome can flash a full version over the air. There are plenty of Martin and jerry yaml configurations on internet right now. In terms of durability, they are quite good. I have had two of these switches (non tasmota firmware style but same hardware) for nearly 3 years now and one of them has lost its "clickyness" but still works the same, just without the satisfying "click" sound. Wifi connectivity is very good, but I recommend static ip config to reduce chance of disconnects from homeassistant.

THE BAD - While this is a good dimmer, it's not a great dimmer. MJ still uses leading-edge dimmers rather then the far superior trailing-edge dimmers, but outside that, this is a great product. THE GOOD - Comes with Tasmota preflashed, so automatic win. The icing on the cake is the build quality, the matte screw-less non-branded faceplate, the great packaging, and the build quality [listed twice for a reason]. Many products use standards mouse button-like switches that have a very light, high-pitched quiet click as expected. The MJ switches have a nice heavy tactile sound and feel that at least give the impression of higher quality. I MUCH prefer this!!! With the LED lights I use, they do not activate unless the dimmer is above about 45%. This can be corrected in the Tasmota dimmer range settings. They can, however be dimmed down to about 2% if you start with them on first. This is the drawback to using leading edge dimmers and just can't be resolved. So, either know the limitations and adjust your code accordingly, or adjust the range to avoid it and just not dim as low. MJ, keep up the good work releasing preflashed Tasmota and consider trailing-edge in the future. Might cost a bit more, but a quality device is worth it.

I installed this in my office/workshop where I recently installed a large overhead LED light that at full brightness was just too much for working at my computer, but OK for doing electronics hobby stuff. This dimmer worked perfectly in that it tracks the brightness to match my light. In other words, 50% is right about what you would want 50% to be etc. Only slight complaint is that the unit is large and barely fits in a standard wall box. If you have multiple connections in your box it will be tight. The screwless cover plate seems pretty much useless so I just used one I had which fits fine. The light automatically integrated with Home Assistant as an entity and adding it to my dashboards was painless. Great value and performance so far, I hope it works reliably over time.
