    Finally a Tasmota 3 way Dimmer and it works great
    MJ promised to get out a 3 way dimmer flashed with Tasmota and here it finally is! So if you are looking for 3 way dimmer with Tasmota pre installed this is the ONLY manufacturer making it. If you don’t know what Tasmota is you probably can get by with their standard offering but if you want to not have your device on the “chinese cloud” then this is the answer. Easy to get on my network in the standard Tasmota way. The dimming itself works great (I have mine on 7 down lights and there is no flickers a low dimming) and the rotory switch is nice and the dimming level easy to see plus it has a “night light” feature.The only thing that gave me pause is that their wiring diagrams do not have the load in the same box they way mine is wired. So you still have to power the “live” but then then they send out line via one of the two travellers. In my setup the white wire of my 14-3 is supposed to get power but instead since it is the common at the far 2 way it’s just reverse it has the power for the lights so I hooked that up to my lights load and it works great. BTW this is a 4 way setup if you were wondering if you can do a 4way (three switch) setup you can. So if they provided a diagram for my setup that would be helpful for those not familair with travellers and 3/4 way switches.So yes very happy. Get on if Tasmota and Home Assistant is you deal!

    Limited customizability and doesn’t get very dim.
    Works well but 2 complaints:1. The brightness range is pretty bad if you prefer low light. 1% brightness is more like 10% on my Shelly Plus Wall Dimmer. Given that the whole reason I got this was for making finer adjustments in the dimmest light range, that’s a pretty big ding against it.2. You can’t customize much with Tasmota because the WiFi chip that Tasmota runs on isn’t actually running the show. There’s a separate Tuya MCU module that executes all the logic internally. All that Tasmota can do is manage parameters like brightness range. If you want to do something like connect the night light & button to your home automation system so that it can be turned on and off by an automation, you’re out of luck. That circuit can only be toggled by physically interacting with the device. I thought the whole point of having a smart device was so that you could control it remotely, but I guess not in this case. ¯_(ツ)_/¯

    Excellent customer service.
    I originally thought that I had a defective switch because the switch wouldn’t turn off during pre-installation testing. After contacting Martin Jerry, including a Facetime video conversation, I realized that the traveler wires must to hooked up to the load for the switch to work properly. Overall MJ is a very good switch and their people were a joy to work with.

    The older one is better
    This new model has a smooth dimmer wheel which makes it a pain to turn.The old model had ridges all the way around and was perfect.Why did you make it worse MJ?On the other hand MJ is making a great move by supporting Tasmota pre installed. All IoT companies should do that. Vendor lock-in is not your friend in IoT.

    nice . nice price , but 1 problem
    the dimmer is very nice .. the led lights help you find it in the dark. it has a circle/knob that you can use to control manually. now the downside is connecting it to the app .. I’ve had it for 3 daya now .. still no luck.
