Smart Ceiling Fan Control | App, 4-Speed, Voice by Alexa & Google, SmartLife App, Needs Neutral, 2.4G WiFi

I purchased this wifi fan switch so that I could control the switch via smartThings (samsung) as I have my thermostat (Nest) on there too. But first, installing this thing. I haven't really dabbled much with electrical installations, but figured this one wasn't too difficult after opening up the switch box. Just remember that if you see 3-5 white neutral wires all bundled together, just add this switch's neutral connection to the whole bundle! I thought I could just peel one of those neutral wires off and it definitely did not work until I just added it to the bundle. Hopefully that helps someone.So back to the SmartThings integration. You'll first need to d/l the SmartLife app and then click 'Scene'. Then find 'Tap-to-Run' at the top. Create two tasks. The first is Fan Switch: ON. The second is Fan Switch: OFF. For example, you should see this, "If Launch Tap-to-Run Then Ceiling Fan (Or whatever you called your switch) Fan Switch:ON". Once you've created these tasks switch over to SmartThings app. There, go to devices and add -> Add Device. Search for 'Smart Life' and then go through the next few screens to log into your Smart Life account where it will bring in your switch. If you didn't set a location/room for your switch you might need to select 'All devices' when you get back to your devices screen. You should now see the two tasks you created in smartLife brought in as devices. You can call the ON or the OFF task in any routine you'd like to set up. For example, I set up a routine to use the task 'OFF' when the state of the thermostat turns to cooling (AC Turns on). Good luck!

Be careful when ordering. Unlike older Martin Jerry items this non Tasmota version is NOT flashable to to Tasmota. Google does not always show both the Tasmota and Non tasmota versions when you are searching. So be careful when ordering that you are getting the one you want.

Installing this fan switch was a breeze. It was quickly recognized in the Smart Things app and Alexa picked it up automatically. Now this is what I call Internet of Things IoT. All of my fans in the house are getting this smart device.

I started with Leviton, it lost WiFi connection repeatedly. Other Martin Jerry dimmers I use for lighting do not lose WiFi often.Then I tried Treatlife. Great reviews, bad experience. Treatlife lost the Alexa link daily. Bye bye Treatlife.Then I found that Martin Jerry released a new fan dimmer, and I ordered my third device.Martin Jerry for the win! No WiFi dropping, Alexa is on the job constantly. No issues after one week.

If you’re comfortable working with Mains voltage, installation of this fan controller is super easy. There are only 4 clearly-marked wires to connect. Once powered, the fan controller should go into pairing mode (i.e., flashing red light). Start and log in to the Smart Life app on your phone with Bluetooth enabled and press “+” to add device, then just following instructions from the app. My fan controller and IPhone are on different VLANs so I had to add manually. But the process was still fairly straight forward. This fan controller works well with the Smart Life app. I can turn the fan on and off, and set fan speeds without problems.For Home Assistant users, note that this fan controller is not supported by the most current version (as of 12/20/2021) of HA and Tuya integration. However, I was able to add this controller using the Local Tuya integration. Unfortunately, I can only get the on/off function to work. Speed control doesn’t work despite my many attempts at configuring. Also, this fan controller uses the WB3S chip developed by Tuya, which is incompatible with ESP-based open source firmware such as Tasmota and ESPHome. So flashing is out of the question. Luckily, the WB3S is pin-compatible with the ESP-12F (see attached photos). ESP-12Fs are easily sourced and only cost slightly over $1 each. So if you don’t mind a bit of soldering, you can replace the WB3S with an ESP-12F flashed with Tasmota. DigiblurDIY has a video on his YouTube channel that shows how. This is what I intend to do.I’ve used Martin Jerry products for over 3 years, and have quite a few of their smart switches installed in my house. MJ devices ship with Tuya firmware and the Tuya Smart Life app for controlling. Like almost all other pre-loaded smart-home software, a big drawback of the Tuya ecosystem is that it requires the internet to operate. This is something that I really dislike. Data privacy aside, the idea of having to send a message to a cloud server from a smart phone just to control a device possibly located only a few feet from the phone seems ludicrous to me. To get around this, I flash all my smart devices with the open-source firmwares Tasmota or ESPHome, and control them using the Home Assistant home automation software. Using HA has the added advantage of allowing the output of one device to drive the input of another through automation. Tasmota and ESPHome are only compatible with microcontrollers made by Espressif Systems (e.g., esp-8266, esp-32, etc.). That hasn’t been a problem because until recently, most smart-home devices have ESP chips in them. All my older Martin Jerry devices use one of the ESP chips, and have work flawlessly with either Tasmota or ESPHome for over 2 years. One reason why I’ve been a big fan of Martin Jerry products is that their devices are easy to flash, and the company doesn’t discourage users from doing so. In fact, on many of their products, including this one, the company specifically mention on their web site product compatibility with Tasmota. (See photo of screenshot; note that the Tasmota link is dead now) Being a Martin Jerry product, I just assumed this fan controller has an ESP chip in it. Unfortunately, I was wrong. There’s currently a joint-development effort between Tuya and HA developers to produce a Tuya integration that includes local-control support of devices. Until then, I won’t be acquiring more MJ products unless I know definitively the product uses an ESP chip. It would be useful if MJ included this information on their product website.

Nothing great or bad. Does what it's supposed to do.

I have 25-year-old fans in my loft that worked on a wall switch. These worked great and were super easy to install.
