My understanding is that many IoT home control products get rebranded that are made by Tuya.
https://faceitsalon.com/wiring-diagram-for-a-feit-wi-fi-smart-dimmer-switch-collection/
In any case however it comes to be, many products are Tuya inside, that is, they work through the cloud-based Tuya management app.


This means when for example when you are sitting on your couch and it's getting dark and you want to switch on your living room light via Home Assistant, the commands have to go up to Tuya's web site and then back down through your gateway to your living room. Since this offends my sense of efficiency and privacy, I want to install ESPhome on all my Tuya devices.
For me these are advantageous when installed in 3 way circuits and my house has a lot of those. You can put a dimmer at each end or a regular switch at the far end. Now that they are down to $10 and Decora 3-way switches are $4 and 4-way switches are $15 it's not really worth replacing a toggle with a dumb Decora in some places, like my dining room and stairs.  
I bought them with this in mind.


== TWYE2S cpu ==
When replacing a switched 3-way set up you can use one each, dumb switch and smart dimmer. You can also put a dimmer at each end, you put each switch on line power and use the traveler to let them talk to each other.


Both of these devices (Martin Jerry and Feit) use a Tuya TWYE2S cpu module.
You can extend this to 4-way circuits, here is a picture someone posted: https://imgur.com/GIZwCqs This actually causes less confusion in my brain than conventional multipole switches. Sad perhaps? I think I might be able to replace the 4-way with a 4-way and have one dimmer + 2 switches.
I fried one for an S-01 switch so I ordered a kit on Amazon with 5 ESP12F modules and a programmer/breakout board. The programmer should be handy. I could probably yank a module
off some other widget but geez, the modules are about $2 each.


The ESP12F has more signals brought out to the edges but they won't interfere with anything when replacing a TWYE2S. An ESP12S is a match and is a tiny bit smaller too, but I like having the

For me these are advantageous when installed in 3 way circuits and my house has a lot of those. You can put a dimmer at each end or a regular switch at the far end. Now that they are down to $10 and Decora 3-way switches are $4 and 4-way switches are $15 it's not really worth replacing a toggle with a dumb Decora in some places, like my dining room and stairs.

When replacing a switched 3-way set up you can use one each, dumb switch and smart dimmer. You can also put a dimmer at each end, you put each switch on line power and use the traveler to let them talk to each other.

You can extend this to 4-way circuits, here is a picture someone posted: https://imgur.com/GIZwCqs This actually causes less confusion in my brain than conventional multipole switches. Sad perhaps? I think I might be able to replace the 4-way with a 4-way and have one dimmer + 2 switches.

Tuya usage

Basic 'normal' set up

  1. Register a Tuya account and log in.
  2. Add the Tuya integration to HA.
  3. Install the Tuya "Smart Life" app and launch it. (There is also a "TuyaSmart" app, both are supported in HA, I don't know the difference.)
  4. Power up the new dimmer.
  5. Configure it with Smart Life.
  6. Now it will just pop up in HA and you can treat it like any other HA device.

Reflashing

I have not succeeded in reflashing any of these yet. I pulled one apart to learn how to flash it and I think I fried the CPU.

It can be done by removing the WiFi chip or by attaching wires and cutting a trace. I tried removal and failed.

Notes on removing the ESP from the dimmer are here: https://community.smartthings.com/t/costco-cheap-feit-smart-dimmer-wifi/208142 Also note you can replace the ESP board with an ESP-01 if you break one.
