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
- Register a Tuya account and log in.
- Add the Tuya integration to HA.
- 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.)
- Power up the new dimmer.
- Configure it with Smart Life.
- 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.
