Just wanted to pass on my thanks to all who have contributed to this thread. I’m still working through some of the idiosyncrasies (like pre-heat vs on vs power level) BUT good Lord you saved me years!
I’m not seeing anything with a bit of searching showing ESPHome supporting the WBR3. Everything i’m seeing still requires replacing the WBR3 with an ESP. Any links?
Edit: Found a pull request that hasn’t been approved @ LibreTiny/RTL8710CM, etc. by nmschulte · Pull Request #7861 · esphome/esphome · GitHub
https://docs.libretiny.eu/docs/status/supported/#tuya-inc
On this page the WBR3 has a little information icon next to it (unfortunately can’t copy/paste the text) that brings up a tool tip specifying you can flash it as a generic-rtl8720cf-2mb-992k board, unless I misunderstand what the tool tip means.
Maybe this is out of date now, but when I try to install this through YAML, it complains about “platform: switch” and claims only “platform: binary sensor” is allowed.
Took me a bit to figure out the new formatting for local tuya template. And had to add a letter in front of the level numbers to avoid the “Failed to perform the action…” error.
Here’s a working template yaml config
Paste into a file located here:

I just went through the process of adding an ESP-12 to the controller board and getting it working with ESPHome. I documented the process here if it helps anyone.
Important note: I found that the mains neutral is connected directly to the low voltage ground plane. So you must never plug the device in while connected to any external low voltage components, such as a UART adapter! I fried mine while trying to dump the config on the WBR3.

Thank you @nevets27 , you saved me so much work!
I just purchased a single-sided mattress pad, and as this is the only place I could find documentation of the data points for LocalTuya, I wanted to pull together what I have been able to work out thanks to other posts in this conversation and some trial and error on my own.
13 Seems to always report 0
14 Master Power
20 Heat Level — It’s valid inputs are “level_1;level_2;level_3;level_4;level_5;level_6;level_7;level_8;level_9;level_10”
24 Pre-Heat — This will activate the preheat function and power on the mattress pad, regardless of the Master Power setting
26 Auto-off Timer — Note that “Stay_On” is simply 24 hours “30m;1h;1h30m;2h;2h30m;3h;3h30m;4h;4h30m;5h;5h30m;6h;6h30m;7h;7h30m;8h;8h30m;9h;9h30m;10h;Stay_On”
28 Auto-off Countdown — A value in seconds that shows how long until the Auto-off timer reaches zero
102 Pre-heat Timer — A countdown in seconds until the mattress pad switches from full-power to the set temperature level
103 Safety State — This either reports “45_Minutes_Before” or “User_Confirmation” and shows the state of the safety confirmation.
Normally, if the mattress pad is powered on remotely, someone must physically press a confirmation button on the controller within 45 minutes; otherwise, the mattress pad will limit itself to a heat level of 4. However, if the unit is powered up by interacting with any control other than the Master Power switch, it bypasses that limit and allows you to set the heat level to whatever you prefer without then needing to interact with the controller.
