Hello, my first post here, although I’ve been coming here for a year or so to read about different items.
I flashed a lamp with ESPHome. It uses Tuya MCU and it has required a bit of tinkering to find the proper settings. While I flashed slightly different configurations, the RGB+CT light controls disappeared from HA and they refuse to come back. I can only set the lamp mode from the interface. I need help bringing back the light control to the UI.
A bit of background:
I have a couple of lamps I got on different occasions that looked very similar. They are different brands and I bought them at different times. I decided to take a peek to see if I could flash ESPHome on them and found out that the circuits are identical. Same chips and everything: This is what they look like on the inside
They both have a BK72XX module inside (WB3S), which I removed to flash ESPHome. This is my YAML

As I mentioned before, the light control appeared and controlled the light well through multiple iterations of my trial-and-error process, but then it became unavailable and never came back.
What I have tried so far:
- Deleted the unavailable control from the UI.
- Deleted the ESPHome device and added it again from HA by pasting the YAML. This only brought the mode selector back.
- Looked for unknown/orphan entities without luck
- Flashed a version without any controls to the device and then readded the controls. Only the mode selector came back
- Deleted the device, let HA discover it. Added it again. Only mode selector was added.
- Reloaded HA
- Rebooted HA
The light responds to its buttons and I can see the settings changing in the logs, but I cannot control them from HA. (Other than the mode).
Any help is welcome.
As closing notes, these posts were very helpful for me to get to where I am:
TuyaMCU - Tasmota to get the data point identifiers
(Will add two others as a reply. I am limited as a new user)
