Trying to get RGB Torchier Floor Lamp working with Home Assistant

[sovamind]

I have an RGB floor lamp that I bought off Amazon but the manufacture went out of business and I can't find any information on it. I've figured out that it has an ESP8266EX chip and was able to install Tasmota on it using Tuyaconvert and it even auto-detected in Home Assistant.

Now the problem is that the configuration doesn't work. Home Assistant and Tasmota web-interface only show a toggle for on/off, which doesn't work. I tried using the template for "RGB floor lamp" that I found, but that doesn't work either and also doesn't show RGW controls, just on/off, which doesn't work.

I've since discovered that it is a lamp with a Tuya control module and was trying to figure out the commands using the guide here: https://tasmota.github.io/docs/TuyaMCU/ but am getting totally confused. I got as far as going to the console and pushing the buttons on the lamp and recording all the Tuya commands on the console, but I don't know how to get from there to a configuration that works in home assistant. I've even tried typing tuyasend commands at the console but none of them that I've tried have done anything.

If someone could help explain the next steps that would be great. I thought about reflashing with ESPHome (which I better understand) but apparently, I can't because Tasmota version is too high (v14) and there is no way to downgrade the version.

First make it work without even looking at HA. But how did you configure the lamp? In simple cases, you may have success with the command Module 54 to enable TuyaMCU mode, but that's what the entry for https://templates.blakadder.com/LDD-25W-D.html does.

To be clear, I'm not at all knowledgeable about messing with TuyaMCU (I avoid those devices like the plague), but I suspect that you did not understand the "TuyaMCU Config" part of the template page. Here's another lamp where such steps are spelled out: https://templates.blakadder.com/hugoai_HG02

What exact settings you need depends on details of your specific lamp.

Alright, I've finally come to the conclusion that Tasmota does not support the Tuya MCU in this light. I finally figured out all the functions (FnID) for each device pin ID. However, when I properly set all of them, the Tasmota main screen does not show appropriate controls. The documentation just sent me around and around and wasting HOURS trying all different combinations.

Thanks to SillyFrog's amazing JS helper tool (https://github.com/sillyfrog/Tasmota-Tuya-Helper), I was able to confirm that the functions and device pin IDs are correct. I can manually manipulate the values for each dpID and the light works exactly like expected. However, since the controls don't show up on the main page, they also do not show up in MQQT and I cannot use the light with Home Assistant.

The configuration that should work would be (description, fnID, dpID):
Power - 1,20
Mode - 26,21
Brightness - 21,22 [10 - 1000 integer]
Temp - 22,23 [0 - 1000 integer]
Color - 12,24 [JSON but Tasmota function 24 works]

Device Template #1 - No RGB Color Modes:
{"NAME":"Tuya Torchier","GPIO":[0,2272,0,2304,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":54, "CMND":"Backlog TuyaMCU 11,20; TuyaMCU 21,22; TuyaMCU 23,23; DimmerRange 10,1000;}

Device Template #2 - RGB Color Modes with bugs:
{"NAME":"Tuya RGB Torchier","GPIO":[0,2272,0,2304,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":54, "CMND":"Backlog TuyaMCU 11,20; TuyaMCU 26,21; TuyaMCU 21,22; TuyaMCU 23,23; TuyaMCU 24,24; DimmerRange 10,1000; SetOption20 on}

The only problem I'm still trying to fix is that only the power switch entity is controlable in Home Assistant. as light.tasmota. The rest of the 9 entities are just readable values like wifi, uptime, etc. Not sure why the dimmers and other modes didn't get auto-discovered but hoping I might be able to manually add them using the yaml files.

Functions that don't have Tasmota support currently:
Scene - dpID 25 [JSON similar to function 24]
Music - dpID 26 [0 - 86400 integer, seems to be microphone level?]
Control Data - dpID 27, [JSON that lets you set all values in a single command, ideally this would be used for control/MQQT]
Count Down - dpID 28, [JSON similar to above but values decrement by step every second, with loop around]

Below is a summary of the JSON from TuyaCloud which shows the details. Hoping that the Tasmota developers can add functionality to support the v2 modes and the scenes and music modes (not that I use them frequently, or ever?)

Oh, this is likely the same device but the template isn't present. I submitted the information so hopefully they can update this device page too. https://templates.blakadder.com/LDD-25W-D.html
