How to integrate TQ-IW3+1 (3 Light + 1 Fan) Retrofit Module into Home Assistant?

Hi everyone,

I recently got a 3 Light + 1 Fan Retrofit Module (Model: TQ-IW3+1) and I’m looking for the best way to integrate it into my Home Assistant setup.

Device Specifications:

  • Model: TQ-IW3+1
  • Load: L1, L2, L3 (6A) | Fan (10A)
  • Connectivity: Wi-Fi 2.4 GHz (802.11 b/g/n)
  • Firmware: Likely Tuya-based.

What I need help with:

  1. Has anyone successfully integrated this specific model using the official Tuya integration or Local Tuya?
  2. Does this module support flashing with Tasmota or ESPHome? If yes, does anyone have the GPIO pinout or template?
  3. Are there any specific configurations needed for the Fan speed control to show up correctly in HA?

I’ve attached a photo of the device for reference. Any guidance or links to a setup guide would be much appreciated!

Thanks in advance!

You’ll need to open it up and check which chip it’s using. It’s likely beken so you can flash esphome and also retrieve the pinout from the stock firmware dump
