Finally got back to this. Originally I used the Treatlife app with this switch, so I couldn’t add it to HA via the Tuya Integration. I factory reset the switch and then added it to the Tuya Smart app. (FYI to factory reset, hold the light switch for 5 seconds. The WiFi light within the light switch will begin flashing quickly. Hold the light switch again for 5 seconds. The WiFi light within the light switch will begin flashing slowly, indicating pairing mode is ready).
Went through all the instructions to setup the Tuya Integration, which were great. In the end, my fan/light switch device was successfully added to HA. However, just like so many have mentioned here, I only have two entities, as shown here:

When I activate the fan toggle, it sets it to Level 1 in the Tuya Smart app, and the fans speed at that level (very, very slowly). Any ideas on how to get all 4 levels?
@LAYGO , when you say “it’s working”, are you able to control the 4 speeds of the fan? If so, how does yours look as compared to mine?
Thanks,
