core: Tuya fan (code fs) won't show speed options

The problem

I’ve bought two Tuya fan switches with 4 buttons: light and low/mid/high speeds. HA shows the light fine, but the fan entity only has an on/off switch (which places it in the last used speed).

Details from iot.tuya.com

• name: WiFi风扇灯
• category: fs
• Given the JSON below, this looks like a Tuya issue, since not even their IOT platform seems able to do the speed change? 🤦‍♂️ If that’s the case, any hint on how to report it to them?

Additional information

PS: the GH issue template needs some update - ~Settings > About does not show the exact version requested (with the core- prefix), nor the installation type, which might confuse some people. That seems to be available at the top-right option at the Repairs screen (which I stumbled upon at some other request, I would never think of looking for this there).~ Went ahead and PR’d it at #58933
