Add function to set "Warm" and "Heat" mode
**Describe the idea or improvement**
I have the Xiaomi Smart Heater Fan and it has two main speeds or heating modes, warm and heat. Warm uses around 1200 watt and heat uses the full capacity of 2000 watt. In the Mi Home app you can adjust this but not in Apple Home. Would be great.

**Describe the solution you'd like**
Set warm and heat mode
