Fan control is difficult to use

[Mbuckley0]

Describe the bug
I have this smart switch with a light and fan control on it https://www.bunnings.com.au/deta-grid-connect-smart-fan-speed-controller-with-touch-light-switch_p0098815. I have managed to connect this with tuya and homebridge and the light switch works great but I am having some issues with the fan switch. The fan only has 3 speeds but the home app is showing the fan control as a slider and if I turn on the fan using the slider and then slide it to 0% the fan doesn't turn off.

Expected behavior
The fan accessory should have an on/off switch as well as 3 preset speeds if possible.

Thank you for your feedback, we will solve this issue soon

We can set minStep for accessory then 3-level fan can only slide to 0%, 25%, 50%, 75%, 100%.
If use switch instead of slider, there will be 3 switch with relations, if one on then others should automatically off, such logic make code more complicated maybe.
Please try 0x5e#37 if it solves your problem.

@0x5e How do I configure the minStep for the accessory? The on/off functionality seems to be working better with this change.

The code will configure it self, no need to configure manually. @Mbuckley0
