Enrich H801 tasmota python plugin with buttons

[pybypl]

hello,
As far as I know when writing python scripts we use switches and controls that comes with domoticz?
Although I want to ask - is it possible to add new "buttons" or sth to LED RGBW Swtich that is used by H801 Tasmota python plugin?
I need a buttons to set: FADE or run predefined behaviour (smoothly change colors etc..)
It will be also nice to insert input button to set the transition SPEED.

Is there any chance to achieve this by modyfing this python plugin? https://github.com/stas-demydiuk/domoti ... ota-plugin
