Four Speed Fans, 25%-50%-75%-100%

[Taylorp913]

The treatlife fan switch connected to Home assistant through the TUYA integration has four speeds, 25%-50%-75%-100%.

Create and optional parameter between mid and high that can control the fan at 75%.

Something like this? speeds: low: 67 medium: 69 med-high: 73 high: 76

Would you like me to make a pull request for this?

Hi, after a year of a break, I'm back. Are you still using this automation? should I fix it ?

[Taylorp913]

Haha yeah I will be using it as soon as tuya fixes their home assistant integration to re-enable the fan control. Ultimately I love this automation and brag about it all the time.

i'm on it ... i'll send you a private version since I do not have any way to test it, once you confirm, will update the repo ...

Hello,

I had the insight but I wasn't found the word for 75 percentage !

The good word is halfway !

(you can try with your word you will fall on a mistake),

by my side I have found the loop in 3.10 on google but it print nothing...

and the indent show is false :

[(https://docs.python.org/fr/3/reference/compound_stmts.html#the-match-statement)]

a teacher of python was say it isn't advice to use python 3.10 now...

the code is over :
