Other info:

If i set the speed value in Tuya app, it show correctly in HA. Only the "writing" side is not working.

If i see it correctly, in today release this commit is approved, right?

#542

[fbloemhof]

There is a bug in the code, the speed is sent as an string but should be an integer.

When changing str to int on this line, setting of the speed works.

I'm nog sure how contributing to this project work but if I can find out I will do this.

FYI, This PR fixes this: #942

[vampywiz17]

@deese

It fixed! I hope add it to next release.

[fbloemhof]

How can we get this in a future release? My workaround was gone with the last update.
