**Describe your problem**
Hey,
I have a Shelly 2.5 installed which works as a roller shutter. Because there is only one switch in my house that controls two rollers, Shelly isn't able to do the calibration. I always get an error.

That's why I only wanted to be able to use the open and close features of the roller. I don't need them to be opened to 30 % or so. 

Unfortunately the plugin gives me an error, if the roller isn't calibrated.

When I use another plugin an import the shelly like a garage door which is opened and closed via URL-link, it works – but I want to use it as a window blind and not a garage door due to several reasons.

Can you help? Can I configure the shelly in you plugin manually? Or can you provide this feature in an upcoming release?

That would be so helpful.

Thank you very much!

Yours
Benny
