In home assistant, there is an option to controll tilt of the rollershutter but currently mysensors integration is not supporting that feature.
I decided to modify the integration and add such support. Unfortunately I've used V_VAR1 to carry position of the tilt, because it was only one I could legaly use.
It is working fine and I would create pull request to github, but I need common understanding with you guys which type of the message should be used. Is V_VAR1 ok or new one should be introduced in mysensors?''
