Hoi

Can some one help me, I like to build some functions on my node-red implementation. to control them via an API. Very simple when sending a PUT I want to control the GPIO  
and a GET which show some results back

PUT "[https://HostRP4/ASCOMInitiative/api/v1/dome/0/closeshutter](https://HostRP4/ASCOMInitiative/api/v1/dome/0/closeshutter)"  
PUT "[https://HostRP4/ASCOMInitiative/api/v1/dome/0/openshutter](https://HostRP4/ASCOMInitiative/api/v1/dome/0/openshutter)"  
which cause a status change on the GPIO pin

GET "[https://HostRP4/ASCOMInitiative/api/v1/dome/0/shutterstatus](https://HostRP4/ASCOMInitiative/api/v1/dome/0/shutterstatus) gives the status predefined status back like open, opening, close, closing

Can some help me to get this done

This all is related to ascom-alpaca. I like to control my Roll-off Roof also via API

Thank in advanced

Chris
