Thanks for this ‘manual’. But unfortunately it will not work. When I put the http link in a browser I get the message: {“code”:401,“error”:“not\_logged\_in”,“error\_description”:“You need to log in to access this resource”}  
On this community site I found the error message in this post: [HTTP GET commandos naar Homey versturen](https://community.homey.app/t/http-get-commandos-naar-homey-versturen/8920/2)  
There they say you have to use https protocol, but HomeWizard does not accept that.  
What do I wrong?
