Since I am unable to post in the original thread, I am setting up a new thread.
To get a Shelly plug s to communicate with Loxone I did this:
In the I/O actions of the plug enable the Output On URL
Then Write
http://user:password@LoxoneMiniserverIP:Port/dev/sps/io/Shelly_Plug/on
Shelly_Plug is the name of the virtual input. I have set this input type to switch. So now when I use Alexa Loxone will also update.
Then for the Output Off URL just change the on to off
I will be updating the tutorial I did, but this won't happen until the new year.
