Call-service error. 'Dimmer' object has no attribute 'set_values'

[torbjorn-stabo]

Hi.
I'm trying to set the brightness of a Shelly dimmer 2. I assumed the way to do that would be using a Call service node(besides, it lists set_value as a service and the documentation at the bottom of the Edit call service node tab explicitly mentions brightness..).

However, when I do that I get "Call-service error. 'Dimmer' object has no attribute 'set_values'" in the Node-red debug tab. (Yes, set_value with an s there, but not in the available services listing I mentioned earlier)

As you've probably guessed long ago by now, I'd wish for that service call to just..work. I guess the solution would be to add a method set_value(s) to that Dimmer object?
