Set state without communicating with a device using configuration.yaml

[bbrendon]

For example change a switch state from on to off without activating the switch. This can be done from http://x.x.x.x:8123/dev-state but not from configuration.yaml.

There’s a discussion about it here.

Set state without communicating with device?

Looks as if the set_state function in the API only sets state internally in HA. Maybe I can use this from an AppDaemon instance to accomplish what I want.
