[schedy] expression for switch actor didn't parse

[insajd]

Hi, While writing this, got my issue solved. But here's what got me confused: Here is my config which was failing.

  actor_type: switch
  schedule_prepend:
  - x: "on" if state("sun.sun", elevation) <= 0 else Skip()
  - v: "off"

This is error log which I was receiving

2018-12-18 22:13:39.067703 WARNING AppDaemon: parser says
2018-12-18 22:13:39.067971 WARNING AppDaemon:   in "<unicode string>", line 30, column 13:

2018-12-18 22:13:39.068046 WARNING AppDaemon: expected <block end>, but found '<scalar>' while parsing a block mapping

These variants fail as well:

• x: "on" if state("sun.sun") == "below_horizon" else Skip()
• x: on if state("sun.sun") == "below_horizon" else Skip()

Approach which worked (found on Generic Actor documentation page):

• x: ("on") if state("sun.sun") == "below_horizon" else Skip()

Hmm, have to investigate this further. The expression you tried should actually be accepted.

Ok, having a string at the beginning of the expression is considered as invalid YAML by the parser. I'll change all examples to quote the whole expression, because what you used as a workaround is in fact working, but might be difficult to understand why for people not familiar with Python.
