Binding not updating channel

Add-ons Bindings

I’m trying to write an OH2 binding with Eclipse Smart Home but ran into the problem that my channels are not updated after calling

updateState(new ChannelUID(getThing().getUID(), CHANNEL_TEMPERATURE), new DecimalType(new BigDecimal(temperature++)));

I “think” I copied the yahooweatherbinding (YWB) code to create a simple channel with fake temperature data. Perhaps I made a mistake copying, but I cannot find it.

I did notice however differences in the log:

  1. For YWB, handleCommand is called with command RefreshType during the startup phase. For my code, handleCommand is never called.
  2. For YWB, there are ItemStateEvent and ItemStateChangedEvent in the log as a result of updateState; for my code these do not appear when I call updateState.

The channel declarations in thing_types.xml are the same. And at least I can read parameters specified in demo.things.

Am I missing something “obvious” that produces this result? Other suggestions how I could get a simple YWB like binding to work (e.g. periodically update a number) as a starting point?

Many thanks!

I got this working by starting with a copy of the yahoo weather binding and then changing gradually. Not sure what was wrong with my first attempt.
