Demo House: warning | MapTransformationService

I see the following error when increasing / decreasing the temperatures for room thermostats…
2016-06-02 18:21:22.571 [WARN ] [t.i.s.MapTransformationService] - Could not find a mapping for ‘-’ in the file ‘’.

My idea is to have clean running demo before I start using openHAB for my automation.

It’s a warning, not an error …
Edit your and add a line like:
and the warning will dissappear (the dash means the same as undefined).

Huh, you again… hi sihui, thanks for your reply…

A little anecdote: I used to work in a large commercial enterprise, hundreds of servers… nothing got onto them unless it would not produce ‘red events’ (errors). At one point we swapped a the backup software on all servers when the vendor wasn’t coming to the party fixing it.
With this mind set in mind mind, like it was said somewhere else: like buying a new car and the “check engine” light comes on, I am wary, as – no matter whether commercial or open source – you want people to use your stuff, yet, not even the demo works flawlessly… a big negative for me.

In any case: I made the mapping in and the warning is gone. :slight_smile:

What part doesn’t work?

A lot of people switch to openHAB because they are not satisfied with the other open source or closed source software available.
After a while you will see that openHAB is the most configurable and customizable home automation software available :grinning:

Okay, disregard, found your post about the weather binding …

The demo has at least three problems:

  1. the unknown - in (fixed)
  2. the Yahoo weather service
  3. 2016-06-04 09:50:03.599 [ERROR] [.o.m.r.i.engine.ExecuteRuleJob] - Error during the execution of rule Set random room temperatures
    java.lang.IllegalStateException: Could not invoke method: org.openhab.model.script.actions.BusEvent.postUpdate(org.openhab.core.items.Item,org.openhab.core.types.State) on instance: null

I understand that all hands are on deck for v2, but I think, someone who understands this thing should remove Yahoo weather and pick something else or leave it out, and fix error 3.

It simply leaves a bad taste for any newbie when like someone else nicely described: you buy a new car and the ‘check engine’ light comes on. :slight_smile:
