I have managed to rebuild my openHAB with openHABian and OH3 all via the main UI. A big thank you to all who contribute to this wonderful project! Even though I have been around from a 1.x environment I still think of myself as a beginner and have found OH3 to be much easier to get going.
I only have one challenge, self inflicted no doubt, I have this warning popping up frequently in the log viewer, 2021-01-04 15:19:37.373 [WARN ] [e.internal.SseItemStatesEventBuilder] - Attempting to send a state update of an item which doesn't exist: undefined
I don’t know how to track down the item which doesn’t exist, I have around 200 items. Is there a way to identify what item it might be referring to so I can resolve?
Hello Dirk,
do you also use rules? I have a rule with a switch / case scenario. I didn’t find information whether this scenario is also available in the OH3.
Do I have to set up the model also? As far as I know it the models haven’t been there in OH2.
Hi @Georg1975 ,
I also use rules. Nearly all my rules worked in OH3 without touching them. Only a few needed to be slightly tweaked so that oh3 will understand them.
Afaik all rules from oh2 are compatible to oh3.
You don’t need to use the semantic model for the enocean binding, it will work without it. But it is nice to have for the dashboard so I updated all my items.
You only need to make sure that you don’t use deprecated code eg tags for HomeKit. These won’t be recognized in oh3 anymore.
There are some breaking changes in the release notes that you should read beforehand. Notably for rules, triggeringItem is now only applicable for Member of group triggers.
