I thinking about implementing a new action to add (yet) another messaging app/service. I’m wondering if there is any guideline how to implement pure openHAB 2.0 actions. If I look at the addons repository of openHAB 2 I don’t find any action. All actions are implemented for openHAB 1. I already read that V1.x actions may be compatible but as I’m using V2.x I would prefer to implement against that platform rather than V1.x.
Is there any major difference between V1 and V2 actions?
