I have been wondering whether there is a preferred rules engine for OH3? To my understanding upcoming milestones will be providing more migrated stuff i.e. jython and more. What about Node-RED and how current it is as a rule engine even for OH3? I am aware of @Dome post on this topic from OCT '20 and his statement on node-red-contrib-openhab-v2 as OH3 fit.
I haven’t had time to follow the advice of others on the nodeRED OH3 thread, but it sounds like it’s been stable, as long as you:
Use the plugin with green nodes
Set up the access token
Don’t use both openHAB plugins simultaneously
As far as stability prior to 3 - I’ve run about 80% of my rules in nodeRED for several years. It’s just as stable as openHAB in my opinion. I’m going to try to teach myself some of the new programming options once they’re out, but my next task is moving my old nodeRED flows over to use my 3.0 install.
Anything else like Node Red, HABApp, etc. is external to openHAB so how current it is or is not is going to depend on which specific one you are talking about.
Anything outside of openHAB has it’s own roadmap and plans independent of openHAB.
The only reason I replied is because a lot of users have difficulty in understanding where the boundaries of openHAB are.
Thanks for your reply.
Also still struggling a bit with all the languages.
I know how to program e.g. PLC’s but not in code language like python or java script. My idea with OH3 was to move away from Node Red and learn to code this time, but with all the options in languages I decided to let things for the moment and wait a bit which language will be most common and learn that one.
If popularity is going to be your measure, Rules DSL is by far the most popular and will likely continue to be so for a long time.
