I did not upgrade OH. I did not perform an upgrade/update/apt-get install. Nothing. Nada. Was working. Reboot. Stopped working. No codebase changes.
The rule triggers for Time cron "0 30 07 ? * * *" (using the “old”(?) cron rule trigger) but the same “old” cron rule trigger with a cron expression that include more than just a time of day has stopped working.
I’m not a big fan of PaperUI and all of the excessive point and click. I installed the NGRE (Experimental). NGRE didn’t change my mind about PaperUI.
Disclaimer, I did not take the time to relearn rules using the NGRE. I created a new rule through the NGRE and started adding triggers (via the exact same cron expressions). This took a good 5-10 minutes to point and click through it all compared to rules via cut & paste and a few seconds editing the triggers/expressions. I got to the part where it asked me to reference a rule to run and that’s where I stopped. So now I have a rule trigger that calls another rule but I don’t know how to create the other rule and does it have to have its own trigger, etc… and all I wanted to do was to have an action to log some text… and doing that was not in the list of actions.
I admit that I am not a DSL fan. But I have invested a ton of hours to become dangerous with DSL… and to know how to clone code snippets to create new automations. I guess I can start over and learn JSR223. But I’m not going to switch to point and click. It’s just requires to much repetitive action and consume too much time for even simple actions.
That’s a big “once”.
Maybe it’s time to learn YAML
