HABApp: Events vs. job control

1

Many of my rules are executed regularly @ 1 minute. So i created a number item “Time”, which has the current time (hhmm) and is changed every minute by job control (timer).
The rules depending on time can now register the “on change event” of this “Time” item. This works. However, I some times get warnings like this:

The other implementation i could imagine is, that every time depending rule gets its own 1 minute job control. Of some rules, i create multiple instances (up to a dozen). So I guess, this would need more resources.

What is the preferred way?

Use the scheduler in every rule instance, e.g.

class MyRule(Rule):
    def __init__(self):
        super().__init__()
        self.run.at(self.run.trigger.interval(None, 60), self.my_func)
    def my_func(self):
        ....

It’s all pretty lightweight, it doesn’t really matter. The scheduling happens in the event loop which is quite optimized.
