Boxcar Notification - rule to notify, can a rule execute a rule?

I have a rule that at the moment executes a boxcar notification.

I’d like that to be generic so that I can call it from other rules, ie when batteries get low execute my boxcar rule with some parameters saying item “xyz” has condiction “abc”

Is this possible?

See:

I think I ended up using a rule to execute a script. As it was easier to define all the curl parameters in a script than in an OpenHab rule.
