We can also add the "sufficient SOC/range reached" notifications, the low SOC alert and the low 12V alert to the framework.

Porting the low 12V detection is on my list for today/tomorrow. For the sufficient SOC/range notifications, I currently still (mis-)use the topoff state, which
is irritating to users.

Notification config should include a channel selection for each, so users can choose which of them to get by SMS. May be combinable, i.e. instead of a bool, use
a set of ("ip", "sms")?
