[vz-users] Reconfigure vzlogger NOT to push meter readings to middleware?

[Andreas Goetz]

PPS: I've pushed an UNTESTED change here:

https://github.com/andig/vzlogger/tree/nullapi

If you add protocol=null to a meter it should not look for a middleware.
Feel free to raise issues at my repo.

Freundliche Grüße/ Kind regards
Andreas Götz
