| Re: [mosquitto-dev] map IP to topic |
or.... as it sounds like your own application if you have them calling you for support, just make it part of your .... own application! Publish the client ip in some status topic you use for this purpose. Use pub/sub for what it's for. Trying to hack brokers to get things back out of them is just perverse and generally a waste of time. Ben Hardill <hardillb@xxxxxxxxx> wrote: > > 1.
