Possible to run 4 instances of CumulusMX on same PC?

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Possible to run 4 instances of CumulusMX on same PC?

Post by oh6hfx »

Hi!

I have been happy user of Cumulus for over 10 years, and at the moment I am maintaining web pages for 4 different weather stations.
These all Cumulus instances are running now simultaneously on a single pc and there is no problems.

Should it be possible to do the same with CumulusMX?

Yes. You just need to start each instance on a different TCP port.

And make sure the "Stop Second Instance" switch is off?
