Altering the network group advise

Hi I want to create a network group other than 210 as I may have two emonpi near each other in two different buildings, I see how to do this on the emonpi in the .CMS file, but is there an easy guide to configuring the emonth’s I am getting a bit lost.

Thanks
DD

It’s a menu option in setup & configuration, which you can access by having a programmer connected at startup.

However, be advised that the two groups still share the same radio frequency, so it’s still possible for transmitters in one to jam those in the other. Splitting the installation into two groups only means you won’t see the messages of one group in the other.
