Two nearby emonPi (handle different set of sensors)


How can I configure in emonHub for each emonPi to handle it’s own sets of sensors (e.g. emonTH)? i.e. can I don’t see other sensors that not belong to a particular emonPi?

Thanks in advance.

The correct way to do this is to use a different RF “group” for the second emonPi, currently it will be set to 210 in the [[RFM2Pi]] [[[runtimesettings]]] section of emonhub.conf. You can use any number from 1 to 255 (except 210) for the 2nd group, each device reporting to that new group will also need to have the group setting changed, that will involve uploading an edited firmware sketch to each device.

But to add, even though there are two groups, both share the same radio channel, so there may still be occasions when messages collide in the air and corrupt each other.
