Changing scale x3 for a 200A CT input

Yes, that will have been the local emoncms where you edited the local emonhub settings that would have applied to your emonTx had it been sending it’s info via rfm to this emonPi. But because you are sending the data direct to emoncms.org using an emonESP there is no emonHub enroute, so you must do those adjustments in the emoncms input processing. There is no emonhub config page on emoncms.org, because emonHub is a locally install software.
