I am getting 'Invalid API key'
I double checked the key from the 'Inputs' device and also tried creating a new one.
tried different servers.
data.openevse.com/emoncms gives me 'Invalid API key'
emoncms.org/ gives me 'Invalid API key'
emonpi/emoncms gives me 'Failed to connect'
additional note, on OpenEVSE, services, I put the key in the Emoncms write-apikey field and click save, if I refresh the page and then click show password it is always blank, don't know if that is part of the issue.
I tried both the account APIkey and the input device APIkey.
Don't know why but this time the read/write API from the account worked, the device API does not..
Did you get this to work with a local server (emonpi/emoncms) at all?
I got it working on online version, but I did have a Rpi zero setup at one time just to test it, I forget the outcome, might still have the SD card with it setup.
