A bump for this feature, I am currently using the above JSON URLs along with some deducing from the IDs of each field in the web interface source code to update the RDS text directly from the playout system wich is working well.
Would love some info on how to get a stream/feed/update of the processing updates (in/out levels at least) etc to display on some hardware like VU meters and HMI screens on the rack and also use for silence detect and triggering OSC and MIDI messages to the studio switching mixer we are using/failover etc.
