Hi,
Any tip/advice for a newbie on how to debug event transforms? Would it be possible to output messages to any of the log files?
Thank you,
Hector

One of the context variables passed to transforms is 'log', which is a standard Python logging logger. You can use this to log information which will show up in the zeneventd.log file (zeneventd is the daemon which executes event transforms).

For example, in your transform you could write:

log.info('Device is: %s', dev)
