% Timeclock example for using alarms
% Publish time values (format hh:mm:ss) on the "/timeclock/on_time" and "/timeclock/off_time" topics
% to the brocker and the build-in LED will switch at the given times.

% Config params, overwrite any previous settings from the commandline
config ntp_server	1.pool.ntp.org
config ntp_timezone	1

% Now the initialization, this is done once after booting
on init

	setvar $command_prefix = "/timeclock"
	% Command topic
	setvar $command_topic = $command_prefix | "/#"

	% local subscriptions once in 'init'
	subscribe local $command_topic

% Now the events, checked whenever something happens

% Is there a remote command?
