The plugin works great. I have not found any errors so far.
What bothers me a little, that the notifications always come back when a streamer is live. And if you set the announcementIntervall high, that the notification comes only when the announcementIntervall has run. This is at least my feeling.
I would suggest for me that the notification is sent once when the streamer goes live.
I just released a new version that solves this problem.
unmodifiedInterval is old announcementInterval, it shows all online streamers to all plyaers.
updateInterval is a new configuration to call TwitchAPI at a much higher frequency, this option, if no streamers start a new live, do not perform any announcement
The combination with thesse settings solve your needs
