I just came across this article: http://www.itworld.com/article/2919325/personal-technology/website-monitoring-with-a-raspberry-pi-for-nighttime-alerts.html?phint=newt%3Ditworld_linux&phint=idg_eid%3Db4ed050ca62ad3f6d5c69e8448d945d7#tk.ITWNLE_nlt_linux_2015-05-19
I wish I had thought of it first! I’m in a similar situation – I constantly get emails and TXT messages overnight so I have to put my phone in airplane mode. A visual alerting might just help give me an early warning for come critical failures.
The Pibrella module that lights up and buzzes has its own web site, pibrella.com.
If I do anything with it I’ll be sure to post it here.
