Anyone Using Remote Comms For Alerts?

Has anyone here hacked out a way to get gSender to send out messages to let the operator know it’s time to change a bit or that the job has finished. I’m usually in the shop while carving but I’d be lying if I told you I never walked out while chips are flying. I was thinking of using NodeRED to manage the alerts. Any ideas?

Being on OSX, an optional system call to a shell script of my making would be nice
