I have different IMAP devices such as Debian laptop, iPad and Android -phone. When I get email, they all start banging. How can I put them to silent mode automatically when I put alarm clock on?
I don't know any fast way, perhaps you need to put every device one-by-one to silent mode?
But they are not optimal solutions, you waste time in putting things back.
Novel idea: suppose devices are connected to the same Wireless-network, can you somehow turn them to silent mode by this network using NAT and providing some one-time-password?
