Tweet of machines

I'll be very pleased if you could help me find out answer to the following project: I have a wifi internet, I have small bulbs that light up when my machines run and off when they no longer work. And I'm looking kind of very simple interface + software will allow me to send automatically periodic Tweet to a company followers private group to inform the state machine (running or stopped). Example: 3 machines running, 7 machines stopped. There is a little hardware and some software to develop, something very simple and I am sure this has already been developed and could be shared to help or not too expensive to buy. Thanks a lot for your kind help.
