How can I get a text message when my solar power system goes down?

Solar Power System

Episode 1660

Scott from Laguna Hills, California

Scott has solar power and occasionally, the system will pop a breaker and go off. But he won't get notified that it's happened, even though he has an IP based system. How can he set up a text message that can notify him when it happens?  Leo says if it was public, you could use a service like If This, Then That, to send you a text. But since it's private, then you may have to create your system using an old computer or raspberry pi to run a process that would ping your system to see if it's up and running. 

How can I test my Linux network speed?

Jeff from Idaho Falls, ID

Jeff is having speed issues on the internet with his Linux machine. How can he check for speed? Leo says that Linux has built in utilities just for this purpose. How about something that's cross platform with Windows? Leo says that is a different issue. He can run SpeedTest.net but that will only give him the speed of his internet connection, not his computer.
