Sometimes buying it ready to go is just not any fun. If you've got the time, have fun building it.

I'm making an alarm as well.
I was just going to tape the temp probe to the flexshaft with black electrical tape.
The monitor I'm working on can be monitored from remote (it has a Web Server built in), and it will send text messages and E-Mails. It will also Pause the machine when the temperature rises above a certain level.
Now I just have to finish the darn thing. Been working on it too long!

I didn't conduct an extensive search, but here is an inexpensive one: http://www.coleparmer.com/Product/Di...Np3xoCxRHw_wcB I used one like it years ago that had an output to switch a device on or off - used it to charger NiCad batteries and shut off the charger when the battery pack warmed up. Sorry, don't recall where I got it.
I think the Raspberry Pi might be a bit of an overkill?
Arduino with a Lantronix XPort.
Yes, I was going to wire the Cover Switch through a relay.

Doesnt the cost two of those devices (Ardunio & XPort) far exceed the Rasp Pi? I started out doing everything with Arduino's until I fell in love with the Pi. Ethernet, webserver, mysql server, a ton of packages rightout of the box seems to make the PI a hands down favorite for Internet of Things (IoT) in my opinion. Only real downside is none of the gpio are buffered on the Pi. The raspberry pi and the pi face board are starting block for most of the IoT's i've made recently.

I have had 3 A machines before I got my B then added a C. I have NEVER had a heating problem with my flex shafts after the 3rd lubing with Lubraplate 930AA. It takes 3 times for it to really penetrate. Of coarse I do re-lube every few months. They run barely warm. I did replace the spacer spring on the B a while back.

My LCD displays arrived and while I was looking at how to wire them in I found this project ready to copy - displays temp and humidity with a sensor I have around the MSL somewhere. This part will be for measuring ambient temperatures and humidity.

Wiring in a temp-only sensor or two should be easy peasy.
