I managed to the the Xively C client running on the TI CC3200 Launch-XL module.

This is going to be the perfect platform for the new boiler monitor using Xively.

I will be able to publish temperatures and even (if I want to) subscribe to channels so I could control the boiler remotely.

Also, Jeff gave me a board with five Opto-22 input modules, so I'll get those hooked up to monitor the three "call-for'heat" signals and the gas-valve-open signals so I can publish those along with the temperature data.

I'll need to look into the analog inputs on the CC3200 or build an A/D and connect it Nothing too difficult.

This is very exciting.
