Monitoring a wood stove flue temp and capturing the data

[ISY4Me]

Those that heat or augment their heating with wood stoves are always concerned with control.  I use surface temperature probes to monitor the blower air temp, but you have to be watching them.  I also use a flue insert probe to monitor the temperature of the gases coming out of the firebox, but again it is a physical readout and you have to physically monitor the performance. 
 

Since my stove is in the basement, it concerns me that if an over temp situation is brewing that I could miss it. 
 

What I want to do is to use a k-type probe designed for inserting into the flue pipe and capture the temperature reading so my EISY can notify me to address the situation.  
 

Insulated k-type thermocouples are widely available and there are lots of discussions about using an Arduino to gather data, but I have not seen discussions about capturing the data and sending it with a REST command to the EISY.   I do something similar with the DS18B20 and a WebController CAI 8bit board for monitoring room temperatures and I was looking to see if there was a way to do something similar with a k-type thermocouple  

Any thoughts?

I have a wood stove. I added a furnace air return on one wall above it, with an older Venstar thermostat (T6800) that activates a blower in the air return to draw more air into it when the temperature exceeds a threshold. It's an external thermistor mounted just behind the return grille. This particular thermostat isn't compatible with the eisy Venstar plugin, but a newer one could be used (I also have two T7900's working with the plugin). An alternative thermostat would be an Insteon 2441TH, often available used for very cheap. The temperature sensing thermistor in those is very easily accessed and removed for mounting externally. I actually have two of these that I'll be using for a solar pool heating project, to have the eisy turn the diverter valve based on the water temperature vs the air temperature in the rooftop panel boxes. I've been doing this for years with my Ocelot automation controller but this will now be an improved version on the eisy.  

For the wood stove, you'd be monitoring the air temperature close to it, the thermostat's temperature range isn't high enough to directly monitor surface temperatures, but you could establish a correlation of the air temperatures vs surface temperatures first, and go with that.
