Just noticed this thread - I have a device that's in development currently, similar core functionality to the ThermaData device, but built specific for wood stoves with added functionality beyond what the TermaData does and easier to use. With it I have devleoped mobile apps for both iOS and Android. Currently in the process of getting it certified for safety (which is a hurdle for any electronic device, especially one that will be used near a wood stove!) in order for it to legally be sold. Once I have a prototype available I will be soliciting beta testers, here naturally. Stay tuned...
