Yes! My wood stove monitor’s data is now received by my Power Monitor and pushed to my channel on ThingSpeak.
The data is transmitted to another address on the same channel. I did it this way because nRF’s pipes work only for one receiver with multiple transmitter. On the Power Monitor side there is another DirtyPCB to handle the nRF24L01+. By using my “nRF platform” 99% of the code was already done! All I had to do is write some code the receive the formatted data on the second serial port available on the Power Monitor. Interconnecting them was a snap: Vcc, Gnd & Data!

"First of all, that “black on blue” is a crime against humanity (on the display) and should be fixed ASAP."
I want to apologize to all mankind for this horrible mistake. I should haved done better. Here is the display updated.
One small step for hacker, one giant leap for mankind.

From what I've found from my research, the probe or surface thermometer must be placed at least 18" (45.72 cm) above the top
of the stove. There is no indication on the maximum but I think it cannot be placed too far from the stove.
Data from SBI Heating Accessories for a probe thermometer:
- 100 - 400°F: Temperature too low. Fire may be dying out. Causes creosote accumulation, smoke or soot.
- 400 - 900°F: Operating efficiently.
- 900°F +: Possible overheating. These temperatures may be reached for a brief period during initial firing. Not recommended for prolonged periods.
Magnetic surface thermometer on a HEPA stove: make sure that the temperature does not exceed 475F (246C).
Source: Drolet Stove Builder International inc. I have no offical data for the minimum. I have seen between 270F and 475F somewhere.

Q: Why a PICF690 instead of XYZ?
A: I’m used to PICs. Why I picked this one? I don’t know. I should have picked my favorite one (PIC18F25K22) but I don’t know what I was thinking that day.
Q: Why PicBASIC?
A: I’ve learned C with TurboC 20 years ago. It’s been now 20 years I’m programming VBA and VB.NET. I’m just too lazy to go back, don’t have enough time to learn other languages and PicBASIC student version is free so…
