Until I build/order some sensors for this, my sensors page sure is lonely.
I'm sure there are temperature sensors, either discrete ones on the board or integrated ones into some of the ICs accessible to the architecture. Why not present "Router Temperature" out as everyone's first sensor, the same way 'Tom' was everyone's first MySpace friend?
This would, I think, spark a lot more interest in the sensor page and sensors in general. Perhaps you could even set temperature alarms to notify you when your router (and, by extrapolation, perhaps your house) is too hot or too cold?
I suspect a simple firmware update would get every Almond+ owner a 'free sensor' and we'll all have a bit more fun with our routers.
