Ok,
to bring this one to an end here is my final experience: Part# 6372 arrived, installation/recognition no problem at all both with Console and WeatherCat.
And here is for what I use this additional temp sensor: I was always curious about the inside temperature of my self-made webcam-housing. During the summer months I think it is very hot in there, and during winter with outside temps lower than -15?C I think the housing is far below zero, too! So this Canon Powershot G10 did a good job during the past few years (and hopefully it does some more years
).
Cheers,
Reinhard
