btw, i have an ip camera in the garage and monitor humidity and temperature off my digital thermometer/hygrometer. it has night vision so i can see it any time. this helps calculate simulated tire psi, and also to prevent dew build up on my cars and tool cases on days when temp & humidity is significantly higher outside than inside the garage.
at sub 50F, cant run dehumidifier effectively (machine would freeze) so best not to open the garage door on those days, or run a fan and quickly close the garage door on trash days, etc. this also comes from experience over the years.
ive already posted about these things on this site though...
