What is your cheapest option to monitor temperature in two adjacent server rooms?
Detailed Question:
What is your best (cheapest) option to monitor temperature (only) in two adjacent server rooms, sending email if either or both get too hot. An ethernet connection will be possible. We don't want to dedicate a PC to this full time, but a laptop can be.
HW Group STE is a good solution, as is the SensorProbe2, both are Ethernet devices and both can send emails to one or more addresses.
