I have a small server room with about two racks. A 25U & 45U rack. I have some older APC UPS. One of them is a SMARTUPS.
I desperately need a device to monitor temperature. I was hoping to use something as simple as a USB device that reads air temp. But all I find are these Environmental Monitoring systems from APC which have all the bells and whistles.
I am simply trying to go for a solid inexpensive solution in order to receive temp alerts.
