Monitor the status of your Herpstat product online
Receive Scheduled Emails or TEXT Messages with status information
Receive Emergency Email and TEXT alerts
Update the Herpstat's firmware when code changes have been made

Yea straight from spyder it is $395 shipped. For the price of that vs. buying 4 proportionals, you can't beat it. Plus you have the software and I would like the text alerts if temps drop too much. About the online status, does that mean I would be able to log onto something and see real time temos? It will really help since these 2 racks are the only ones I plan on using for now.
