what os are you using at that location? anyway you can try to launch cgminer via ssh and monitor the temperature with the commands available for it in cgminer
this can help you, same issue basically
https://litecointalk.org/index.php?topic=4624.0I have a linux server(console only) on my remote end that I connect to and then from there ssh into the antminers. On my C1's, I can use "screen -r" and it will display cgminer's interface. The S3's don't start cgminer the same way so that is not an option in this case.
I am trying to get away from having to port forwarding http access to each miner on my router. That will drastically hurt my security.
