External Temperature Sensor stopped working

Purchased the base module and some external sensors a couple of months ago and configured it at my desk before deployment. Had everything working. Moved to their final location and the external temperature sensor is not being seen now. It is getting power (light is lit), but the OLED display doesn't show it, nor does the web interface. The base is a V5 model. I have run through a factory reset on the base module to no avail. Thoughts?

I have connected it to another port on the base unit, as well as attempt to connect it through the sensorhub to no avail. I only have the one sensorgateway base unit at this point though.

Jstasik, seems like your sensors is defective. If the sensor was not subject to accidental damage such as drops etc... then you can initiate a warranty repair from your order page or from your my.serverscheck.com account

Thank you. I attempted to create a my.serverscheck.com account (bought through a reseller) and when I click on the validate email link I am presented with the following. Can you assist with this, or is there another channel?

Please try again. You can also initiate a RMA through the reseller you purchased it from; they can do it from their order page.
