Troubleshooting MonitorPro issues

Having trouble logging temperatures with Monitor Pro? 

Below are a few things that may need your attention:

Q: I am not getting any temperature readings.

  1. Check your hub is connected to your Internet Router. Do you have 2 ‘Red’ lights on?

2. Your network may have a firewall. In this case, you need to get your network administrator to allow outbound access through your firewall on port 3000

3. Your Wireless Hub may be too far away from your sensors or the signal is being obstructed. In this case, move your Wireless hub closer to your sensors. This may require a longer LAN cable.

4. Individual sensors can be checked by removing them from the fridge and placing them near to the wireless hub. You should see them reappear on your graph within an hour. If the sensor does not reappear, please contact

5. If you have multiple sensors which have all disappeared from your graph, the problem is more likely to be related to the hub rather than the individual sensors. Please check that it is still plugged in, with both red lights showing. If this is true, please reboot the hub by disconnecting the power and then reconnecting it. If your sensors do not reappear after an hour,  If your sensors do not reappear after an hour, please contact

Q:  I am getting intermittent temperature readings
1. The sensor signal may be obstructed by items in the fridge or freezer. Try moving the sensor closer to the door or your Wireless hub closer to your sensors.
