This is the Logger…
The Logger sits in your fridge.Â
It uses Bluetooth to communicate
The Logger broadcasts the temperatures using Bluetooth. Just like your mobile phone connects wirelessly to speakers or earphones.
Bluetooth can go up to about 50 meters
That is half the size of a football field.
This is the gateway…
It receives the temperature readings from the Logger.
It connects to your network.
Either with WiFi or Ethernet. Click below for more information.Â
The Gateway and Logger need to be within Bluetooth range.
Place the Gateway in the same room as the Logger for optimum connection.
The Gateway and Logger will not connect outside Bluetooth range.
If the logger is too far away, you will either need to move the gateway closer, or add an additional gateway to your network.
Remember that the gateways support WiFi and this can make it easier to get closer.
Surfaces can stop or weaken wireless signals.
Brick, plaster, cement, metal, stone, and double-glazed glass may create issues with signal strength.
Avoid having your logger and gateway surrounded by them.
Wireless signals can bounce off certain surfaces.
Certain materials will reflect wireless signals.
Relying on signals bouncing is not guaranteed.
A gateway in one position may not receive a signal, but when angled in a different way, can respond clearly, like a telephone call.
Standing in one place could cause a bad signal, but moving a couple of steps away, can significantly improve the call.
Water will drown wireless signals.
Wireless signals wont go through water, this is important with condensation over the logger.
They obviously won’t work underwater. They are also not water proof!
Rain will also shorten the range.
Ice will “freeze” wireless signals.
Wireless signals wont go through snow and ice. This is a problem in freezers where icing over and condensation can occur.
How to improve the signal
- Remove obstructions surrounding the Logger: if possible, remove anything around the Logger. Make sure to move the Logger AWAY from metal objects
- Reposition the Logger: Try moving the Logger closer to the front of the fridge or towards the seal. Make sure the Logger is AWAY from any metal surfaces
- Avoid any obstacles that may be in the way such as walls, shelving or furniture that may interfere with the signal. Obstacles can be avoided by moving them or positioning your Gateway to a higher position.
- Remove obstructions surrounding the Gateway: Don’t place the Gateway behind or in a metal object (computers, server boxes or cupboards)
- Reposition the Gateway: Try moving the Gateway closer to where your Logger. This is possible by connecting the Gateway to WIFI or using a longer network cable.
