Setting up cold room sensors are a bit different from our other sensors. In this article we will explain how to do it.
The device is shipped with the batteries installed and in a state of DEEP-SLEEP until activated with a magnet. There is no need to open the enclosure to activate the device.
- Step 1: Make sure the gateway is turned on and connected to the network.
- Step 2: Place the magnet within 2 cm of the "Magnet Switch" on the side of the device for more than 3 seconds but less than 10 seconds. The exact location of the "Magnet Switch" is shown as the "Reed Switch" in the diagram below (it will be an embossed image of a horseshoe-shaped magnet). You'll know you got it when the "Network Join" light blinks.
NOTE: We have found the magnet that comes with the device to not be strong enough for activation. You may need to find a rare-earth magnet to use (usually a strong refrigerator magnet will do). 
- Step 3: Remove magnet from device. the LED will blink until device has joined the gateway network.
