What you need to get started
A gateway, the traps and the app. The gateway connects via cellular, and the SIM card is included in the Starter Set. A LoRa field tester is also included: use it to check whether the signal reaches the planned spot before the devices are installed, instead of finding out afterwards.
Where a second gateway makes sense
The range depends on the building: reinforced concrete, cold stores and deep basement corridors cost meters. The rule of thumb from practice is not the floor area but the line of sight: the more solid walls between trap and gateway, the more likely a second device is worthwhile. The field tester answers that in ten minutes.
