we installed our first LoRaWan Gateway with the RAK2245 Pi HAT (Firmware: EAK2245&RAK831_based_on_Raspbian_OS_V2.9R_20190627) and an Raspberry PI 3B last week on our desk. We have only one node, a temperature sensor how sends every 15 minutes one telegram. After a while, approximately two or three day the gateway was unreacheable (SSH and Webinterface) anymore. A Ping was possible. A reboot didn’t fix the problem. We used the internal lora-server. The device was installed in a electrical cabinet where the door was open - because of the heat of the module.
First problem: the system crashed after a while and is unreachable any more.
Sencond problem: The system is too hot for the installation in an outdoor elextrical cabinet.
What can we do? We should install the system on Saturday at a customer.
