Hi...i am a new user here. I built a RFM69 gateway and a node.I decided to place the RFM69 node in a basement storage room. The room has been flooded a few times historically, so being able to monitor humidity in the room seems like a good idea.The room has thick brick walls, which the RFM69-433MHz radio is much more capable to handle than the nrf24. Still, I wanted to keep an eye on the signal strength. Because of this, I added code to the gateway to report RSSI from the node.
