Esp8266 wifi gateway with RSSI for RFM69 and Wifi

[mfalkvidd]

As part of helping troubleshooting in this thread, 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.

I also added support for reporting the gateway's own perceived signal strength from my 2.4GHz wifi router.

The result looks like this:
