So there seem to be three different flavors of RSSI:
Hub RSSI as reported in hub_status is the WiFi signal strength at the hub, that it uses to connect to the Internet.
Device RSSI as reported in device_status is the signal strength of the wireless link between the device and the hub.
But device_status also lists hub_rssi, which is neither of the above, and varies between 0 for my AIR and -94 for my SKY
Can anyone confirm the above, and tell me what the third RSSI is?
Also, what’s reasonable numbers for these? My Hub (WiFi) RSSI is -79 which appears to be good. My AIR is -57, which appears to be OK, and my SKY is -87, which would explain the dropouts (it’s on the other side of a metal roof).
