RSSI showing different values

When I use ESPHome / device / logs to connect I get the following:

[14:30:11.787][C][wifi:838]:   BSSID: [redacted]
[14:30:11.787][C][wifi:838]:   Hostname: 'arena-water'
[14:30:11.787][C][wifi:838]:   Signal strength: -66 dB 

however the RSSI figure shown on Homeassistant dashboard for the device is -127dB

I have just switched the device to a different WAP, the configuration allows for 2 WAPs:

wifi:
  networks:
    - ssid: !secret wifi_ssid
      password: !secret wifi_password
    - ssid: !secret wifi2_ssid
      password: !secret wifi2_password

It is showing similar for 3 devices that I have just updated, the Lovelace RSSI is showing as -127dB for all 3
