Frequent WiFi disconnectioms, multiple WiFi log

Hi, I flashed a Sonoff POW, which always had problems connecting to WiFi, with ESPhome from Tasmota. I put in configuration 2 SSID (both are not optimal in that spot unfortunately)
The disconnection are a bit less then with Tasmota, but wish to know to which WiFi does the pow connect too during the day.
Is it possible to know it in frontend (like now is possible to know the signal strength during the day but not the SSID)?

You can add a wifi signal sensor to your .yaml:

  - platform: wifi_signal
    name: "Bathroom Wifi Sensor"
    update_interval: 180s

If you have the web server enabled you can check it there:

yes I have that, but I wish to know at which wifi SSID it refers

Is this what you want?
