Hi, I’ve finally managed to set up my Wemos D1 Mini Pro with an OLED display. I’ve configured everything, and it’s working as expected, displaying the information I wanted on the OLED screen. I can see RSSI and the IP address on the display.
However, I can’t see these values as entities in Home Assistant. When I open the ESPHome add-on panel, I can see the RSSI value there, but it doesn’t appear as an entity – it just says “entity unavailable.”
I’ve already tried removing the device twice and even deleted the ESPHome integration, but nothing seems to work. I can’t process this further in Home Assistant.
Additionally, I noticed that when adding my ESP device, the integration doesn’t ask me for the API key as shown in the instructions. It just adds the device without prompting for anything.
Does anyone know what might be causing this issue?
