And this is what “Check it out” returns:

Note that this is the ONLY ESP32 device I have in ESPHome. Any guess what’s happening?

I’ve had this happen every now and then (with absolutely no apparent reason). What I’ve ended up doing is deleting the device from the ESPHome INTEGRATION (not the add-on) and then re-added it when it was re-discovered (might have required a HA restart, can’t remember).
