unknown devices on WiFi

I have just downloaded the EE app and discovered that I have 13 devices that have used my WiFi and I’m quite shocked.

Most are ‘Unknown device’ but one is called 'expressif' and it’s been offline for 18 hours.

Does anyone know what 'expressif' is and how I can find out what the ‘Unknown devices’ may be?

Any help appreciated.

@AcornBob : By looking up the MAC Addys shown against them by the router in MAC Address Lookup to find their Vendors might give you some clues.

@AcornBob Count your connected devices, and each device should have a contained label on it with it's unique mac address on the label!
