@Benny5 On reflection, the chime on the Hub fails to register when the Bell is pressed. So perhaps I've got a coms. problem between the Hub and the Bell.

@Sealby73 Thanks for your help. While my Hub accepted and formatted the SD card it still shows the SD storage option on the D235 as 'No microSD card' under Local Storage.

@Sealby73 Which menu option allows the setting of the Hub as the SD default storage option. I’m struggling.

@Benny5 Got there in the end. Deleted/Added everything, restarted router and it appears to have resolved it.

Trying to setup a new Tapo D235 doorbell and Hub, however, I can’t get beyond the point of connecting the D235 to my Eero 6 router. I’ve disabled the 5GHz option to allow access to the 2.4 option...
