How the smartthing’s hub detects a custom device handler? What is the technology behind it?
I don’t believe the Hub does which is why all custom dth run in the cloud. I would guess the device commands and responses go up to the cloud and then back down to the hub as needed.
Is it done using fingerprint for a device in the Device Handler metadata block as part of the definition?
Thanks in advance
The initial discovery/pairing uses that…afterward I wouldn’t think it needs to since its already assigned a device type.
