Thanks for the answer!
No I’m not trying to flash Tasmota.
Im trying to use the SmartThings-Devide-SDK and flash the sample Script for a basic SmartThings-Switch, to control an ESP8266.
If I flash the binary I get by building the switch-example-script and start SmartThings on my phone, I receive a notification that a new device was found. However, if I click “Add device” in the dialog, the App starts to connect and fails after a few seconds with the message “The selected device is not supported.”
I did every step provided by the SmartThings-Documentation for a direct-connected-device.
My goal is, to switch on a relay which is controlled by the ESP using a Bixby-Command without having a SmartHub. This is why I need a direct-connected-device.
I hope this helps to understand, what I’m trying to do.
