Excellent. You’re almost there. Just to confirm, on your iPad if you go to the smartthings app.
Once loaded. Click on the middle icon at the bottom “Automation” then the rightmost tab “smartapp” then select “webcore” then register a browser.
This will give you your browser registration code.
Then navigate to the address shown. Once there you will input the code you have just been given.
Next is the password screen. This is the password you set up in the settings of webcore. If it’s not working for you and you are sure it is correct. Just try changing it in the settings.
