∙ Make sure you have connected the air conditioner to a wireless router.
∙ Try recovering your ID and password from the Samsung account page.
∙ This may fail temporarily due to the distance from the router or some
interferences. Try again later.
∙ You can add device units only in AP search state.
Check that both the power LED and Wi-Fi setup LED are turned on.
Otherwise, press and hold the AP button for over 5 seconds to activate the AP
search.
∙ You cannot add any device without deleting it once the device has
already been added to the SmartThings app. To add the connected
device again, first remove it and then proceed with the process.
∙ If you are using a Samsung smartphone, the server may not be connected
temporarily. Turn off and on the power of the Wi-Fi Kit, launch the
SmartThings app again, and then try adding a device again.
∙ If your phone is not a Samsung product, check that you have entered
a wrong Wi-Fi password. Try adding devices again.
∙ Check whether there are any Wi-Fi Kits already added to the SmartThings app.
When there are devices added, first remove them and try again.
