Hello,
Please download and use the INKBIRD app instead of the Inkbird smart app.
For the troubleshooting, please refer to this post:

Hello, Fast flash mode or AP (slow blink) mode are both connection methods, they just have different connection steps. If the device is in an environment with strong signal interference, we would recommend using the AP mode. After a successful connection, their functions are the same.
