Hello,
The red indicator is a status indicator for the fan, it is normal to display a red indicator if the fan is not operating.
Please connect ISC-027BW to the INKBIRD app first, you can check the WIFI connection status by the blue WIFI indicator.
After connecting, please insert the probes into ISC-027BW and set the target temperature. If the fan is on, the red indicator light will change to green indicator light.
