Why is my indoor unit is beeping and won't connect to Alexa?

Overview

If your indoor unit is beeping when attempting to connect to Alexa — or the connection fails entirely — the issue is often related to the USB dongle placement or setup process. Follow the steps below to resolve the problem and get connected successfully.

Important Notes Before You Start

The Senville Alexa USB dongle does not work with the Senville app. It must be set up directly via the Amazon Alexa app.
A beeping indoor unit during setup is typically caused by the dongle being improperly inserted.

Step-by-Step Troubleshooting

Step 1: Remove and Reinsert the USB Dongle

Turn off the mini split unit using the remote control.
Lift the front panel of the indoor unit to access the USB port.
Carefully remove the USB dongle.
Re-insert it firmly and fully into the USB port until it is fully seated. The flat side of the dongle should face outward.

Step 2: Check for Beeping

After reinserting the dongle:

The beeping should stop after a few seconds if the dongle is inserted correctly.
If the unit continues to beep, remove the dongle and try reinserting it again with a firm push — be sure it's not loose.

Step 3: Connect to the Alexa App

Open the Amazon Alexa app on your smartphone.
Tap “Devices” → “+” → “Add Device”.
Choose “Other” or “Smart Home Device” depending on your app version.
Follow the on-screen instructions to complete the pairing process.

Step 4: Confirm Successful Connection

Your unit should stop beeping once the dongle is correctly inserted and paired.
You should see the device appear in your Alexa app dashboard.

Still Not Working?

If your mini split continues to beep or does not appear in the Alexa app:

Verify that your USB dongle is running the latest firmware version.
If needed, reset the dongle to factory settings using a pin or paperclip (check your dongle manual for reset location).
Reinstall your Alexa kit by removing the device from the app and repeating the setup steps.
