Echo and Dot devices connect through your Wi-Fi network and your Amazon account, not directly to each other
When you set up an Echo or Dot, it joins your home Wi-Fi and links to your Amazon account. Once both devices are on the same network and logged into the same account, they can communicate with each other — but the connection runs through Amazon's servers, not a direct cable or Bluetooth link between the two speakers.
This matters because it means both devices need working internet access to talk to each other. If your Wi-Fi goes down, they stop communicating. It also means Amazon can see and log what you're doing with both devices, which is worth understanding before you set them up.
The practical result is straightforward: you can play music on one device and stop it on another, move a song from one room to the next, or control both speakers as a group from a single voice command. But that convenience comes with the trade-off that your activity flows through Amazon's infrastructure.
Key Takeaways
- Both devices must be on the same Wi-Fi network and signed into the same Amazon account to work together.
- You can group Echo and Dot devices so one voice command controls multiple speakers at once.
- Connecting devices requires the Alexa app on your phone — you cannot do it through the speakers alone.
- Once grouped, you can move music between rooms, adjust volume on each speaker separately, or play the same thing everywhere in your home.
- If your Wi-Fi drops, the devices lose the ability to communicate with each other until the connection returns.
What you need before you start
Have your Amazon account password ready. You will need to sign into the Alexa app on your phone, and both Echo devices must be logged into the same account. If you share a home with someone else and want them to control the speakers too, Amazon lets you add them as a household member later — but the initial setup needs one account owner.
Both devices should already be plugged in and connected to your Wi-Fi. If either one is not yet on your network, complete that setup first through the Alexa app. The app will walk you through connecting each device to Wi-Fi before you can group them.
You do not need any cables between the devices. Everything happens over your home network.
How to group devices in the Alexa app
Open the Alexa app on your phone and tap the Devices button at the bottom right. You will see a list of all your Echo and Dot devices. Tap the plus sign in the top right corner and select Create Speaker Group.
Give the group a name — something like "Living Room and Kitchen" or "Downstairs" works well. Then check the boxes next to each device you want in the group. Tap Create when you are done. The app will take a few seconds to set up the connection.
Once the group exists, you can play music on it by saying "Alexa, play jazz in the living room and kitchen" or by tapping the group name in the app and hitting play on any song or station. All devices in the group will play the same thing at the same volume.
Controlling volume and playback separately
When devices are grouped, they play the same content, but you can adjust the volume on each speaker independently. In the Alexa app, tap the group name, and you will see a slider for the overall group volume plus individual sliders for each device. Turn one speaker quieter without affecting the others.
If you want to stop music on just one device while the group keeps playing, tap that device's name in the app and hit pause. The other speakers in the group will keep going. You can also ungroup devices at any time by going back to the speaker group settings and unchecking the ones you want to remove.
What happens to your data when devices are connected
When your Echo and Dot devices are grouped and communicating, Amazon logs which devices are playing what, when they play it, and how long they play. This information is tied to your Amazon account and stored on Amazon's servers. You can see your listening history in the Alexa app under Settings > Alexa Privacy > Review Voice History.
You can delete individual recordings or turn off voice history entirely, though doing so may limit some features. If you want to prevent the devices from recording at all, you can press the mute button on each speaker — a light will turn off to show it is muted — but then voice commands will not work until you unmute it.
The connection between your devices and Amazon's servers is encrypted, meaning the content of what you are playing is not readable to others on your Wi-Fi network. However, the fact that you are using the devices, and when, is visible to Amazon.
Troubleshooting when devices will not connect
If your devices are not showing up in the Alexa app, or if grouping fails, start by checking that both are on the same Wi-Fi network. Open the Alexa app, go to Devices, tap each device, and look at the Wi-Fi network name listed under Device Settings. If one is on your guest network and the other is on your main network, move them to the same one.
Next, restart both devices by unplugging them for 30 seconds, then plugging them back in. Wait for the light ring to turn blue (which means it is ready), then try creating the group again. If that does not work, sign out of the Alexa app completely, close it, and sign back in.
If devices still will not group, check whether your router is blocking communication between devices on the same network. Some routers have a setting called "AP Isolation" or "Client Isolation" that prevents devices from talking to each other. Log into your router settings (usually through a web browser or the router's app) and turn this setting off if it is on.
When you might not want to group devices
Grouping works well if you want the same music playing everywhere — a party, background music while cooking, or a podcast throughout your home. But if you want different things playing in different rooms, do not group them. Instead, just say "Alexa, play music in the kitchen" and "Alexa, play news in the bedroom," and each device will play independently.
You also do not need to group devices if you only want to control one at a time. The Alexa app lets you pick which device to send a command to without grouping. Grouping is purely for convenience when you want multiple speakers to act as one.
Frequently Asked Questions
Can I group an Echo with a Dot from a different generation?
Yes. As long as both devices are on the same Wi-Fi network and signed into the same Amazon account, they can be grouped together regardless of which model or generation they are. An older Dot can group with a newer Echo without any problem.
What if I want different people to control different devices?
You can add household members to your Amazon account through the Alexa app under Settings > Account Settings > Household Profile. Each person gets their own login and can control all grouped devices, but Amazon keeps separate listening histories for each person. However, all household members can see and control all devices in the home.
Do I need to group devices to move music between rooms?
No. You can play music on one device, then tap a different device in the app and say "Alexa, play this on the kitchen speaker." The song will pause on the first device and start on the second. Grouping is only necessary if you want the same thing playing on multiple devices at once.
Will grouping devices use more of my internet bandwidth?
Grouped devices stream the same content, so bandwidth use is the same as playing on a single device. If you play different things on different ungrouped devices, that uses more bandwidth because each device is streaming separately.
Can I group devices if they are on different Wi-Fi networks?
No. Both devices must be on the same Wi-Fi network to communicate. If you have a multi-floor home with separate networks, move both devices to the same network first. If your Wi-Fi does not reach both locations, consider a Wi-Fi extender or mesh network to cover both areas.
