Hi there, I will upgrade my existing roller shades, equipped with the motion blind CM 20 wifi bridge. Recently Motion blinds launched the new matter bridge CM-55 combined with the matter motors for the rolled shades. Is it necessary for me to purchase the CM-55 matter bridge as well? I have the M3 Hub in place. It would be great not to purchase another hub again…

Theoretically, it should be okay to connect Matter motors with the M3. Maybe you can give it a try and report to the Aqara support team if there’s a connection issue?
@chen1 Hi there! Great question. From what we know, the Aqara Hub M3 supports standard Matter protocol devices, including those using Matter over Wi-Fi, Ethernet, or Thread. Additionally, the Aqara Home app can add Aqara or third-party Matter devices, and the M3 Hub acts as a Matter controller for such devices.
If the new Matter motors for your roller shades are standard Matter devices, your existing M3 Hub may potentially work without needing the CM-55 bridge. However, since the reference information doesn’t specifically mention the Motion Blinds CM-55 bridge or its compatibility with Aqara hubs, we recommend verifying if the motors are standard Matter devices (e.g., checking their setup requirements or consulting the manufacturer).
If you’re still unsure, reaching out to customer service for further clarification would be a good step. Hope this helps, and let us know how it goes!
Note: The above is based on available reference information. For device-specific compatibility, please confirm with the manufacturer or customer service.
@chen1 Hi there! Let’s break this down. Your M3 Hub is a Matter controller, which supports standard Matter protocol devices including Matter over Wi-Fi, Ethernet, and Thread. To connect Matter devices, you can scan the device’s Matter QR code in apps like Aqara Home and select the M3 Hub as the controller.
Since you already have the M3 Hub, it might not be necessary to purchase the CM-55 bridge if the new Matter motors for your roller shades are standard Matter devices. However, do note that some brand-specific Matter devices may connect through their proprietary bridges, so it’s a good idea to check if the Motion blinds’ Matter motors are native standard Matter devices or require their own bridge.
If you try connecting them via the M3 Hub, feel free to share your experience here—your insights could help other community members! If you run into issues, you can also reach out to the device manufacturer for clarification on compatibility.
Hope this helps, and fingers crossed you can skip the extra hub!

Since you already have the M3 Hub, you might not need the CM-55 bridge if the new Matter motors for your roller shades are standard Matter protocol devices. However, do note that some brand’s Matter-enabled devices connect through their proprietary Matter Bridge, so it’s worth checking if the new motors require the CM-55 specifically.
If the motors are standard Matter devices, follow the setup steps: open the Aqara Home app, go to “Home” > “+” > “Add Device” > “Matter Device,” and scan the QR code to complete setup .
Hope this helps! Feel free to share how it goes—community insights are always valuable. If you run into specific issues, checking with the device manufacturer for QR code or compatibility details could also be helpful.
