Wemo doorbell HomeKit dropouts point to mDNS failure
The Wemo Smart Video Doorbell WDC010 sometimes shows “No Response” in Apple HomeKit. Wi-Fi, the home network, and the eero HomeKit firewall have been ruled out. The doorbell’s HomeKit server keeps running, but its responder stops answering, so HomeKit cannot find the device again after a brief connection break.
The device is on firmware 1.0.16, which is the final build. Belkin shut down the Wemo cloud on January 31, 2026, so an official fix is not expected. A power cycle always brings the doorbell back, which points to a stuck firmware state rather than dead wireless .
The dropouts may happen after roaming between eero nodes or after a HomePod home hub handoff. The proposed repair path is to dump the device flash, patch the mDNS responder, and reflash it.
