I mapped my smart home traffic, and one device was constantly phoning home

A Ring Indoor Camera integrated into Home Assistant can generate a disproportionate volume of network traffic, specifically DNS requests to Ring’s API. According to a report by MakeUseOf, this occurs because Home Assistant must maintain a constant live feed to support HomeKit Secure Video, resulting in thousands of requests to domains like api.ring.com and api.prod.signalling.ring.devices.a2z.com.

Why are smart home devices “phoning home” so frequently?

Many smart devices rely on cloud-based APIs to function, meaning they constantly check in with a remote server to receive commands or upload data. In the case of the Ring Indoor Camera, MakeUseOf found that the device was responsible for the majority of server requests on a home network, even when the official Ring app wasn’t in use.

This “chattiness” often stems from how third-party integrations work. When a user uses Home Assistant to bridge a Ring camera into Apple’s HomeKit Secure Video, the system doesn’t just wait for a trigger. It effectively captures live video 24/7 via the Ring API to detect movement and record clips. This creates a continuous loop of DNS requests that can clutter a network and raise privacy concerns.

What is the shift toward “Local-First” smart homes?

The reliance on cloud APIs is driving a trend toward local-first control. Users are increasingly moving away from “cloud-dependent” hardware—which stops working if the company’s servers go down—toward devices that process data on the home network.

The industry is responding with standards like Matter and Thread. According to the Connectivity Standards Alliance (CSA), Matter aims to create a unified, local language for smart devices. This reduces the need for “bridges” like Home Assistant to constantly poll a cloud API, as the device communicates directly with the local hub.

Local Control vs. Cloud Integration

The difference in network behavior is stark. A cloud-integrated camera sends data to a remote server before it ever reaches your phone. A local-first camera sends data directly to a local NVR (Network Video Recorder) or hub. This eliminates the thousands of DNS requests to external domains and keeps the video feed inside the house.

How can users protect their network privacy?

Network monitoring is becoming a standard practice for privacy-conscious homeowners. Using tools like Wireshark for deep packet inspection or Pi-hole for DNS tracking allows users to identify “leaky” devices.

The MakeUseOf report highlights a critical trade-off: interoperability often comes at the cost of privacy. By forcing a Ring camera to work with HomeKit, the user created a constant stream of data to Ring’s servers. The solution is often to purchase hardware that natively supports the desired ecosystem, removing the need for an intermediary that must “trick” the cloud API into providing a constant stream.
