Google Home app adds local Matter control for Philips Hue smart lights

What is new

Google has released an update to the Google Home app that improves local network control for Matter-enabled devices, specifically including Philips Hue lights [2]. According to Google, existing Philips Hue bridges will automatically upgrade in the background to allow local Matter control through Google Home hubs [2]. This update is intended to provide faster response times and better reliability for these devices without requiring users to re-pair them [2]. Additionally, the update includes a visual redesign of core controls for third-party switches, plugs, and lights [2].

Beyond this specific software update, the technology for smart homes relies on different connection methods. Many devices use Wi-Fi to connect to cloud servers, but others use local hubs or mesh standards like Thread, Zigbee, or Z-Wave [1]. Thread, Zigbee, and Z-Wave are low-power, low-bandwidth radio standards that allow a hub to connect many accessories at once [1]. Some Wi-Fi accessories can also function as Thread “border routers” [1].

How to use it

For users with Philips Hue lights, the transition to local Matter control through the Google Home app happens automatically in the background [2]. Users do not need to perform any re-pairing steps to enable this feature [2]. To maintain smart home functionality during an internet outage, devices should be set up to use a local hub rather than relying solely on Wi-Fi and cloud servers [1]. For example, Apple Home users can use HomePods or Apple TVs as hubs to enable local automations [1].

Limits and privacy

There are several technical and practical limits to maintaining a smart home during an internet outage:

• Connectivity Limits: Wi-Fi accessories that connect directly to cloud servers may fail to work or may not follow scheduled automations if the internet or router goes down [1].
• Automation Limits: Local hubs cannot process automations that require live data, such as current weather conditions, or those that involve sharing data remotely [1].
• Bandwidth Limits: Low-power mesh standards like Thread, Zigbee, and Z-Wave have low bandwidth, which limits them to simpler devices like sensors, locks, and lights [1].
• Hardware Availability: Not all smart accessories are available in a hub-compatible format [1].
• Cost: While whole-home battery backup systems can keep a smart home running, these systems can cost thousands or tens of thousands of dollars [1].
• Security: If internet outages are frequent, security systems may require cellular backup to remain reliable [1].
