Google Home 4.8 Adds Smart-Button Automations, New Triggers and a Nest Cam Fix

The rollout expands physical control in the app, with effective use depending on device compatibility.

Overview

  • The update is rolling out on Android and iOS and enables physical smart buttons as automation starters with single or multi-press, long press, and long‑press release.
  • New starters and conditions include humidity thresholds, robot vacuum docking status, battery state, and binary device states such as open or closed and leak or no leak.
  • Automations can now set smart lights to specific colors or color temperatures.
  • Google says the release includes a foundational fix aimed at resolving recurring “video not available” errors for Nest Cam playback.
  • Supported button models are not yet clear, with early tests reporting IKEA’s BILRESA not working and the button starter unavailable in Gemini for Home features.
