Google Nest Protect (Wired) vs X-Sense SC07-MR Smart Smoke & CO Alarm

The Google Nest Protect (Wired) for a home with mains wiring. It sits on house power, senses smoke and carbon monoxide and adds occupancy, temperature, humidity, ambient-light and motion sensing, spoken warnings, a pathlight and Steam Check. The X-Sense SC07-MR Smart Smoke & CO Alarm counters with an LCD, a five-year warranty and RF interconnection.

Power and features. The Google Nest Protect (Wired) runs on house wiring with a battery backup and carries a full sensor and smart-feature set, while the X-Sense SC07-MR Smart Smoke & CO Alarm is battery only and keeps to smoke and carbon monoxide detection with an LCD.

Only if you replace them with other Protects, because it interconnects just with other Google Nest Protect (Wired) or battery units. It does not link to non-Nest wired alarms through the standard interconnect.

For Wi-Fi and app features, yes, an X-Sense base station is required. The alarm and its RF interconnection with other X-Sense Link+ alarms work without it.

No. The Google Nest Protect (Wired) works with Google Home and Home Assistant, and the X-Sense SC07-MR Smart Smoke & CO Alarm works with Home Assistant only through its base station. Neither supports Alexa, Apple HomeKit, SmartThings or Matter.

A buyer who cannot run mains wiring, wants several battery alarms linked over RF without a base station, and wants combined smoke and carbon monoxide detection.
