Halo Smart Labs
Halo is the world’s first device to combine commercial-grade smoke detection with a carbon monoxide alarm in one unit. If it senses a problem, a voice alert will instantly tell you what’s wrong. The ring of light illuminates — red for fire, amber for carbon monoxide — and you’ll get an alert on your phone. Oh, and don’t worry about getting out of bed for a dead battery; ours lasts for 10 years.
