Bosch Twinguard smoke detector, hopes to reduce False alarms


Bosch is refining the sense of smell on its Twinguard smart smoke detector with the goal of reducing false alarms. The Twinguard not only includes photoelectric smoke detectors, but senses air quality to help determine when there’s a real emergency.

When the alarm sounds, the Bosch Twinguard will send you a push notification on your phone, and it can trigger other smart devices in the Bosch Smart Home system. You could have your Philips lights blink when the smoke alarm sounds, for example.


Outside of emergency situations, the Twinguard monitors temperature, humidity and general air quality by detecting volatile organic compounds (VOCs), so it stands to be the most knowledgeable smoke detector on the market. The Nest Protect similarly offers app-enabled smarts, and both the Nest and Bosch detector distinguish between different types of smoke to help make an informed decision about when to sound the alarm. The Nest Protect, however, doesn’t monitor VOCs.

Bosch’s Twinguard is one of three new smart home products Bosch introduced today at the IFA trade show here in Berlin. The company best known for its dishwashers is clearly making a concerted push into the fully connected home. When Bosch first announced the Bosch Home Connect app, the goal was to encompass everything. Now, with a wider variety of devices, we’re starting to see that plan come to fruition.
