# Retrofit Smoke Detectors This Smart Battery Turns Old Smoke Alarms Into WiFi-Connected Versions By Alyson Wyers | Published 2014-11-14 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/smart-battery References: [mashable](http://mashable.com/2014/11/12/roost-smart-battery/) & [kickstarter](https://www.kickstarter.com/projects/roost/the-roost-smart-battery-smarten-your-smoke-alarms) This smart battery indicates how you can transform your existing house into one integrating The Internet of Things. From startup [Roost](https://www.trendhunter.com/trends/smartdesigned-chicken-coops), the smart battery for smoke alarms is currently looking for investors via crowdfunding platform [Kickstarter](https://www.trendhunter.com/trends/airnotis). Your old smoke alarm and current smartphone can be used alongside Roost's WiFi-connected product to "retrofit your way into an intelligent, connected home" while also offering peace of mind at the same time. This invention turns your existing smoke detector into a smart one with the help of a [companion app](https://www.trendhunter.com/trends/switchbot-safety-alarm). In the event you are out, the app will notify you if the alarm goes off and provides you one-touch access to emergency numbers. It even avoids the annoying chirping sound by warning you weeks in advance. ## Trend Insights (Trend Hunter) - Score: 1.8/10 - Popularity: 21% | Activity: 24% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) ## Key Themes ### What Makes This Trend Stand Out - **Smart Home Retrofitting:** The trend of retrofitting old homes with smart technologies drives innovation opportunities in home automation, security, and energy efficiency industries. - **Integrating Iot Into Existing Infrastructure:** The trend of integrating IoT into existing infrastructure fuels innovation in retrofit technologies and IoT service providers. - **Crowdfunding for Iot Innovations:** The trend of crowdfunding for IoT innovations presents opportunities for startups in IoT to leverage crowd support and finance their product development. ### Sectors Adopting This - **Home Automation:** The home automation industry stands to benefit from the trend of retrofitting old homes with smart technologies as new demand emerges in the market. - **Security Services:** The security services industry could leverage the trend of smart home retrofitting to produce innovative security solutions for homes. - **Crowdfunding Platforms:** Crowdfunding platforms are key players in fueling the trend of crowdfunding for IoT innovations, opening up opportunities for startups in IoT to get financing for their products. ## Related on Trend Hunter - [Smart Home Safety Alarms](https://www.trendhunter.com/trends/first-alert-smart-smoke-carbon-monoxide-co-alarm.md) - [Smart Home Smoke Detectors](https://www.trendhunter.com/trends/ecoey-smoke-detector.md) - [Collaborative Smoke Detector Lines](https://www.trendhunter.com/trends/kidde.md) - [Intelligent Processor Smoke Alarms](https://www.trendhunter.com/trends/meross-ma151-smart-smoke-alarm.md) - [Bird-Like CO2-Monitoring Devices](https://www.trendhunter.com/trends/birdie-1.md) - [Smoke Alarm Home Alerts](https://www.trendhunter.com/trends/sound-recognition.md) - [Food-Delivering Smoke Detectors](https://www.trendhunter.com/trends/mcdelivery-detector.md) - [Emergency Smart Home Batteries](https://www.trendhunter.com/trends/smart-home-battery.md) - [AI-Powered Smoke Detectors](https://www.trendhunter.com/trends/vape-detectors.md)
