meross wireless smoke and CO detector hits new $21 low (Reg. $43), more smart devices from $20

The official meross Amazon storefront is offering its Interconnected Smoke and Carbon Monoxide Detector Combo for $21.49 shipped. Down from its $43 price tag, it saw a few discounts over the last year, with Christmas sales seeing the biggest price cut to $29. Today’s deal comes in as a massive 50% markdown off its going rate that beats our previous mention by $8 and lands at a new all-time low. This smoke and carbon monoxide detector is designed to provide full coverage of your home by wirelessly connecting with up to 11 other detectors, keeping you updated through its multiple alert modes, LED indicators, or with its loud siren. It features a user-friendly LCD screen that gives you real-time data like the CO levels (from 30 to 999 PPM), battery status, and even operational updates as they become available.
