Invisible Threats. Visible Protection.
You can't see a gas leak or carbon monoxide. Grevora detects these hidden dangers in real-time, sounding an 85dB alarm before it's too late. No apps, no Wi-Fi, no confusing setup — just plug it in.
Protection That Never Quits.
Traditional alarms fail when the grid goes down. Grevora features a built-in backup battery that lasts up to 8 hours during blackouts. Plus, the magnetic mount lets you stick it anywhere — from your kitchen to your RV.
Stay Aware at a Glance.
Grevora brings key home conditions together on one clear LED display. Instantly monitor CO, natural gas, smoke, temperature, and humidity. If danger is detected, an 85dB audible alarm and flashing lights will immediately alert you.
