Had a pilot light issue with our furnace last winter and had no idea until HomeGuard started blaring at 2am. Genuinely might have saved us from a much worse situation. Thank goodness!
What does the HomeGuard actually monitor?
What does the HomeGuard actually monitor?
HomeGuard's 6-in-1 Threat Detector keeps a constant watch over the things you can't see or smell in your home. It tracks temperature, humidity, and overall air quality, while its electrochemical and photoelectric sensors flag combustion-related vapors near stoves, heaters, and fuel-burning appliances, along with airborne particles from cooking, fireplaces, or burnt food. Everything is displayed on the 2.8-inch color screen so you always know exactly what's going on in the room.
Does it work during a power outage?
Does it work during a power outage?
Yes. HomeGuard's 6-in-1 Threat Detector runs on a dual power system, so it stays fully operational even when the lights go out. Plug it in for everyday use, and if the power cuts, the built-in battery automatically kicks in and keeps monitoring for up to 8 hours.
How do I know it's working?

My mother in law got me one of these for the kitchen and honestly it's become my favorite gadget in the house lol. Love that I can just glance at the screen and see temp, humidity, and air quality all at once.

Didn't think I'd use this as much as I do. Ended up liking it so much I bought a second one for the garage.

Real Homeowners. Real Peace of Mind.
Caught a Gas Leak Before It Got Dangerous
Our stove was leaking gas and I had zero clue until HomeGuard started going off. It's paid for itself ten times over just for that one alert.
One Device, Four Fewer Gadgets
I used to have a separate thermometer, hygrometer, and two different alarms cluttering the kitchen. HomeGuard replaced all of it and looks way cleaner on the wall.
Worth It For Us
Wasn't sure a detector could feel 'techy,' but the display alone makes it feel like a serious upgrade. Setup took no time at all and it's been rock solid since.
FAQs

How do I turn on my HomeGuard for the first time?
How do I turn on my HomeGuard for the first time?
Press and hold the power button for 10 seconds. Once the indicator lights come on, your HomeGuard's 6-in-1 Threat Detector is powered on and ready to start monitoring. If it doesn't power on right away, it may need to charge for over an hour before the battery can activate.

Can I keep it plugged in permanently, or does it need to run on battery?
Can I keep it plugged in permanently, or does it need to run on battery?
You can keep it plugged in around the clock for continuous everyday monitoring, or detach it and rely on the built-in battery for up to 8 hours when you're on the move or during a power outage. The dual power system automatically switches over, so you're never left unprotected.

How long does the battery last on a full charge?
How long does the battery last on a full charge?
A full charge gives you up to 8 hours of battery backup, which is more than enough to cover most power outages. The battery kicks in automatically the moment power is lost, so there's no manual switch to remember.

Does the magnetic mount work on any surface, or just metal?
Does the magnetic mount work on any surface, or just metal?
The magnetic mount adapter is designed for metal surfaces like refrigerators, RV walls, and metal cabinets for a fast, secure hold. For non-metal surfaces, you can use the plug-in outlet mount instead, so you're covered no matter where you want to install it.

How often does the HomeGuard check the air in my home?
How often does the HomeGuard check the air in my home?
HomeGuard's 6-in-1 Threat Detector uses periodic sampling mode, automatically checking your air roughly every 10 seconds. This keeps the sensors accurate while conserving battery life, so you get reliable, ongoing awareness without constant power drain.

Does it require a phone app or Wi-Fi to function?
Does it require a phone app or Wi-Fi to function?
No app or Wi-Fi needed. HomeGuard's 6-in-1 Threat Detector works right out of the box, showing everything you need to know directly on its built-in 2.8-inch display with audible and visual alerts, so setup takes minutes and there's nothing extra to connect.

Can I take it with me when I travel or move?
Can I take it with me when I travel or move?

Jenny L. Verified BuyerWe travel with our RV constantly and I was always nervous about carbon monoxide with the propane heater running. HomeGuard goes wherever we go thanks to the magnetic mount and battery backup. Haven't had a scare since we got it.
-
Robert K. Verified BuyerHonestly thought this was going to be another gimmicky gadget that ends up in a drawer. Three months in and it's mounted permanently in my kitchen, and it caught a burnt dinner alert before my smoke detector even noticed.

Ashley P. Verified BuyerSolid build, clear display, does its job without any fuss.

Tom D. Verified BuyerPower went out during a storm last month and I completely forgot HomeGuard was even running on battery. Came downstairs and it was still tracking everything on the display like nothing happened. That 8-hour backup is no joke.
