2000ft Remote Temperature Humidity Monitor, 3 Sensors, Freeze Alert | Reaches far, WiFi-less spaces – shed, greenhouse, garage, barn, cabin, offline & power-loss alerts, 90 dB hub + night light

REACH THE SPOTS WITH NO WIFI – AND NO OUTLET EITHER – The greenhouse across the yard, the detached garage, the barn, the well house down the drive, or the far room at the other end of a large house – the places you most need to watch usually have no WiFi and often no power at the exact spot, which is where ordinary monitors give up, so this long-range temperature and humidity monitor runs each of its three battery sensors up to 2000 ft (line of sight) back to one hub by your router – the sensors need neither WiFi nor an outlet, so you can put them where nothing else will go.
AN ALARM YOU CAN ACTUALLY HEAR ON SITE – Most remote monitors only buzz your phone, which is no help when a heater fails in the greenhouse overnight or pipes start to freeze in an unheated garage, so this monitoring system’s hub sounds a 90 dB alarm and lights a built-in night light the instant a high or low limit is crossed – backed by app and email alerts, iOS Critical Alerts that sound even on silent, an alert delay that cuts false alarms, and remote mute once you’ve seen it.
KNOW THE MOMENT THE MONITORING ITSELF STOPS – A monitor that goes quietly dark in a power cut, a dropped connection or a dead sensor battery is worse than none, because you assume you’re covered when you’re not – a real risk in an unattended cabin, rental or storeroom – so this system alerts you when the hub loses power or WiFi and when a sensor is running low, then tells you again once it’s back online.
DEW POINT AND VPD, NOT JUST A NUMBER – A plain temperature and humidity reading can’t tell a grower whether mold or tip-burn is coming, or a reptile keeper whether the enclosure is truly right, so this wireless thermometer and hygrometer also works out dew point and VPD (vapor pressure deficit) in the app – the kind of professional climate insight most gateways and long-range rivals simply don’t provide.
KEEP DAMP AND MOLD OUT OF WHAT YOU STORE – Temperature isn’t the whole story in a basement, a wine cellar or a room full of instruments, documents or collectibles, where creeping humidity quietly warps wood, rusts metal and grows mold, so this WiFi hygrometer tracks the humidity too and alerts you the moment it climbs past the level you set, so you can run the dehumidifier before any damage starts.
NO GATEWAY TO BABYSIT, NO MONTHLY FEE – Some systems make you keep a separate gateway powered right next to every sensor, and cellular monitors bill you month after month, so this system runs all three sensors on a single hub with no per-sensor gateway and no subscription of any kind – you buy it once and it’s yours.
TWO YEARS OF HISTORY, SHARED ACROSS THE HOUSEHOLD – Spotting a slow drift or proving a cold spell happened means having the record, so this temperature data logger keeps up to two years of temperature and humidity history you can export to CSV anytime; one hub is expandable up to 100 sensors, so you can add more as you take on new rooms and buildings, and admin and user accounts let everyone in the family or team share access and see each spot’s readings in real time.
GOOD TO KNOW – WHERE TO PLACE THE SENSORS – These sensors read the air in dry, sheltered, above-freezing spaces, so keep them out of soaking-wet or misting spots and do not put them inside a fridge or freezer – they are not waterproof, and condensation plus sub-freezing cold will shorten their life; if you need food-safety monitoring inside a fridge or freezer, choose a model with a waterproof probe instead.
