Watch over your home & office — even when you're away
Battery-powered cellular sensors monitor temperature, humidity and water leaks around your home, home office or small office. No WiFi, no wiring — just place, pair, and get instant alerts the moment something drifts out of range.

Peace of mind, around the clock
Designed for the places you live and work — not just industrial sites.
No WiFi, no wiring
Works anywhere with mobile coverage — apartments, basements, server closets and rental units. Batteries last up to 4 years.
Alerts before damage
Temperature drifts, humidity spikes or a leak starts — you get an instant app push and email the moment values leave your safe range.
Set-and-forget simple
Place the sensor, scan to pair, set thresholds once. Monitor 24/7 from the app or web dashboard and export history any time.
Two sensors. One watchful system.
Purpose-built hardware, a unified cloud platform, and alerts that reach you anywhere.
