Holio detects the exact moment a window is open during rain and alerts your front desk before damage is done. Heating pauses automatically. No staff intervention needed.
A guest opens a window and forgets to turn the radiator down. It rains. The floor gets wet, the heating runs at full power, and by the time staff notice, the damage is done. This happens dozens of times a month in a typical hotel.
Room 304: window open since check-in at 2pm. Rain started at 4pm. Staff found wet floor during evening round at 7pm. 3 hours of heating wasted. €18 cleaning bill. Guest complaint.
Room 304: window open at 2pm, noted. Rain starts at 4pm, alert sent to front desk within 30 seconds. Heating paused. Staff visit room at 4:05pm. No damage. Zero energy wasted.
A weatherproof rain sensor on the roof detects precipitation. When both conditions are true, an alert fires.
The magnetic contact sensor on each window registers open/closed state in real time, 24/7.
A push notification reaches the front office app within 30 seconds. Room number, floor and everything they need.
Heating and cooling for that room pause until the window is closed. No manual override needed.
No drilling into frames, no power cables. The Holio window sensor sticks to any window type with industrial adhesive and runs for 5 years on a single battery.
"The window sensor alone was worth it. Front desk gets notified before guests even notice it's raining. And the heating just turns off automatically."
