Retrofit your rounds.
Visit only when it matters.
Sensors read the gauges, log temperatures and currents, and watch for leaks 24/7 — so unstaffed buildings need fewer scheduled visits.
Keep your existing equipment as-is. Battery sensors you place yourself, a gateway you plug in, and obniz Now for dashboards, alerts and reports. Surveys and installation are available as options.
Challenges
Sound familiar?
Not enough people for daily rounds and on-site staffing
Reading gauges and logging temperatures and currents eats hours every day. Sites without staff need scheduled visits, and work is turned away for lack of people.
Nights and unstaffed hours are a blind spot
Problems are found the next morning or on the next visit. Leaks and outages spread before anyone reacts, and you pay for it in complaints and losses.
Records pile up on paper and in Excel, unused
Logs are scattered by site and impossible to search. No trend analysis, no improvement loop, and quality changes whenever the person changes.
Sensors
A full sensor lineup for
total facility visibility
Leaks, current, vibration, open/close — obniz Now manages the right IoT sensor for every job in one place.
Feature 01
Battery-powered leak sensor, no installation required
Place under pipes, around HVAC units, in ceilings, or in basements to detect leaks and flooding 24/7. Battery-powered with zero wiring work — alerts go out instantly via email, phone, SMS, or Slack.
- No power supply, no wiring — set up in 5 seconds
- Proven in hotels, airports, train stations, and museums
- Prevents equipment damage and business interruption
Feature 02
Contact output and current detection
Just clamp it onto existing wiring to detect equipment activity, downtime, or abnormal current in real time, without contact. Spot output degradation and operational anomalies remotely, with no site visits.
- Attach to existing wiring — no equipment retrofit needed
- Works with elevators, HVAC, pumps, and compressors
- Visualizes runtime, abnormal current, and aging trends
Compressor #2 / Running
Feature 03
Vibration sensor for anomaly detection
Stick it onto motors, fans, or pumps to catch early signs of bearing wear or shaft misalignment. The system learns the normal pattern and alerts you before failure occurs.
- Attach with double-sided tape or magnet
- Captures activity, noise, and vibration patterns together
- Prevents sudden breakdowns and enables planned maintenance
Anomaly Detected
Pump #3vibration anomaly
Feature 04
Time and open/close sensors for room utilization analytics
Visualize room and facility usage patterns from door, window, and cabinet open/close logs. Use occupancy data to optimize energy, layout, and operations.
- Utilization analytics for meeting rooms, warehouses, server rooms, and stores
- Auto-logs open/close timing, dwell time, and usage frequency
- Optimizes HVAC, lighting, and cleaning routes

Coverage
What your staff inspect today, and which sensor takes it over
"In production" means the configuration is running at customer sites. Gauges not listed here can usually be connected if they expose RS232/485, Modbus or a contact output — send us the model number.
| Inspected today | Replaced by | Status |
|---|---|---|
| Refrigerator / freezer / incubator temperature | Battery temperature sensor (magnet mount) | In production |
| Analog pressure, temperature and level gauges | Gauge-reading sensor (stuck on the dial) | In production |
| Digital displays and gauges that cannot be tagged | Camera capture + value extraction | Validated |
| Leaks and pooling (under pipes, drain pans) | Leak sensor (just place it) | In production |
| Outdoor pooling (rooftop drains) | Leak sensor + weatherproof enclosure | Needs PoC |
| Pump / fan / HVAC activity and current Three-phase 200 V panels require a licensed electrician | CT clamp | In production |
| Power draw of plug-in equipment | Smart plug | Validated |
| Running / stopped (vibration on/off) | Vibration switch (magnet mount) | In production |
| Wear on rotating equipment (V-belts, bearings) Needs 1+ month of learning | Accelerometer frequency analysis | Needs PoC |
| Alarm and run contacts (fire panels, elevators) | Contact input / RS485 | In production |
| Door open/close, occupancy | Door and motion sensors | In production |
| Indoor environment (CO2, temp/humidity, pressure) | Environment sensor | In production |
| Location of people and assets | BLE beacons | In production |
| Lighting state and control | KNX / DALI | In production |
| HVAC and BMS values and control | BACnet / Modbus | In production |
| Water and gas meter totals Meters with pulse output only | Pulse input | Validated |
Out of scope: odors, water quality and anything that can only be judged by eye.
Scope
What obniz does, and what we ask of you
Self-service by default: the standard kit needs no construction work. Anything that requires a visit is offered as a priced option.
- ✓ Requirements interview, sensor selection and system design
- ✓ Hardware sales (purchase, not rental), shipped pre-configured
- ✓ Dashboard, alert and report setup
- ✓ Uptime monitoring and low-battery alerts during operation
- ✓ Email and chat support
- ✓ Post-trial review and rollout plan
- + On-site survey (walking the inspection route with you)
- + On-site installation
- + PoC for specific equipment (vibration diagnostics, outdoor leaks, etc.)
- + Integration with your systems (API) and custom screens
- + OEM / resale under your brand
- • Place battery sensors (set, stick or magnet)
- • Provide a power outlet for the gateway
- • Choose Wi-Fi or LTE connectivity
- • Set thresholds and recipients; first response to alerts
- ✗ Electrical work (live wiring, panel work) — we can introduce partners
- ✗ On-site staffing, inspection outsourcing, equipment repair
- ✗ Custom system development from scratch
- ✗ Resale of third-party camera services
Specialized scenario
Leak detection comes built in
Drop-in sensors monitor pipes, ceilings, and HVAC drain lines for water leaks 24/7. Detection triggers instant alerts via email, phone, SMS, or Slack.
Hotels & venues
Detects HVAC drain overflows. Prevents equipment damage and business interruption.
Airports & stations
Catches ceiling leaks early and ties into alarms. Minimizes passenger impact.
Museums & heritage buildings
Protects priceless collections and architecture from water damage. Early detection limits the spread.
Notifications: email / SMS / phone (auto-voice) / webhook / Slack
Predictive maintenance
Catch failures before they happen
Stream operational data into the cloud, detect output degradation and abnormal patterns, and shift maintenance from reactive "fix-when-broken" to planned, condition-based work.
Data capture
Stream connection status, run count, error count, power state, and output values in real time.
Cloud storage
Securely stored in obniz Cloud to track long-term trends.
Anomaly detection
Monitors deviation from baseline and auto-detects degradation and abnormal patterns.
Alerts
Auto-notifies stakeholders via email, phone, or SMS to enable planned response.
Prevent sudden breakdowns
Spot trend-based warning signs and replace parts on schedule. Avoid unexpected downtime.
Optimize maintenance cost
Cut unnecessary scheduled visits. Condition-based maintenance means action only when it is needed.
Consistent quality, whoever is on shift
Decisions are based on numbers and history, not one veteran's instinct — so quality holds when staff change.
