In many commercial buildings, industrial sites, campuses, and municipal projects, the real challenge is not whether an IoT platform exists. The real challenge is how to connect a large number of existing field devices reliably, quickly, and cost-effectively.
Water meters, electricity meters, heat meters, temperature and humidity sensors, level sensors, fans, pumps, valves, power cabinets, PLCs, and DIDO controllers are often distributed across basements, equipment rooms, pipe wells, rooftops, pump stations, factories, and remote sites. These devices may use RS-485, M-Bus, Modbus, DL/T645, dry contact, pulse output, 4–20mA, or other interfaces and protocols.
For customers, the key questions are very practical:
Can these existing devices be connected without major reconstruction?
Can the system run stably in complex environments?
Can deployment and maintenance costs be controlled?
Can the collected data truly support daily operations?
Manthink’s wireless IoT retrofit solution is designed to solve these problems.
Common Pain Points in Existing Projects
1. Too many legacy devices and too many interfaces
Most projects are not built from scratch. They are upgrades based on existing equipment. Different devices use different protocols, different wiring methods, and different installation environments. Some devices only provide RS-485, some provide pulse output, some provide dry contact status, and some legacy devices have no networking capability at all.
If every device requires separate development, separate gateways, and separate platform integration, the project cost quickly increases and the delivery cycle becomes much longer.
2. Wiring is difficult and expensive
In old buildings, industrial plants, campuses, and underground spaces, rewiring is often the biggest obstacle. Many monitoring points are far apart or located in places where construction is difficult. Some sites do not allow wall cutting, cable routing, shutdown, or major modification.
As a result, many projects are technically possible but commercially difficult. The cost of wiring and construction can be higher than the value of the monitoring system itself.
3. Manual inspection is inefficient and risky
Traditional operation and maintenance still relies heavily on scheduled inspection. Staff check water levels, equipment status, temperature, humidity, power cabinets, pump rooms, and meters at fixed intervals.
This approach has clear limitations. Problems may occur between two inspections. Abnormal conditions cannot always be detected in time. Labor costs remain high. Data cannot be continuously recorded. After an incident occurs, it is difficult to trace the full history.
4. Data is collected, but not truly useful
Many customers have already tried IoT platforms. However, they often find that data is visible but not easy to use. The interface is too complex, alarm rules are not clear, business users cannot understand the system, and integration with existing systems requires too much custom development.
Customers do not need just another dashboard. They need a complete solution that can connect devices, process data, trigger alarms, support visualization, and integrate with their existing systems.
Manthink’s Wireless IoT Solution
Manthink provides a complete wireless IoT retrofit solution based on ThinkLink IoT platform, LoRaWAN wireless network, EdgeBus edge protocol capability, and multiple types of data acquisition devices.
The solution includes four layers.
The first layer is field equipment. This includes meters, sensors, industrial instruments, fans, pumps, valves, PLCs, power cabinets, and DIDO controllers.
The second layer is wireless data acquisition. Different interfaces can be connected through different Manthink devices. For example, RS-485 and Modbus devices can be connected through KC11 or KC21. M-Bus heat meters can be connected through KC22. Dry contact, pulse signals, door status, meter pulses, and equipment status can be connected through KS32. 4–20mA, 0–10V, and industrial instruments can be connected through KS31. Temperature, humidity, and water leak monitoring can be connected through KS52.
The third layer is the LoRaWAN gateway. Field data is transmitted wirelessly to gateways such as GDI51 or GDO51, and then forwarded to ThinkLink or the customer’s existing platform. LoRaWAN is well suited for long-distance, low-power, low-data-rate, and distributed IoT scenarios, especially where wiring is difficult.
The fourth layer is the ThinkLink IoT platform. ThinkLink provides device management, data parsing, alarm configuration, visualization dashboards, historical data, remote configuration, permission management, and system integration. Customers can monitor device status, configure parameters, set alarm rules, analyze trends, and forward data to third-party systems.
Business Value for Customers
1. Lower construction cost
Wireless connectivity reduces the need for complex wiring. This is especially valuable for underground wells, pump rooms, equipment rooms, pipe wells, campuses, old buildings, and remote sites. Customers can upgrade existing assets without large-scale reconstruction.
2. Faster project delivery
With standardized hardware, configurable data models, and platform-based management, projects can be delivered faster. System integrators can reduce custom development work and complete device connection, data parsing, alarm configuration, and dashboard setup more efficiently.
3. Better operational safety
Water level overflow, water leakage, equipment failure, abnormal temperature and humidity, power issues, door status changes, and pulse metering anomalies can all be monitored in real time. Instead of discovering problems after they happen, customers can receive early warnings and reduce operational risks.
4. Less manual inspection
The system can replace a large amount of repetitive inspection work. Operation teams no longer need to visit every monitoring point frequently. They can view status centrally and respond only when an alarm or abnormal trend appears.
5. More valuable data
ThinkLink does more than collect data. It supports parsing, filtering, alarm processing, visualization, and data forwarding. Customers can view data by device, area, system type, or business scenario. The data can also be integrated with BMS, SCADA, energy management systems, property management systems, or third-party platforms.
6. Easier long-term maintenance
Long-term maintenance is critical for IoT projects. Manthink’s solution supports remote parameter configuration, device status monitoring, reporting interval settings, and platform-side management. This helps reduce on-site maintenance and improves the sustainability of large-scale deployments.
Typical Application Scenarios
Smart building and property management
The solution can be used for sewage well level monitoring, equipment room temperature and humidity monitoring, water leak detection, power distribution status, fan and pump status, door contact monitoring, and energy metering. Property managers can detect risks earlier and reduce manual workload.
Campus and industrial equipment monitoring
The solution supports distributed equipment status collection, DIDO controller access, PLC data reading, fan and pump monitoring, motor status monitoring, and power cabinet monitoring. Operation teams can view field equipment centrally and respond to abnormalities in time.
Remote metering and energy data collection
The solution can be used for water meters, electricity meters, heat meters, and gas meters. LoRaWAN wireless communication helps solve the problems of manual meter reading, difficult wiring, and discontinuous data collection.
Municipal and underground monitoring
The solution is suitable for underground wells, manhole status, water leakage, pump stations, pipe networks, and remote utility sites. Low-power wireless devices can be deployed in locations with limited power and communication conditions.
