Mesh Monitoring for Building Engineering Systems
A self-organizing wireless mesh network for heat, water, and electricity monitoring in multi-apartment buildings — no subscription, no cable runs, no monthly fees.
Why traditional approaches fail
Opaque metering
Property managers have no visibility into actual consumption per building — only estimated normatives.
Overpayment up to 40%Failures without warning
Pipe bursts, freezing, electrical overloads — discovered only after damage has occurred.
Response: hours to daysExpensive infrastructure
Wired monitoring systems require thousands of meters of cable and structural disruption.
6–10 $/m of cableLoRaWAN gateways — single point of failure
Centralized gateways: failure of one device disconnects an entire monitoring segment.
100% dependencyNo data for residents
Tenants cannot see real-time consumption or dispute meter readings.

IIOT-AMS MeshSens
Wireless multi-function data acquisition node
ROSSMA IIOT-AMS MeshSens is an industrial IoT node with built-in Mesh topology support at 868 MHz. Each device simultaneously acts as a sensor, repeater, and router — delivering fault tolerance without a central gateway.
- Radio interface Mesh 868 MHz, AES-128, OTA updates
- Wired inputs RS-485 / Modbus, 4–20 mA, DI/DO
- Power Battery up to 5 years / 5–30 V DC / solar
- Protection IP65, −40 … +85 °C
- Certificates EAC (Russia/EAEU), CE
- Manufacturing Made in Russia
Mesh architecture — no single point of failure
Every node is a repeater. The network self-heals when any element fails.
Technical specifications
- Frequency 868 MHz (ISM, no RF licence required)
- Topology Full Mesh — up to 50 nodes/cluster
- Node range 200–1 500 m (depends on urban density)
- Power Battery up to 5 years or solar panel
- Protection IP65, −40 … +85 °C
- Interfaces RS-485 / Modbus, 4–20 mA, DI/DO
- Encryption AES-128, OTA firmware updates
Mesh advantages
Self-healing
When a node fails, packets are automatically rerouted through neighbours.
Scalability
Adding new sensors requires no cabling or additional gateways.
No SIM cards
No monthly fees for NB-IoT / LTE-M cellular traffic.
Works offline
Local data storage in nodes when server connectivity is lost.
What the system monitors
Heat meters
Integration with MULTICAL, VKT-7, ST-15 via M-Bus / RS-485. Archive, daily and hourly readings.
Water meters
Cold and hot water: ultrasonic and pulse sensors. Leak detection via delta method.
Electricity
AMR/SCADA: per-phase metering, power factor, voltage sags, imbalance analysis.
Stairwell temperature
Air temperature monitoring in stairwells and basements. Pipe freeze prevention.
System pressure
Pressure monitoring in DHW and heating mains. Automatic fault alarms.
IHP & CHP units
Monitoring of individual and central heat supply units.
Monitoring subsystems
- Heat meter readings (VKT-7, MULTICAL 302/403, ST-15)
- Supply and return temperature monitoring: T1, T2, ΔT
- Heat carrier volume: V1, V2, ΔV — leak detection
- Pipeline pressure P1 and P2
- SCADA integration via Modbus TCP
- Historical data: hourly / daily / monthly / yearly
- Contract parameter violations — automatic alerts
- Balance per building, stairwell, IHP
- Ultrasonic and woltmann CWS and HWS meters
- Per-apartment and per-stairwell water balance
- Leak detection: delta method and statistical anomalies
- Water supply network pressure monitoring
- HWS temperature control ≥55 °C (sanitary standards)
- Automatic meter reading transmission
- Hourly archive; export to municipal utility platforms
- Multi-tariff electricity metering (T1/T2/T3)
- 3-phase monitoring: voltage, current, power factor, active power
- Imbalance detection between main meter and flat sum
- Voltage sag and overload recording
- Common area lighting: fixture groups, violations
- Automated lighting control (relays, dimmers)
- AMR integration and billing system API

|---|---|---|---|
| Heat (IHP imbalance) | $2 500–3 300 | $400–700 | $2 100–2 600 |
| CWS/HWS (leaks) | $1 100–1 600 | $200–350 | $900–1 300 |
| Electricity (common area) | $1 600–2 500 | $950–1 400 | $700–1 100 |
