Interoperability
Make compatible sensor information more accessible - Different Sensors Working Towards the Same Decision hello@tigertek.io
Core Levels of Interoperability
To work properly, sensor systems must align across several layers:
Network / Connectivity: Physical hardware and transport protocols (e.g., Wi-Fi, Bluetooth, Zigbee, LoRaWAN, cellular) must link together or connect through a common gateway. [1, 2]
Syntactic (Data Format): Data must be structured in machine-readable formats (e.g., JSON, XML, RDF) so systems can parse the payload syntax. [1, 2]
Semantic (Meaning): Shared vocabularies, ontologies, and metadata standards ensure that a measurement (such as "temperature" or "pressure") is interpreted identically by different systems. [1, 2]
Key Standards and Frameworks
IEEE & OGC Standards: Organizations like the Institute of Electrical and Electronics Engineers and the Open Geospatial Consortium build foundational specifications for sensor webs and spatial data. [1]
NGSI-LD & RDF: Common linked-data frameworks and schemas used to describe context and sensor properties. [1]
EU Interoperability Framework: Policies like the Interoperable Europe Portal promote FAIR data principles (Findable, Accessible, Interoperable, Reusable) and Minimal Interoperability Mechanisms. [1, 2]
Major Challenges
Vendor Lock-in: Proprietary ecosystems restrict devices from communicating outside their brand.
Protocol Fragmentation: Competing and non-native standards require complex brokers or translation gateways.
Legacy Integration: Older industrial or environmental sensor networks lack modern web-scale APIs. [1, 2]
A site can have accurate sensors and still struggle to answer a simple operational question. The water meter reports one way, the temperature sensor another, and equipment status sits in a separate system. Bringing those readings together starts with understanding both their connections and their meaning.
Start with the decision
Suppose a facilities team wants to investigate unusual water consumption. Meter readings show the volume used. A pump status signal may help explain when equipment was running, while operating schedules provide context. Together, these can give the team a more useful basis for investigation.
The purpose is to make relevant information usable by the people responsible. Define that purpose before choosing how to connect the equipment.
A shared connection is only part of the answer
Interoperability means systems can exchange information and use it correctly. Receiving a number is not enough if the receiving system does not know what it measures.
A value of 25 could represent temperature, pressure or a counter. Even two temperature readings need consistent units. Device identity, location, measurement time and reading quality can be just as important as the value itself.
A practical integration therefore checks the complete path: the sensor interface, the communication method, the data format and the meaning assigned to the information.
Use the equipment that still serves you
Businesses often have useful equipment from several suppliers, installed at different times. A sensible connectivity project begins with an inventory of those assets and their available interfaces.
Some can provide information through a compatible connection. Others may require an adapter, configuration change or replacement. Understanding the actual equipment helps avoid unnecessary spending and identifies where integration work is needed.
Tigertek’s multi-protocol direction addresses the opportunity to connect compatible sensors and systems through an architecture suited to the application. Support for an individual device or protocol should be confirmed for the proposed installation.
Give the information a route
Tigertek combines local intelligence with mesh communications and encrypted data exchange. Mesh can provide a route between suitably placed nodes; it does not automatically translate every sensor protocol or make every device compatible.
That distinction matters. Carrying a message and interpreting its contents are separate jobs. A project needs both the appropriate interface and a planned communication network.
Internet access can remain optional for local operation. Information needed beyond the local network requires an appropriate external connection, planned around its recipients and access requirements.
Make a small integration prove its value
Begin with a few representative devices and one useful question. Check the source readings against the information received, including units, timestamps and behaviour when a device stops reporting.
Agree how missing or stale information will be identified. Confirm who may read the data and, separately, who may send commands where control is involved. Record the configuration so equipment can be maintained or replaced without losing its meaning.
This gives the organisation a concrete basis for expansion: a working connection, information that can be trusted and an operational benefit that can be assessed.
The Tigertek opportunity
For buildings, industry, water management and agriculture, Tigertek’s opportunity is to make compatible sensor information more accessible and useful through multi-protocol connectivity, local intelligence and mesh communications.
A successful project connects the right information to the right decision. It can also help organisations retain useful assets and develop their monitoring arrangements as needs change.
