The Internet of Things (IoT) is revolutionizing modern agriculture, creating a vast and interconnected ecosystem where every device — from smart irrigation valves and soil moisture sensors to weather stations, drones, water pumps, and autonomous farming machinery — can communicate seamlessly over the network. In the agrotech industry, the ability to integrate devices across different platforms is not just a convenience — it is a competitive necessity.
For most farmers, the simplest approach is to purchase smart irrigation devices directly from the manufacturer and use the manufacturer's own IoT platform for remote monitoring and control. This plug-and-play model works well for end users who want a hassle-free experience. Check out our guide: What Is a Smart Irrigation Valve? for a deeper understanding of the technology. However, the landscape becomes more complex when agrotech companies or technology service providers — who already operate their own IoT platform or farm management system — want to integrate QOTO's intelligent irrigation valves into their existing infrastructure. Is that possible? Absolutely, YES.
QOTO has developed a comprehensive set of flexible and mature protocol alignment solutions designed specifically for these integration scenarios. Whether you are a farmer looking for a turnkey solution, or a technology company seeking to embed QOTO's hardware into your own ecosystem, QOTO has a solution that fits. In this article, we will walk through the invisible wireless networks behind QOTO's smart irrigation system and demonstrate exactly how each integration scenario works — covering both 4G (Cellular) networks and LoRaWAN networks.
4G LTE is the backbone of QOTO's smart irrigation valve connectivity. With widespread cellular coverage, low latency, and high data throughput, 4G-enabled valves are ideal for precision irrigation applications where real-time control and feedback are critical. QOTO's 4G valves — such as the QT-01EF Solar Smart Valve and QT-12 Series — support MQTT protocol, HTTP/HTTPS API, and direct cloud-to-cloud communication, offering three distinct integration paths.
This is the most common integration scenario for agrotech companies and IoT platform providers. In this model, the customer already has a robust IoT platform and wants to add QOTO's 4G smart irrigation valves to their hardware portfolio. Instead of building new hardware from scratch, the customer simply integrates QOTO's valves at the protocol level.
How it works: QOTO's 4G valve communicates with the customer's MQTT broker (server) over the cellular network. The valve publishes telemetry data — such as valve status, flow rate, battery level, signal strength, and solar panel voltage — to designated MQTT topics. The customer's platform subscribes to these topics to receive real-time data. Conversely, the customer's platform publishes control commands (open/close, scheduled irrigation, flow adjustment) to command topics, which the valve subscribes to and executes.

Key benefits:
Zero hardware development — the customer leverages QOTO's proven valve hardware and focuses on software and service delivery
Full brand control — the customer delivers irrigation services to their end users under their own brand, through their own platform
Standard MQTT protocol — widely adopted in IoT, easy to integrate, supports QoS levels for reliable message delivery
Scalable architecture — MQTT's publish/subscribe model naturally supports thousands of devices
Typical users: IoT platform companies, agrotech startups, large agricultural enterprises with in-house software teams, system integrators.
This scenario is designed for farmers and agricultural end users who want a ready-to-use smart irrigation solution without any technical integration work. It is the simplest and fastest way to get started with remote irrigation control.
How it works: The farmer purchases QOTO's 4G smart irrigation valves — such as the QT-01EF Solar Smart Valve or QT-12 Series — inserts a standard SIM card into each valve, and the valves automatically connect to QOTO's cloud-based IoT platform. Through QOTO's mobile app or web dashboard, the farmer can remotely monitor and control every valve — open or close irrigation zones, set scheduled irrigation plans, view historical data, and receive real-time alerts for anomalies.

Key benefits:
Plug and play — no servers, no coding, no IT infrastructure required
Low upfront cost — only pay for the hardware; the platform is included
User-friendly interface — designed for farmers, not engineers
Remote management — control irrigation from anywhere with cellular coverage
Typical users: Individual farmers, farming cooperatives, plantation managers, greenhouse operators.
For technology companies that want a faster and simpler integration path than full MQTT alignment, this cloud-to-cloud API integration is the ideal solution. Instead of managing device-level protocols, the customer integrates at the server level using standard HTTPS RESTful APIs. The QT-02 LoRa Smart Valve Controller is a popular choice for this integration model, offering both 4G and LoRa connectivity in a single unit.
How it works: QOTO's 4G valves connect to QOTO's cloud platform as normal. The customer's servers communicate with QOTO's servers via secure HTTPS API calls. The customer's platform can query device status, retrieve historical data, and send control commands through QOTO's API endpoints. In this architecture, the valves are effectively controlled by two clouds working in tandem — QOTO's platform handles device communication and data persistence, while the customer's platform handles business logic, user management, and service delivery.

Typical users: Agtech SaaS platforms, farm management software providers, companies with existing cloud infrastructure.
LoRaWAN (Long Range Wide Area Network) is a low-power, long-range wireless protocol that is particularly well-suited for agricultural IoT applications. Unlike 4G, which relies on cellular carrier infrastructure, LoRaWAN operates in unlicensed ISM frequency bands (such as 868 MHz in Europe, 915 MHz in North America, and 470 MHz in China), allowing customers to deploy their own private LoRaWAN gateways and build a completely independent wireless sensor network. QOTO's LoRaWAN smart irrigation valves — such as the QT-25ZF LoRaWAN Smart Irrigation Valve — are designed to seamlessly integrate into any standard LoRaWAN network infrastructure. Learn more in our deep dive: LoRaWAN Smart Irrigation Valve for Remote Farmland.
Many agrotech companies and smart farm operators have already deployed their own LoRaWAN gateways and Network Server (LNS) infrastructure. In this scenario, QOTO provides LoRaWAN-enabled irrigation valves like the QT-25ZF Series that can be directly onboarded to the customer's existing network.
How it works: QOTO's LoRaWAN valve is pre-configured with standard LoRaWAN OTAA (Over-The-Air Activation) or ABP (Activation By Personalization) credentials. The customer simply registers the valve on their LoRaWAN Network Server using the device's unique DevEUI, AppEUI, and AppKey. Once registered, the valve transmits sensor data and receives control commands through the customer's own LoRaWAN infrastructure — no cellular subscription, no third-party cloud dependency.

Key benefits:
Full network ownership — the customer operates and controls their entire LoRaWAN infrastructure
Zero recurring connectivity costs — no SIM cards, no cellular data plans
Ultra-low power consumption — LoRaWAN valves can operate for years on battery or solar power
Long-range coverage — a single LoRaWAN gateway can cover up to 10-15 km in rural areas
Standard LoRaWAN compliance — compatible with any LoRaWAN v1.0.x network server (ChirpStack, The Things Network, Actility, etc.)
Typical users: Large farms with existing LoRaWAN infrastructure, agrotech companies operating private networks, research institutions, smart agriculture solution providers.
This scenario is a hybrid approach for customers who want the benefits of LoRaWAN connectivity combined with the simplicity of cloud-based management. QOTO provides both the LoRaWAN smart irrigation valves — including the QT-25ZF Series and QT-02 Series — and the cloud platform, while the customer's system connects to QOTO's platform via API for data exchange and control.
How it works: The customer deploys QOTO's LoRaWAN valves and gateways in the field. The valves communicate with the gateways, which forward data to QOTO's LoRaWAN Network Server and Application Server in the cloud. The customer's platform — whether a farm management system, ERP, or custom dashboard — integrates with QOTO's cloud via RESTful API to retrieve real-time valve data, historical records, and to send control commands. This is the LoRaWAN equivalent of 4G Scenario 3, offering the same cloud-to-cloud integration benefits with the added advantage of LoRaWAN's low-power, long-range characteristics.

Rapid deployment — QOTO handles the LoRaWAN infrastructure; the customer focuses on their application layer
API-first design — well-documented RESTful APIs for seamless integration
Flexible data flow — pull data on demand, set up webhooks for real-time events, or batch export for analytics
Typical users: Agtech companies wanting LoRaWAN hardware without building their own network server, system integrators, farm management platforms.
For farmers and agricultural enterprises who want a complete, out-of-the-box LoRaWAN smart irrigation system, QOTO provides the full stack — LoRaWAN valves (QT-25ZF), LoRaWAN gateways, cloud platform, and mobile/web application. This is the LoRaWAN equivalent of 4G Scenario 2, offering the same turnkey experience with the unique advantages of LoRaWAN technology.
How it works: The farmer purchases a complete QOTO LoRaWAN kit — valves for each irrigation zone, one or more gateways depending on farm size and topography, and access to QOTO's cloud platform. After simple on-site installation, the system auto-configures and the farmer can immediately start remote irrigation management through QOTO's app. No cellular subscriptions, no complex IT setup — just reliable, long-range smart irrigation control.
