## Introducing Ruammitr **An edge computing kiosk for smart farms — built to run offline, engineered to think ahead.** The Ruammitr is a rugged edge-computing kiosk designed for the realities of the field. When the internet drops, it keeps making the right calls. When you're back online, it unlocks a deeper kind of intelligence. One device, two modes of control — traditional reliability today, predictive optimization tomorrow.  ## Always On, Even When Offline Connectivity in agriculture is unreliable, and a lost signal shouldn't mean a lost crop. The Smart Farm Controller runs **rule-based control** directly on the edge — no cloud, no internet, no problem. - **Zero downtime** — Control logic lives on the device, so it never waits on a network round-trip. - **Predictable and safe** — Battle-tested, deterministic rules you can read, audit, and trust. - **Works anywhere** — Remote fields, off-grid sites, and weak-signal environments are not afterthoughts. This is the reliability operators already expect. It's the floor — not the ceiling. ## When Connected: Model-Predictive Control with a Digital Twin Here's where it gets interesting. Once the controller is connected to Yiem's cloud, it gains access to a **Digital Twin** of your farm system and switches into **Model-Predictive Control (MPC)** — and this is where we believe the real value is unlocked. Where rule-based control reacts to what's happening *right now*, MPC *predicts what will happen* and acts proactively. It continuously simulates your system against a live model, evaluates a horizon of possible futures, and chooses the actions that optimize for your goals — yield, resource use, energy, cost — before conditions demand it. ## Why MPC Out-Performs Traditional Rule-Based Control This is our innovation, and it's the difference between maintaining a process and continuously improving it. 1. **Proactive, not just reactive.** Rules fire *after* a threshold is crossed. MPC anticipates change and acts in advance — adjusting before a problem develops rather than correcting after it. 1. **Optimization across competing goals.** Traditional rules handle one variable at a time. MPC weighs multiple objectives simultaneously — water, nutrients, energy, throughput — and finds the balance rules can't. 1. **Handles complexity and delays.** Real farm systems have lag, nonlinearity, and interacting parts. MPC models those dynamics explicitly, so it controls the system as it truly behaves, not as a simplified rule assumes. 1. **Fewer wasted inputs.** By predicting demand and avoiding over-correction, MPC reduces waste — water, fertilizer, energy — while holding or improving output. 1. **Continuously improving.** The Digital Twin stays connected to your data, so the model refines itself over time. The controller gets smarter as your farm operates — rules stay fixed forever. 1. **Resilient intelligence.** The best of both worlds: on the edge, it falls back to rock-solid rule-based control offline; online, it layers predictive optimization on top. You never lose control, and you always get the smarter mode when it's available. ## One Platform, Two Modes, Zero Compromise | | Rule-Based (Edge / Offline) | Model-Predictive (Cloud / Digital Twin) | | --- | --- | --- | | **When it runs** | Always, offline-first | When connected to Yiem cloud | | **How it decides** | Reactive, threshold-based | Predictive, optimization-based | | **Goals** | Single-variable stability | Multi-objective optimization | | **Adapts over time** | No | Yes — via the Digital Twin | The Smart Farm Controller gives you reliability today and a path to optimization tomorrow — no rip-and-replace, no all-or-nothing. ## Built for the Field Rugged edge hardware, designed to withstand the conditions farms actually operate in. Deploy it anywhere, connect it when you can, and let intelligence scale with your connectivity. --- *This is an early-stage product launch. Availability, pricing, and partnership details coming soon.*

## Introducing Yiem Inc **Technology that multiplies every industry.** Yiem is a holding and technology company. We don't just invest in growth businesses — we engineer them. Across our verticals, a single modular platform of AIoT, data, connectivity, and thoughtful design does the heavy lifting, letting us build and operate alongside the businesses we touch. ## One Platform, Three Sectors The same core technology stacks onto different industries, each running as its own standalone experience: - **AIoT & Smart Systems** — Connected intelligence for factories, farms, energy, and facilities. Sensors, data, and control in one platform. - **Water & Sustainability** — Intelligent wastewater management: treatment, compliance, and resource recovery driven by real-time data. - **Premium Distribution** — Curated wines and heritage, delivered to connoisseurs and professionals, from vineyard to table. ## Why Yiem - **Built to scale.** One platform across every vertical means proven patterns, not untested guesses, wherever we go. - **Sector expertise.** Manufacturing, water, and premium goods — deep domain knowledge where it matters. - **Data-driven growth.** Real-time data isn't a feature, it's the foundation. - **Aligned, long-term partner.** We build and operate alongside the businesses we touch. ## From One Engineer to Three Industries Yiem started with one AIoT engineer and a conviction: the same technology that connects a factory can connect a vineyard, a treatment plant, and everything in between. Today that conviction runs through three verticals — and we're just getting started. --- *Note: Scale figures and the News section referenced on the site are placeholder content and should not be quoted as fact at launch.*

## Yiem Raises Seed Funding from Expresso, a PTT Group Subsidiary **Yiem is proud to announce a seed investment from Expresso, a subsidiary of PTT Public Company Limited — Thailand's national energy champion.** This seed round of 1 million baht affirms what we've been building: smart, offline-first intelligence for the facilities, farms, and industries that keep our country running.

## Introducing Kathi **One small box. Temperature, humidity, and illumination — all in one, all wireless.** Kathi is a compact environmental sensor designed to pair seamlessly with the Yiem Smart Farm Controller. It measures three of the most important growing conditions in a single, unobtrusive device — and sends the data straight to your controller, wirelessly. ## What Kathi Measures - **Temperature** — Keep an eye on the conditions your crops, livestock, or stored goods need. - **Humidity** — Monitor moisture in the air to catch problems before they spread. - **Illumination** — Track light levels, whether for growing spaces or light-sensitive environments. Three sensors, one box, one connection. No tangled wiring, no complex setup. ## Wireless to Your Controller Kathi transmits its readings directly to your Yiem Smart Farm Controller — no cables, no fuss. It slots into your existing setup as another node in the network, feeding real-time data into the control logic so both rule-based and Model-Predictive modes have fresh inputs to work with. ## Read It at a Glance Kathi has a built-in mini LCD display that shows its current readings at a glance — temperature, humidity, and illumination right on the device. No app, no phone, no controller screen required to get an instant read on the environment around you. ## A Trusted Cross-Check Beyond the quick glance, Kathi is a reliable cross-check. Use it to verify what your controller is reporting, sanity-check sensor data in the field, or spot discrepancies before they turn into decisions. It's the second pair of eyes on your environment — always there, always accurate. ## Built to Fit the Field Small enough to place anywhere you need to watch the environment. Simple enough to trust without a manual. Designed to work as part of the Yiem ecosystem, not against it. ## Pair It With Your Controller Kathi feeds clean, wireless environmental data into your Yiem Smart Farm Controller — the same data that powers offline rule-based control and, when connected, Model-Predictive Control with a Digital Twin. More inputs means smarter decisions, whether you're offline or online. --- *This is an early-stage product launch. Availability, pricing, and pairing details coming soon.*
