System Overview & Core Infrastructure

Local-First Platform Architecture

Built upon a robust, local-first Home Assistant deployment. All device communication, automation logic, and state evaluation execute entirely on on-premise hardware, guaranteeing privacy, zero cloud dependency, and instant response times even during internet outages.

AI-Assisted Integration (Model Context Protocol)

Connected via a Model Context Protocol (MCP) bridge that interfaces system telemetry directly with modern AI assistant tools. Enables automated health audits, intelligent energy trend analysis, and proactive system optimizations.

Secure Remote Connectivity & Networking

Zero-trust, encrypted remote access delivered without exposing inbound router ports. The underlying infrastructure is orchestrated through a managed software-defined network (SDN), paired with continuous external uptime monitoring for high availability.

Power Resilience & Telemetry

Integrated Uninterruptible Power Supply (UPS) system providing real-time load telemetry and battery health monitoring, with automated failover alerting and graceful system protections during power grid disruptions.

Solar Photovoltaic (PV) & Energy Management

Real-Time Inverter Telemetry

Solar inverter telemetry integrated locally to provide sub-second production updates across solar panel arrays, grid import/export flows, and electrical grid stability metrics without relying on third-party vendor clouds.

Solar Production & Battery Cycling

Continuous monitoring of solar generation, inverter operating temperatures, and battery charge/discharge cycles to ensure peak operating efficiency across seasonal changes.

Unified Energy Dashboard & Sub-Metering

A centralized energy dashboard dynamically tracks total solar generation, self-consumption rates, and grid exchange. High-consumption household circuits—including EV charging, climate control, and water heating—are sub-metered to provide clear visibility into household power distribution and cost savings.

Multi-Vehicle Dynamic EV Charging Engine

Standards-Based Smart Charger (OCPP)

Universal smart EV charger integrated locally using open charging protocols (OCPP), providing precise control over charge rates, session scheduling, and electrical current modulation.

Decoupled Multi-Vehicle Intelligence

An intelligent vehicle profile engine dynamically configures charge parameters based on the active vehicle connected, automatically tailoring battery capacity targets, vehicle charging efficiency, and desired driving range across multiple household EVs.

Real-Time Session Calculations

Dynamic algorithms calculate instantaneous charging power, total kilowatt-hours delivered, percentage battery gained, and driving kilometers added in real time throughout every charging session.

Isolated Vehicle Billing & Cost Tracking

Automated energy metering separates consumption for each household vehicle across daily and monthly cycles, providing exact accounting of charging costs and grid versus solar energy contribution.

Solar Soak Automation & Hardware Protection

An automated load-following charging engine modulates charging speeds in real time to absorb excess rooftop solar power. The algorithm incorporates smooth rate-stepping and cooldown hysteresis to protect vehicle onboard chargers and electrical hardware from rapid cycling.

Actionable Plug-in Notifications

When an EV cable is plugged in, an actionable notification is dispatched to mobile devices allowing 1-tap confirmation or vehicle profile switching before charging begins.

Environmental Sensing, Mesh Networking & Security

High-Capacity Dual Mesh Network

A dual-coordinator Zigbee wireless mesh network provides whole-home coverage and sensor redundancy, isolating high-frequency environmental sensors from security circuits to maximize reliability without congesting home Wi-Fi.

Comprehensive Environmental Telemetry

An array of unobtrusive wireless sensors monitors ambient temperature, relative humidity, light levels, and entry points across living areas, workshops, and outdoor spaces.

Integrated Security & Surveillance

A hardwired perimeter security alarm system is bridged for real-time zone monitoring and instant intrusion alerts, complemented by local IP surveillance cameras for on-premises event verification and perimeter awareness.

5

Lighting & Switching Automation

In-Wall Smart Switching

Smart relays installed behind physical wall switches maintain traditional tactile switch operation during network downtime while enabling scheduled scenes, presence automation, and remote control.

Adaptive & Ambient Lighting

Smart LED downlights and custom addressable accent lighting controllers deliver subtle ambient lighting and circadian transitions that automatically adjust colour temperature to natural daylight cycles.

Intelligent Load Automation

Smart energy-monitoring plugs manage dedicated appliances and workshop equipment power rails, featuring automated idle shutoff for safety and energy conservation.

AI-Assisted Maintenance & System Hygiene

Automated System Audits

Scheduled AI-assisted health audits evaluate device connectivity, identify anomalies in telemetry feeds, and verify mesh communication routes across the smart home network.

Proactive Battery Management

Automated threshold monitoring tracks wireless sensor battery levels, generating advance notifications for replacements before sensors drop offline.

Continuous Performance Optimization

Routine automated health sweeps identify and clean up stale data and unreachable devices, minimizing database overhead and maintaining lightning-fast dashboard responsiveness.

7

Control Interfaces & Command Bridges

Actionable Mobile Alerts

Rich, interactive push notifications sent to mobile devices for perimeter alerts, power failure events, and EV charging milestones, allowing instant one-tap responses.

Secure Chat & Voice Bridges

Custom Discord and Telegram control bots enable authenticated remote status queries, system commands, and alerts without exposing administrative web interfaces.
