Practical solutions built to make you more productive in the real world.
Arbiter Home Automation Platform
A-HAP v3.0.0 is a centralized platform for managing ESP32 and similar GPIO boards. It features embedded MQTT communication for instant output control, auto-generated board firmware, a configurable dashboard, sensor alerts, schedule sensor conditions, live sensor telemetry, video feeds, recording functions, and mobile app access. Simple to set up and available for Windows, Linux, Raspberry Pi, and macOS.
New in A-HAP v3.0.0
A-HAP v3.0.0 is a major architectural release. MQTT replaces HTTP polling for instant board communication, the server can generate and compile ESP32 firmware, and a configurable dashboard, sensor alerts, and schedule conditions expand the automation capability.
Embedded MQTT broker
A-HAP runs a built-in MQTT broker on port 1883. Boards connect at startup, publish heartbeats and telemetry, and receive output changes instantly via retained messages. LWT enables automatic offline detection.
Instant output control
Output changes from schedules, sensor triggers, the mobile app, or the web UI are pushed to boards immediately via MQTT. No poll delay. HTTP is now OTA-only.
Auto-generated ESP32 firmware
A-HAP generates and compiles board-specific Arduino sketches directly from the server, with WiFi credentials, MQTT config, sensor wiring, and output mapping pre-filled. OTA flash from the Board OTA page.
Sensor alerts
Define threshold-based alert rules on any sensor channel with configurable severity levels. Alerts fire and log events when conditions are met.
Schedule sensor conditions
Scheduled actions can now include sensor-based conditions — a scheduled output only fires if the sensor reading meets the defined condition at execution time.
Configurable dashboard
A new dashboard page displays live status widgets for boards, outputs, and sensors, giving a single-screen overview of the full automation system.
Board variants & LCD support
Hardware variants are now modelled with a seeder for common ESP32 boards. LCD display configuration is supported per board.
Expanded mobile app API
The mobile controller API now covers the full sensor, output, and board status feature set for the companion mobile app.
Core platform features
Role-based control
Manage unlimited custom automation roles, outputs, and schedules to automate a limitless number of devices from one platform.
Advanced Scheduling Engine
Create interval, recurring, and time-based automations with ease, including sensor-condition gating to control exactly when and how actions fire.
MQTT Communication
Embedded MQTT broker for instant push-based board control, heartbeat monitoring, and automatic offline detection via Last Will & Testament.
Sensor library and triggers
Use common sensors with A-HAP, then trigger outputs, fire sensor alerts, or apply schedule conditions from live channel readings.
Built-in Web Server
The machine you install A-HAP on automatically becomes the web server for the app and will be accessible over your local network.
