Humid1-OS: Ecosystem & Cloud Infrastructure

---

Warning

Project Under Construction: The HUMID1-OS repository and its associated cloud and hardware integration are currently under active development. Features, code structures, and documentation are subject to change.

Note

Professional Scope: Designed by Humiditron, the HUMID1-OS architecture is engineered to demonstrate production-grade IoT competencies, bridging low-level embedded systems with modern cloud-native server administration. It serves as a comprehensive portfolio piece highlighting full-stack ownership—from bare-metal microcontroller firmware to secure cloud orchestration and zero-touch OTA pipelines.

1. Project Overview & Ecosystem Scope

HUMID1-OS is a community-driven, open-source, IoT-enabled humidor monitoring ecosystem built for precise, low-maintenance environmental control.

• Author: Humiditron (also heard as HYOO-mi-DEE-tron)
• Ecosystem Domain: Humid1.com
• Backend Infrastructure: ThingsBoard IoT server.
• Core Strategy: Standardizing on a single, off-the-shelf hardware target to eliminate fragmentation, supply chain overhead, and custom debugging complexity. Devices are flashed once during setup, with subsequent configuration and lifecycle updates handled seamlessly Over-The-Air (OTA) via ThingsBoard.
• Future Vision: Opening up the platform for public use as a free service supporting standard hardware.

Core Engineering Pillars

• Embedded Firmware & Hardware Integration: Direct peripheral management on the ESP32-S3 architecture, handling power profiles, I2C sensor polling (SHTC3), real-time clock synchronization, and low-power e-Paper display rendering.
• Cloud Infrastructure & DevOps: End-to-end self-hosting implementation utilizing ThingsBoard as the IoT backend, orchestrated via Docker, secured behind a reverse proxy on a dedicated VPS.
• Zero-Touch Maintainability: Design focus on lifecycle management, utilizing automated Over-The-Air (OTA) deployment strategies and Bluetooth-based provisioning to eliminate friction post-deployment.

2. Hardware Target & Technical Specifications

HUMID1-OS standardizes on the Waveshare ESP32-S3-ePaper-1.54G (V2 hardware platform) SKU:32298, featuring integrated low-power peripherals tailored for sealed environment monitoring.

Hardware Specifications (V2 Board)

• Microcontroller: ESP32-S3-PICO-1-N8R8 SoC (Xtensa 32-bit LX7 dual-core processor operating up to 240MHz, with integrated 8MB Flash and 8MB PSRAM in a stacked package).
• Display: 1.54-inch 2-color BW (Black, White) e-Paper panel with a 200x200 resolution, offering ultra-low power consumption and sunlight readability.
• Environmental Sensor: Onboard SHTC3 temperature and humidity sensor connected via shared I2C (GPIO47/48, address 0x70).
• Real-Time Clock (RTC): Onboard PCF85063 RTC chip for precise time management.
• Audio Codec: Low-power ES8311 audio codec chip with microphone and speaker support.
• Storage: TF card slot (must be formatted as FAT32).

Critical Board-Specific Power & GPIO Wiring

To ensure proper operation under deep-sleep states, the firmware accounts for specific hardware circuit requirements:

• Battery Power Latch (GPIO17): Must be driven HIGH during boot and frozen via deep-sleep pin holds to maintain the power latch when the physical power button is released.
• Panel Power (GPIO6): Inverted power rail where LOW enables power to the e-Paper panel and HIGH powers it down during sleep to eliminate idle draw while preserving the image on screen.
• Wake Pin (GPIO18): Connected to the physical PWR button (active-low with pull-up) to allow on-demand wake cycles.

3. Firmware Architecture, Provisioning & Power Management

The firmware operates on an optimized Wake-Read-Refresh-Sleep duty cycle designed to maximize battery longevity on portable deployments.

• Duty Cycle: Wakes up at defined intervals (e.g., every 30 minutes) to poll sensors, update the display once, sync time via SNTP, and return to deep sleep.
• Device Provisioning: Utilizes Bluetooth Low Energy (BLE) for seamless, secure initial device provisioning and Wi-Fi credential setup, eliminating cumbersome AP configuration modes.
• UI Design Constraints: Built using LVGL with strict adherence to 2-color palettes (Black, White), opaque fills (bg_opa: COVER), disabled animations (animated: false), and idle update restrictions to prevent unnecessary full-panel e-Paper refreshes.

---

4. Cloud Infrastructure & DevOps

• IoT Backend: ThingsBoard handles device telemetry ingestion, client attribute management, and dashboard visualization.
• Deployment & Provisioning: Containerized via Docker on a rented VPS, ensuring strict data privacy and isolated network orchestration.
• OTA Pipelines: Integrated ThingsBoard OTA mechanisms push incremental firmware updates during scheduled or triggered wake windows.

---

5. Commercialization & Open-Source Strategy

While initial explorations considered monetizing the product, a thorough cost-benefit analysis revealed major structural hurdles:

• Regulatory & Compliance Costs: Expenses associated with FCC regulatory testing.
• Supply Chain & Logistics: Overhead tied to physical stock storage, warehousing, and managing third-party distributors.
• Customer Operations: Long-term support burdens for a consumer customer base and processing product returns.

Quote, Status:Pending

I'm still waiting on sales to get back with me about turn-key 'white goods' development, I assume they are either busy, or not interested in supplying an unofficial/official quote.

(I have both hope and patience)

The Pivot: Rather than pursuing a commercial product path, the project's optimal future is fully open source. By anchoring the ecosystem around reliable, affordable, off-the-shelf hardware, HUMID1-OS eliminates hardware manufacturing risk while maximizing community accessibility, customization, and collaborative growth.
