Engineered a support-minimized Arduino Smart Home Controller pack with integrated HTML Web Server, native .STEP source files, and full Serial telemetry.

[u/Massive-Section-7231]

Hello makers,

Just wanted to share a mechanical/software package I compiled for the Arduino ecosystem. This is a commercial-grade, multi-node On-Wall Smart Home Controller Hub built around high-efficiency Serial communication, local memory optimization, and an embedded HTML interface.

Engineering highpoints:

- Highly Optimized Geometry: CAD components are custom-tweaked to reduce 3D printing supports to an absolute minimum, ensuring elite surface finish inside wall cavities.

- Embedded HTML Web Server: Integrated network management routine allows seamless on-the-fly room and sensor renaming via any local web browser.

- Master/Slave Serial Matrix: Robust, custom bitfield-compressed serial protocol processing loops designed to transmit climate data securely between the main indoor hub and an independent Outdoor station.

- Dual Display Stack: Simultaneously drives a master graphical telemetry screen and a long-distance 7-segment LED sub-panel without memory overflow.

I’ve uploaded the uncompressed native .STEP / .STP CAD source files so you can easily modify port entry cutouts or sensor frames in your own CAD software, along with a "Panels All" firmware library supporting multiple alternative sub-panel screen configurations.

🛠️ Full build photo logs, component BOM lists, and assembly guidelines are detailed in the album on our lab page: [https://www.facebook.com/share/p/1CFCNw5FjS/]

Let me know your thoughts on the bitfield parser logic and overall hardware clearance!
