|
|
|
|
**Project:** Smart Home + Local LLM + Hybrid AI Bridge

|
|
**Created:** 2026-02-09
|
|

## Project Overview
|
|
|
|
Privacy-first smart home system using Home Assistant Yellow with local voice control, a dedicated local LLM server, and a hybrid routing bridge that keeps private data local while leveraging Claude and Grok APIs for tasks requiring external search or heavy reasoning.
|
|
|
|
## Design Goals
|
|
|
|
1. No Google/Alexa dependency -- fully local voice control
|
|
2. Local LLM for private queries (home automation, sensor data, cameras)
|
|
3. Hybrid bridge to Claude API (reasoning) and Grok API (internet search)
|
|
4. Privacy-first: private data never leaves the network
|
|
5. Network segmentation (VLANs) for IoT isolation
|
|
6. Integration with Victron solar system (future crossover with wrightstown-solar project)
|
|
|

## Crossover with Wrightstown Solar
|
|
|
|
When the Victron MultiPlus II + Cerbo GX are installed:
|
|
- Modbus TCP integration from Cerbo into Home Assistant
|
|
- Energy dashboard with solar production + battery SOC
|
|
- Solar-aware automations ("run dishwasher when battery > 80%")
|
|
- LLM-powered energy analysis ("analyze my usage trends this week")
|
|
- See: `projects/wrightstown-solar/` for full solar system design
