Building Self-Sufficiency System with Home Assistant

Hello! I’m bunkergardenlabs, working on building a self-sufficiency system with Home Assistant.

Project Overview: I’m working on a project that aims for complete self-sufficient living based on solar power, with all systems integrated and controlled through Home Assistant.

Current Progress:

Phase 1: Converted refrigerator → Smart plant growing chamber (ESPHome + relay control)

Phase 2: Home Assistant API → TouchDesigner real-time integration success! Implemented visualization where sensor data transforms into colors and shapes

Final Goal: Complete independent living with solar power + plant cultivation + water purification systems

:clapper: Process Documentation: I’m recording this entire process as a documentary film series. This is not a step-by-step tutorial!

:floppy_disk: For those who might need it, I’ll share the TouchDesigner API integration code!
