Tuct - esphome stuff

This is a collection of esphome projects and components that i build over the years.

Mostly DIY esphome devices, but also some some components and esphome based custom firmware

ESPHome Components

• Levoit – Generic Levoit ESPHome component supporting Core (200/300/400) and Vital (100/200) series with UART communication, filter tracking, and multi-entity support
• Sensirion Sen66 – Integration for the Sensirion Sen66 air quality sensor
• Levoit Core300s – DEPRECATED (use generic Levoit component instead)
• Levoit Core400s – DEPRECATED (use generic Levoit component instead)

Project - Free Levoit Air Purifiers

Collection of custom ESPHome firmware and hardware projects for Levoit air purifiers, eliminating cloud dependency and enabling native Home Assistant integration.

Supported Models:

• Core 300S – Custom firmware (no hardware modifications needed)
• Core 400S – Custom firmware (no hardware modifications needed)
• Vital 100S – Custom firmware (no hardware modifications needed)
• LV-PUR 131S – Custom firmware + ESP32-C3 MCU upgrade + PM5003 sensor upgrade (hardware hack; plays Doom!)
• Mini – Custom PCB, 3D-printed parts, and firmware (fully reversible modification)

Key Features Across All Models:

• Full Home Assistant integration via native ESPHome API (no cloud required)
• Fan control with Manual, Auto, and Sleep modes
• CADR-based filter lifetime tracking with configurable replacement intervals
• Filter low threshold binary sensor and one-touch reset button
• Real-time air quality and PM2.5 monitoring
• Display control and WiFi LED management

Getting Started:

See Free Levoit Project Documentation for complete details including:

• Installation Methods – 3 hardware approaches (reuse original ESP, dual ESP with switch, replace module)
• UART Protocol Reference – Frame format, checksums, TLV encoding for Vital series, command/response structures
• Model-Specific Guides – Disassembly, flash procedures, Quick Facts (MCU versions, speeds, CADR ratings) for each model
• Component Integration – Entity types, filter tracking calculations, configuration examples

Community Resources:

• Vital 200S/Pro ESPHome – Extended Vital series support
• Core 300S Alternative – Community project
• ESPHome Levoit Integration – Reference implementation

Other Projects

• aqMood – Emotionally responsive air quality mood light with Sen66 sensor integration (custom PCB, 3D parts)
• Smart Control for Prusa Enclosure – Enclosure climate monitoring and control (ESPHome, 3D parts)
• Tiny Wash & Cure – 3D printer support device control (custom PCB)
• Automated Iris – Automated aperture/iris control (ESPHome, 3D parts)

TODO

• Add README to tiny-wash-and-cure project
• Add README to automated-iris project
• Expand aqMood documentation for wall-mounted variants
