RuView is a WiFi sensing platform that uses ESP32 hardware and a stack of AI models — spiking neural networks, graph neural networks, and temporal convolutional networks — to detect human presence, estimate 17-point body pose, and monitor vitals like breathing rate and heart rate. All of this happens without any cameras, through walls, in complete darkness, using only WiFi Channel State Information (CSI). The system achieves 92.9% PCK@20 accuracy for pose estimation and runs on ~$9 of ESP32-S3 hardware, with a Python backend handling the heavier model inference. It can track multiple people simultaneously, detect falls, and monitor respiratory rates in real time. MIT licensed and fully open source. Camera-free sensing that works through walls at $9 in hardware is a genuine privacy-preserving alternative to video surveillance for use cases like elder care monitoring, security, and occupancy sensing. The limitation is that it still requires a Python inference server for the heavier models — the ESP32 handles data capture and lightweight preprocessing only.

Stash is an open-source persistent memory infrastructure for AI agents built on PostgreSQL and pgvector. Unlike retrieval-augmented generation, which searches static documents, Stash actively learns from agent experience — consolidating raw observations into facts, relationships, causal links, and higher-order patterns over time. The system exposes 28 MCP tools covering the full cognitive stack: episode storage, fact synthesis, entity graph management, goal tracking, failure pattern recognition, and self-correction when contradictions emerge. It deploys via Docker Compose in three steps and works with any OpenAI-compatible API — Claude, GPT, local models via Ollama. Hierarchical namespaces let agents keep user facts separate from project facts separate from self-knowledge. This fills a real gap in the agent ecosystem. Most agent frameworks treat each session as stateless, which means agents repeat the same mistakes and lose hard-won context. Stash gives agents a persistent cognitive layer that compounds. It surfaced on Hacker News this week to notable developer interest and is worth watching as MCP adoption accelerates.
Reviewer scorecard
“ESP32 at $9 for the capture layer with Python handling inference is a sensible hardware/software split. The multi-person tracking and fall detection make this immediately deployable for elder care or smart building occupancy. I'd want to see benchmark numbers across different home layouts and WiFi router brands before shipping it in a product, but the architecture is sound.”
“The 28 MCP tools are the right abstraction level — my Claude Desktop agents can now actually remember what I've told them across sessions without me writing my own memory layer. The Docker Compose setup is clean and the pgvector backend is production-ready.”
“92.9% PCK@20 sounds impressive until you realize PCK@20 is a fairly lenient threshold — this is demo-quality, not production-quality pose estimation. RF-based sensing is notoriously environment-specific; move the router six inches and retrain. The 'through walls' framing also raises real privacy concerns: this can monitor people without their knowledge or consent.”
“The consolidation pipeline sounds elegant in theory but in practice you're letting an LLM synthesize 'causal links' and 'higher-order patterns' from raw observations. That's a recipe for hallucinated beliefs that compound over time. I'd want rigorous testing before trusting this in any production agent.”
“Camera-free sensing is foundational infrastructure for a world where AI monitors physical spaces without the privacy baggage of video. Elder care, physical rehabilitation, smart home automation — all of these become viable in privacy-sensitive contexts once you remove the camera. At $9 per node, mass deployment is economically possible for the first time.”
“Persistent memory is the missing piece between 'AI assistant' and 'AI colleague.' Stash's self-correction and failure pattern recognition are early implementations of what agents will need to become genuinely reliable over long time horizons.”
“Body pose tracking without cameras opens creative possibilities that were previously gated by camera placement and lighting — interactive installations that work in the dark, through partitions, or in spaces where cameras aren't appropriate. The human presence detection alone is useful for responsive environments that need to know when people enter a space without watching them.”
“Finally an agent that remembers my brand guidelines, tone preferences, and past feedback without me repeating myself every session. The namespace hierarchy means I can have separate memories for different clients.”
