NestPulse

Inspiration

I wanted my UGREEN AI NAS to become more than a place to store files and camera footage. I wanted a private, always-on companion that could help me understand what happened at home, notice events that may need attention, and follow my pet’s day without sending sensitive household data to the cloud.

I was inspired by two everyday problems: security footage can create hours of unclear recordings, and pet owners often wonder what their pet did while they were away. Instead of scrolling through clips or relying on generic cloud notifications, I wanted a single local assistant that could turn scattered events into clear, useful answers.

NestPulse was born from a simple question: What if my NAS could help me protect my home and understand my pet—privately?

What it does

NestPulse is a privacy-first AI Skill for UGREEN AI NAS that turns home events and pet activity into clear, actionable summaries.

With Home Safety, I can ask:

“Is everything okay at home?”

NestPulse reviews approved NAS footage, event logs, and household notes to create a concise security brief. It can highlight deliveries, motion near entry points, unusual activity, and events that may need review. It separates observed facts from possible interpretations, so a motion event is described as needing review rather than being automatically labeled as an intrusion.

With Pet Watch, I can ask:

“What did my pet do today?”

NestPulse searches relevant clips and event records to create a daily pet recap. It can identify key moments, describe general activity patterns, link to the most relevant footage, and provide an optional narration of the day. For example, it may summarize periods of rest, play, movement near a door, barking, or unusual inactivity.

NestPulse can:

• Create a daily or on-demand home brief.
• Summarize security-related events into short, understandable updates.
• Classify events as informational, needing attention, or urgent.
• Retrieve relevant footage using timestamps and event context.
• Create a pet activity timeline and daily recap.
• Provide an optional narrated pet-day summary.
• Flag possible patterns for review, such as repeated barking, unusual inactivity, or movement near an exit.
• Keep sensitive footage and household context local on the NAS wherever possible.

How we built it

I designed NestPulse as a privacy-first Skill for the UGREEN AI NAS ecosystem.

The project uses:

• UGREEN AI NAS as the local, always-on household hub.
• UGOS as the NAS operating environment.
• Uliya and the UGREEN Skill Developer Package to define the Skill’s workflow and capabilities.
• SKILL.md to describe the Skill’s purpose, inputs, permissions, workflow, and output format.
• Markdown reference files for the home-brief template, pet-recap template, event classification rules, safety guidance, and test cases.
• Local AI processing to analyze approved NAS files and generate understandable summaries and recommendations.

The workflow follows four steps:

1. Collect context — NestPulse accesses only user-approved folders, camera-event sources, and household notes on the NAS.
2. Understand events — The Skill extracts relevant details from event logs, timestamps, camera-related metadata, and user-provided descriptions.
3. Assess importance — It groups events into home-safety and pet-activity categories, then assigns an urgency level.
4. Communicate clearly — It produces a concise brief with findings, source-linked clips, recommended actions, and uncertainty flags.

The urgency model is intentionally simple:

[ \text{Priority} = f(\text{event type}, \text{time}, \text{location}, \text{confidence}, \text{user-defined rules}) ]

For example, a daytime motion event at the front door may be informational, while unexpected motion near an entry point late at night can be marked as needing attention. Likewise, normal pet activity may be part of the daily recap, while repeated distress-like behavior or unusual inactivity can be flagged for review.

NestPulse does not pretend to know everything. When information is missing, unclear, or conflicting, it states its uncertainty and asks for confirmation instead of inventing a conclusion.

Challenges we ran into

The biggest challenge was balancing usefulness with responsibility.

Home security and pet wellbeing are high-stakes topics. A false alarm can create unnecessary anxiety, while a missed warning can create a false sense of safety. I therefore designed NestPulse to avoid absolute claims such as “an intruder was detected” or “my pet is sick” unless the evidence clearly supports them.

Other challenges included:

• Ambiguous events: A motion event can mean a delivery, a family member, a pet, wind, or something more serious. The Skill must distinguish between what it knows and what it infers.
• Pet behavior interpretation: Barking, pacing, scratching, or resting can have many explanations. NestPulse needs to describe observable behavior and avoid diagnosing anxiety, illness, or intent.
• Privacy by design: Home footage is highly personal. I had to make source permissions, local processing, user control, and easy deletion central parts of the design rather than optional extras.
• Avoiding alarm fatigue: If every notification feels urgent, users stop paying attention. The Skill needed a clear priority system and concise summaries.
• Working within the Skill format: I needed to communicate the workflow clearly through SKILL.md and linked Markdown references while fitting the UGREEN Skill Developer Package.
• Designing for real households: A useful assistant must be understandable to every member of the family, not only technical users.

Accomplishments that we're proud of

I am proud that NestPulse turns a NAS from passive storage into an active, privacy-conscious household companion.

Specifically, I am proud of:

• Creating a clear concept for AI-assisted home safety and pet awareness without making privacy an afterthought.
• Combining two practical use cases in one Skill: “Is everything okay at home?” and “What did my pet do today?”
• Designing a simple, human-friendly home brief and pet-day recap format.
• Building a workflow that separates facts, interpretations, and recommended actions.
• Using urgency levels to reduce notification noise and highlight what truly matters.
• Designing the Skill to state uncertainty instead of overclaiming security or health conclusions.
• Making the project adaptable: the same structure can support camera events, smart-home alerts, household notes, maintenance reminders, and emergency-preparedness information.

What we learned

I learned that a good household AI assistant should not try to replace human judgment. Its role is to reduce noise, organize information, and help people make faster, better-informed decisions.

Key lessons include:

• Context matters more than raw data. A timestamp, location, repeated pattern, or user-defined rule can completely change the meaning of an event.
• Trust requires transparency. Users need to know what data the Skill accessed, what it concluded, and why.
• Privacy is a feature, not a limitation. Keeping sensitive household information local makes the NAS a stronger foundation for home AI.
• Clear communication is essential. “Check the back-door camera clip from 22:14” is more useful than a vague warning.
• Pet monitoring needs humility. The Skill should describe behavior and suggest review, not diagnose health conditions or make definitive behavioral claims.
• Good AI workflow design means knowing when not to act. Asking for confirmation is often better than making an uncertain automated decision.

What's next for NestPulse

The next version of NestPulse could become a more complete household awareness companion.

Planned directions include:

• Smart-home integrations: Connect with compatible cameras, doorbells, smart locks, smoke detectors, water-leak sensors, and motion sensors.
• Routine awareness: Learn normal household patterns, such as typical arrival and departure times, while keeping the user in control of what is remembered.
• Pet wellbeing signals: Track general activity patterns over time and surface notable changes for review, while clearly stating that NestPulse does not provide veterinary diagnoses.
• Pet safety alerts: Flag potential concerns such as prolonged distress signals, access to restricted areas, or unusual inactivity, with user-configurable sensitivity.
• Emergency readiness: Maintain an encrypted household emergency plan, contacts, medication list, insurance documents, and evacuation checklist.
• Maintenance guardian: Detect overdue tasks such as smoke-detector battery checks, filter replacements, or security-camera maintenance.
• Family mode: Let household members receive role-based updates, for example a parent receiving urgent alerts while a child receives only simple safety reminders.
• Voice and mobile interaction: Let users ask, “Is everything okay at home?” or “What did my pet do today?” and receive a concise, source-linked answer.
• Stronger evaluation: Add test cases for false positives, missing data, conflicting events, privacy boundaries, and urgent situations.

My vision is simple: NestPulse should help people feel more informed and secure at home—without requiring them to give up control of their data.
