Who am I?

Who am I? 👨‍💻


👋 A smart home enthusiast, daily optimization fanatic and tinkerer, I originally just wanted to "better manage my heating"… then I discovered Home Assistant, and I never really left.

Here, I share what I set up at home: automations, integrations, energy monitoring and fine-tuning for everyday comfort.

You'll find detailed real-world use cases, ready-to-adapt code and honest feedback on what works… and what doesn't, all with one obsession: optimize without over-complicating.

🚀 The origin story: from home automation to global optimization

My journey into home automation started very pragmatically, driven by two essential needs: security and heating control.

I started with mainstream solutions like Blink, then Tapo.

These tools helped me discover the potential of connected homes… but also their limitations:

  • restricted automations,
  • cloud dependency,
  • closed ecosystems,
  • near-zero interoperability between brands.

🔁 The turning point: taking back control

Very quickly, these limitations became blockers. I then chose to migrate to Home Assistant, and progressively replace my devices with Zigbee-based, local and interoperable solutions.

This change marked a real turning point:

  • a centralized system,
  • advanced automations,
  • coherent logic,
  • greater reliability,
  • less dependency on cloud services.

Since then, my setup has never stopped evolving.

❤️ My favourite automations

Some automations have become so natural that I don't even think about them anymore — and that's precisely the sign that they're working perfectly.

🎷 Wake up to music

Five minutes after I wake up, my amplifier turns on automatically and plays a Jazz playlist on shuffle. No manual action, no screen: just the right atmosphere to start the day.

💡 Smart outdoor lighting

I repurposed indoor motion sensors, installed in weatherproof junction boxes outside. They automatically trigger the lights around the house whenever movement is detected. Simple, reliable, and incredibly practical every day.

📬 Smart mailbox detection

My mailbox is connected: mail delivered = instant notification on my phone, mail collected = the notification disappears automatically. No unnecessary reminders, no doubt: the information is accurate and contextualized.

🏗️ My stack & how I work

  • Home Assistant Green as the core of the system
  • a local-first approach
  • automations designed as real processes, not gadgets

I also developed a Home Assistant expert agent, used as a co-pilot to:

  • design,
  • maintain,
  • optimize automations.

Today, a large part of my work relies on:

  • Claude Code,
  • and its MCP, used as an automation engineering tool.

AI isn't there to "do things for me", but to improve the quality of decisions and the consistency of the system.

🧠 The real challenge in home automation (WAF included)

The biggest challenge in home automation isn't the installation, maintenance or bug fixes… it's getting your household to accept and use it.

A technically perfect automation is worthless if:

  • it surprises people,
  • it complicates everyday use,
  • or it creates frustration.

User experience always comes before technical performance.

🔮 Current & upcoming projects

  • Building a connected bird feeder, capable of detecting and recognizing bird species
  • Improving system monitoring, with intelligent alert prioritization
  • Integrating Discord as a central notification and supervision tool
  • Using n8n for complex optimization and alerting workflows
