Exploring advanced Home Assistant triggers including calendar, webhook, zone, and NFC tag automations in a modern smart home setup.
Home Assistant has been running on my tiny Proxmox cluster for months, but I’ve only used it as a background service until now. It’s time to get hands-on and make it truly useful in my home. I’m finally ready to stop treating Home Assistant as a background service and start automating my home. To kick things off, I’ve been exploring some lesser-known triggers that go beyond standard motion-based setups. Here are four Home Assistant triggers I’m excited to try, and why they’re next on my list:
1. The Calendar Trigger
I’ve recently added four smart bulbs to my front porch. While having them turn on and off at set times is a great start, it’s not very flexible. With the Calendar trigger, the lights can adjust automatically to my schedule, turning on or off based on my calendar events. This means if I’m away or my plans change, my porch lights will match my real-time needs, eliminating the need for manual overrides.
2. The Webhook Trigger
I love the idea of Home Assistant interacting with things outside my home network. The Webhook trigger makes this possible by allowing external services or my computer to trigger automations. For example, I plan to set up a digital “On Air” display outside my office door. By firing a webhook from my PC when I start a call, I can instantly let others know I’m busy. This trigger benefits my workflow by tightening integration between my home setup and computer-based activities.
3. The Zone Trigger
To make my home more intuitive, I will use the Zone trigger with kitchen motion sensors. The main benefit is context-aware automation: late at night, the sensors will activate a low-light scene instead of full brightness. This setup provides comfort and avoids harsh lighting during late-night water trips, enhancing both convenience and ambiance without manual intervention.
4. The Tag Trigger
I’m sitting on a pile of unused NFC stickers, so the Tag trigger is the perfect opportunity to put them to good use. The main benefit is easy tracking of plant care: until I can implement advanced moisture sensors, scanning an NFC tag after watering instantly logs the event. This bridges the gap until my custom hardware is ready, helping me build good care habits and keeping records up to date with minimal effort.
Home Assistant has so many layers that it’s easy to stay stuck in basic automations. I’m excited to see what these triggers can do for my home. If you’ve been procrastinating on your setup, maybe it’s time to experiment together.
A cinematic visualization of the conflict between rapid file system innovation and the Linux kernel’s strict stability and release management process.
In operating systems, file systems are the foundation of stability. Users expect their storage layer to be uneventful, predictable, and above all, safe.
But behind the scenes of the Linux kernel, the development of Bcachefs—the modern Copy-on-Write (COW) file system slated to compete with Btrfs and ZFS—has been anything but boring.
Following a series of heated standoffs between Linus Torvalds and Bcachefs lead maintainer Kent Overstreet, the Linux creator made a dramatic executive decision: Bcachefs has been dropped from the mainline Linux kernel.
This conflict highlights the tension between rapid, visionary development and the strict discipline needed to manage software for billions of devices worldwide.
Before diving into the drama, it’s important to understand the promise of Bcachefs and why its development became so significant.
Merged into the mainline Linux kernel late in 2023, Bcachefs was hailed as the next-generation file system for the Linux ecosystem.
For years, Linux users have faced challenges with advanced storage features:
Btrfs was built into the kernel but has historically suffered from rocky reliability (particularly around RAID 5/6 write holes).
ZFS was highly stable and feature-rich, but licensing conflicts (GPL vs. CDDL) kept it out of the mainline kernel, requiring users to install it as an out-of-tree module.
Bcachefs promised to bridge this gap with a high-performance, feature-rich, Copy-on-Write design. Its message was simple: “The file system that doesn’t eat your data.” It brought snapshotting, encryption, multi-drive management, and ZFS caching directly into Linux.
The Cardinal Sin: Features in the Release Candidate Phase
The breaking point did not occur because of a bug. It occurred because of a fundamental breach of the Linux kernel’s development protocol.
During the release cycle, kernel development follows a strict, consensus-based timeline:
1. The Merge Window: A two-week period where new features, drivers, and subsystems are merged into the upcoming kernel version.
2. The RC Phase: Code is frozen; developers may only fix bugs and regressions to ensure release stability.
During the RC phase, Kent Overstreet submitted a pull request containing a major change called “journal-rewind.” The feature was designed to improve Bcachefs’ repair and recovery functionality—a highly sensitive part of any file system.
Linus Torvalds objected. Introducing a structural change to journaling during the RC phase violates the kernel’s core safety rules.
Theodore Ts’o, the long-time maintainer of the robust ext4 file system, also weighed in. He pointed out that modifying journaling code so late in the cycle risks introducing severe, unpredictable regressions that could destroy user data—the exact opposite of what a file system is supposed to do.
A Clash of Philosophies: Rules vs. Agility
The debate quickly devolved from a technical discussion into a clash of development philosophies.
Kent Overstreet argued that rules should be flexible when fixing data integrity. He felt delivering critical recovery features outweighed following the standard timeline, claiming Bcachefs needed more agility than traditional file systems like ext4.
Torvalds and Ts’o countered with a different reality: the rules are what protect user data.
In Linux’s vast ecosystem, a regression in a core file system can brick servers and corrupt data. Strict merge windows are crucial safety gates, proven over decades.
The Parting of Ways
After a tense back-and-forth, Overstreet resubmitted the patch, arguing that other file systems, such as XFS and Btrfs, had been granted similar flexibility in the past.
Linus merged the patch to unblock the immediate release, but reached his limit. He made it clear that because Overstreet rejected the consensus-based rules of kernel development and refused to accept standard oversight, Bcachefs could no longer remain in mainline Linux.
Torvalds officially dropped support for Bcachefs, parting ways with the filesystem.
What This Means for the Future of File Systems
The removal of Bcachefs from the mainline kernel is a significant setback for the project, influencing not only its immediate trajectory but also shaping how future filesystems might approach kernel integration and community process.
1. Out-of-Tree Maintenance
Bcachefs will now be maintained “out-of-tree,” as ZFS is. Developers must package and compile modules for each release, which creates friction for users because Bcachefs won’t work natively with standard distributions.
2. Slowed Adoption
Mainstream distributions are unlikely to support filesystems not in the mainline Linux kernel. Bcachefs will likely be limited to homelabbers, power users, and custom distributions.
3. A Precedent for Kernel Governance
This incident reinforces the authority of mainline kernel maintainers and sets a precedent for how future contributors should navigate development protocols. It signals to all developers that adherence to established processes will remain essential for the inclusion and long-term success of new filesystems in Linux.
Final Thoughts
The Bcachefs drama is a tragedy of open-source engineering. Bcachefs is a brilliant, highly innovative filesystem that solved problems other filesystems spent decades avoiding.
But in enterprise and system-level software, how you build is just as important as what you build.
The Linux kernel is the most successful collaborative software project in human history because it prioritizes safety, discipline, and consensus over individual speed. When a developer refuses to play by those rules, the system self-corrects—even if it means losing some of the most promising storage technology of the decade.
Support stable systems, open standards, and the rigorous engineering that keeps our digital world running.
A dramatic editorial illustration exploring the tension between Bambu Lab’s proprietary cloud ecosystem and the open-source 3D printing community following the OrcaSlicer API controversy.
But with great hardware success comes a classic software dilemma.
This month, a quiet storm flashed into the spotlight when Bambu Lab pressured a solo open-source developer to take down a fork of **OrcaSlicer** that reconnected the slicer directly to Bambu’s proprietary cloud infrastructure.
By trying to protect their API, Bambu Lab angered power users. They gave the open-source alternative a megaphone. Their relationship with the open-source community came under a microscope.
Before we dig into what happened, why it backfired, and what it means for the future of smart hardware, let’s take a step back and understand the roots of this controversy.
Slicers, Forks, and the Open-Source Roots
To understand the community’s reaction, it is necessary to examine the history of 3D printing software.
1. **Slic3r** was the original pioneer.
2. **Prusa Research** took Slic3r and heavily evolved it into the incredible **PrusaSlicer** (under the open-source GNU GPL v3 license).
3. **Bambu Lab** entered the market and built its own slicer, **Bambu Studio**, by forking PrusaSlicer.
4. The community, wanting even more advanced calibration tools and experimental features, then forked Bambu Studio to create **OrcaSlicer**.
Forking and modifying are allowed under the GPL v3 license. Bambu Lab had to keep Bambu Studio open source because it was built on PrusaSlicer. This open ecosystem enabled Bambu Lab to release a world-class slicer on day one.
But there was one proprietary element: **The Bambu Network Plugin**.
The Closed-Loop Cloud in an Open-Source World
Bambu Studio is open-source. But the plugin that connects to Bambu’s cloud servers is closed-source and proprietary. This allows you to send prints over the internet, watch your camera feed, and monitor prints via Bambu Handy.
This created a major friction point. Many users prefer **OrcaSlicer** because of its superior calibration patterns and fine-grained controls, but they still own Bambu printers and want to use Bambu’s cloud features.
To address this issue, a solo developer wrote code to interface with Bambu’s cloud APIs, creating a fork that allowed OrcaSlicer to connect directly to the Bambu cloud.
Following this, legal representatives became involved.
The Takedown and the “Bambura Streisand” Effect
Bambu Labs cited security and terms of service on unauthorized API use. They pressured the developer to take down the repository. The developer complied.
From a traditional corporate legal perspective, this was a standard intellectual property win. But in the tech world, this is where the **Streisand Effect** kicks in.
The Streisand Effect is a phenomenon in which an attempt to hide, remove, or censor a piece of information has the unintended consequence of publicizing it further.
By forcing the takedown, Bambu Lab triggered several things:
Forums, Subreddits, and YouTube channels erupted with backlash. Users criticized a company built on open-source contributions. They saw Bambu Lab gatekeeping a cloud API from its own paying hardware customers.
Thousands of casual users had never heard of the OrcaSlicer cloud fork. After the takedown made headlines, everyone learned about it.
The controversy pushed users to abandon Bambu’s cloud. They switched to local-only LAN Mode or set up open-source print servers like **Obico** or **OctoPrint**.
By shutting down a widely desired integration, Bambu Lab underscored the central concern: vendor lock-in versus user autonomy, sharpening the community’s main frustratio**n.**
Security vs. Control: The Corporate Excuse
Bambu Lab’s official stance is that restricting access to their cloud API is necessary for security reasons. They argue that if third-party software gains uncontrolled access to their cloud servers, it could increase the risk of unauthorized actions, disrupt server operations, cause instability, expose user credentials, or leave printers more vulnerable to attack. Bambu Labs maintains that controlling API access helps ensure only trusted software can interact with their cloud infrastructure, protecting users and devices.
While security is a valid concern, the open-source community remains highly skeptical.
If security were the sole motivator, the solution would be documentation and open authorization. For example, OAuth. If Bambu Lab provided a secure, rate-limited way for third-party tools to authenticate with their cloud API, developers wouldn’t need to write “unauthorized” forks.
When a company uses legal pressure rather than enabling developers, it signals a prioritization of control over genuine security—heightening the core tension at stake.
The Lesson for Smart Hardware Companies
The “Bambura Streisand” incident is a warning shot for every modern hardware company.
Building your product on open-source means following those rules. You cannot rely on community goodwill to build your software. Then use corporate gatekeeping to lock users out of the hardware they purchased.
Bambu Lab should recognize **interoperability as a feature, not a threat**. Embracing developers who want to build integrations for OrcaSlicer, Home Assistant, or custom dashboards adds value. It makes their printers more valuable.
Until such changes are made, the community will continue its development efforts and advocate for open local control.
Support open hardware and free code for the benefit of the entire community.
Welcome, 2026! This year I’m going to get my hands a little dirtier by shifting from theory-heavy exploration into something more concrete: real hardware, real experiments, real mistakes—and the lessons that come from all of it.
This year started with three repurposed Lenovo 720q Tiny PCs. They’re not new; in fact, they’re e-waste from my job, since they’re too old to upgrade to Windows 11. But they are more than capable of becoming something useful!
So I did what any Linux enthusiast with curiosity and a desire to set up a home lab would do. I turned them into a Proxmox cluster.
Why a Proxmox Cluster?
I’ve written about Linux systems from the perspective of a daily driver: desktops, workflows, tools, and configuration. But increasingly, my curiosity has shifted more towards infrastructure—how systems run behind the scenes.
Proxmox sits at an interesting intersection:
Linux-based
Open source
Widely used in homelabs and
Powerful enough to do real work
Rather than reading about Proxmox in the abstract, I wanted to learn it the only way that really sticks: by building something real and seeing what breaks.
The Cluster: Small Machines, Big Lessons
The cluster itself is modest:
Three Lenovo 720q Tiny PCs
Repurposed hardware instead of new purchases
Low-power draw
Quiet enough to live outside a data center
Just complex enough to be educational
I plan to write about
Initial setup and configuration decisions
Storage choices and mistakes
Networking confusion
Clustering quirks
Backup strategies
Updates that go smoothly—and the ones that don’t
Things I wish I’d known earlier
This won’t be a polished “how-to guide from an expert.” It will be a learning journal—documenting what works, what doesn’t, and why.
Learning Proxmox the Honest Way
There’s a lot of Proxmox content online. Much of it assumes:
Prior virtualization experience
Comfort with enterprise terminology
A willingness to gloss over mistakes
That’s not how I learn, and it’s not how I want to write.
This year at Einstein’s Saloon, you’ll see:
Incremental progress
Honest missteps
Configuration experiments
Rebuilds
Revisions
“I broke this, and here’s what I learned” posts.
If you’re curious about Proxmox but intimidated by it, this series is for you.
Expanding the Scope: 3D Printing Joins the Saloon
Alongside virtualization, another hands-on tool has become a bigger part of my daily tech life: 3D printing.
While it may not look like traditional Linux territory at first glance, 3D printing fits naturally into the same mindset:
Open-source software
Tinkering and iteration
Hardware meets software
Learning by doing
Solving real problems with tools you control
In 2026, I’ll be writing about:
How I’m using my 3D printers
Practical projects
Lessons learned from failed prints
Workflow tweaks
3D modeling
How open-source tools fit into the process
Why 3D printing isn’t just a novelty
I won’t be writing about flashy figurines, but about useful, repeatable outcomes—the same philosophy that drives everything else here.
What Einstein’s Saloon Will Be in 2026
This year, the site will lean into:
Real systems, not hypotheticals
Learning in public
Repurposing hardware
Open-source infrastructure
Practical experimentation
Honest documentation
Less “perfect setups” and more “here’s what actually happened.”
Einstein’s Saloon remains the genius bar for the free and open-source community, but in 2026, the genius will look a little messier.
Looking Ahead
If you’re interested in
Proxmox without the enterprise gloss
Building useful systems from leftover hardware
Watching someone learn infrastructure from the ground up
Practical Linux-adjacent projects
3D printing with purpose
Then you’re in the right place.
Pull up a stool; let’s build, break, and learn together in 2026!
