Technical field notes: Home Assistant, SAP, Microsoft 365, ESP and homelab

A compact starting page for the practical technical articles on Sascha’s Blog: Home Assistant, SAP, Microsoft 365, ESP, Grafana and homelab notes.

I write a lot of notes while building things: small Home Assistant fixes, ESP experiments, Microsoft 365 integration work, SAP oddities, Grafana setups, and the occasional hardware review.

This page is not meant to be a full archive. It is the short version: the posts that have actually helped people before, grouped by topic, so you do not have to dig through the whole blog.

If you are here for one specific problem, start with the closest section below. Most of these articles came from something I had to solve myself, not from a content calendar.

MCP, UI automation and small tools

MCP server for shadcn/ui automation

The one I would start with if you are building developer tooling around MCP and UI components.

Home Assistant and smart home

Shelly Wall Display with Home Assistant

A practical setup note, including the parts that are only obvious after mounting and trying it.

Home Assistant e-ink information panel

A small dashboard project that still answers a very concrete search intent.

Teams status in Home Assistant

Useful if your home setup and work tooling overlap a bit too much.

WLED sunrise routine for stair lights

A small automation with a visible everyday result.

JavaScript, npm and developer workflow

Versioning in npm

Semver, npm versioning and the little traps around package releases.

Edit files with Visual Studio Code over SSH

A practical remote-editing note for servers and homelab work.

SAP, Microsoft 365 and enterprise integration

Fetching data from SAP SuccessFactors via OData and OAuth

One of the articles people actually searched for: auth, OData and SuccessFactors without pretending it is nicer than it is.

Syncing users between SAP and Entra ID

A useful companion topic for identity and HR master data flows.

Search, connectors and the reality of getting enterprise content into a useful index.

Azure B2C logout across services

Logout sounds boring until you have several services and sessions involved.

Homelab, Grafana and networking

Provision Grafana datasources

Yes, the slug has the typo. The topic still had search demand.

Provision Grafana dashboards

The dashboard side of the same Grafana setup story.

Homeserver setup with Traefik

Reverse proxy, services and the kind of setup that grows slowly over time.

Route media traffic over Mullvad VPN with OPNsense

A more specific networking note with a surprisingly clear query pattern.

ESP and hardware tinkering

Flash an ESP01 device

Old-school tinkering content, but people searched for it.

Measure voltage with an ESP controller

A simple electronics problem that keeps coming back in small projects.

Gear reviews that had search demand

Logitech MX Master 3S review

This one had huge impressions. It should only stay if it keeps a real, personal angle.

Hollyland Lark M2 review

Also high-impression review content. Worth keeping if it is clearly hands-on and not affiliate fluff.

What I would read first

If I had to pick only a few starting points, I would use these: the shadcn MCP article for current developer tooling, the Shelly Wall Display article for smart home work, the SuccessFactors OAuth article for enterprise integration, and the ESP01 flashing note for hardware tinkering.

The rest is intentionally kept as notes from the field. Some posts are polished, some are rougher, but the useful ones usually came from a real problem first.
