HA DeskLink – free open-source desktop companion (Windows/Linux/macOS): HA sensors on your desktop, your PC sensors in HA

[TechFlipsi]

Hi everyone,

I’d like to introduce HA DeskLink, a free, open-source desktop companion for Home Assistant (GPL-3.0). It connects your computer and HA in both directions:

Home Assistant → Desktop

• Live sensor values (temperatures, energy, lock states, motion…) directly in the taskbar / system tray
• Desktop widgets (Windows & Linux) for sensors and entity controls
• Toggle lights, switches and scenes from the tray menu
• Native desktop notifications when automations fire
• Optional embedded dashboard view — no browser needed

Desktop → Home Assistant

• PC status pushed into HA as sensor entities: CPU load, memory, disk space, uptime — so your automations can react to your computers

New in v5.0.5: native Music Assistant player integration, desktop widgets, and Sendspin streaming support.

Everything runs locally on your own network — no cloud, no subscription. Platforms: Windows (installer), Linux (tar.gz with systemd service + autostart), macOS (experimental).

• Windows: GitHub - TechFlipsi/ha-desklink-windows: HA DeskLink for Windows – free open-source desktop companion for Home Assistant: live smart-home sensors in the taskbar/tray, PC system sensors (CPU, RAM, disk) pushed into Home Assistant, entity controls and toast notifications. Native C#/.NET app, fully local, no browser. · GitHub
• Linux: GitHub - TechFlipsi/ha-desklink-linux: HA DeskLink for Linux – free open-source desktop companion for Home Assistant: live smart-home sensors in the tray, PC system sensors (CPU, RAM, disk, uptime) pushed into Home Assistant, entity controls and toast notifications. tar.gz build with systemd daemon and autostart. Actively developed, few external testers so far. · GitHub
• Landing page: techflipsi.github.io/ha-desklink

Feedback welcome — especially what you’d want to see on your own desktop.

It’s not really clear from your post or on your website. Are desktop notifications with images supported? Mainly for camera notifications.

Hi eriri, thanks for checking out HA DeskLink!

Short answer: not yet. Desktop notifications currently support text plus action buttons (actionable notifications), but no image attachments — so camera snapshots can’t be shown in the toast right now.

That said, we’d be happy to build it in on request! If you’d like this feature, just open an issue on GitHub or drop by our Discord: Issues · TechFlipsi/ha-desklink-windows · GitHub · TechFlipsi Projekte

Hi eriri, good news — we’ve just built this in! Desktop notifications now support image attachments (HA companion-style image key, including camera snapshots via /api/camera_proxy/... and media paths like /media/local/...). The image shows directly in the desktop toast — click it to view full size.

It ships with v5.0.6, releasing on Windows + Linux today.
