What's next.

POST /update takes an image on the LAN, gated by an update key — a node with no key set refuses firmware from everyone. A wrong or truncated image is refused before the boot slot is touched, and a node that took a bad-but-bootable image reverts to its factory image with one call. An image that cannot boot at all needs no call: the bootloader puts the node back on the image it was running, which was proven by pushing one that panics on purpose. All of it on real nodes over Wi-Fi.

The node wraps and columns receipt text itself: printWidthCols (measured default 48), per-receipt overrides, cut clearance. Tuning a node is a curl, not a reflash.

A historical bench measurement after a Wi-Fi power-save fix in firmware 1.0.9. This is a recorded result for that setup, not a timing guarantee for every printer and network. Drawer control uses the local API; raw print-job drawer commands are dropped.

GET /scans keeps a verdict per read — rejects included, with the reason. Symbology is labeled aim when the scanner transmitted it and inferred when it's a guess. Decode policy (read modes, timeouts, allow-lists, layouts) is set over PUT /config.

Nodes beacon over UDP and serve GET /peers to discover other nodes heard on the same local network. This does not enumerate devices on other networks or every node in your account.

Sign in with an emailed code, claim a node with the code we email when it ships, see your fleet and when each node was last seen. Release any time — the node keeps working either way.

Proxy Node Raw has a checkout with optional accessories priced per board. Current ordering status, included items and available accessories are on the product page. Checkout uses our hosted service; printing stays on your LAN.

Choose how each node updates — automatically inside a window you pick, or held on a version you name — and hand one an image immediately with Update now. Releases go out by rollout percentage, and a build can be pinned or withdrawn. A bench node pulled a release, waited out a quiet spell, rebooted onto it and reported back, with nobody in the room.

Ethernet and Wi-Fi failover were exercised on an Ethernet-equipped bench setup. This is firmware work on different hardware: Proxy Node Raw has no Ethernet port, and the result does not establish that Station Hub's custom board is finished or qualified.

GET /scale serves weight, unit and stability from a HID Point of Sale scale, and a scale that has gone to sleep says so instead of reading a confident zero. Three absences are modelled apart from each other: asleep, absent, and refused for want of a USB channel on a full bus.
