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.

60× faster than the 9–24 s Wi-Fi power-save stall it replaced. Measured on real hardware, fixed in firmware 1.0.9.

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, so one known IP reaches the whole fleet on the LAN.

Sign in with an emailed code, claim a node with the code on its printed slip, see your fleet and when each node was last seen. Release any time — the node keeps working either way.

The Station Hub is for sale — Stripe checkout shows price and shipping. Checkout is the only cloud on this page; the print path 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 Releases go out by rollout percentage, and a build can be pinned or withdrawn.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.

A cabled node takes a DHCP lease and serves over the wire — 100 Mbps full duplex on the first boot of the first board ever wired for it. Pull the cable and it is serving on Wi-Fi 2.9 s later; put it back and it returns in 2.0 s, with uptime climbing straight through both. A cabled node holding no credentials never raises a setup network.

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.
