About
Snapmaker U1 Card is an integration with a bundled dashboard card for monitoring and controlling a Snapmaker U1 printer. It talks to the printer directly, so the separate Moonraker integration, extra cards and add-ons are not needed, and setup is done in the UI with the printer's address. It provides live values, pause, cancel, emergency stop and homing controls, cameras, a light, fan and temperature settings, and a firmware update entity. Prints can be started with filament mapping like Snapmaker Orca, placed in a queue, and tracked with history and per-print energy and cost. Filament data can be tied to Spoolman spools per toolhead. Settings cover a power switch with clean shutdown and automatic switch-on and switch-off, plus phone notifications.

Settings
- Printer power switchUsed for the on/off button on the card. Switching off is blocked while printing.
- Power sensor (W)Live power draw, usually from the same plug.
- Energy meter (kWh)Total energy counter. Used for the consumption of each print.
- Electricity price entitySensor or helper with the current price (dynamic tariffs). Empty = fixed price below or the energy dashboard.
- Shut the printer down before cutting powerSends a shutdown to the printer, waits until it is gone plus 10 s, then switches off. If the printer refuses, it is switched off after 10 s like with its rocker switch.
- Switch on automatically when a print is startedStarting a print from the card while the printer is off switches it on and waits until it is ready (about 1–2 min).
- Switch off automatically after a printAfter a finished or cancelled print, once all heaters have cooled down.
- Auto-off below temperatureNozzles and bed must be below this temperature.
- Auto-off delay after the printMinimum time between the end of the print and switching off.
- Switch off after idleHours without a print and without heating, then shut down cleanly and switch off. 0 = off.
- Fixed energy pricePer kWh, used when no price entity is set. Without both, the price from the energy dashboard is used.
- Notify servicese.g. notify.mobile_app_pixel_8. Several are possible.
- Notify on
- Camera for the pictureThe companion app attaches a current image. Also used for the result photo in the history.
- “Almost done” warningMinutes before the estimated end.

From the README
One integration for the Snapmaker U1 in Home Assistant, with its own dashboard card. It talks to the printer directly and covers everything: live values and controls, camera, filament and Spoolman, notifications, energy and cost. No Moonraker integration, no extra cards, no add-ons.
- Start prints with the filament mapping of Snapmaker Orca, including a cost estimate, the file's slicer settings and a warning when a spool will not last
- Queue, pause at a layer, reprint from the history, exclude objects during a print
- Layer view in the colours of the loaded spools with sliders for layer and progress, G-code preview of any file before printing, remaining time calibrated on the real print
