It has 59 installs sharing analytics, works locally and was last updated November 13, 2026. 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. Automatic summary of the README and code of Ironoxx/ha-snapmaker-u1-card.

No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Snapmaker U1 - **Host** - **Port** - **Moonraker API key (optional)** Also asked when changing the connection. ### Settings - **Printer power switch**: Used 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 entity**: Sensor or helper with the current price (dynamic tariffs). Empty = fixed price below or the energy dashboard. - **Shut the printer down before cutting power**: Sends 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 started**: Starting 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 print**: After a finished or cancelled print, once all heaters have cooled down. - **Auto-off below temperature**: Nozzles and bed must be below this temperature. - **Auto-off delay after the print**: Minimum time between the end of the print and switching off. - **Switch off after idle**: Hours without a print and without heating, then shut down cleanly and switch off. 0 = off. - **Fixed energy price**: Per kWh, used when no price entity is set. Without both, the price from the energy dashboard is used. - **Notify services**: e.g. notify.mobile\_app\_pixel\_8. Several are possible. - **Notify on** - **Camera for the picture**: The companion app attaches a current image. Also used for the result photo in the history. - **“Almost done” warning**: Minutes before the estimated end. ### After setup - **Printer power switch**: Used 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 entity**: Sensor or helper with the current price (dynamic tariffs). Empty = fixed price below or the energy dashboard. - **Shut the printer down before cutting power**: Sends a shutdown to the printer, waits until it is gone plus 10 s, then switches off.
