Hardware Integration

Weigh it. Price it. Done.

Budy POS talks to Acaia Lunar, Pearl and Pyxis scales over Bluetooth — so weight on the scale becomes a priced line item on the receipt, instantly.

The scale becomes the cashier.

Put flower on the pad — Budy streams the weight over Bluetooth LE and multiplies it by the variant's price-per-gram in real time. The cart line updates as the number on the LCD settles. No manual entry, no rounding, no math.

  • Live weight streamed over Bluetooth LE
  • Auto-tare fires seconds after connect
  • Add-mode accumulates across multiple bags
  • Grams, ounces or pounds — your call
  • Priced line items written straight to the receipt

Every gram, priced at the jar.

Every dispensary sale that prices by the gram runs through this one flow. Pull flower from the jar, drop it on the pad, and the POS shows the weight, the per-gram price and the line total in real time. Budtenders stop calculating, customers stop second-guessing, and the receipt always matches the scale.

  • Pre-packed eighths, quarters, halves
  • Loose flower weighed out at the counter
  • Multi-bag orders accumulate in add-mode
  • Live price updates as flower goes on and off
  • Zero manual math at the register

Pair once. Reconnect forever.

Scan once in Settings → Devices and Budy remembers your scale for good. On every app launch it walks back into range and reconnects silently. If the Lunar sleeps mid-shift, the next weigh wakes it up — no tapping through menus to re-pair.

  • Auto-reconnect on launch, on by default
  • Device identity persisted locally
  • Works fully offline — weights never leave the device
  • Supported on Android today; iOS rolling out
