Smart Kitchen Scales

The kitchen-scale page. For barista-grade espresso workflow see Coffee Roasting & Tracking; for sous-vide / smart appliances see Smart Appliances & Sous Vide; for connected-thermometer pairings see Connected Thermometers; for nutrition / macro logging that depends on weight see Nutrition Tracking — Cronometer; for HA-side smart-appliance integrations see Home Assistant Add-ons; for the firmware-level smart-scale builds see IoT Firmware Platforms and ESPHome / Tasmota.

Coffee-specific (the highest-trust segment)

• ★ ★ Acaia Pearl S / Lunar 2021 — Bluetooth; espresso-bar-grade; flow-rate readings; iOS / Android apps; pairs with Decent Espresso, Aillio, La Marzocco. Premium pricing (~$200–$300) but durable. Default for serious coffee.

• ★ Felicita Arc — Bluetooth; cheaper than Acaia (~$100); good build; flow rate; smaller app ecosystem.
• Brewista Smart Scale II — Bluetooth; pour-over flavored; ~$70.
• Timemore Black Mirror Nano / Pro — Chinese; great spec-for-price (~$60); growing app support.
• DiFluid Microbalance — high-precision; ~$90; pour-over flavored.
• Hario V60 Drip Scale — basic; not smart but the iconic budget pour-over scale.

For the coffee workflow this enables (shot logs, Decent Espresso integration), see Coffee Roasting & Tracking.

Baking-flavored

• ★ OXO Good Grips 11-lb Food Scale — paid; not smart; just the right scale for general kitchen use. Mention because most "smart" baking scales are gimmicky.
• Etekcity Smart Nutrition Scale — Bluetooth; cheap (~$30); pairs with VeSync app + MyFitnessPal; shows macros from a built-in DB.
• Greater Goods Nutrition Smart Scale — paid + app; macros-flagged.
• Drop Scale — sunset; ignore.
• Perfect Bake — sunset; ignore.

Connected hardware ecosystems

• ★ Decent Espresso pairing — Decent's tablet talks Acaia / Felicita over BT; logs every shot's flow + weight + pressure curve. The closest thing to a coffee-IOT-stack. See Smart Appliances & Sous Vide.
• KitchenAid scale-bowl attachment — closed; aging.
• Anova Precision Cooker app — supports BT scale add-on for some workflows; mostly thermometer-flavored.
• Bambino Plus / Breville scale combos — closed cloud.

DIY / FOSS

• ★ Open scale projects — load-cell + HX711 + ESP32 + ESPHome; ~$15 in parts; integrates into HA. The right call if you'll connect a scale to automations. See ESPHome / Tasmota and IoT Firmware Platforms.
• gaggiuino — open hardware espresso machine controller; hooks scale + pump + temp.
• GitHub: openscale / similar — varying maturity.

Apps that consume smart scales

• ★ Beanconqueror — free; OSS; the de-facto coffee-shot logging app; pairs with most BT scales.
  • https://beanconqueror.com
• Acaia Updater + Acaia Coffee — Acaia's first-party apps.
• Filtru, Brewfather Coffee — pour-over / espresso log.
• VeSync (Etekcity) — closed, syncs to MFP.
• Cronometer / MyFitnessPal — manual entry from a generic scale; few support direct BT pairing.
• Decent app — closed but very capable; the espresso-tablet ecosystem.

What "smart scale" actually buys you

• ★ Flow rate display in real time — for espresso shot dialing, this is the killer feature. Watching grams/sec as you pull tells you if grind is right.
• Auto-tare on cup placement — small luxury; hard to go back.
• Shot-log auto-export — feeds Beanconqueror / Decent.
• Macro lookup at the scale — gimmicky for serious users; helpful for casual macro tracking; you're better off weighing into Cronometer.
• The bad reasons: "smart" doesn't make a scale more accurate; a $20 OXO is plenty for baking.

Practical guidance

• ★ For baking, an unconnected $20 scale is the right answer. Smart features here are mostly noise.
• For espresso, Acaia or Felicita is worth the money. The flow-rate visualization changes how you dial in shots.
• Resolution is more important than max weight for most kitchens. 0.1 g matters; 5 kg is plenty. 0.01 g is barista-bench territory.
• Bluetooth latency under 100 ms is required for live espresso. Cheap scales lag.
• Battery type matters. USB-C rechargeable beats AAA on cost-of-ownership.
• Don't buy a smart scale to log macros. Cronometer / MFP entry by hand is faster than fiddling with BT pairing.

Pricing reality (mid-2026)
