Protocol Details

Service UUID: 0000fff0-0000-1000-8000-00805f9b34fb
Write Characteristic: Dynamic discovery by GATT properties (fallback: 0000fff1-0000-1000-8000-00805f9b34fb)
Format: ASCII AT commands terminated with \r\n (no checksum)

Detection

Auto-detection uses:

  1. Device name prefix SUTA-
  2. FFF0 service UUID for high confidence

Accessory/smart-mattress subtypes are intentionally excluded because they use a different protocol:

  • SUTA-MOON
  • SUTA-TEMP
  • SUTA-RBHC
  • SUTA-DRAWER
  • SUTA-STORAGE
  • SUTA-SOFA
  • SUTA-YOGABED
  • SUTA-ROLLSOFA

Packet Format

Commands are plain UTF-8 text:

"AT+...<CR><LF>"

Example:

AT+CTRL=BOTH BACK UP\r\n

Implemented Commands

Motor Control

Action Command
Head Up AT+CTRL=BOTH HEAD UP
Head Down AT+CTRL=BOTH HEAD DOWN
Back Up AT+CTRL=BOTH BACK UP
Back Down AT+CTRL=BOTH BACK DOWN
Legs/Foot Up AT+CTRL=BOTH FOOT UP
Legs/Foot Down AT+CTRL=BOTH FOOT DOWN
Lumbar/Tilt Up AT+CTRL=BOTH T/L UP
Lumbar/Tilt Down AT+CTRL=BOTH T/L DOWN
Stop All AT+CTRL=BOTH STOP

Note: head is mapped to the same upper actuator commands as back for compatibility with existing entities.

Presets

Action Command
Flat AT+MODE=BOTH FLAT
Zero-G AT+MODE=BOTH ZEROG
Anti-Snore AT+MODE=BOTH SNORE
TV AT+MODE=BOTH TV
Memory 1-4 Recall AT+MODE=BOTH M1 ... M4
Memory 1-4 Save AT+SETMODE=BOTH M1 ... M4

Lights

Action Command
Light On AT+ENABLE=LIGHT
Light Off AT+DISABLE=LIGHT

Sync / Split King

Action Command
Sync Slave On AT+SINSLAVE=ON
Sync Slave Off AT+SINSLAVE=OFF

For split-king beds, enabling sync slave mode makes this side mirror the other side's movements.

Massage

Massage uses three parameters per zone: Timer (T), Duty Cycle (DT), and Level (LV).

Action Command Values
Head Timer AT+MASS=BOTH HEAD T<param> e.g. T00M
Foot Timer AT+MASS=BOTH FOOT T<param> e.g. T00M
Head Duty Cycle AT+MASS=BOTH HEAD DT<value> 00 (off), 20, 33, 50
Foot Duty Cycle AT+MASS=BOTH FOOT DT<value> 00 (off), 20, 33, 50
Head Level AT+MASS=BOTH HEAD LV<value> 00 (off), 10, 20, 30
Foot Level AT+MASS=BOTH FOOT LV<value> 00 (off), 10, 20, 30

Duty cycle cycles: 00 -> 20 -> 33 -> 50 -> 00. Level cycles: 00 -> 10 -> 20 -> 30 -> 00. Setting DT to 00 for both zones turns off all massage.

Command Timing

Operation Repeat Count Delay Notes
Motor movement (default) 7 150ms Bed-type pulse defaults
Stop 2 100ms Sent after movement
Preset recall 1 n/a Single command, bed firmware handles full move
Save memory 5 150ms Program command burst

Notes

  1. The app includes many extra AT commands (massage, lock, beep, calibration, scheduling). Current integration support is focused on core bed control and presets.
  2. The SUTA accessory family uses a different binary protocol and is intentionally excluded from SUTA bed-frame detection.
  3. Characteristic UUIDs are discovered at runtime from service properties, not hardcoded in the app.
