Protocol Details

The LinonPI protocol uses a multi-service architecture where each motor has its own BLE service with direction-specific characteristics. This is different from most beds which use a single service with command bytes.

BLE Services

Function Service UUID
Head Motor 0000abcb-0000-1000-8000-00805f9b34fb
Feet Motor 0000c258-0000-1000-8000-00805f9b34fb
Lights 0000d07b-0000-1000-8000-00805f9b34fb
DFU 0000f92a-0000-1000-8000-00805f9b34fb

Characteristics (same UUIDs in each motor service)

Function Characteristic UUID

Motor Commands (2-byte)

Commands are written to the direction-specific characteristic within the appropriate service:

Action Service Characteristic Bytes
Head Up abcb 01ac (UP) [0x01, 0x00]
Head Down abcb bae9 (DOWN) [0x01, 0x00]
Head Stop abcb same as move [0x00, 0x00]
Feet Up c258 01ac (UP) [0x01, 0x00]
Feet Down c258 bae9 (DOWN) [0x01, 0x00]
Feet Stop c258 same as move [0x00, 0x00]

Preset Commands (written to POSITION characteristic 143d in both services)

Command Bytes Characteristic Services Description
Flatten [0x3F, 0x81, 0x00, 0x00, 0x00, 0x00] POSITION (143d) Head + Feet Go to flat position
Recall Position [0x3F, 0x80, 0x00, 0x00, 0x00, 0x00] POSITION (143d) Head + Feet Go to saved memory position
Save Position [0x3F, 0x40, 0x00, 0x00, 0x00, 0x00] POSITION (143d) Head + Feet Save current position to memory

Memory Commands (written to MEMORY characteristic fb6e)

Command Bytes Description
Svane Position [0x03, 0x00] Comfort preset (similar to zero-g)
Read Position [0x3F, 0xFF, 0x00, 0x00, 0x00, 0x00] Query current position

Implementation notes:

  • preset_flat, save, and recall use POSITION (143d) writes in head + feet services.
  • Compatibility fallback also writes these preset packets to MEMORY (fb6e) if present.
  • The integration provides two software memory slots by reading raw POSITION payloads for head/feet and replaying those bytes on recall.

Light Commands (6-byte, written to LIGHT_ON_OFF a8e0)

Command Bytes Notes
Light On [0x13, 0x02, 0x64, 0x01, 0x00, 0x64] brightness=100
Light Off [0x13, 0x02, 0x00, 0x00, 0x00, 0x00]
Set Intensity [0x13, 0x02, brightness, on_flag, 0x00, 0x64] brightness 0-100

Position Feedback

Position data available via notify on the POSITION characteristic (0000143d-...) in each motor service:

  • Head position: Enable notify on 143d in service abcb
  • Feet position: Enable notify on 143d in service c258

Position is returned as a raw byte value (0-100), which is scaled to estimated angles:

  • Head: 0-60°
  • Feet: 0-45°

Device Detection

Detected by:

  • Service UUID: 0000abcb-0000-1000-8000-00805f9b34fb (head service)
  • Device name pattern: "Svane Bed" (case-insensitive)

Command Timing

  • Repeat count: 10 (default)
  • Repeat delay: 100ms
  • Stop: Always sent after movement commands

Related Protocols

The Svane Remote app also supports:

  • JMC400 devices - Use the Jensen protocol, detected by "JMC" in device name
  • OKIN-i devices - Classic Bluetooth (not BLE), not supported by this integration

Notes

  1. The "LinON" name in the protocol appears to be Svane's internal product name for their bed controller. It is NOT related to Linak despite the similar-sounding name.

  2. The multi-service architecture means the same characteristic UUID exists in multiple services. The controller must write to the correct service to control the intended motor.

  3. Svane is a Norwegian bed manufacturer. Their beds are primarily sold in Scandinavia.
