DS-501 LoRaWAN Smart Plug User Guide

Device Information: Model DS-501, devEui ffffff1000048920, gateway IP 192.168.31.205, Modbus Slave ID 3, BACnet Device ID 102

1 Protocol Overview

The DS-501 reports switch state, lock state, voltage, current, active power, energy consumption, and signal quality on Fport 210.

Payload format (Fport 210):

Byte Field Description
0 Reserved Always 0x00 (protocol version)
1 … N TLV pairs [Type(1 B)][Value(N B)] … repeating until end

Each Type byte determines the field name and the number of following value bytes:

Type Value Bytes Field Name Encoding Scale Unit Notes
0x01 1 model uint8 — — Model code = 0x48
0x22 1 switch uint8 — — 0=OFF 1=ON (relay state)
0x96 1 lockState uint8 — — 0=unlocked 1=locked
0x79 4 timestamp uint32 BE — s Device local Unix timestamp (0 if no RTC)
0x80 4 timerStatus bitfield32 BE — — Bit 0=timerCloseEnabled Bit 1=timerOpenEnabled Bit 30=timerLockEnabled Bit 31=timerUnlockEnabled
0x97 2 voltage uint16 BE ÷10 V e.g. 0x09C4=2500 → 250.0 V
0x98 2 current uint16 BE ÷100 A e.g. 0x0064=100 → 1.00 A
0x99 2 activePower int16 BE ÷100 W Signed; e.g. 0x00C8=200 → 2.00 W
0x9A 4 energy uint32 BE ÷100 kWh Cumulative energy; e.g. 100 → 1.00 kWh

JavaScript Decoder Example:

// DS-501 Smart Plug — Fport 210 uplink decoder
function decodeUplink(bytes) {
  var i = 1, r = {};
  function u16(b,o){ return (b[o]<<8)|b[o+1]; }
  function i16(b,o){ var v=u16(b,o); return v>32767?v-65536:v; }
  function u32(b,o){ return ((b[o]<<24)|(b[o+1]<<16)|(b[o+2]<<8)|b[o+3])>>>0; }
  while (i < bytes.length) {
    var t = bytes[i++];
    switch (t) {
      case 0x01: r.model       = bytes[i++]; break;
      case 0x22: r.switch      = bytes[i++]; break; // 0=OFF  1=ON
      case 0x79: r.timestamp   = u32(bytes,i); i+=4; break;
      case 0x80: {
        var bits = u32(bytes,i); i+=4;

        r.timerUnlockEnabled= (bits&0x80000000)!==0;
        break;
      }
      case 0x96: r.lockState   = bytes[i++]; break;
      case 0x97: r.voltage     = u16(bytes,i)/10;  i+=2; break; // V
      case 0x98: r.current     = u16(bytes,i)/100; i+=2; break; // A
      case 0x99: r.activePower = i16(bytes,i)/100; i+=2; break; // W
      case 0x9A: r.energy      = u32(bytes,i)/100; i+=4; break; // kWh

Compatibility note: LPP.js is developed and tested against ChirpStack v4.17.0. The ChirpStack JavaScript codec API may differ across versions — if you are running a different ChirpStack version, review and adjust the script as needed before deployment.

The DS-501 supports immediate/delayed/scheduled switch and lock commands, and cancel-timer commands via Fport 2.

Fport: 2 — 0x09 0x48 (model device header)

Packet format: 09 48 [CmdCode] [Params...] All multi-byte values are big-endian (MSB first). T = delay/schedule time (uint32 BE, seconds or Unix timestamp). R = repeat flag: 0x00=once, 0x01=daily.

CmdCode Packet Bytes Description
0x00 09 48 00 01 Socket OFF immediately
0x01 09 48 01 01 Socket ON immediately
0x02 09 48 02 Unlock (remove keypad lock)
0x03 09 48 03 Lock (lock operation)
0x04 09 48 04 FF T3 T2 T1 T0 Socket OFF after delay T seconds
0x05 09 48 05 FF T3 T2 T1 T0 Socket ON after delay T seconds
0x06 09 48 06 FF T3 T2 T1 T0 R Schedule socket OFF at Unix time T (R=repeat)
0x07 09 48 07 FF T3 T2 T1 T0 R Schedule socket ON at Unix time T (R=repeat)
0x08 09 48 08 T3 T2 T1 T0 Unlock after delay T seconds
0x09 09 48 09 T3 T2 T1 T0 Lock after delay T seconds
0x0A 09 48 0A T3 T2 T1 T0 R Schedule unlock at Unix time T
0x0B 09 48 0B T3 T2 T1 T0 R Schedule lock at Unix time T
0x0C 09 48 0C 01 Cancel socket timer
0x0D 09 48 0D Cancel lock timer
0x0E 09 48 0E Query current status

// Returns a byte array to send via LoRaWAN Fport 2.
function encodeDownlink(data) {
  // data.command: 'socketOff'|'socketOn'|'unlock'|'lock'|'query'|'cancelTimer'|'cancelLockTimer'

//   encodeDownlink({command:'delayOff', delaySeconds:30}) → [0x09,0x48,0x04,0xFF,0x00,0x00,0x00,0x1E]
//   encodeDownlink({command:'scheduleOn', scheduleAt:1761177600, repeatDaily:true})
//       → [0x09,0x48,0x07,0xFF,0x69,0x0E,0x2E,0x00,0x01]
⚠️ The IP addresses (192.168.31.205 / 192.168.31.193), ChirpStack API token, Slave ID, BACnet Device ID, and devEui in the examples below are for demonstration only. Replace them with your actual gateway IP, ChirpStack API token, and device parameters.

2.1 ChirpStack MQTT Subscription

Subscribe to the MQTT topic to receive real-time uplink frames:

Application ID — 3ef9e6b9-ec54-4eda-86b8-a5fb46899f39 is the factory-default ChirpStack
application built into the gateway. Replace it with your actual application
ID if you have created a different one.

Gateway IP — 192.168.31.205 is the gateway WAN port IP shown as an
example. Replace it with your actual gateway IP address.

Device EUI — ffffff1000048920 is the EUI of the example device.
Replace it with the EUI shown in the gateway device list, or use +
as a wildcard to subscribe to all devices at once.
# Subscribe to one specific device
mosquitto_sub -h 192.168.31.205 -p 1883 \
  -u gateway -P mqtt88888888 \
  -t "application/3ef9e6b9-ec54-4eda-86b8-a5fb46899f39/device/ffffff1000048920/event/up"

# Subscribe to ALL devices on ALL applications (wildcard)
mosquitto_sub -h 192.168.31.205 -p 1883 \
  -u gateway -P mqtt88888888 \
  -t "application/+/device/+/event/up"

Example uplink payload (JSON):
