[Changelog] meitrack protocol

namo

Meitrack protocol is updated: parsing of Wifi MAC addresses is refactored.

shal

New event code mappings added for multiple Meitrack device families:

T711L: Event codes now map to engine.ignition.status, movement.status, sleep.mode.status, overspeeding.event, harsh.cornering.event, harsh.braking.event, harsh.acceleration.event, crash.event, ibutton.connected.status, idle.event, fatigue.driving.status
TC68L: Event codes now map to geofence.status, towing.event, power.on.status, engine.ignition.status, movement.status, harsh.braking.event, harsh.acceleration.event, idle.event, fatigue.driving.status
TC68SL/TS299L: Event codes now map to geofence.status, towing.event, power.on.status
T322X/MVT100/MVT340: Event codes now map to engine.ignition.status, movement.status, sleep.mode.status, overspeeding.event, harsh.cornering.event, geofence.status, towing.event, power.on.status
MVT600/T1/T333/T32/T633L: Same mappings as T322X family
MVT380/MVT800: Same mappings as T322X family

shal

Comprehensive event code parsing update for meitrack protocol:

T711L: Complete coverage (53 codes) including door, inputs, geofence, temperature, fuel, security, outputs, BLE, maintenance
TC68L: Added SOS, speeding, sleep, RPM, engine temperature, speed recovery, maintenance
T322X/MVT600/MVT380: Added SOS, door, inputs, GSM jamming, temperature, fuel, security, fall/install/drop, maintenance
T633L: Added SOS, door, inputs 4-9, temperature, fuel, speed recovery

shal

T633L: Added event codes for impact detection (78) and sharp turns (90/91)

baja

baja CCE ID 0x4C bug fixed: incorrect multiplier applied. Now values for indexed ain, batter.voltage and external.powersource.voltage are stored in volts correctly.

baja

New parameters x.acceleration, y.acceleration, z.acceleration added (CCE packet parameter 0xFEF5)

shal

Fixed T399 series event code mapping: now populates engine.ignition.status, sos.alarm and other standardized event params for t399l/t399y41.

shal

A number of changed across a range of Meitrack devices:

New parameters for T711L CCE messages: engine.ignition.status derived from system flag (0x1C) ACC status and event codes 1/9/144/145 via parameter 0x01
New parameters for T399L CCE messages: engine.ignition.status, alarm.mode.status, vibration.status, movement.status, external.powersource.status, battery.charging.status, sleep.mode.status derived from system flag (0x1C) bitfield
Fixed missing event code mappings: T633L event code 9 (Input 1 Inactive), MVT600 event codes 133/134 (Idle Overtime/Recovery)
Fixed A10 (Real-Time Location Query) command acknowledgment — device response with event code 34 is now correctly recognized as command result. Previously A10 commands showed executed=false despite device responding. Enabled CCE event code mapping for T399 series devices.
Added support for event code 37 (RFID).

shal

New parameter engine.ignition.status added to periodic CCE messages for T633L, MVT600, T1, T333, T32, T322X, MVT100, MVT340, MVT380, MVT800 devices.

bird

New ble.beacons parameter added for T399L: BLE beacon A/B (CCE IDs 0xFE71/0xFE72), temperature/humidity sensor (0xFE73), and BLE device alerts (0xFE70).

bird

Fixed BLE beacon parsing crash when multiple beacons are reported in a single CCE FE71/FE72 parameter for T399L devices

bird

New parameter dead.reckoning.state added for CCE messages

bird

New parameters for T633L and other CCE devices: geofence.id (wide encoding), engine.ignition.off.duration, trip.fuel.consumed.level.
New event codes supported for T633L: photo, GSM jamming on/off, output 1/2 active/inactive, rollover, ignition on/off.

bird

Event code support added for Meitrack MD600 and Meitrack MD833H: the full documented event code table is now mapped. These devices previously registered event codes without any parameter mapping.

Newly registered parameters by feature group:

Video and storage: video.loss.alarm, storage.media.malfunction, storage.full.status (new parameter)
ADAS: adas.collision.warning.event, adas.pedestrian.event, adas.lane.departure.event, adas.distance.event, adas.blindspot.event, adas.blindspot.side, adas.event.enum, adas.event.name
DMS: dsm.driver.phone.event, dsm.smoking.event, dsm.fatigue.event, dsm.yawning.event, dsm.distraction.event, dsm.driver.missing.event, dsm.camera.blocked.event, dsm.seatbelt.event, dsm.event.enum, dsm.event.name
Inputs, outputs and device status: din, dout, engine.ignition.status, movement.status, geofence.status, sleep.mode.status, gnss.signal.status, external.powersource.status, fatigue.driving.status, ibutton.connected.status, plus the corresponding alarm and event parameters (SOS, crash, towing, fuel, temperature, harsh driving, idle, overspeeding, reboot, maintenance, BLE).

bird

CE0 bidirectional transparent transmission packets are now parsed for Meitrack devices. The transparent serial payload is registered as payload.hex and, when the data is valid UTF-8, also as payload.text. Each packet's device receive time is registered as event.timestamp.

bird

Event codes for Input 2 and Input 3 activation now register the din parameter on T633L, MVT600, T1, T333, T32, MVT380, MVT800, T322X, MVT100 and MVT340 devices: din.2 for codes 2/10 (Input 2 active/inactive) and din.3 for codes 3/11 (Input 3 active/inactive).

These event codes also register door.open.status during a transition period. On 2026-09-21 that parameter will be removed from these event codes - integrations reading it should move to din.2/din.3.

bird

Added vehicle battery voltage, engine coolant level, trip fuel consumption, and overspeed summary data to CCE/CFF reports.

bird

Fixed event-code parameter mapping for MT90, T311 and T355 AAA reports.
Removed incorrectly calculated external.powersource.voltage from MT90 AAA reports.

YuryAheichyk

New start_audiostream command for MDVR models with three modes: listening, intercom (default) and broadcast. The viewer's voice from the live stream is played on the device. Both G.726 and G.711A audio are supported.
New server setting for MDVR devices. The device_info setting now also works for them.
