This is a changelog topic for the Howen protocol. The list of supported devices Howen Hero-MA80-04 Howen Hero-MA80-08 Howen Hero-MC30-01 Howen Hero-MC30-02 Howen Hero-ME30-04 Howen Hero-ME31-04 Howen Hero-ME31-08 Howen Hero-ME32-04 Howen Hero-ME32-08 Howen Hero-ME40-02 Howen Hero-ME40-04 Howen Hero-ME41-02 Howen Hero-ME41-04

Parameter disk.type was added, and parameter disk.id type was changed from string to number, with appropriate parsing.

howen protocol has been changed, fixed gsm.signal.level parameter parsing

howen protocol updated: fixed negative latitude calculation when its degree is about zero

Added VIDEO download and snapshot (photo) taking . You can request videos and photos on the MEDIA tab, which becomes available when you enable the experimental functionality in your account settings. Or using the "request_video" and "take_photo" device commands - they will be sent and repeated up to 3 times until device finish media file upload. Those commands results will contain all information about uploaded media file. When you click on the video download button, an additional window will appear in which you have to select: Camera channel as a video source Indicate the time that will serve as the beginning of the video Duration of the video All necessary information for the video file is recorded in logs and messages:

Howen protocol has been changed, fixed Status Data part of protocol parsing

Howen protocol has been updated, added events 41 Trip started , 43 Trip ended

Howen protocol has been updated, added Video parameters , Video main stream , Video sub stream settings

Howen protocol has been updated, added iButton status and Overtime parking event parsing

Video live streaming from Howen devices is now supported in both H.264 and H.265 (HEVC) codecs, with automatic transcoding to H.264 during streaming.

howen protocol update: added new standard video commands playback_video and video_timeline . The playback_video command performs almost the same function as request_video , except its result is an HLS live stream URL, allowing you to view the historical video almost immediately, without waiting for the full file upload. The video_timeline command enables you to retrieve time intervals with video recordings stored on the disk, which are available for download/playback.

[Changelog] howen protocol

namo

Howen protocol updated: so that Fuel Consumption Status field wouldn't cause parsing error.

namo

namo Howen protocol updated: Fuel Consumption Status parameters are integrated:

field fuel consumption is stored into flespi parameter fuel.sensor.value
field balance fuel is stored into flespi parameter fuel.balance.value

YuryAheichyk

YuryAheichyk changes applied, the response field of the Download event media command result have an array of objects now

bird

Bugfix in DST offset calculation: the dst.offset setting value was incorrectly treated as a 30-minute multiplier instead of an enumerated code (0→15min, 1→30min, 2→45min, 3→60min). Devices using DST offset other than 30 minutes were getting incorrect UTC timestamps.

bird

New setting fields iccid and imei added to the Info setting, parsed from the 0x1001 registration message.

bird

New parameters for cement mixer telemetry: drum.forward.revolutions, drum.reverse.revolutions, drum.mixing.duration
New parameters for module extension information: temperature.sensor.operating.time, position.speed.source, water.flow.status
New parameters for integrated water flow statistics alarm (ec=773): water.flow.pulse.count, water.flow.volume

bird

New parameters for load info (Group 2): trailer.connected.status, trailer.voltage, trailer.cargo.weight, total.vehicle.weight.

bird

Bugfix: det.ch for Input trigger and Emergency alarm events (event types 4 and 5) no longer incorrectly stored as video.channel
New parameters event.trigger.input and event.trigger.enum added for Input trigger and Emergency alarm events, representing the triggered IO input number and IOSET alarm type code respectively

baja

New device type added: Howen Hero-MC30-02

bird

Subscription requests (0x4040, 0x4050) now request Group 2 content status in addition to Group 1. Devices with Group 2 peripherals (cement mixer, load sensor, module extension) will start reporting this data after reconnection.

bird

Fixed parsing of water flow alarm (ec=773) — water.flow.pulse.count and water.flow.volume parameters now populate correctly.

namo

Howen protocol is updated: added utczone field for servers' settings into the Central Server setting, Connectivity tab.

bird

New setting added: JTBASE (Industry Standard), Connectivity tab. Configures Center 1 / Center 2 protocol type selection, per-center GPS report intervals, GNSS positioning mode, and identity fields.

bird

New parameters added for People counting (passenger counting) alarm events: passengers.in.count, passengers.out.count, passengers.sensor.mask, bus.counter.passengers.

bird

New command get_calendar added to request calendar with dates that have available recordings

bird

New setting added: Version Information, Info tab

bird

Fixed parsing of alarm media file names in download_event_media:

alarm snapshots and recordings whose file name omits the AI type field are now parsed instead of failing the download
created timestamp is now correct for alarm types 66 and 67 (previously a small incorrect value was reported)

bird

New streamtype property added to request_video and playback_video commands, selecting sub or main stream for the recording playback request. Defaults to main stream.

YuryAheichyk

New command Request log added: the device searches its log files within the requested Search from - Search to period and uploads them to flespi. FTP Password must be set in the device configuration.

YuryAheichyk

WebRTC streams
The mediastream parameter of the video commands accepts webrtc alongside hls and flv, for low-latency live viewing.

Intercom request from the device
New parameter intercom.request.event, registered when the driver presses the intercom button (input alarm trigger 17) and waits for a call back.

New settings
FTP Server - the address, port, credentials and state port of the FTP server the device uploads to.
Storage - the role of each of the six disks (none, main video, mirror, alternative), their capacity, alarm pre-recording and post-recording duration, and the video protection time.
