This is a changelog topic for the Howen protocol. The list of supported devices Howen Hero-ME31-04 Howen Hero-ME31-08 Howen Hero-ME31-12 Howen Hero-ME32-04 Howen Hero-ME32-08 Howen Hero-ME40-02 Howen Hero-ME41-02 Howen Hero-ME41-04 Howen Hero-MA80-04 Howen Hero-MA80-08 Howen Hero-ME30-04 Howen Hero-ME40-04

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.

YuryAheichyk

Added Request blackbox data command

YuryAheichyk

The ai.alarm.type and ai.alarm.type.name parameters will be removed on 15-Jan-2025.
Use dsm.event.enum, dsm.event.name, adas.event.enum, adas.event.name parameters instead.

YuryAheichyk

YuryAheichyk changes applied, ai.alarm.type and ai.alarm.type.name parameters removed

YuryAheichyk

Added Download event media command

Parameter file.name now has only the name of the file, a full path with file name registering to file.path parameter

YuryAheichyk

Automatic event media request option has been added to the device configuration to manage automatic download of event media from the device. When this option is enabled, the Download event media command will be sent to the device to receive media files.

YuryAheichyk

Added Visible alarm video/snapshot file type option for download_event_media command

YuryAheichyk

Howen protocol updated, when the Automatic event media request option is enabled, the download_event_media command is sent with the file type 9 - Visible alarm video/snapshot

YuryAheichyk

Improved Clock setting, added DST adjustment

2 stage change in parsing indexed parameters for analog inputs: ain.1, ain.2, ain.3 and ain.4
The updated documentation says that ain.1 is the voltage of the device battery, and ain.2 is the voltage of the device's supercapacitor.
First stage of parameter renaming:
device.battery.voltage is stored together with ain.1
device.supercapacitor.voltage is stored with multiplier 0.001 together with ain.2 (original multiplier is 0.01)
First stage lasts till November 17th. Users must switch from using ain.1 and ain.2. On the second stage ain.1 and ain.2 will be used together with ain.3 and ain.4

baja

baja important note about scheduled update. Parameter name device.battery.voltage is incorrect, because it shows not the device battery voltage, but external voltage (usually taken from vehicle battery, but not guaranteed). So this parameter is to be stored as external.powersource.voltage
The same logic relates to parameter external.battery.voltage which is taken from Blackbox report - it is not actually the battery voltage, but powersource voltage.

So external.battery.voltage from Blackbox will be renamed to external.powersource.voltage
and device.battery.voltage will be renamed to external.powersource.voltage
both parameters are registered for now, outdated names will be removed on Monday, November 24th

baja

baja second stage of ain-related parameters parsing change
now ain.1 has the same value as ain.3
and ain.2 has the same value as ain.4
this lasts for 2 weeks, users must switch from using ain.3 and ain.4 to ain1 and ain2. In a week the parameters ain.3 and ain.4 will be removed. Together with them incorrect naming external.battery.voltage will be removed.
