Use Xiaomi Yi Ants Camera 2 (EU) in combination with ioBroker to send motion or baby cry detections (baby monitor) as videos to Telegram.

this is based on the out dated yi-hack-v2 project (http://github.com/niclet/yi-hack-v2.git)

Purpose

This project is a collection of scripts and binaries file to use your Xiaomi Yi Ants Camera 2 in combination with ioBroker.

This camera has the default following features :

wifi
motion detection : a video file is generated if a motion have been detected in the last 60 seconds.
baby cry detection : a video file is generated if a baby cry have been detected in the last 60 seconds.
send video data over the network on Chinese servers in the cloud to allow people to view camera data from their smartphone wherever they are.
setup thanks to a smartphone application.
local video storage on a SD card
no RTSP server

This hack includes :

Base firmware : 2.1.1_20171024151200 EU (Check with app if your device has the same firmware, if not replace)
Telnet server activated
FTP server activated

Installation on the YI camera

The memory card must stay in the camera ! If you remove it, the camera will start without using the hack.

Prepare the memory card

Clone this repository on a computer :

git clone https://github.com/bompo/yi-hack-v2

Then, format a micro SD card in fat32 (vfat) format and copy the content of the yi-hack-v2/sd/ folder at the root of your memory card.

The memory card will so contain :

home.bin : the official firmware file compliant with EU model
test : the folder which contains the hack scripts and binaries

Replace your wifi settings in test/wpa_supplicant.conf and your firmware if needed.

Start the camera

If plugged, unplug the Yi camera
Insert the memory card in the Yi camera
Plug the Yi camera
Follow instructions to pair with your mobile app. This is only needed the first time.

The camera will start. The led will indicate the current status :

yellow : camera startup
blue blinking : network configuration in progress (connect to wifi, set up the IP address)
blue : network configuration is OK. Camera is ready to use.

Use the camera

FTP server

The FTP server is on port 21.

No authentication is needed, you can use anonymous user.

Use with ioBroker

Simply check the FTP Server for file changes in:

ftp://IP_ADDRESS/tmp/eventd/event_child_cry.mp4 to check for baby cry

ftp://IP_ADDRESS/tmp/eventd/event_motion.mp4 to check for movements

See the script in iobroker/SendMessageToTelegramIfBabyCryDetected.js to check how it can be used to send baby cries to telegram with ioBroker. You need to install the Telegram Adapter and activate a bot as well.

You need the following npm modules enabled: jsftp, fs, path

      startup_official.sh      This script is called from factory_test.sh when OFFICIAL startup is activated
  wpa_supplicant.conf          This config file must be correctly filled to connect the camera to your wifi network when RTSP feature is enabled
  yi-hack-v2.cfg               This config file lets you tune up various behaviors

factory_test.sh

Telnet server

The telnet server is on port 23.

No authentication is needed, default user is root.

RTSP server

To activate the RTSP server, you need to modify test/yi-hack-v2.cfg and uncomment the line YI_HACK_STARTUP_MODE=MODIFIED

You must also modify test/wpa_supplicant.conf to be compliant with your own wifi network.

Please note that when you activate RTSP server, you can't use your mobile app anymore.

During camera startup, the led will indicate the current status :

yellow : camera startup
blue blinking : network configuration in progress (connect to wifi, set up the IP address)
blue : network configuration is OK. Camera is ready to use.
red : network configuration is KO. You should check your test/wpa_supplicant.conf file.

Main stream is available from rtsp://<IP>/stream1

A secondary MJPEG stream is also available from rtsp://<IP>/stream2

Following hostmit suggestion, you can now use test/v2/scripts/capture.sh to capture a single frame as a JPG file.

How can I know which is the version of a firmware 'home.bin' file ?

Just do : strings home.bin | grep YUNYI_VERSION. Example :

$ strings home.bin | grep YUNYI_VERSION
YUNYI_VERSION=2.1.1_20160429113900
