[Idea] Webserver?
Never been a fan of poking devices via telnet constantly.
What about grabbing a busybox binary with httpd compiled and using cgi? e.g
#!/bin/sh
while IFS= read -r -d '&' KEYVAL && [[ -n "$KEYVAL" ]]; do
case ${KEYVAL%=*} in
prop) PROP=${KEYVAL#*=} ;;
esac
done <<END
$(echo "${QUERY_STRING}&")
END
if [ -z "$PROP" ]; then
PROP="full"
fi
RES=`agetprop "$PROP"`
IS_JSON=`echo "$RES" | grep -c "^{"`
if [[ "$IS_JSON" -gt 0 ]]; then
printf "Content-type: application/json\n\n"
else
printf "Content-type: text/plain\n\n"
fi
echo "$RES"
x@x:[~]$ curl -v "http://x.x.x.x/cgi-bin/get_prop.sh?prop=ro.sys.fw_ver"

Could be nice for your ptz control stuff, getting uptime, sdcard usage, etc etc.
It is good but need a lot of efforts.
I will add features one by one.
I studied yi-hack-mstar before. It is a good example.

Hi, is this idea in progress?
I added many functions via static binary, such as crontab, sshd, nginx fcgiwrap and php, but I don't know what the command is to move ptz for example.
Can you help me or send me the web page you created?
found /data/bin/mi_motor
I created a guide for setting nginx with cgi and took your getprop page. thank you

Please reference to another solution, using miio socket. There are two approaches.

Using miio socket, you can control/access G3 to set/get more settings of G3.
Thanks for the reply, I didn't know this method with mii socket-mqtt. I tried it but I don't need to have the mqtt messages and it doesn't seem to capture all the messages.
My project on git whith nodered with post requests works best for me.
I was just looking for a command to move the camera and "/data/bin/mi_motor" works fine. Thank you
