ERROR (MainThread) [homeassistant.config_entries] Error occurred loading configuration flow for integration aqara_camera: cannot import name 'Platform' from 'homeassistant.const' (/usr/src/homeassistant/homeassistant/const.py)

Hi, thank you for your integration! README notice that after camera reboot, rtsp url is change. But Alex WebRTC integration allows to use camera entity instead of rtsp url, so maybe there is a way, to use it? I tried to use entity instead of url, and for the first time it worked, but after reboot, webrtc card was unable to get stream from the entity. Just giving you a food for thought, I understand that currently it's just a draft. Additionaly, it would be great if stream would support for the rectangles of the detected objects, like it in the aqara app stream, or stream, passing through homekit integration. And currently, ptz control move camera very slightly, it would be great to have a way to ajust steps.

After following the instructions, I now have telnet access, but in HA I keep getting failed to connect errors.

Firmware the unit shipped with is 3.3.2_0001.0004 and I haven't updated. Do we need to be on the specific firmware versions you list or all is fine as long as we were able to apply the telnet hack?

Also, anyone know how to "upgrade" to a specific firmware version? Say 3.3.2_0019.0004 or 3.3.4_0007.0004 which is in the supported versions notes.

Hi there

Thanks so much for the plugin. I'm just struggling to get it going, I'm getting these 2 errors:

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"

Could be nice for your ptz control stuff, getting uptime, sdcard usage, etc etc.
