I've just checked. Using the cam directly this should work for motion detection. You might want to try http instead of https.
https://your.ip.address/api.cgi?cmd=GetMdState&user=admin&password=your_password

and this for smart detection
https://your.ip.address/api.cgi?cmd=GetAiState&user=admin&password=your_password

Then you need to extract the appropriate fields fro the json reply like shown here

I have had also issues with reolink_dev. I went away from it and I'm using the generic camera integration for the video stream and the HA rest api for the alarms. This works great. See here how to do this: https://community.home-assistant.io/t/reolink-nvr-to-home-assistant-issue/430491
(tteck's answer). He is using a NVR though. You should also be able to do the same using your camera directly.
