Nice to see what you guys are doing. I have integrated Zoneminder alerts with HA via AppDaemon. Working nice, I am using it to send alert text messages with image from the object detection provided by ZM-ES. Take a look at this discussion thread:
I am now working to enable GPU acceleration via OpenCV + Yolo3. I am running on unraid using the dlandon/zoneminder docker container.
Anxious to hear if anyone is running with CUDA acceleration.
FWIW
