 ## Future improvements
+- [x] Switch to MQTT prefix
+- [x] Add last will and availability for MQTT
+- [ ] Add ability to turn detection on and off via MQTT
 - [ ] Add a max size for motion and objects
 - [ ] Filter out detected objects that are not the right size
 - [ ] Merge bounding boxes that span multiple regions
+- [ ] Switch to a config file
+- [ ] Allow motion regions to be different than object detection regions
 - [x] Change color of bounding box if motion detected
