Only bad thing is I didn't know these existed before. Need better marketing hahah
Upsets me that I didn't know these were a thing. Completely changed my automations. The level of accuracy and how much you can customize to your room size is insane when coming from regular motion sensors. Thank you

Super MSR-2 Sensor
These are great multi-sensors. I have several integrated into Home Assistant to monitor each room. I like the fact that they are so small and reliable.

easy to install. Great addition to Home Automation a must have
Just bought my 3rd and 4th MSR2. You really need them in any room where you spend time. walk in a room and lights turn on during a time frame. walk out and they turn off. Such a small footprint.
