MSR-2 mmWave Multisensor (LD2410B)

Excellent little dude

Wanted something reliable, configurable, easy to implement with Home Assistant. Got exactly that. These things report more sensors into HA than I even know what to do with, and are so fully configurable I had to have Claude help me do it. ^_^ But now I've got fairly faultless presence and motion detection in two rooms and, importantly, all the sensor specificity to tell apart what I need to tell apart, and room-level calibration that works for the type of presence and contours of the room I'm working with.

My sensors arrived well packaged and I immediately put them to good use in the living room and kitchen of my house. Using a Home Assistant automation I wrote to trigger the onboard led, I was able to quickly calibrate the three detection zones. So far so good.

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
