Update. mmWave works through the glass great!

In fact it sees me through the wall before I even enter the bathroom now. Super cool! Got two and set on up in my office

thats the goal! It’s a glass door though, does that matter?

Also! I was able to use this to make my PIR sensor presence detection more accurate

before it would not see me in my shower and think im not there. Now that automation only triggers if the bathroom is also ‘dry’
