Hi,
Thanks for the recommendations guys.
Similar to the GP2Y0A60SZ, I think I’m going to take a look at using VL53L0X and customising WLED source to react to sensor changes on board so that I don’t have to do a round trip to HA with sensor state, just to send command back to nodeMcu to turn on lightstrip.
I’m hoping to be able to use 4 VL53L0X - two at top of staircase and two at bottom which will allow me to detect when someone has entered + exited the staircase based on direction/time of sensors detecting a change and to store number of people on stairs state for turning on/off lightstrip.
