So I am looking to get precense detection in my living room. I think I want mmwave as I do want to detect people that are sitting on the couch for example. And I saw most don't have a large distance and angle as my living room/kitchen is 8m by 12m(in an L shape) so most with a 4-6m detection distance are not enough. Also regarding the price I am looking at esphome with a hi-link sensor. But I would like to get some recommendations if I should get a LD2420 or LD2410. Some say the 2420 can't detect a stationary target but the 2410 has less range(6m vs 8m). So I thought place 2 LD2420's for 120 degree 8m coverage in the corner of the L with a esp8266. Would this work for stationary targets? (it doesn't have to be able to differentiate between the two just not be like a infrared motion sensor). Also if you have done this and have found problems or something to share please do so. Thanks for your sharing experience with one or both of the sensors and your knowledge about this topic.
