Request for LD-2461 Component for ESPHOME

@TillFleisch
Thanks for great contribution on the LD-2450 Component, and it works great and seamlessly.

To be able to track more Targets within a region, can you recommend adding more than one LD2450 Modules in an Array with different frequency and Timings?

In such a case, can we track 3 Targets each 3 Target X 3 Modules i.e. upto 9 targets in the same 5 Meter scale region?

Also Please extend your component for LD-2461 as well.

Thanks in Advance!

2 overlapping modules likely would result in issues. Either from a HW point of view (interference) or from the software side. To the best of my knowledge there is no way to tell the sensor to track a specific person/are. Therefore, there is no way to guarantee that different sensors track different persons. Furthermore, occlusion will be a major problem, with which the LD2450 seems to struggle at times.

I don't understand what you mean by frequency and timing, can you elaborate? As far as my understanding goes, these are not configurable options on the LD2450.

Also Please extend your component for LD-2461 as well.

Not anytime soon. I got the LD2450s because there were cheap and I wanted to play around with them. They are an acceptable solution for my use-case, therefore I am not incentivized to invest more money/time. If there is a need for this feature someone can fork this repository (and open a PR).

Thanks for taking time to respond.

We can run 2 LD2450 Radars side by side in 2 different Frequency settings without interfering each other, but The problem would be to uniquely identify different targets on each of them.
