I think i’ve got zout working now after some trial and error.
I think this has something to do with sensor that prioritise the more active target (fan) when the other target is static/not moving. Hopefully this gets fixed on the next hlk sensor update.

That is the same thing I am experiencing which makes this sensor problematic for use with multiple zones with the current HiLink firmware. I have setup 3 zones and if there is a person in Zone 1 and another person in Zone 2, the sensor will lose track of the one moving less and so will clear the presence of one of the Zones and if that is setup for the lights, then the lights will turn off.

I noticed that the LD2450 clears the Zone Presence immediately when it doesn’t detect a target. When there is little movement, it seems to clear the presence and then detect it again in a few seconds. Adding a configurable delay to when the presence is cleared could resolve this issue.
The following code should allow the timeout for each zone to be configured and set:

It’s a cool feature, Gus, and we’ll try to incorporate it into the firmware.

I was doing this just now, but your solution is way better than mine.

I just saw @screek-workshop post on static detection with different mmwave sensor on the facebook group.

Hi there, I have looked all over and even asked Hi-Link with no luck. Could you tell me which connecter type you used here?

It is a 1.5mm 4pin connector.

When it comes to decimals, I think the conversion to float is necessary and good.
Great job, and putting the angle calculations into it is a great idea!
But the final code for the angle aspect seems to be truncated, unfortunately.
thank you.
Yes, we have also changed the pronouncement of sharing diy products in ebay, this radar is only suitable as a moving or micro-motion target tracking radar, it has no static detection.
The comments are wrong, but the code is there. I needed to move the code up because I ended up using it to validate that the target is within the boundary area.
Starts here:
float p1_a = (p1_x);

Thanks, this is a great idea.
I couldn’t do the math using int16, so I converted it to a float. Maybe it’s possible to improve the code.

Does the LD1151H also has multi target and possible to add exclusion zones?

Thank you for confirming. It looked like that would be the right one but there customer support told me it was not.
ferbulous:
LD1151H
The LD1151H is not a tracking radar, it’s just a longer range ld2410-like radar with what appear to be certain algorithmic improvements.
The 2450 has two sets of interfaces, the simplest of which is for the ZH1.5, and the other, more complex (lots of pins, some of which are obviously intended for customized functionality). are of a different specification.
Generally speaking, ZH1.5 is the best for DIY connections.
We can be relatively sure of this because we’ve used over 600 of them.
We have merged athua’s delayed off code to make this delayed shutdown feature easily available to everyone.
https://www.reddit.com/r/screekworkshop/comments/167tjxf/2a_beta_firmware_update_v230902_beta/
Next we would like to merge walberjunior’s angle and movement direction description code.
The code has also been updated to a beta version on github.
As a movement tracking radar the LD2450 offers new possibilities. It’s great that for once DIY is ahead of commercial products.
