The Thread you refer to is about the LD2410, I am talking about the LD2410S
If searching for it in that Thread, there is only one Hit, and this is for the Plural of LD2410…ehm LD2410s
I guess that the misunderstanding - or I am totally blind? If so, I am really sorry, bout could you give me a hint where thats buried? Seriously, I couldn’t find anything.
Maybe those Informations are wrong, but are you sure you are driving your LD2410 with 3,3V? Having multiple 2410 as well, and when i tried it that didnt work for me.
Or do you really operate one LD2410S (not multiple LD2410s ), using the Standard Component for the LD2410? If so, do you drive it with an GPIO (sure, Data through UART)? That would indeed great News!
Hi @smartin did you find the way to make it work in esphome? I got the same problem as you tried with several configurations and none of them are working.
Unfortunately not.
I found a custom component in (I guess) Chinese that aimed to make the 2410S usable and asked about the current state, but didn’t get a response.
As I couldn’t find any sign it might work I didn’t buy them, though.
Well, I bought 5 of these before I knew it wasn’t supported by ESPHome yet. Now I went looking for how to use it and found this thread. The good news is that it isn’t completely useless, though! The LD2410S has a “OT2” pin that is a simple IO pin, pulled high when presence is detected and low when it’s not. So I connected just that pin to my ESP32 like a regular binary sensor:
And it works pretty well! I’m stuck with the configuration it comes with out of the box and all I get is this one binary sensor, but it has been doing a good job in my tests so far. Now I’m getting a UART to USB adapter to try and run their config tool, described in the documentation here: HLK-LD2410S Lower power consumption - Google Drive
Mostly to play with it though, since I’ll still be stuck with just the one sensor. I hope there’s better support for it in ESPHome soon; I’d love to be able to get all its data and hopefully be able to set up multiple zones within a room.
Thanks for sharing your Experience, appreciate it!
Yeah i noticed the Hi/Lo Output, great to know that it is working in Default settings out of the Box!
But well, beeing able to control and tune it with ESPhome is of course premium. Setting it externally might be a doable Workaround. However, yet i am not convinced to go that Way.
My Experience from LD2410B is, that the performance and correct detection can significantly be improved.
Can you tell me how you drive your LD2410S? Does it work only using an GPIO set to High (=3,3V)? Maybe will go that Route then as well, as i want a Device i can turn on/off by Request.
