hi , i hv connected hlk-ld2410b with esphome. its working but i am facing an issue that after detecting presence, if i start watching movie or reading an book so sensor starting losing still energy after few mints and after seconds it shows no presence and my lights turn off. i hv tried all settings testing on 5v and 12v but no luck
Did you check it on the android app ?
I’m still testing it and I notice the same thing. But if I position my self in front of the radar than still energy doesnt drop.
yes i hv tried on andriod app but same result. … how could i set my self always infront of radar. i hv installed it on roof ceiling… but yes i hv tried one module on wall but still same result. i hv to move constantly otherwise it ill stop detecting…
I don’t know exactly. Maybe you should try to adjust still settings for gx and find ones that works best. Maybe the problem is in a firmware. You can upgrade firmware using app to 2.0 to see will that help. You can find instructions on line on how to upgrade firmware.
firmware is upgraded. sory i dont understand what mean by gx
Check this.
As I understand you can manually adjust sensitivity for move and still. If you are using esphome firmware you probably can do it in home assistant.
Maybe I’m wrong but I think that the trick is to adjust sensitivity on the sensor to get desired data.
I found out that defaults are working for distance up to 2.5 meters or more than 3 but only if you are standing right in front of the sensor.
thanks for replaying i hv tried still threshold on all levels but still same… this sensor is also working as PIR motion sensor not working as presence detector. it stop detecting if u stay still for some time … i also tried with esphome… direct output pin from ld2410b but problem is same
Well try to reposition the sensor. I read somewhere that it has 60 degree detection angle. Sensor is really small so its easy to miss an angle.
Try to restore it to default detection values.
hmmm let me try but i hv already installed 10 sensors on different location and different angels with different settings
I use it still on a testing ground. I glue it with a double side tape on a sponge that comes with esp32 board and find out after a few days that it doesnt stay on 90 degree angle. It was a bit offset but enough to give different readings.

hi,
i hv find that there is some delay in sensor’s out put when it detects something , like if we install in a room and someone came and open the door, most of the time it take some time (1-2 seconds or less than a second) for turning on output on rx tx, and even its own output pin specially it happened when u install it in an open area or hall (cus if u open the door it take sometime automatically and got big movement but if u came in open space detation range it ill take time to turning on ). i am facing problem that if someone came in speed and enters in my detecting area it turn on lights with some delay and that person have to wait for second in dark, how to solve that issue cus it make really bad impact in my automation… (i hv to tell everyone please walk slowly if u dont want to stay in dark )

Maybe the problem is in a switch especially if you are using something like tuya wifi switches that uses cloud. Does your switches using local control?
I didn’t notice this behavior in ld2410 sensor.
This usually happens with some pir sensors.
I have the same kind of readings from the sensor. When i move it is raising the still energy but then, when i stay still, it drops. Keep your app on the phone open, and check what is the minimum energy that it shows when you are still. Also important is on which gate it shows the minimum.
It has 8 gates and initially, i didn’t realize what do they mean. I though that it is angle but it is in reality distance from the sensor. my sofa is about 3.5 meters from my tv so when i am on the sofa, i get energy on gates 4,5 and 6. Staying completely still, drops the energy to about 9-12. What i have done is that i set the sensitivity on those gates to 8. When i leave the room, the energy on those gates is about 4-5. Setting the sensitivity correctly is very important. Check it when still and when away from the room.
Also another important factor is the time in which the sensor will report no presence. I have this to 60 seconds. The way that it works, is that even if the energy falls below the sensitivity, the sensor will still report presence for the time that it’s set up (60 sec in my case). Set this on a high value as within this time, it is probable that you will move and increase the energy above the sensitivity so your lights will stay on.
Another trick i can mention, is that you can also use the still distance sensor. It reports the distance from the sensor that presence is detected. Check this value as well as it maybe sometimes better to add it as a condition to your automation. For example, If still energy is below 9 and the still distance is above 400cm then turn the lights off.
Setting it up is not easy as it requires trial and error but when you figure it out it works pretty good.
Hope this helps
Kind Regards
