mmWave Wars: one sensor (module) to rule them all

jonwilliams · January 11, 2023, 8:16am

Hi, Where can I get the phone app from?

blakadder · January 11, 2023, 8:51am

Latest HLKRadarTool can be found here

MrBlowfish · January 12, 2023, 10:26am

Only for Android, and only as a sideloaded app. for now.

Maco65 · January 12, 2023, 12:15pm

There isl HLKRadarTool for iPhone (from App Store):

Do you mind sharing links to what you got?

I found a 5 pin JST 1.25mm on aliexpress but I’m not sure what you did on the LD2410 side.
Mine has 5 pins but it doesn’t look like yours.

Thanks

Maco65 · January 13, 2023, 6:39pm

I also used JST GH 1,25 mm 5 PIN connector. Different then on the picture from NorbertReinhold - i just used female connector and pushed it into existing 5 pins on the module.

hello, I understand correctly, you changed the module as in my picture to LD1115h and does it work for you? does not detect the presence of .

reversebias · January 20, 2023, 11:34pm

Thanks for the thread! So I use KS-811 switches at home:

Which only have indicators on the left side and a blank plastic panel on the right. With a bit of modification to the internal plastic ribs:

There’s enough room to mount a LD2410 right behind that blank panel:

Powered by the 5V internal rail (plenty of spare current as I’m not using all 3 relays in these switches), and mounted above the power entry to the front PCB. Wired up the hardware UART of the ESP8266, working great with the @amandel custom component. Thanks! There’s actually even enough room to angle the module slightly, to aim the module when the light switch is in the corner of the room.

FeromonDE · February 2, 2023, 7:24pm

Can you share your .yaml for esp8266?

reversebias · February 3, 2023, 5:56am

I’m using this repository, note the sample .yaml. Key thing would be to use the hardware UART on the esp8266. Do you specifically want a config for the ks811 switches?

FeromonDE · February 3, 2023, 9:07am

But this repo for ESP32 only, that’s why I asked.

LoopOn · February 3, 2023, 8:23pm

Switching to ESP8266 shouldn’t be difficult. Replace the esp32: block with the information in here ESP8266 Platform — ESPHome.

Make sure to select the correct UART pins for your board.

Thanks for the link @FeromonDE, I’d also got these compilation errors for esp8266, but hadn’t seen that particular issue thread. At the time I assumed it must have been an issue with my out-of-date esphome installation, so I didn’t put any thought into it.

I’ve uploaded the changes I made here, simply removing the unused ESP_LOGD_HEX functions that were causing the compliation errors:

Who know, what this Setting mean?

Appeared after firmware and App update.

Peter_Mattisson · February 9, 2023, 12:25am

Thinking about ordering a few of these, how did it go for you with these?
And is it possible to use ESPresense with these (get the presence, not only motion)

MrBlowfish · February 9, 2023, 9:06am

Works perfcetly fine with ESP32.
HA interface:

Settings (distance, sensitivity) are possible from the ESP web server. I can’t connect to it over BT, but that issue is probably on my end. Using the repo from amandel (LD2410C is the same as 2410B just in a different form).

bachoo786 · February 10, 2023, 4:17pm

hey guys so I have just come across this thread and I can see something beautiful going on here. May I just ask what is the best mmWave sensor I can buy and the best board to run it on? i.e. ESP8266 or ESP32? thanks.

Holdestmade · February 10, 2023, 4:19pm

If you have Bluetooth setup on your HA, 2022.3 has support for directly integrating a HLK-LD2410B over Bluetooth. I’ve tried it and it works great, no need for an esp32 or esp8266.

bachoo786 · February 10, 2023, 4:33pm

I have bluetooth setup however my bluetooth node is meters away (on the first floor) from where I would want to have my mmWave sensor (on the ground floor). Would it still work reliably?
