You video's are pretty clear, not too slow and not too fast. And when it's a bit too fast than it's less annoying to scrol a fragment back. But hihi... it must be your Italian vibe and accent.... I can't resist the urge to imitate your .... ' and.., that's it'. Funny repeating soundbite, I mean this in positive sense :D. Unfortunately I fail in my imitation, lol. Maybe you need to create your own home assistant audio notifications. :D :D and that's it.

Thanks for an inspirational video! Do you know if it's possible to use the HLK-LD2410B instead?
@fixtse. Місяць тому
Hi, thank you 😁🙌, Unfortunately no, the LD2410 it's a whole different sensor, most of the features are built into the sensors firmware, like the zone feature, so it won't work like the LD2450 can.

Hello, Very informative video. does it work with HLK-LD2410 sensor? thanks
@fixtse. Місяць тому
No, sorry, but the HLK-LD2410 it's officially supported by ESPHome esphome.io/components/sensor/ld2410.html so you should have no problem making it work.
@arslanpasha Місяць тому
Very nice video and presentation. I had my mmWave Sensor up and running in less than 20 minutes. Couple of questions. 1) HA plotly card: Is it supposed to show when a person is detected? (mine doesnt). 2) can you please do a tutorial to add a good Lux sensor and temp/humidity? I will have a perfect sensor to deploy all over my house :) Thanks in advance
@fixtse. Місяць тому
Hi, yes, check if they appear on the HLK app on your phone, if they do, something is wrong with the code you are using on the card. If not, try using the factory reset of the sensor (this will wipe any zone you configured, so copy the values first). Also, check my last video, I did just that.
@hakimril 10 днів тому
Hey, great video and amazing explanation. Does it work with ESP32 C6 Board. I want zigbee connectivity instead of WIFI. Also, ESP32 C6 board doesn't have RX2 and TX2 pins, so what are the alternatives? Thanks in advance and keep up the good work!
@fixtse. 9 днів тому
As far as I know, almost any pin on the ESP32 could be configured as RX-TX (unlike on the esp8266), so that shouldn't be a problem. For the zigbee connectivity part, that needs more work on the ESPHome side (currently the firmware doesn't support to create custom zigbee sensors), not sure if adding support for creating zigbee devices is on their roadmap (zigbee devices are supposed to need a certification from the zigbee aliance, still I just transformed an Aqara Temperature Sensor from Bluetooth to Zigbee with some special firmware, so I'm not really sure anymore)
@MarcosCardoso-fi7ez Місяць тому
Hi. Can you add a luminance sensor to the project? Thanks, Best regards.

Hi Fixt, everything installed fine, but, I don't get any info on Target 2 or 3, Target 1 has data, same on HLK app or in HA
@fixtse. 14 днів тому
mmmm try restore the sensor to factory using the HLK-app (it has happen to me before and that fixed it, it will erase all your zones, so copy the values before). If that doesn't work, it might be something with your sensor.
@krismccormic7106 25 днів тому
I've tried this project with two different D1 Mini ESP8266 NodeMCU ESP32 ESP-WROOM-32 I had here, but neither of them worked with the custom flashed firmware: all devices were "unknown". Is this for just the specific device you linked or will it work with any generic ESP32 device?
@fixtse. 24 дні тому
Hi, it should work with any ESP32 device, if for some weird reason ESPHome doesn't detect your specific board variant (some new esp32s variants need this) you need to add specify it on the yaml file.

@byurhanbeyzat Місяць тому
Hi, I have a quick question why there is 2.4GHz PCB antenna connected to the mmWave sensor? Does mmWave connects to the wifi or something?
@fixtse. Місяць тому
Hi, no, the PCB antenna is used to extend the bluetooth capabilities of the sensor (The bluetooth is only used to connect to the sensor using the HLK App). The wifi is managed using the ESP32 board alone.
@Fedeleallalinea56 29 днів тому
Which board are supported? Esp32c3 super mini? Esp32 mini wroom 32?
@fixtse. 26 днів тому
So far I tried it only on the ESP32 Wroom 30 pin board, but it is still ESPHome firmware, there is no reason for it to not work on thoose boards (the suppor for the minis is still experimental, but it mostly works).
@rgnyldz 11 днів тому
Is this built on esphome or is it a custom firmware? Because As I understand the base esphome does not support HLK2450 right now. The reason I ask is can we add additional sensors to this?
@fixtse. 9 днів тому
Yes, it's ESPHome, using a custom component to make the HLK2450 work. Yes I have a follow up for this video where I added a light sensor and a temperature/humidity/pressure sensor to the project

@luckymaisie124 Місяць тому
Is the sensor placement directional? as it looks to be mounted at the back of the unit ? Is there any logic around this ?
@fixtse. Місяць тому
Hi, yes, it's directional. Yes, that is actually the front (that's why I put the logo on it, I know that seems like a weird placement). There are three main reasons for this: - Since this is intended to be just a pressure-fit case, and PLA pieces tend to loosen over time, I prioritized having the base attached to the bigger part of the case to put less stress on the smaller parts. - I considered moving the ESP32 board inside the case to get around the first limitation, but it made the installation and handling of the sensors more complicated, so I scratched that idea. I also considered moving the base to the bottom of the case, but that messed up with the stability (I could rework the joint in the future to get around it) - One of the main limitations of mmWave sensors in general, is that they can't easily distinguish persons from pets, so a way to work around this is to mount the sensor at an elevated position, looking a little bit down. And in that case, the placement of the base attached "to the back" helps us to achieve that. I hope this provides more clarity regarding the thought process behind the design! 🤓

Can it also work with ESP32 S2 board?
@fixtse. 26 днів тому
The board has experimental support on ESPHome, so it could work (it won't break the board, you can safetly try), acording to the documentation (esphome.io/components/esp32.html#configuration-variables ), it might need an extra flag in the yaml file, to specify the exact variant, if for some reason ESPHome doesn't detect it automatically.
