Works exactly the same as the other LD2410 variants, basically a different form factor (IMO a better one). Used the same code for both sensors, but have not tested side by side, since I ran out of ESP dev boards 
Dont know if it supports BT, as I can’t install the app on my phone.
Yup! Got mine too
Each get command “reads” that specific part of the config.
[edit] I think there may have been some confusion here between read literal and read the verb/action/intention.
You can, “read the config” using the provided get commands.
You cannot readConfig as that is not the literal command to type in order to do so.
I recently got a DFRobot mmWave and noticed it’s detecting me on the back of the sensor too (at a shorter distance) but this doesn’t seem to happen with my mmWave sensors from LeapmmWave (the original manufacturer)… do you guys have same experience or is my sensor defective?
hello! i have very specific question to ask , i was watching everything smart home (this video Building My Perfect Smart Home Presence Detection Sensor! - YouTube) and he used this code and stuff to get his mmwave sensor working and im trying to do the same but im confused, the pin-out of the board and the way he soldered it out shouldn’t work but his does, he put the sensor in i022, i021, i017, i016, and of course GND and VCC (5v) but on the df robot page it says you need the rx and tx to be plugged in, im wondering how i can do the same as him and get my sensor working, i hope someone can help because im at a loss, i wish he could have shown the install of the code 
The ESP32 can do serial RX/TX on other pins as well. In fact the pins RX/TX are normally connected to the USB to serial chip and used to flash the ESP32 via USB
So how would I put it in the code? Would I put it as i022 and i021?
Yes just put the PIN number, if it doesn’t work switch them
yeah i posted about it on a different thread and got some help but i get this after the install and i get no detection data
nvm i fixed it had to change the gpio pin to 17 and that did the trick
looks like a perfect case. What are the dimensions inside? would a esp32 d1 mini fit inside? also is the base hollow? it its hollow I´m thinking I could add a temp sensor there, perfect spot, below the esp32 so the heat from the board would not affect it.
Hi, I have a little problem with the esp8266 mini d1 and the SEN0395. it works fine, but after few updates, the blue light on the d1 turn on and will not boot, its like is stuck in boot-loader. If I re-flash it ad remove the code from number then works fine, but I cant configure it. If I flash the code to a new esp8266 then it works fine, but again, because I’m trying different sensors and configurations, after few flashes, again. I also included a bme680 and bh1750.
My code is bellow. any help how I can get around this problem, I have 2 boards that I can only use if I remove the code from number to bme680_bsec.

Standard troubleshooting procedures apply; use a systematic approach.
I would personally remove everything, add one thing at a time and run for a week to prove that in isolation, all things before it work.
The 8266 is pretty underpowered compared to a 32 and the webserver & debug can add quite a bit of load/memory_consumption based on my experience. Don’t add what isn’t 100% necessary.
I tried, even if I remove everything but the mmwave still the same unless I delete the latency, sensibility and distance.
Have you tested restore_value: false ?
I tried with optimistic: true, optimistic: false, restore_value: true, restore_value: false also removing the 2 values
Have you tested with nothing but a ‘dummy’ number: configuration?
Eg.
number:
- platform: template
name: does_nothing_number
id: does_nothing_number
min_value: 0
max_value: 800
initial_value: 315
optimistic: true
step: 15
restore_value: true
unit_of_measurement: cm
mode: box
with one dummy number works, thank you for the idea. I then created 4 dummy numbers, works fine, I then remove all and added only one, tried the 3 numbers mmwave_latency, mmwave_sensitivity and then the mmWave Distance, with any of the 3 fails. if I remove the code then doesn’t get stuck
