Well. Bought the stuff in your links. Put together. Works with the apps from the write up. Home assistant see's and adds the sensors. Home Assistant doesn't see anything but the app sure does. Granted the esp32's linked in the amazon link are not the same as on the write up. Didn't notice until already ordered and putting together. Where the rx2 and tx2 is suppose to be are D16 & D17. Going to bet thats my issue....

Your videos are so great. You do a great job explaining everything and your site is so awesome to have as a reference. Keep up the great work!!
-
Brilliant, looking in detail tomorrow. Subscribed
-
Love your videos, you make it all so easy. Many thanks.
-
You are always do very clear and easy to follow videos. Keep it up.
-
Excellent, succinctly explained. Great tutorial.
-
Thank you Very Much. It works great!
-
really great - keep doing what you are doing. Some people are upset about "paywall" but that is not right. They can still use the precompiled images
-
Nice structured video
-
You deserve so much more subscribers & views!

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.

Really glad to be a part of this GREAT work!! π
-
Thanks for an inspirational video! Do you know if it's possible to use the HLK-LD2410B instead?
-
Hi grate video my device is up and running. I was trying to use the blueprint that you supplied but i cant get it to work with the zones so its all or nothing. is there a way to use it with the 3 zones set up?
-
Great video, everything is clear and easy to understand - great work. I ordered the case from PCBWay made from resin and unfortunately some of the pieces do not fit properly, i.e. the ESP32 board is loose inside the case.
-
Hiya Fixt - just a quikc question - how impt is having a case for this setup ? I mean as long as i have the antennas facing the right way it shou ld be fine? Thanks for your kind advice.
-
Hey thank you for all your videos, your projects are really awesome. For the firmware do you plan to release yaml? I want to use my other esp32 boards, the esp32 c3 super mini.
-
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!
-
Are you able to add additional sensor like temp, humidity, lux and so forth to the same board and update the files right read all?
-
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
