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!!
-
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.

You are always do very clear and easy to follow videos. Keep it up.
-
Love your videos, you make it all so easy. Many thanks.

Brilliant, looking in detail tomorrow. Subscribed

You deserve so much more subscribers & views!

Nice structured video
-
Really glad to be a part of this GREAT work!! 😁
-
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
-
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.
-
Thanks for an inspirational video! Do you know if it's possible to use the HLK-LD2410B instead?
-
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.
-
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?
-
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!!!!!!!
-
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

I can't seem to get past the "Preparing Installation" step. I've downloaded about every recommended firmware possible, tried every combination of boot and en button, and I cannot get it working. Edit: Disconnecting the sensor allowed me to install.

Grazie.

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!
