I got the same results with the 60gjz fall detector. It picked up motion. Sports and presence but nothing else worked. What’s more odd is I was able to get 3 of the new 24ghz lite models and not a single one work. I’ve tried 9n 3 different Xiao’s, all ESP32-C3 with 3 different docks, the ones with the display and I get zero output from all 3. I’m wondering if something has changed as there is often updates to ESPHome and possibly to the Xiao also. It’s odd that that walk through “kind” of works with the 60hz fall detector but it’s way to sensitive for actual presence detection. Not sure what I could of done wrong. Downloaded the same . H file as referenced in the wiki. Have everything hooked up correctly from the UART port using a grove to femail adapter. TX is going to RX and vice versa. 5V and ground are hooked up correctly so I’m at a bit of a loss. It installs with zero issues. At first I thought I might of got a bad MmWave sensor but I highly doubt I got 3 and the Xiao’s all work when the 60ghz fall detector is hooked up.
I also tried hooking them to the pin holes with a male to female Dupont cables and the same results. Has anyone got that working with the new lite models? Just want to know if I’m doing something incorrectly or if something has changed. Especially since the 60gjz one works, at least partially but nothing works on any of the newer model ones that the wiki uses. Everything installs in ESPHome with zero issues. Just no output from any of the new 7 dollar 24ghz models. If anyone has this working let me know and I will look find the issue but I e given up for the moment.
I did have some temperature and other sensors hooked up before I moved to just the MmWave presence detector but I cleaned all the build files and actually deleted everything and started from scratch but have the same results. All my other grove modules work with zero issues so I’m wondering if something else changed, possibly in ESPhome or the R24****.h file that you have to download. Any input would be appreciated. Thanks in advance. It wouldn’t be the first time an ESPHome update has broke something that was working previously which is about the only issue with monthly releases for Home Assistant. To many breaking changes.
