I want to try this too but before I start I just wanted to ask what USB breakout boards people are using?
It sounds like a stupid question but the reason I’m asking is because the follow up is, has anyone also designed an enclosure? If yes and they don’t mind sharing, why re-invent the wheel? If not then I’ll do one once I’ve got my parts up and running.
I’m having the same issue, with a twist. One LD2410C is working fine in HA but the HiLink App on my phone doesn’t see it. A second LD2410C is visible on the App but HA doesn’t see it. I’d like to be able to list all BLE devices connected to HA but I don’t know how to do this. Any ideas?
I thought about the same thing, and powered up another LD2410C and avoided connecting to it via the phone app. A bluetooth proxy is sitting right next to it, but still no trace of the device in the logs.
Mine has an unusable range for BT. Other devices work just fine even with multiple walls between them and proxy. With this sensor, I need a direct view of the BT proxy, otherwise it won’t work… Do you guys have the same problem?
I have been doing some more testing with this device (B and C versions and original with no Bluetooth) I have managed to get B&C to connect to HA over ble but connection is unstable. Initially, connection drops then reconnects every few seconds until connection becomes permanently unavailable. After this the only way I have managed to reconnect is after a reboot of the HA host device (Synology NAS)
However, connecting via ESPHome seems really stable and works well. Not quite so neat as you need the esp device connected but it works! I have only managed to do this with single wire I/o connection. Next step is to see if I can hook up UART to give better control. I have found this GitHub - rain931215/ESPHome-LD2410: ESPHome LD2410 mmWave Radar Sensor Custom Component but it appears only to connect tx and rx with no sensor connection?
Anybody else tried this esphome code?
Overall, when it works, the LD2410 looks like a really good presence detector with quick response.
I tried this before I realized that there where versions with BLE,
I used the Rx and Tx connector on the 2410 and Esp
It gives me some sensors like shown below
But the “Occupancy” sensor doesn’t really work i made a automation using the detected distance and triggered my lights on if it was above 30cm or so
I’ve switched my 2 x LD2410C to ESPHome for now. This seems to be stable. It only exposes 1 entity for occupancy ( or presence if you prefer) but it is still possible to configure the sensitivity etc. on an Android phone through the HiLink App. Interesting what you say @tom_hampton re the latest update. I have a couple more LD2410c on order from AliExpress so it’ll be interesting to see if I get the same results using ble with these.
I only get about 30cm bluetooth range from my LD2410B which is pretty poor. I can leave it next to the bluetooth stick but it just loses connection anymore than that. Bit disappointing but nothing a d1 mini won’t solve.
Edit: Seems to be similar to what others here mention and the app finds it across the room, just not the HA bluetooth integration (unless it’s next to it) so maybe there is hope in a firmware update…
