Which hardware is the custom firmware being developed for?

Good day, I saw in one of the issue threads that the LD-6004 will be supported by the custom firmware which you are developing. I was wanting to ask what other hardware are you building for? What would be the preferred unit and if you are able / willing to share a rough eta?

As it stands right now I have M100's in every room which are working fine for presence but they required disabling some features to prevent the units from spamming and crashing our Zigbee network.

Thank you for your time, I've been following the project for some time now and am excited to implement it.

Hi! Thank you so much for following the project and for your interest in the custom hardware!

The custom hardware units I am building are strictly Wi-Fi based, utilizing high-speed MQTT and direct WebSocket tunnels. Currently, the firmware natively supports the HiLink LD series, specifically the LD2450, LD2452, LD2460, and LD6002B. As for the LD6004, I am currently deep in the debugging and integration phase for it. It is not yet available in the store.

Zigbee is a brilliant protocol for low-power, low-bandwidth devices (like door sensors or light switches). However, it is physically not designed to handle high-frequency continuous data streams.
Tracking radars output X/Y/Z coordinates (and sometimes point-cloud data) at 5Hz to 10Hz. Forcing this massive amount of data through a Zigbee mesh will instantly choke the coordinator, causing network-wide delays and crashes (the "spamming" issue you experienced).

That's why my architecture exclusively uses Wi-Fi. By streaming the high-frequency radar data directly to the RMM frontend memory via WebSockets, we completely bypass the Home Assistant state machine and database.

I have to give this a try! I have a LD2450 here, But I came here looking for a tool for the LD2420 that I am currently using, I chose this one because it had better distance/range, but I struggle with adjusting the zones sensitivity when I can't see feedback on individual zones. Have you tried it with your tool?
