the question is frome Christopher Brower@FB.
Here are some of our thoughts:
1. I think most people just use it for human presence, as an alternative to pir. These zone functions and such would be helpful for filtering out some specific interference while working against a specific range when appropriate, or they could be used for a flexible arrangement, but only sensing the desired range.
In this general application, it's like ld2410 + a bit of range.
2. Or, it's kind of fun to imagine the kind of table light that comes on when you're walking near the table, and not when you're outside.By using the code from ha forumathua, we have created a handy online tool to create a dynamic ha card: https://docs.screek.io/2a/add-a-map-card. It will be interesting to see from this visualization.
3. The LD2450 is a very landmark 24G radar, enabling the display of human coordinates at a low cost, considering it came out almost at the same time as the fp2, which was much more expensive. And the fp2 didn't have the means to completely tame ghosting. But through the power of DIY, the LD2450 uses completely localized communications, and the openness of the entire source code lets us know it's hard to do evil. In a sense, it made our HA a lot more fun, and for me, especially when we put the room's target map card in the HA's card, I thought, this is tech! Belongs to this AI era. While it's still not perfect, on balance it represents the dawn of an era of low-cost multiplayer tracking radar.
