How-To Guide: Quick Start with L13 Sensors
Background
In the recent past, HLK has upgraded the LD2412 with a hardware model number LD2412S, which is claimed to have better antenna performance and better static detection capability.
We synchronized the latest LD2412S hardware and tried to incorporate the BH1750 light sensor (also used on the 2A), we call this upgraded L12 L13, and we will stop making the old L12.
The L13 has the same clean form factor as the L12, with easy access to HA capability.
In our testing, the distances are still not reliable, they show distances that are off.
It's easy to overlook that in addition to the 13 gates, 9m detection distance, and claimed better static capability, the HLK techs claim that the really powerful part of the LD2412S is the automatic interference detection capability. That is, the Auto button on the APP interface, or bottom noise detection. This feature clicks on Auto Detect when interference occurs, and will have the opportunity to use an algorithm to automatically eliminate the source of the interference.
I think this is something worth exploring.

Based on user morris1529 's suggestion, we have officially launched the recovery tool for L13. Like the other sensor's, based on ESP Web Tool, you just need to connect the sensor with a USB cable, open the web page, choose to connect, and then you can recover the firmware, configure WIFI, and check the running log. Very convenient!
