[w800] XM-HE201 24G Sensor flashed to OpenBeken, sensors partially working

Question 1

Hold the boot pin to ground during power‑up. The UART will stream “C” when the bootloader awaits firmware. Use TX0/RX0 for flashing with wm_tool.exe. TX1/RX1 are reserved for the LD2410B mmWave module. This sequence reliably enters flashing and avoids interfering with the sensor UART. [Elektroda, juanwick, post #21796926]

Question 2

Map Pin 21 to the PIR input and Pin 24 to the LD2410B’s GPIO. Set them to DoorSnsrWSleep for battery‑type behavior or switch to dInput if the device is mains‑powered. This exposes motion states without a custom UART driver. [Elektroda, insmod, post #21799291]

Question 3

Not yet. The LD2410B uses UART on TX1/RX1, and a driver is needed to parse its frames. An OpenBeken developer noted uncertainty about a generic UART driver on W800 and requested captured packets to proceed. “UART protocol ... looks more advanced.” [Elektroda, p.kaczmarek2, post #21799119]

Question 4

That light device is on I2C, not analog. Setting the pad to ADC will return meaningless, flat values. Reconfigure the pin as I2C (SCL/SDA) and query via the light driver once identified. The user’s constant 10k–12k readings came from treating an I2C sensor as analog. [Elektroda, juanwick, post #21799142]

Question 5

It visually matches Lite‑On’s LTR‑303ALS family. Logs show I2C PART_ID 0xA0 and MANUFAC_ID 0x05, which supports an LTR‑series ID pattern. Use these IDs when binding an ALS driver in OpenBeken. [Elektroda, juanwick, post #21798545]

Question 6

Capture raw UART frames from TX1/RX1 while the sensor operates. Share logs with timestamps and baud. The maintainer asked for packet captures to implement parsing on W800. Use a USB‑TTL adapter in parallel with the module for clean traces. [Elektroda, p.kaczmarek2, post #21799119]

Question 7

Use the BK7231 Easy Flasher before writing OpenW800/OpenBeken. It can dump the W800 image, which helps recovery and Tuya config analysis later. This avoids losing Wi‑Fi credentials and GPIO maps if extraction works. [Elektroda, divadiow, post #21797071]

Question 8

Backups can be valid yet lack a readable JSON header for Tuya config. Logs show “Failed to extract Tuya keys – no json start found,” even when SSID/password are present. This is a known edge case for some W800 images. [Elektroda, juanwick, post #21797096]

Question 9

No. The board uses USB‑C power and includes two USB‑C ports to simplify mounting. For mains power, assign digital inputs as dInput rather than DoorSnsrWSleep to avoid sleep semantics. [Elektroda, p.kaczmarek2, post #21799297]

Question 10

A shared log shows TY IOT SDK 2.3.0, firmware V1.1.3 (Jun 16, 2023), and free_mem_size 77,824 bytes. It also records repeated I2C PART_ID reads and a “Start Timer Fail ... -2,” indicating a timing issue during init. These stats help compare runtime behavior. [Elektroda, divadiow, post #21798204]

Question 11

Answer

Ground the boot pin and power the board; wait for continuous “C” on UART.
Connect TX0/RX0 to your USB‑UART; run wm_tool.exe and flash OpenBeken.
Reboot, then configure Pin 21 (PIR) and Pin 24 (LD2410B GPIO). [Elektroda, juanwick, post #21796926]

Question 12

OpenBeken is community firmware that replaces Tuya builds on W800 hardware, enabling custom pin roles and drivers. Users have flashed XM‑HE201 successfully and begun mapping PIR, mmWave GPIO, and I2C light functions under OpenBeken. [Elektroda, juanwick, post #21796926]

Question 13

Yes. A contributor posted screenshots of the OEM Tuya UI with motion and light elements. Reviewing them helps you map expected datapoints when recreating behavior on OpenBeken. Use these as a baseline for MQTT/topics later. [Elektroda, divadiow, post #21798204]

Question 14

One unit arrived labeled S1KM0000 and was notably small. Minor revisions can alter pin routing or sensor markings, so verify pads and IDs before assuming the same map. Photograph your PCB for future reference. [Elektroda, divadiow, post #21806677]

Question 15

wm_tool.exe flashes firmware over UART; Easy Flasher backs up W800 images; LD2410 tool.exe talks to the mmWave module over TX1/RX1. These tools cover flashing, recovery, and sensor diagnostics. [Elektroda, juanwick, post #21797096]
