    I have successfully flashed using tuya-cutter but when the controller boots it flashes the warm light until I press the button on the controller twice. After that it will allow me to control it from the webpage. Also the cool light does not work correctly. Am I missing something?

    I figured out the blinking. You need "tuyaMcu_defWiFiState 4" autoexec.bat. Tuya chip still thinks wifi needs to be configured on boot up.

    New autoexec.bat is as follows:

    Code: text Expand Select all Copy to clipboard
    
startDriver TuyaMCU
tuyaMcu_defWiFiState 4
tuyaMCU_setupLED 24 0

    Good job on resolving issue. I am seriously considering making tuyaMcu_defWiFiState 4 a default state because it seems..... it's always more required than I initially expected.

    You have all LED topics visible, maybe you need to do Home Assistant discovery again. Maybe you did it before configuring the LED.

    I have this working with version 1.17.262, but when I upgrade to 1.18.134, it no longer accepts commands from the webpage. The weird thing is that the button on the unit still works to turn the LEDs on, and the status on the webpage reflects the change. However, I am unable to control it from the built-in webpage. Anyone have any suggestions?

    That's a lot of versions in between, would you be able to narrow down which version first breaks?

    Then it's this PR from user...

    Probably g_tuyaMCU_allowAutomaticSending should be 1 to maintain backwards compatibiltiy..

    EDIT: The command is tuyaMcu_enableAutoSend, this is for autoexec.bat, the one with g_ is used in C code

    I tried OpenBK7231T_1.18.146 version with the following below and still does not respond to webpage. Back with OpenBK7231T_1.18.142 with tuyaMCU_allowAutomaticSending 1 or it also did not work with the line in autoexec.bat

    autoexec.bat
    startDriver TuyaMCU
    tuyaMCU_allowAutomaticSending 1

    Sorry, can you repeat? Does it work with tuyaMcu_enableAutoSend 1 in autoexec.bat or does it not?
    The command is tuyaMcu_enableAutoSend, the global variable in code is with g_ prefix, command is not.
    tuyaMcu_enableAutoSend is the only change made between releases breaking stuff for you...

    tuyaMcu_enableAutoSend is reverted to default state 1, but built came today, 1.18.148

    Thanks...That fixed the issues. tuyaMcu_enableAutoSend 1 in autoexec.bat does work.

Topic summary

The discussion centers on the FEIT Smart WiFi Light Strip (Model: FETAPE/RGBW/CNTRSC, FCC ID: SYW-TAPRGBWCNTRSC, chipset BK7231N) and its integration with OpenBK firmware and Home Assistant (HA). Key points include the necessity of using the native interface over the web app for proper RGBW (warm white) control, requiring flag 24 to correctly handle the RGBW channels as a single light rather than separate lights. Pin assignments for PWM channels and the smart button (pin 26) were identified, with PWM pins 6, 7, 8, and 9 mapped to PWM4 (warm white), PWM2 (green), PWM1 (blue), and PWM0 (red) respectively. Firmware updates fixed earlier issues with flag 24 and HA discovery.

The thread also covers challenges in flashing and debugging the BK7231N chip, including damaged diagnostic pads and the need for external probes. Users shared methods for flashing via Raspberry Pi UART and Cloudcutter, and discussed the use of TuyaMCU for devices with additional MCU chips, including capturing UART data to identify dpIDs for LED control. The TuyaMCU setup command and autoexec.bat configurations were shared to enable LED color control and button functionality.

Further discussion addressed Home Assistant integration, specifically the handling of color temperature ranges (Mired and Kelvin units), with the introduction of the CTRange command to set min/max Mired values for accurate adaptive lighting support. The web app's YAML generator was deprecated in favor of HA discovery, which now supports 4 PWM channels with the simulate white flag.

Issues with the physical smart button not updating HA state were resolved by adding firmware support for receiving dpID 20 toggle events, enabling state synchronization between the device and HA. Users also reported improved WiFi performance and local control responsiveness with OpenBK firmware compared to native Tuya firmware.

Additional troubleshooting involved devices with different hardware configurations, including those with extra chips requiring TuyaMCU communication, and the need for UART packet captures to map dpIDs. The community shared resources such as BK7231 datasheets, pinouts, and firmware repositories to assist in device configuration and flashing.

Overall, the discussion provides detailed technical guidance on flashing, configuring, and integrating the FEIT Smart WiFi Light Strip with OpenBK firmware and Home Assistant, addressing PWM pin mapping, flag settings, TuyaMCU integration, color temperature handling, and button state synchronization.
