It's good that you have it figured out. What is the Map setting for SM2235? I'll add this device to supported list.

Thanks. I'll just put here a screenshot from the shop offer so we know which device we're talking about: Added after 52 :Part Number ‎LTD-SM-G16.5-E12-4P Item model number ‎LYS-009 ASIN B0BS14VHH3 Wattage ‎5 watts Bulb Shape Size ‎G16 1/2 Bulb Base ‎E12

Strangely, one of the bulbs did not work with pins 7 and 9. I got it to work briefly using pins 8(clk) and 9(dat). But now it won't light up again.I will do some more tinkering to figure this one out. I don't want to take this one apart since I already busted apart the one spare bulb I had.

Do you have 2 MB dump? Latest flasher can extract Tuya config.

Wow! That worked! I pulled the dump from the bulb I disassembled, put it in the flasher and it gave me the config and now the bulb works!You are awesome, thank you so much for everything you are doing!

Pin 7: SM2235CLK
Pin 9: SM2235DAT

Thanks for all you do!

Hello!

I'm back with another generic bulb. Any help would be very much appreciated.

I feel silly that I can't figure this one out. It is SM2235, BK7321N, and CBLC9??? Board does not have marking on it, but it looks similar to the writeup on this forum.

The pinouts aren't making much sense and I've used multiple combinations of the PWM pins. Nothing works.

Topic summary

The discussion revolves around configuring the Generic (Lightinginside) E12 bulbs, specifically the SM2235 model. The original poster initially struggled with the pin configuration but later resolved the issue by using Pin 7 for SM2235CLK and Pin 9 for SM2235DAT. Additional insights included the mapping for SM2235 (Map 2 0 1 3 4) and troubleshooting steps involving a 2 MB dump extraction using the BK7231GUIFlashTool, which ultimately led to a successful configuration. Some users reported issues with certain bulbs not functioning correctly with the specified pins, indicating variability in performance.
