Hey. I watched theme from ecigtalk.ru and found another custom firmware for these devices.
You could visid original theme Кастомная прошивка, ремонт, технические вопросы по Sigelei 213, Fuchai 213, Fuchai Plus
http://xvtx.ru/ecig/files/Manual_eng.pdf
Site is http://xvtx.ru/ecig (english too)
I do not want to write more now, coz I don't know who needs, I do not have these devices, but it can be useful.
Main abilities
Support USB for connecting to a PC with the ability to obtain telemetry and firmware updates;
Expanding the capabilities of the firmware (Eight mode profiles, battery profile, puff count, selection of more than 20 parameters for display on screen, protection in watts and percentages, additional varivolt mode, downloadable logo);
More complete support for iron capabilities (display brightness control, inversion, screen and button flip, stealth mode, sleep mode, ADC hardware interrogation, DMA-ADC, DMA-OLED, internal CPU temperature sensor, special modes of hardware charger, balancer etc.)
