Hi @felmue,
Unfortunately on my M5StickPlus axp.setLcdBrightness(50) gives an error.

Maybe it has different MicroPython hardware APIs than your device?

Hi,
Which MicroPython APIs can help reduce power drain on M5StickCPlus?

I was unable to get basics to work:

• lcd.setBrightness(0-100) # didn't change LCD backlight brightnes
• power.getBatteryLevel() # didn't seam to work
• No API to turn off wifi mentioned at: https://github.com/m5stack/UIFlow-Code/wiki/Advanced - does this work: wifiCfg.wlan_sta.active(False)

Are there other APIs to turn on/off parts of device , or to reduce power drain?

Thanks
