    Yesssss: it was the wrong Battery Relay PIN!!
    :)))

    Yippee: works like a charm now.

    One very last question remains: Does the
    min_V:2200
    refer to the device's minimum voltage to be operated? And if so, wouldn't it be wise to set the battery driver to a value around or even to avoid "deep-sleep-wake-up"-issues?

    Quote:
    Device configuration, as extracted from Tuya:
    - Button (channel 0) on P20
    - Status LED on P26
    - PIR sensor on P16
    - Battery Relay on P17
    - Battery Max Voltage: 3000
    - Battery Min Voltage: 2200
    - Battery ADC on P23
    Device seems to use Battery Driver. See more details here: https://www.elektroda.com/rtvforum/topic3959103.html
    Device seems to be using CBU module, which is using BK7231N.
    And the Tuya section starts at UNCOMMON POSITION 0
