Got some mini switches to check for 2026.
This one is rather unusual, it has BL0937 metering chip, which I have not seen in mini switches yet. CB2S module is mislabeled on this switch. Has usual standard BP2525 and AMS1117 3.3V regulator chips. There is space to upgrade capacitors.
Config should be like this (not tested)
