    I had the same issue, check your soldering of CB2S. Then it's back to normal Close-up of a circuit board with an attached relay and soldering on CB2S contacts.

    No, bad soldering after putting CB2S back after programming. Voltage, amp values were ValA, ValV. Fixed by resoldering.

    Is it so that the power monitoring chip BL0937 can not be assosiated with channels?

    If so, is there any other simlpe way to read values from this chip by PHP?

    cm?cmnd=status sounds a lot like it. How can I get power measurements only?

    Ahaa - seems to be status 8.
