7 months ago This might really be a ZHA issue. If the measurement type is kWh (0), we do not use the summation_formatting attribute for some reason. We only use the multiplier and divider attributes in that case: zha/sensor.py#L522-L531
@Adminiuga If you're around, do you have any idea why you added that check in the original PR? I'm guessing that it's unexpected the formatter is still needed for kWh? Or did some devices perhaps provide something wrong?
This can be worked around with a quirk. I'm not sure if that's a good idea though, as the plug seems to provide summation_formatting correctly: 00101010 => 2 digits to right of decimal point, 5 digits to left of decimal point.
Changing the ZHA code could break some other devices though. Especially the ones we have quirks for which set the multiplier / dividers right now.
.. but apparently we already use quirks for other Innr plugs though: https://github.com/zigpy/zha-device-handlers/blob/dev/zhaquirks/innr/innr_sp120_plug.py I guess I'll get one ready for this plug too for now.

Bug description
Upon inclusion of the INNR SP 240 in ZHA, among others a "Summation delivered" sensor gets created. The value returned for this sensor is however 100x larger than expected: I ran a filament dryer for 5 hours of the SP 240 and the device measured 17kWh instead of the expected 0,17 kWh as measured using a Fibaro wall plug V2.
When I requested help from INNR support they responded that ZHA probably has incorrectly interpreted the configuration their device returned. My translation of their response: "An attribute "SummationFormatting" on the Metering cluster has the value 0x2A, which designates: 2 digits to the right of the decimal point, 5 digits to the left of the decimal point, don't suppress leading zeroes". Looks like his system (red: my ZHA integration in HA)) doesn't interpret or incorrectly interprets the value of the "SummationFormatting" attribute."
The full mail text I got from INNR support (in Dutch, sorry):
@TheJulianJES requested me to tag him in here.
Steps to reproduce
Include the INNR SP 240 into the network using ZHA, plug in a filament dryer of 145W, Run the dryer for 5 hours, Watt history graph shows a peak at the beginning, then dropping to roughly 30 Watt. Multiply the measured Watt value with the number of hours: 5 * roughly 30 Watt = roughly 170 Wh, or 0,17 kWh. See how the actual sensor in ZHA however shows 17kWh.
Expected behavior
The summation delivered sensor should have shown a usage of 0,170 kWh
