I have a number of zigbee-manageable Schneider Wiser 230V outlets that report Power Usage (InstantanousDemand, watts) that seem to be about 1000 times higher than normal (Ie, for a 900W load it reports 900000W :-). All other measurement values are reported correctly (Voltage, Current, Energy used (SummationDelivered

They are all running firmware version 002.006.018R. Anyone else have them and also seeing this? ).

Does there exist a newer firmware for these units that fix this problem? (I'm using them via Home Assistant and a third-party zigbee gateway so they aren't receiving any firmware updates - if any exist that is...)

Other than this small issue they are working fine. (I have a working workaround using a HA/ZHA "quirk" patch that corrects this, but if there is fixed firmware out there then that fix would need to be removed/or adjusted to detect the firmware version and selectively enable that adjustement.
