LZW31-SN not reporting power after updating to v1.57 firmware

Hi,

I have a couple of LZW31-SN switches that I just updated to v1.57 firmware. Although the update process took a long time (over an hour per switch), it was ultimately successful.

However, I no longer received Power monitoring. Whether my light is on or off, I see 0W instantaneous consumption.

I have rebooted the device using the airgap switch, but it has made no difference.

Is this a problem with v1.57 or do I need to do something alternate to enable it? I have not tried to factory reset yet as I do not want to have to update all my configurations after it is re-included with a new node number.

Thanks,

Eric
