I have been trying to find this device for awhile. I’ve used my energy meter on devices which I think may be it but to no success. There doesn’t seem to be a pattern of when this turns on and off. I have exported the data to a spreadsheet for this device but I’m not sure if that would help someone assist me in tracking down this device.
Sense says the device is 93% chance a pump so it seems quite sure that it is. Here is a link to the exported data.
Any help would be appreciated!
