For people in need of switching USB power to Fine Offset should it be 
needed, I have a news I did not find is published.

There is another switchable USB hub that is currently available. Plus, it 
is one of the quite rare hubs not backfeeding power to the RPi (or any 
other device) controling it!

Transcend USB 3.0 Hub 4 Port Powered Hub3 

Take care: there is almost identical HUB2 which does not have external 
Power Supply. I am talking about the HUB3. Back is labeled: TS-HUB3K. Power 
supply is declared at 18W.

mine are identified as:
ID 8564:4000 Transcend Information, Inc. RDF8

All 4 ports respond to power commands, but only port 1 actually kills the 
power. This is the single port on the side - FO should go there.

Power stability is not excellent, we may call it very good:
4,85v @ 0,94A
4.75v @ 1,62A 
4.74v @ 1,86A

For RPi running WeeWx and a Fine Offset, I would not expect problems with 
both RPi and FO powered from it. WeeWx should have no problem controling 
power to the FO using this hub (I did not verify WeeWX control of the hub!).

Hopefully, they did not "improve" it with new revisions cheaper to produce. 
Mine were made in 2016.
