+1 to vince's comments. USB should be ok if your power supply is adequate. > I'd like to "split" my USB data from a Vantage Vue console between my > production weewx Pi 4 and a development Pi 4. weewx is working well using > the Simulator on my development Pi, but I want to feed it actual data and > use the Vantage driver.

USB is a two-way bus, with one originator (a computer) and some number of devices (serial ports, disks). The hub is plugged into the computer, making it act like it has more ports. You can't use a hub to put one serial adaptor on two computers. The two-way part means that the computer sends bytes to the console (really to the 6150USB data logger) and the console replies. So yes, you could fake up something where the bytes are proxied across and the other computer's commands go nowhere. But as people said, mqtt transmit is the way to go. Or, you can just move it to the development box for an hour, and then back. If the developemnt box doesn't clear the logger, the production one will fetch the old records and all will be ok. > Both systems are using weewx 4.1.2. That's old, but that's not relevant to this discussion. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
