FineOffsetUSB

Running the FineOffsetUSB driver under this one, configured by hand.

Generated by tools/build_drivers.py from the driver as installed on the machine that ran it. Do not edit by hand.

There is a web interface for all of this. It is on by default, and the driver prints its address when WeeWX starts:

INFO user.ultimatepush.driver: The web interface is at
http://192.168.1.50:8080/?token=kJ7mQx2vRt9w

Everything on this page can be done there instead, and one thing is much easier: deciding which reading goes into which database column. See Web interface.

What it is

Classes and functions for interfacing with FineOffset weather stations. FineOffset stations are branded by many vendors, including

The smallest configuration that works

[Station]
    station_type = UltimatePush

[UltimatePush]
    driver = user.ultimatepush.driver

    [[hardware]]
        station_types = FineOffsetUSB

        [[[FineOffsetUSB]]]
            role = main

[FineOffsetUSB]
    driver = weewx.drivers.fousb

The [FineOffsetUSB] section belongs to that driver and is read by it, exactly as it would be if it were the only driver WeeWX ran, so weectl device keeps working on it. What goes under [[hardware]] belongs to this one: see [Hosted hardware](Hosted- hardware.md).

Finding it

There is nothing to look up. The driver searches the USB bus for the device itself.

If it does not find it, the usual cause is permissions: WeeWX runs as the weewx user, and a raw USB device belongs to root until a udev rule says otherwise. WeeWX installs those rules for the hardware it supports. Check with:

lsusb

and look for the console in the list. If it is there and the driver still cannot open it, the log says so with the vendor and product number, which is what a udev rule needs.

Every option

Straight out of weewx.drivers.fousb, with what its author wrote above each one.

model

The station model, e.g., WH1080, WS1090, WS2080, WH3081

Default is WS2080.

polling_interval

How often to poll the station for data, in seconds

Default is 60.

driver

The driver to use:

Default is weewx.drivers.fousb.

More than one station

This driver is one station among however many others. Which of them fills outTemp, and where the rest of their readings go, is in Several stations.
