Protocol Lacrosse

LaCrosse LW30x

Setting up LaCrosse LW30x hardware by hand, in weewx.conf.

Generated by tools/build_protocols.py. What each protocol needs is written in that tool; what it is called and what goes into the console comes from the code. 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://1.2.3.4:8080/?token=abcdefg12345

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

LW301 and LW302 gateways, with the wind, rain, UV and T/H sensors

In protocols = auto	yes
Named by	its mac
Can be set up before it uploads	No, it is adopted

The smallest configuration that works

[Station]
    station_type = UltimatePush

[UltimatePush]
    driver = user.ultimatepush.driver
    port = 8000

    [[stations]]
        [[[garden]]]
            id = 001D0A712233

The identity is the hardware's own and cannot be chosen, so this line cannot be written until the station has uploaded once. The log prints it the first time, ready to copy, and until then the station shows in the web interface as one waiting to be let in.

What else it takes

A gateway cannot be told where to post, so box.weatherdirect.com has to resolve to 1.2.3.4 on your network. With dnsmasq:

address=/box.weatherdirect.com/1.2.3.4

It posts to port 80, so redirect that:

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8000

Once it is pointed here it no longer reaches its own servers.

Options of its own

None. Everything that applies to this protocol applies to all of them, and is in Configuration.

Worth knowing

The same as Acurite in every respect that matters: the gateway posts to its manufacturer's server, the name is in the firmware, and only a DNS entry on your own network can move it.

Once it is pointed here the manufacturer's app stops showing the station.

When nothing arrives

As for Acurite. The name to redirect is different and is below.

More than one station

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