I made this binding to connect my La Crosse TX60-U sensors to openHAB. It also works with the La Crosse C84612 Weather stations (not yet tested). For the past 3 years I have been using the Python script weewx-interceptor modified to send the received sensor values into opehHAB via @Piotr_Bojko’s Webhook binding. However weewx-interceptor would only work with Python 2 and after upgrading my openHAB server recently, Python 2 was no longer available.
Using GitHub Copilot, I was able to quickly translate the Python code from weewx that handled low-level communication with the La Crosse GW1000U ERF gateway into Java and thus allow openHAB to natively support these devices.
Note that both the C84612 weather station and the TX60-U sensors are discontinued but can still be found on eBay in limited quantities. The TX60-U sensor can be found in a kit containing the GW1000U gateway under part number 926-25101-GP. Individual sensors seem to be very hard to find.
La Crosse Wireless Weather Station: Wind Rain Temp Model #C84612
La Crosse 926-25101-GP (TX60-U sensor and GW1000U gateway)
And now the standard README…
La Crosse Binding
This binding receives data from La Crosse C84612 weather stations or TX60-U temperature sensors via the hardwired Ethernet GW1000U ERF gateway.
Please note that this binding has not yet been tested with the La Crosse C84612 weather station.
The GW1000U must be configured to use the IP address and web server port of the openHAB server as its Proxyserver in order to use this binding.
The Gateway Advanced Setup (GAS) utility from La Crosse is used to change the gateway’s settings.
After this setting is changed in the gateway all data transmitted will be re-directed to openHAB.
Note that this also prevents any of these devices used with openHAB from using La Crosse’s online services (lacrossealertsmobile.com).
If you have any intention of using La Crosse’s alerts service, you should register your weather station with La Crosse before using this binding.
The routines used to allow communication with the gateway were adapted from weewx-interceptor and translated into Java using GitHub Copilot.
Most of the knowledge on how the GW1000U communicates was originally discussed here: https://www.wxforum.net/index.php?topic=14299.0
Discovery
Discovery is not supported. All things must be added manually.
The LacrosseInterceptorServlet can be accessed at http://$OPENHAB_IP:8080/request.breq to verify that it is active.
Any gateways that are configured to connect to openHAB will be displayed here along with the serial number that is needed for the Thing configuration.
The easiest way to obtain the serial number for the C84612 weather station is to register it with La Crosse Alerts and then view the serial number on their Device Settings page.
The serial number for a TX60-U sensor can be found on the sticker on the back of the sensor.
Once the things are configured properly, they will change to ONLINE status upon receipt of data from the gateway. Note however the status will never change to OFFLINE.
Supported Things
C84612 Weather Station
Thing type ID: weatherstation
Receives all measurements from the weather station and its outdoor sensors (Wind, Rain and Temp).
The weather station cannot be used along with TX60-U sensors on a single GW1000U gateway.
Using the weather station and TX60-U sensors requires at least 2 gateways.

TX60-U Sensor
Thing type ID: sensor
Supports up to 5 TX60-U sensors per gateway, each as a channel group.
The sensors display the temperature reading in °F only.
If the sensors were previously connected to the gateway, the sensor serial number of each sensor must be entered into the same number configuration parameter as currently registered in the gateway.
Thing Configuration
| Parameter | Type | Required | Description |
|---|---|---|---|
| gatewaySn | text | yes | The serial number (8 chars) of the GW1000U gateway hosting the sensors |
| sensor1sn | text | yes | Serial number (16 chars) of the first TX60-U sensor |
| sensor2sn | text | no | Serial number (16 chars) of the second TX60-U sensor (optional) |
| sensor3sn | text | no | Serial number (16 chars) of the third TX60-U sensor (optional) |
| sensor4sn | text | no | Serial number (16 chars) of the fourth TX60-U sensor (optional) |
| sensor5sn | text | no | Serial number (16 chars) of the fifth TX60-U sensor (optional) |
Channel Groups
Each sensor (1-5) provides the following channels (All channels are read-only):
| Channel ID | Label | Item Type | Description |
|---|---|---|---|
| temperature | Temperature | Number:Temperature | Temperature measured at the sensor (°F) |
| temperatureProbe | External Temperature | Number:Temperature | Temperature measured by the external probe (°F) |
