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 previous 3 years I was using the Python script weewx-interceptor modified to send the received sensor values into openHAB via @Piotr_Bojko’s Webhook binding. However, weewx-interceptor would only work with Python 2 and after upgrading my openHAB server, Python 2 was no longer available.
Using GitHub Copilot, I was able to quickly translate the Python code from weewx-interceptor that handled low-level communication with the La Crosse GW1000U ERF gateway into Java and thus allow openHAB to natively support these devices.
This binding fully emulates registering the gateway and the TX60 sensors for new or recycled devices. Registering a weather station that was previously registered with the La Crosse server should work but has not been tested. The best chance for success when using this binding is to use it with a weather station or sensors that were setup on and communicating with the lacrossealertsmobile.com server.
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. It is not recommended to purchase these devices now unless the price is very low. It is no longer possible to register/re-register a gateway with the La Crosse server. If still using the La Crosse server, do not factory reset any of the devices that are currently registered as it might not be possible to re-register with them.
La Crosse Wireless Weather Station: Wind Rain Temp Model #C84612
La Crosse 926-25101-GP (TX60-U sensor and GW1000U gateway)
Use the following instructions to configure the devices to work with openHAB:
-
Create the appropriate Thing and enter the hex serial number for the gateway and for the TX-60 sensors all of the serial numbers found on the stickers on the back. If the sensors are already registered with the gateway, they must be entered in the same order as recognized by the gateway. Enter the serial number for the weather station if available.
-
As outlined in post #2, use the gateway configuration tool to change the gateway’s Proxyserver IP to your openHAB server’s IP address and port 8080 and save the configuration. Then remove and re-apply power to the gateway. The gateway LED should blink and if previously registered will eventually become solid red. Check
http://$OPENHAB_IP:8080/request.breqto verify that the gateway is listed and shows as online. If the gateway is not registered, the LED will blink in groups of 4 blinks. In this case, press the gateway button briefly to initiate registration. The LED will turn solid red or blink and then turn to solid red. Upon rebooting the gateway, the LED should blink and then eventually turn solid red. -
If the sensors or weather station are already registered to the gateway, the data they periodically transmit should now flow into the binding. At this point configuration is complete.
-
If the weather station is not currently registered to the gateway, follow its instructions to register it. If the TX-60 sensors are not registered to the gateway and the sensor is not displaying a temperature, they must now be registered in the order that the serial numbers are entered in the Thing. To register with the sensor near the gateway, press the button on the sensor and hold for one second and then immediately press and release the button on the gateway. The LEDs on the gateway will blink and then the sensor will reboot and start displaying the temperature if registration was successful. If the sensor is not registered but still displays a temperature it must be reset by holding the button until all segments on the display illuminate. After this remove and replace the batteries and then attempt registration again.
-
If it is necessary to factory reset the gateway, first remove power to it. Then hold the button and re-apply the power. While continuing to hold the button wait until the red LED comes on, then goes off and then comes on again. Then release the button and the gateway should reboot to factory settings. Now repeat steps 2 thru 4 to re-register the gateway and weather station or sensors.
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).
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 hex serial number that is needed for the Thing configuration. The hex serial number value can also be found on the gateway’s web page.
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.
If the weather station was previously registered with the La Crosse Alerts, and is still registered with the gateway then entering the station serial number is optional. The default value of 0000000000000000 should work.
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
