A complete La Crosse Technology manual, should contain several basic components. However, the remaining part should provide us with information that is important from the point of view of the user. If a user had a similar problem with La Crosse Technology TX7U it is likely that he will want to share the way to solve it. But it turned into a Photon project when I realized I didn't want to go through the learning curve of configuring WiFi connectivity with an Arduino. Furthermore the Photon has more processing power so that meant I didn't have to be as concerned about code optimizations. The additional power came in very handy when I started using making extensive use of Serial.print statements. The Arduino was not able to keep up with that level of serial output where the Photon handled it well. Below is the end result of what gets posted. For Weather Underground only one sensor is posted but for Thing Speak I'm posting the data for three different sensors that are located in different areas of my home. Weather Underground provides much more than what I'm showing in this screen print and has a huge ecosystem for setting up your own personal weather station.This app has ended up being my primary way to view the data as it's so convenient. I've owned a Lacross WS8610 weather station for years.
It can work with up to three different remote units ( TX7NU ). I also bought a WS8610 for my parents and set them up with two remote units. My goal was to find a way to read the 433Mhz temp and humidity broadcasts from multiple remote sensors and post them to various data collection websites and then geek out with the weather data. Capturing and analyzing 433mhz transmissions The first step was to start making sense of the transmissions from the 433 mhz weather sensors. This involved using a USB to 3.5 mm audio adapter as a means to send the signal being picked up by the 433mhz receiver to the PC microphone input. That signal could then be viewed using Audacity which functioned as a very crude oscilloscope. This gave an initial view of when the transmissions were occurring for each of the three TX7U sensors. Each one would send a broadcast about every 57 seconds.There are additional links in the thread providing detail on the encoding schemes used by Lacrosse weather remote sensors. Here an analysis spreadsheet I used for decoding of the bits: I think the transmission can sometimes become corrupted by what I'm guessing is general radio frequency noise. Sometimes when watching what is coming over the 433Mhz receiver I'd see other pulses coming in that were not matching up with what the TX7Us were sending. Perhaps there are other devices in my neighborhood that are sending signals on the same frequency. In some cases two TX7U sensors would end up sending their broadcast at close to the same which become impossible for the software to decipher. I'm using a RXB6 RF 433Mhz receiver. I'm not sure if this is a best in class receiver out there and my from experience the walls and floors in my home seemed to limit it's range. I ended up placing the TX7U sensors fairly close to the Photon receiver or made sure there were as few obstructions as possible between the two devices.
I found that creating an antenna of the proper length helped ( Make a Simple 433MHz Antenna for Long Range Use ) improve the success rate of decoding the transmissions. While I was making progress on decoding of the signals I was hitting a road block on getting those signals into the micro controller for decoding. I was hoping to use one of the existing 433mhz libraries that would make it easier to accomplish this task: VirtualWire, RadioHead, and RCSwitch. But I could not able to make any real progress in using these libraries. Then a miracle happened. Or at least what seemed like a miracle. I discovered a far more skilled enthusiast, Emanuele Iannone, who had solved the very problem I was stuck on. He coded from scratch a library which could read the 433mhz Lacrosse weather sensor transmissions. This was an amazing stroke of luck as it would have ages for me to understand how to do this on my own and I might have just given up on the project. The code The main engine of my code, TX7UReceiver.ino, is Emanuele's code. From his starting point I added methods 1) to provide ability to configure readings for multiple weather sensors, 2) calculate the dew point, and 3) post to both Weather Underground and ThingSpeak. The Particle cloud methods were added to as needed to interact with the Particle cloud: Paritcle.publish, Particle.variable, Particle.subscribe. After figuring out how the engine worked I added lots of comments and renamed variables to make the code easier for the 'future me' looking at this a year from now to understand. Emanuele's code is using a rolling buffer and lots of low level bit shifting wizardry to decode the analog signal into the sequence of bits that represents the temperature and humidity readings. Wish I could say it was easy to grasp how that wizardry worked but once I did I wanted to write it all down so it would not slip away.
Weather Underground API Here is an example of what that the Weather Underground post looked like: Refer to the Weather Underground 'PWS - Upload Protocol' for the specifications for this post. You'll need to register a Personal Weather Station to get a Station ID and a Station Key: Personal Weather Station Network. I then used the HttpClient Particle Library to perform this post. I initially tried using the TCPClient, which is built into the Particle Firmware, but could not get it working. ThingSpeak API You'll need to sign up and c reate a ThingSpeak account and then configure a Channel. There are eight data fields per Channel in Thingspeak so that meant it was possible to record up to eight separate data points. I have three TX7U sensors and each one had a temp and humidity so that is six datapoints total. ThingSpeak Channel configuration I used the TCPClient to peform GET update. It ended up looking something like this: Sensor IDs Each TX7U sensor has a two digit Id that is randomly created when the battery replaced. I'm not exactly sure how this assignment is orchestrated but this ID is needed otherwise it will not be possible to associate what reading is coming from what sensor. In my code there is a string variable 'lastIdsRead' that contains a rolling string of all the successful decodings. The temp (F) and humidity (rh) values following each ID. Since 'lastIdsRead' is a particle variable it can also be accessed through the Particle cloud console. This is the easiest way to get that info without going through the bother of connecting the Photon to a serial USB port. Debugging The other reason for using the console is to view all the Serial.println detail of what is going on during the program execution. This detail can only be viewed when the Photon is connected to your machine via USB. This output is not meaningful until you have a handle on what the code is doing.
The only way to perform this tweaking was to watch the output from the console to see how often a pulse was able to be decoded. Crashing of Photon One of the most aggravating issues was the Photon going into red flash 'SOS' mode. I did not have any real clue as to why. After hours of trial and error it turned out one of the culprits was a Serial.printlf statement that was doing something 'bad'.But this it was the only way I knew of to get insight into what was going on while the code was executing. Configuration I ended up with an approach that relied upon hard coding across an enum, a method, and a switch statement. The configuration associates a Photon cloud-aware device name to an enum. That enum is then used in a switch statement that 1) associates that Photon with it's Weather Underground and ThingSpeak credentials, 2) maps the ThingSpeak fields to the temp or dew point reading for a particular sensor, and 3) identifies which TX7U sensor ID is the outdoor sensor. The outdoor sensor's readings are then sent to Weather Underground.The hardware aspect is pretty simple but things got tricky when it came to the software and debugging which is the reason I gave the project an intermediate rating. I also liked how this project gave some 'old school' devices ability to be cloud enabled. In the future I'm hoping to find a way to improve transmissions being reliably decoded up over greater distances. And maybe add more sensors but this would be dependent upon having the decoding logic for the particular device available. There's a problem loading this menu right now.

Margaret Blye Net Worth. I know how to find and decode the transmission from the sensor using Audicity and a spreadsheet to input the bits. But I'm feeling quite intimidated by trying to go to the next step of figuring out how to code something that will monitor the transmissions, detect when a pulse is sent, and then find the bits of that pulse that contain the temperature or humidity.
I found an example of how to do something like this and it's looking it will be quite involved: Practical Arduino - The Book - WeatherStationReceiver I was naively hoping that this going to be a much easier project because there would be libraries that would take care of most of the low level work. But now I'm not so sure. I've played around with a few of those libraries like VirtualWire, RadioHead, and RCSwitch but they all failed to return any data. Is there a 'library' way of doing this. If not could anyone offer some general general guidance on how to go about doing this. So to some extent I'm trying to gauge if this might be overly ambitious for my skills. Used the poor mans 'scope' to figure out what is going on. Discovered that about every 57 seconds a one second pulse is sent. Here is a closer view of that pulse with the sections that contain the data bits of interest: Here is further zoom of the temperature section showing the 44 bits that Lacrosse is known to send: And here is getting the 44 bits from that section: Here is a spreadsheet I made that takes in those bits and calculates either the temperature or humidity: I can provide more detail on how the decoding works if that will help. Thank you. There is a ton of stuff out on the boards about 433Mhz and for someone with a very little EE background sifting through all it to come up with a coherent big picture view is not easy. I just discovered something that I hope will be useful for that learning: RF Basics, RF for Non-RF Engineers - Texas Instruments I'm going to start diving into some of the details. It is looking more and more like the 'easy' (i.e. lazy) way to accomplish this task does not exist. But I have no idea if this also holds true for the TX7U. It also gives invaluable insight into how to do the decoding. But it was not exactly matching up with what I saw on the TX7. This post decoded LaCrosse TX2U temperature sensor 433MHz showed how to decode the temp from the data bits for my TX7.
And I just took some guesses to figure out how to get the humidity. Hope this is at least a partial answer to your question.Also replace the batteries as this might generate a new random sensor number. I've been trying to honor that interest by spending hours and hours over the past few days trying to learn up on RF. This is going to sound crazy but a few hours ago this gentleman Emanuele Iannone just created a library that works for my TX7NU!! He build an impressive.Net project that works with the Lacrosse WS8610 base unit. A few days ago I contacted him about trying to decode the TX7NU sensor units which come with the base unit. Several days later he had it figured it all out. Library: It's not supposed to be this easy. Saved me days if not weeks of trying to figure this out on my own. Hope that others can benefit from this work. It was very mind bending exercise to try and grasp some of the programming concepts I've never been exposed to before. All sorts of bit shifting and binary manipulations that I've never run into all my years of coding business applications. I added a bunch of comments to it try help and bring it down to my level. I also renamed a bunch of the variables but not because I was trying to take over the code but instead to help with my exercise of trying to learn the code. Im thinking this code works differently than some the other decoding techniques because it is triggered by a long delay in the signal. That delay is the marker sent by the weather sensor to indicate that it's data has been sent. When the delay occurs then the contents of the buffer is evaluated by the code. The buffer is 88 bits long with each item of the buffer being loaded with the time value in microseconds when the 433Mhz receiver data pin interrupt occurs. This buffer is continuously written to and is constantly being rolled over. When the buffer gets evaluated the starting index is what ever index it was being loaded when triggering delay occurred.
If that delay is occurred when when index 12 was being loaded then indexes 12 to 87 and then 0 to 11 are evaluated in order. This concept of what I'm calling a rolling buffer is not something I'm used to. I'd expect to see an array filled up from index 0 until the end and then read from position 0 to the end. And then I'd expect that array to be cleared out each time it's filled up again. But not so here. And it works brilliantly. I'm guessing this is good coding practices for embedded systems where lightweight and speed are primary considerations. It took me awhile to understand that the code was evaluating all the time intervals for a certain pattern. That pattern is that a LONG or SHORT interval must be followed by a FIXED interval. This pattern must exist across all 88 timings in the buffer. Then I everything started falling in place. The breakthrough for me occurred when I dumped the entire buffer each time the triggering interval occurred. Dumping it the console was very wrong as there is no way the processor could keep up with the interrupts blasting away while also displaying the huge stream of data to the console. I'm guessing some other badness was also happening here with threading and memory that I don't even understand. But the dumping made it clear what pattern needs to be. Then I just commented that dumping code out. I have mention I running this Photon so you'll need to fix the interrupt to get it working on Arduino again. Photon has built in wifi and can handle more libraries so it's alot easier for my skill level to post the weather data to a url. Also should mention that Emanuele's code has now been tested on my side with TX4 and TX7 sensors in addition to his TX3. Hi, I have a problem with the specific example with an OEM 433 sensor. The readings is correct but are not getting every time the device is transmiting the data. I think that it has to do with the sync period but is there a way to find theese tresholds. Thanks in advance.
The readings is correct but are not getting every time the device is transmiting the data. Capture the signal into Audacity and then you can zoom in and measure the timings.

This supports the Ambient weather F007TH see chapter 2 in the RFXtrx User Guide for the list of supported sensors.
Is it simply that the code for decoding the sensor just does not exist on the Type 1 Firmware on the RFXtrx433 and not a technical radio limitation?
