Yes, you have to be very careful to use the correct frequency and follow the rules of the radio communications regulator. American laws tend to be somewhat lenient in this area than European ones, but in any case, breaking the rules can result in fairly severe penalties.

And I'm!
All units sent to USA or AU use LoRa modules approved for those countries, as also units for the European market are fitted with LoRa modules approved for EU.

Well, that's what I know about you! But this was meant for Zac!

Hi Zdenek,

Yes, I have understood that your post was for Zac, I just took the opportunity to reinforce the info that changing the setting on config_options.h on the software doesn't turn an EU module on an USA / AU module.

Thanks for being always attentive.

Werke that is a good question, looking at the temperature chart in Cumulus the indoor temp is flat as well! It is the yellow line:

   

Since that is being recorded at the receiver it must not be a radio issue, clearly it's a wifi issue with my house network! Seeing the rf efficiency number go up and down made me assume that was the cause, I just updated to the latest firmware and although it started out in the single digits after the reboot it is climbing, currently in the mid 30's after about ten minutes. I dont have any flat spots in the last three days that cumulus displays and I don't know how to look at data older than that, other wise I could check and see if the wind is also dropping out.

Thanks for trying to help, funny just a simple suggestion makes the issue crystal clear!

The receiver has been sitting unhoused since I got the system operational, my plan is to put it in an enclosure with a ups and the raspberry pi that hosts cumulus, then change the connection between the two from wifi to usb, that way I'm not relying on my network.

On another issue, we got a strong wind gust a couple of days ago, Cumulus recorded 45 mph but my weather underground page shows 69 mph? Looking at the other local stations my gust number is an anomaly, temperatures and other data are normal. 

Cheers, and thanks!

Well I changed to the USB connection to my raspberry pi and now I'm losing even more data, tx efficiency is in the single digits, perhaps it is a radio intereference problem. Yellow is the pressure, the other traces are temperature, windspeed, and wind gust, they do not track, as I noted in my last post:

   

I'll leave it on USB for a couple of days, the pi and receiver are quite close, the I'll try going back to the wifi connection and see how that works.

Thanks for your help in advance,

Zac

Hello Zac,

I never saw an issue like that with such persistence, so I'm without any clue about what is causing it.

On the receiver, there are two LEDs: the COMLED and RXLED. The RXLED should blink whenever the receiver get a datapacket from the TX unit, the COMLED should blink every second or two, whenever there is an active connection to Cumulus.

How are those LEDs behaving?

Try to change the receiver power supply, some power supplies are too noise.

Hey Werke, I changed out the power supply on your suggestion, it powers the Pi and a the receiver is connected to the Pi via USB for power and data, I haven't seen any drop outs since the change so perhaps that was the issue. With the usb data connection with the Pi it was missing a lot of data, worse than I have ever seen it, so now with the different power supply (an LG wall wart) it has no dropouts in about 60 hours.  I don't have the LED's installed on my receiver but sounds like they could be helpful so I will solder some in.

Thank you for the help and I will keep an eye out for any more issues,

Zac

Hi Zac,

From what I can see on your wunderground page, seems there isn't any data drops since March 6.

No problems since I changed the power supply! I'm consistently showing in the high 90% rx efficiency, what a simple solution, wish I had tried it earlier... Thanks again Werke for your help, I've got a ups that I'm going to try out and eventually put the receiver, pi, and ups in an enclosure together if they prove to work effectively on the bench.

Cheers,

Zac

It seems the Nano in the transmitter has died, it crashes an hour after being reset and stops transmitting, decided to pop in a new one but I cannot get the software to compile. Surely I'm missing something obvious but no idea what I'm doing wrong. I'm using the 1.6.21 Board Manager, IDE 1.8.19, the libraries that came with the firmware, I've tried the three different options for processor.
 

Code:

fork/exec /Users/user/Library/Arduino15/packages/arduino/tools/avr-gcc/4.9.2-atmel3.5.4-arduino2/bin/avr-g++: bad CPU type in executable
Error compiling for board Arduino Nano.

I'm on a new machine (macbook pro with the M2 chip) but tried it on the old one as well, so weird, I've obviously had it working before!

Any suggestions? 

Zac
