**** Expected to read 99 chars; got 0 instead

[Clive]

I know this has been discussed before in other threads and I have tried the suggestions offered but so far I have had no luck in solving this.

The station had been logging fine with the Raspberry Pi and all of a sudden its started throwing these errors.  I've just powered down the entire station and console, for an hour and turned it all back on. (Removed solar panel, backup batteries etc) 

Jul 18 22:08:05 raspberrypi weewx[4235]: VantagePro: LOOP #1; read error. Try #1

I’ve had power issues on the IIS itself, basically some vandals smashed the solar panel and damaged the antenna.  I'm trying to solve these issues but now I'm having comms issues between the console and the Pi.  Could these two issues be related? 

Its reporting a temperature of -73.3°C to Wunderground :/

Anyone any ideas, as I'm at a loss ????

In further, the Pi is gathering the data from the console as WeeWX is reporting the Barometer and Inside Temperature fine.

As you have already figured out, the read errors are a problem between the RPi and the console, and have nothing to do with the ISS.

It looks like weewx is recovering from the errors. However, there does seem to be a lot of them if the little log snippet you included is representative. 

Usually these errors are caused by the USB connection. Are you using a Serial to USB converter? I know it was working properly before, but it's worth trying some others.

Also ferrite coils can help.

As for the weird WU temperature, that could well be a problem with the ISS. What is the console showing? Try selecting MIN on the console and see if it too shows -73.3C.

Sorry for opening an old thread, but yesterday I had the same experience.

I installed a fresh copy of weewx and started from point zero.

I found out that weewx changed a bit in two years ;-)

But after all O succeeded in installing weewx and motion the way it should.

I started my pi without problem and the data started downloading from my DVP2 console.

But after a while I discovered the above problem. Could it be that my cable broke just at the moment I installed a new copy of weewx? I could not believe that and reinserted the SD-card with the two year old version of weewx. Everything went just fine without any errors.

So in my case it is not the cable but somehow or somewhere a misconfiguration of raspbian or weewx.

What can I do to find out what causes this problem?

I have to say that the old SD-card was a normal size SD-card and the new one was a micro-SD with adapter. Could this be the problem?

I have the Datalogger clear, weewx restart, nothig help! Can i Help me? The connestion to the Console works, Time its wright. With command wee_device --info i can see the Data on the Console. The MQTT can sometimes read data, but is then repeatedly interrupted.

[Thomas Keffer]

Hello, Stefan

1. Has your station every worked? Or, has it always been like this?

2. Could we see the output of wee_device --info?

3. Try reseat your logger: pull it out, then put it back in.

4. Also, check your USB connection. Make sure it is fully seated.

Hey Thomas

1. Yes the station ran flawlessly. Suddenly it started with this mistake
2. Yes see all data on the console
3. I still have to test
4. Connection is OK
