Losing Connection
« on: July 24, 2018, 06:47:34 PM »
WeatherCat is losing connection to the Vantage Pro 2  console every few days. It's always in the evening. The system Console log reports "WeatherCat: sensor failure" and then "***WARNING*** WeatherCat was not able to fetch all the weather data from the hardware after repeated tries." It continues like this until I restart the computer. The Vantage Pro 2 console does not display any error message. All physical and electrical connections are okay.

Davis Instruments Vantage Pro 2
WeatherCat v3.01 Build 5
Mac OS X Yosemite v10.10.5

How do I find out what sensor, if any, is failing?

Grand:

Go to Tools | Live Data in WC. It will display your sensor errors.

Also, this is what the manual says: If there are a lot of sensor errors then the problem lies between the weather station and its sensors – if wireless try repositioning the station, if wired, check the connections. In all cases it’s worth checking any batteries.

Sensor errors shouldn't cause lost connection. (Re: Losing Connection)

Dear Grand, Blick, and WeatherCat troubleshooters,

WeatherCat is losing connection to the Vantage Pro 2  console every few days. It's always in the evening. The system Console log reports "WeatherCat: sensor failure" and then "***WARNING*** WeatherCat was not able to fetch all the weather data from the hardware after repeated tries." It continues like this until I restart the computer. The Vantage Pro 2 console does not display any error message. All physical and electrical connections are okay.

Blick has given you the correct place to check for sensor errors within WeatherCat.  It is also possible to check the status of a sensor within the console itself.  Check the troubleshooting guide that is chapter 4 in my old Davis console manual starting on page 34 or so.  The manual is available online if you have lost your copy.

However, if WeatherCat is reporting connection problems that go away when your Mac is rebooted, most likely the problem is in between the console and your Mac.  Have you tried the troubleshooting tips on the WeatherCat Wiki?

The Ferrite clamps are highly recommended.

Finally, if rebooting makes the problem go away, it could be something on your Mac itself?  If this is happening every few days could you be running short of memory?  I have to reboot my Mac every 3 days to make sure there enough free RAM.

Let us know what you uncover.

Cheers, Edouard
