Timeout errors with WMR88

[Scott Picton]

I've recently got my WRM88 running with WeeWX. I'm running it off a ASUS Tinkerboard, loaded with DietPi and a few other services. I installed via apt (having to use the old gpg keys).

For the most part it appeared to be running well, however I have been getting random timeout errors. Sometimes after hours, sometimes after almost a full 24 hours. After the timeout message I then get pipe errors each time it tries to read the station. If I unplug and replug the usb, then restart weewx then all works again for a while.

I had the same weather station running fine on a RPi with wview and didn't appear to have any issues.

I've got debugging on, but really it didn't seem to show much more information than without?

Here's the log:

These are often caused by an inadequate power supply through the USB connection. Try using a powered USB hub if you have one. Or, a bigger power supply for the ASUS board. See if that helps.
