Hello together,

I am new here in the forum and would like to introduce myself briefly:

I have a Davis-Vantage Pro2 as my weather station and have recently purchased a Pro2. Now I would like to use an external USB stick. I bought a 32 GB mini stick from Intenso that was pre-formatted with FAT32. Unfortunately, it is not recognised on either port. Today I will try to format the stick as EXT3 in the hope that it will work.

What else do I need to consider or rather, what am I doing wrong?

Thank you very much for your feedback.

You might find some info in the following thread?

Thank you for your reply.

The link to the post was at least helpful. I used my iMac to format the stick with FAT32. Here, all partitions of the stick are completely deleted under MacOS. And here the Meteobridge seems to have a problem. I will get a new stick and then try it "virgin".

When the external USB Stick is equipped with one partition that holds a FAT32 file system, Meteobridge should be fine to make backups to that. This is also the standard layout new USB sticks come along with. But to my knowledge PRO2 does not provide the option to backup its database to an USB stick nd also does not support to use an external USB stick as primary storage.

When I remember right, PRO2 does backups on the SD card and you can pick it from there by accessing the "backup" folder Meteobridge provides to your PC-network as a SMB share.

Too bad. Just plugged a brand new stick (intenso mini USB) into the front port and unfortunately it does not work.

What are the ports for then? A Meteostick is not needed.

I am now trying to transfer the gz files to a Fritz NAS as I prefer an automated process.

even though I don't have a MB Pro2, as long as the MB Pro2 has a USB port, you should be able to mount this USB device into the MB file system.
And you should be able to modify (or create from scratch) the backup script to write to the external USB stick.
This may not be the "default" method for the MB Pro2 (meaning not covered by the scripts it comes with) but should still be feasible.
At the end of the day openWRT is a Linux variant, and what is possible with a (meanwhile) old MB Pro or a MB on RaspberryPi should in principle also be possible with the MB Pro2.
When you are familiar with Linux and SSH, you can connect to your MB and find out as what your USB device is recognized (after being plugged in ):
ls /dev/sd* -l
should show you all "special devices" (sd) what they are called under Linux and external USB devices are all treated as sdxn
x= a, b, c - just a "numbering", n=nothing, 1, 2 ... - the number of the partition on the external device.
Usually with no other external device connected, your USB device would appear as sda or sda1
e.g. with
mkdir /tmp/mnt/data/USB
mount /dev/sda1 /tmp/mnt/data/USB
(the data on) your USB device should now appear in the exported network share under \\METEOBRIDGE\data\USB
(this is assuming that the MB Pro2 has the same setup of its file system as the NANO, MB Pro and MB on RPi have)
Make sure your external USB device is FAT32 formatted.

If there is a common need to backup to a connected USB stick, I can put this as an option on my PRO2 feature list.

As Meteobridge can handle multiple weather stations in parallel any USB port might come handy for additional USB connected stations.

Typically for connecting weather systems where USB or RS232/RS485 (with USB converters) communications are used.

Yes, please…
