I've searched on this and other forums and found alot of conflicting info and various solutions that have been discontinued.

I have a VP2 cabled version, with the 6 pin RJ-11 jack under the cover labeled COMM. I do not have the console.

What would be the best way to connect this to a Raspberry Pi to run the WeeWX software ?

I'm very comfortable making custom cables if needed.

Can I supply power to this using the RJ-11 Jack ? Even the pinouts I found have varied from source to source.

My ISS Transmitter has a Prod # of 6327C.

Thanks for any guidance.

It does not come installed on the Mac you need to install it whilst in Terminal. Use the command brew install dfu-util or sudo apt install dfu-util depending on which environment you are using in terminal mode. I used the first command. It goes out over the internet to download and install the dfutil software.

Thank you. I finally did it after undertaking various internet searches about installing Homebrew 'software'.

Must say, that is absolutely over the top nuts of Ecowitt to expect Joe Public to be able to update their weather station firmware on a Mac. Nuts.

I bent the spikes inwards, but since there's nothing stopping them from rotating in the little rubber sleeves I expect they'll get pushed out of the way pretty soon.  I'm going to have to make something a bit more durable using a large hose clamp.

I've only had my WS90 for about two months. Like you, I found the rain gauge function to be a bit hit and miss but the latest 1.5.6 firmware seems to have fixed it pretty much. I had the newer bird spikes on my WS69 which died a natural death after 6 years or so. The newer spikes kit came with two bands and some extra spikes and mounts which allowed me to add them to the WS90. The tension band is very taught and I haven't had any birds come visit yet. The spikes are the newer zig-zag type as well.

EDIT -  I also installed the 12v power adaptor on my WS90 as it is mounted high up on my house roof. Works perfectly though the low battery warning on the console is a continual annoyance. The web page for my eccowit site also lists the low voltage as a warning in the battery panel but I have renamed it so as not to be a bother...

Thank you. I estimate I use the Terminal.app once every 5 years

Its now accepted my password.

It comes back  sudo: dfu-util: command not found

The file is unzipped: WS90_V1.5.6.dfu

Thanks for sharing!

I especially liked the sunrise behind the Vantage Pro-2.  It kind of ties into the Sun image with a flare.  In this case the shield to protect the camera from the intense solar radiation is none other than the VP2 itself!

Anyone else?
