Topic: Connect to Nano SD with multiple instances (of WeeWx for example)

[lobsterman]

Is it possible to set things up so that more than one instance of WeeWx (or any other program that uses ethernet) can access a NANO SD on a Davis VP2? I know the Weatherflow devices broadcast via UDP which allows any number of listeners but my networking skills are insufficient to know if there is a similar alternative using TCP/IP.

No.

If you invest in a WeatherLink Live then you'll have exactly that... support for a local network API where multiple devices / software can have at the data simultaneously. The WLL connects to your network via Ethernet or WiFi.

WeeWX supports the WLL API via external driver.

The WLL API is supported by the major weather software options; Cumulus MX, Meteobridge (standard, Pro Red, Pro Black), Weather-Display, and WeeWX. Run the all at the same time and even multiple instances of the same one, on the same device or different local network device. Simple setup and very powerful option to test. Makes data migration easy if moving from one system to another while not losing data on other live system. Good solution to have a backup upload to your online services.

Thanks, interesting. So I would not eliminate my pricey NANO SD using that box then? I'm not entirely sure of the network config when using it. Will study their docs some more.

Do you use one? Satisfied with it?

I've installed few, but I don't have one myself.

It is up to you if you want to eliminate the NANO, but I'd keep it. The WLL is independent. It doesn't need your display console at all.

The WLL receives data directly from the sensors. Then the WLL makes the data available over the local network and it can also upload itself directly to Weatherlink.com.

That thread with the graphics of the different options is really useful, many thanks for the pointer!
