Cracking the Power-One Aurora Desktop PVI wireless code

[2ndBillericay]

Has anyone who is using the Aurora's wireless card managed to crack the code that is sent to the PVI Desktop display.

We bought both the wireles transmitter and the display unit but want to build another simple remote unit to display the data.

Thanks

See if this software finds the transmitter and its encryption:-

The communication between the inverters and the Aurora PVI-DESKTOP is carried out through either RS485 wire link or radio link at 868 MHz. In both cases the communication is supported by an Aurora proprietary protocol.

says 915 MHz but I assume that's the US model. It also mentions Bluetooth - not quite sure what that's for. Whatever, it doesn't seem to use WiFi.

TellStick is a generic radio receiver useful for this kind of thing. But I'd guess if you know enough to start protocol analysis with one of these, you probably know enough to build the (pretty trivial) hardware yourself too....

Hi Guys, thanks for the discussion. We ahve the Aurora Radio Card installed in the inverter and it is transmitting at 868.26MHZ so unfortunately the TellStick is on the wrong frequency.

I have tried using a RM22 with my audrino and a Jeenode on the 868.25 frequency but have failed to find the signal - probably doing it wrong !! - as i am an insurance proker not a electronics whizz :-(

Any ideas would be gratefully received.

I think i will be purchasing the Desktop display unit for inside the hall (the previous one was sent back to another supplier as the display failed) but i would like a simple 3 line LED display on the outside of the building.

Thanks

I forgot to mention that the wired protocol is available on the internet as Power-one have released it but not the wireless bit so with luck they have not changed the propocol, just packaged it up for FR use - lets hope.

You might try finding a local radio ham with a high-end scanner. Just hearing the signal and maybe using a built in spectrum analyser or whatever would give a warm and fuzzy feeling and may well give an idea of the modulation (simple on/off, frequency shift, whatever) being used.

You could try a Wattson  universal display (and, you guessed it, the software is called Holmes)

Any chance of a link? A google search has been fruitless so far.

has anyone managed to hack the thing so it stays on - whats the bloomin point in a display that doesnt display? I can understand the hard wired screen off with it on battery power - but why forced off when plugged in?
