Hi, Consider also to use an Arduino connected to your inverter using TA sensors. Then you can use Emoncms, that is a cms (lamp) focused on log, elaborate and show power consumption/production data. It's opensource and you can use the free cloud version (emoncms.org) or download it and install in your own server. They design also hw stuff (arduino related). The main project is : www.openenergymonitor.org Regards M Il giorno 26/feb/2014 10:20, "Bret Busby" <bret@busby.net> ha scritto:On Fri, 31 Jan 2014, Scott Ferguson wrote:On 31/01/14 13:38, Bret Busby wrote:Hello. I am wondering whether anyone on this list, has any knowledge or experience of software that runs on Linux, preferably Debian Linux, for monitoring/logging electricity output from a photovoltaic inverter. In searching in the Debian packages facility, the only package that I found, was solarpowerlog (0.23a-2), for Debian Linux v7, and the package is apparently for only Solarmax inverters. I am seeking software that will interface with Rewatt inverters, which apparently have an RS232 interface socket. The inverters come with a software disk, the supplied software apparently being for only MS Windows.I'm not familiar with that inverter, but you should be able to get general logging data from the port. If you're *very* lucky it'll have telnet console. Point Wireshark at the interface:- # apt-get install wireshark wireshark-docDoes that work with (does it scan for), or is any other application available that scans for, wireless signals? I have "wireless carrier frequency 433M (assumed to be 433MHz)" Two transmitters, so I am wondering whether a utility/application exists, to scan for the two separate signals and retrieve the data from the signals, so that the data can be processed. -- Bret Busby Armadale West Australia ..............

Hello.The Arduino system, from looking at the web site, seems to me, to be a system that needs to be wired into the inverter, which would require an electrician to connect it, and, possibly, depending on the degree to which the inverter needs to be opened up to wire the stuff into it, invalidating the warranty on the inverter.
It appears to be overly complicated, relative to what I seek. I have the wireless transmitters for the data from the inverters.I have some weird and difficult to set up (we have managed to get one of two, working, as much as it does work) lcd monitors of the data from the wireless transmitters. The lcd monitors ("data logger" "receiver unit" things) do not have sockets for data output; they receive the data transmitted, and, do what they do with it, which is not as much as I want.
I have the manufacturer's RS232 leads (which I am not using, as they are not long enough to go from the inverters, into the building without an exposed extension connection).
So, what I need, is a means of receiving the wireless transmissions, from the wireless transmitters that I have, into a laptop computer, whence I can manipulate the data.
