at last, the kind folks in Resol sent me the protocol specification for vbus with openwrt and rrdcollect and rrdcgi, I can now graph the pumps and temperature information of my solar water system. There is a bash script that collects from the serial port, decodes it , and then outputs the values to a file that rrdcollect parses. All good, some holes in the graphs, probably a bad awk in my script, to be investigated. Once it's working reliably with no holes, I will try to post graphs here, somehow EDIT: Now there is a google group http://groups.google.com/group/resol-vbus EDIT: I wrote a utility to parse the data, seems to have gotten lost in the group, it's here https://code.google.com/p/vbusdecode/

yet another way for dazzle and heron :-(
ought to be exactly what i've been looking for for ages ... if only i had the prior knowledge you seem to assume i have about 'build.sh'. presumably, one does it as ./build.sh build at first, but then does one do load, then install? or install then load? or just install?
and for that matter, what does one do next? presumably reboot, but then does one modprobe em28xx-new, followed by plugging one's device in, or something else?
thanks and cheers, map

to be honest, the em28xx support it not the best, you typically need to insert usb stick after book and modprobe, there are known problems with doing this during boot (it doesn't work).
I got a wintv nova td, which has 2 tuners in it , which allows me to watch one transponder (here that equals several channels) and record another. it is supported by heron without any special requirements and works everytime. my dazzle stick is now used in windows and osx instead of linux.
