Resol VBUS success
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/
