i was looking for a device that could measure the rotation of my
ferraris energy meter. There is commercial ones that are quite expensive or don't really show the detailed energy consumption.
I think also CHDk with the motion detection could work as smart meter. I am not really into the software and scripting and just wanted to post the idea. So if anyone has interest and ability of programming I would be happy about using such program.
I am imagining something like that the motion detection reacts on the red stripe on the wheel everytime it passes by. You could use the AF light as light source to be able to monitor in dark ambients. I guess the process might be more stable if the motion detection color is only red.
Instead of taking photos each time the red stripe passes by only a log could be written. In best case this log is evaluated by excel showing a power consumption graph.
I hope anyone else likes this idea and looking forward for your comments.
