Hi,

When connected via USB, there is the ability to download the image.

How could this be done with the raspberry via wireless M Bus? The image when downloaded via USB is 20kb so this should be feasible.

Thanks,

John.

Hi, sending other data then the meter readings is not implemented.

The M-Bus (and also the wireless M-Bus) is used to transfer the meter readings. (see http://www.m-bus.com/files/w4b21021.pdf)

Downloading an image via wireless M-Bus would mean to implement a private protocol to transfer the 20kByte data package from the sender to the receiver.

Best regards ffcrg
