Hi,

Writing to storage is not direct to SD so could not hurt the SD.

What i do in this case is use a KNX interface of Schneider MTN670802 and set it to impuls counter, it then counts the impulses internally and you can write the counted values over x period to the bus on a set interval.

In the controller i get random values like 30, 40, 35 depending on the number of counted pulses in the set period and i sum them to the old value, this way you don't need to process every puls on the controller but you do it in batches.

But still you need a storage for the counter. Do you store it on SD card?
Because both options are wrong in sobe way
GO - backup and restore is impossible
SD - changing of SD is complicated

Some mix of both? I mean compare GO and SD and higher number wins seems to be a good choice.
