Hello mikhail
i think it would be very nice to make the data store interval setable for each channel, currently the setting will affecting all channels.
the reason is sometimes some data are more faster and critical than others (for example, need to be stored every 1s), if we can only set the interval for all. the database will getting big very fast.
and for analog valves, if will be nice to set hysteresis, to reduce the database size.
