Virtual data source, disable periodic update
hi, not sure if this is the right forum, but here goes...
i have some meta points which SUM a real data point (modbus) with a virtual data point (used to provide an offset for calibration purposes).
Because i needed precise update timing (for my data logging), i used to CRON to produce the result.
What i would rather have done is have the meta point update on context and use the polling interval of the real data source as the trigger (i have quantize) selected.
thing is the internal data point will also cause an update and this is undesireable.
it would be nice if i could enter 0 update period or disable it in some other means.
i thought of entering a very long update period, but thats no good.
really need to disable periodic update.
