Hello.
Using several flows to read data from Modbus device -> data are stored in influxdb.
Using CronePlus or inject node to trigger the read with a modbus-getter node. Read durations are different -> some 15s / every 15min / 1 time per 24h
Issue:
Getting problems when i would like to collect the data 1x / 24h or every 15min - looks like the device is in sleep or not ready.
Therefore I would like to implement a function/query to secure the data are read and stored in influxdb.
How could I integrate a function or something else to check?
Please - need some help for a smart way.
Thx.
Following flow as an example.
