Hi Michael, I have been dealing with the same problem in our industrial iot project.In such special scenario you mention above where internet connection is limited and poor .I have used your first method, query local influxdb and post it central influxdb when internet connection is available.I dont think that kapacitor has appropriate node right now.At least I couldnt find it in documentation
