If it’s working, looks good. Couple of points though:
It looks as if you have a split-phase system with two mains. For purposes of monitoring, most folks are interested in the combined power in, generated, used, etc. The calculator/script system can be used to add the two phases together and upload as a single measurement. That saves you from adding them in influx Queries and also reduces the volume and complexity of upload and storage.
Util_Amps Amps = UtilityMain_PhaseA + UtilityMain_PhaseB
That cuts the whole thing in half. You will appreciate that if you try to upload a bunch of history or if there is a communication or influxDB server outage that causes a large backlog to upload. It will also simplify your queries immensely because you won’t need to query two values and add them together to get the total.
Update: Also, it looks as if you have solar generation. If you are interested in your consumption, as opposed to the net, influx is a good way to do that. It can’t be done in the IoTaWatt because it requires integrating the individual intervals. Assuming your mains go negative when exporting, your usage would be:
Usage Watts = UtilityMain_PhaseA + UtilityMain_PhaseB + SolarGeneration_Phase_A + SolarGeneration_PhaseB
