Learning Flux instead of influxQL for external Query? Clients?

Hello @Pete0815,
Problem 1:
What do you mean by mistake because of the timestamp? Which timestamp would you like to use? Can you please provide a numerical example?
Problem 2:
I’m not sure why that isn’t working. Can you please share some of your data with me? You can export a small out with the UI easily. Not to be too redundant, but I think using the UI might help you debug some of your Flux.
Here are some blogs that could be useful to you:

Here are all of my blogs in case there are others that are useful as well:
