I spent far too much time last night adding daily high and low temperature display to my Raspberry Pi node red hummingbird feeder monitoring UI.
So many limitations and quirks to work around!
First, Influxdb does not have a “start of day” function, so I had to do that in a node red function. I need that so it doesn’t include yesterday’s readings for today’s highs and lows.
Then, I realized everything is in the UTC timezone, which gives a different meaning to “today”, so I had to adjust that on both ends: in node red AND in the influxdb query.
Things got personal, so I couldn’t quit!
But look! How pretty!
ultimately it was only a few hours, but for that tiny bit of result I was thinking it should have been like 10 minutes! Maybe I need to lower my expectations
