I know this could be simply too trivial, but I want to know if there are best practices associated with this situation.
I have a sensor giving temperature (bme.temperature) and humidity (bme.humidity). I’m going to add dewpoint, which uses both.
Should I make a variable ‘temperature’ and reference that, of should I have another (bme.temperature) measurement?
It seems to me that efficiency is favored by using the external sensor once. It seems like referencing a variable should be a much smaller event than reaching through wires all the way over to the BME 680.
