For historical data, I wonder if it’s already possible to set up an array of variables within a flow. For example to take running average of x latest lux values. In the example posted here, I solved it by creating 4 variables, lux_neg3, lux_neg2, lux_neg1 and lux_0.
I believe creating a guide or standardised flow setup for this would be preferable over using data from the Event collector in many cases…
