I'm trying to send notification if humidity reported by Netatmo weather station goes below threshold. I only started to play with Node-Red last week and have my lights working according to sun events so far, so this is the second automation with Node-Red for me.
I'm using the Netatmo palette and the "get measurements" function. I have successfully set my account there and identified the station. Couple of things that are not clear for me at the configuration are Scale and Limit.
Limit: I assumed that this should define how many results I want to get. As I want only the latest (i.e. the current) I set it to 1. Interestingly, Even if I set this to 1, with 1h Scale there's more than one result.
Scale: max, 30min, 1h. If I set 1h, does it return average values of the last hour? I noticed that it does return a bit different values depending on the set value. No matter which value I use for scale, none of the returned values are the actual current values.
So could someone explain what do these mean and why do I get wrong values? These values are not even close to the current values measured.
