Boiler on/off detection from Total power consumption

Third party integrations Node-RED
,

Hi,
I would like to create a routine in node red to understand when the boiler is on or off (to calculate relative consumption).
Having at home energy meter a consumption detector and knowing that my boiler when turned on consumes between 58W (fluctuates between 50W and 65W), my idea is to:
Take every 10 seconds the total consumption value of the detector, check if in those 10 seconds there was an increase in consumption between 50 and 65W. If yes, sensor.boiler = on otherwise sensor.boiler = off.

How can I do this? Thank you very much

If it’s only 65 W on your total consumption then I believe you will get a lot of false positives.
65 watts is not an uncommon wattage.

I know but i think is a good exercise for everyone want to do something like this and a personal try (I am already thinking of purchasing a shelly P1 to do this accurately)

So how often does the values update on the sensor? is it every 10 seconds or more often?

5

Sensor updates every 1 second

I have set the timeout to 60 seconds in the join node. Change it to what you want, but I needed 60 seconds for my sensor I was testing on.
