Hello, I have a solar installation (SolarEdge) and a car charger (go-eCharger HOMEfix). Both are compatible with Homey. I am about to set up some Flows to charge my vehicles as much as possible when there is enough sunlight. Basically, permission to charge should be given when there is enough sunlig…

Avg should be a tag pointing to the variable that you are using (in your case the variable name is Test Moyenne Avec Formule, you need to re-use that variable inside of the formula).

One question is also that how the used/produced energy is calculated for billing? In Finland for example the energy will be mandatory to be billed with hour base net sum. This means that all measured production and consumption during the hour in all phases is summed and the billing is based on tha…

Thank you very much for the precision! Actually, I’m locking for a formula that calculate every 5 minutes the average of the LAST 5 minutes (or 10 minutes every 10 minutes…), and not the totality of the day. Is this formula effectively working in that way?

[image] Picsou621: Is this formula effectively working in that way? No, the suggested formula is a running moving average, I think. It will always take into account all the previous values, not just the last X values.

I’m not really into this, but just wondering, can’t you set like 12 number variables and use those ?

Thank you very much for your answer! Unfortunately, to monitor the energy produced by solar panels to trigger an electric vehicle recharge, this formula is therefore not suitable.

Thank you very much, this is exactly the kind of application I was looking for! I haven’t figured out how to use it yet, but it’s clear that if I can get the average value over the last X minutes of an electricity production measurement by solar panels, that’s exactly what I need!

Blockquote (congratulations to the developer Homey of this app by the way!) Thanks :wink: I have some flows which combine the data from SolarEdge (amount of excess Solar Power (= export)) + Solcast forecast (my other app, which predicts the amount of Solar for my house) But honestly, is there …

Thank you very much for your suggestion (MODBUS). I am not a IT specialist, so I don’t know if it is possible to link the two devices directly. I know Fronius is setting it up with a rebranded go-eCharger, but personally I have a SolarEdge and a go-e Charger HOMEfix (CM-03 version). Is it possible …

The application [APP] Insight Trends was developed especially for the purpose of calculating trends and averages. This should be able to get the results you need without any trouble.
