Will this flow work regards to automatically change charge speeds?

Questions & Help
21

The last flow didnt work either. I tried to turn on stove etc. and netto flow was 8000W. But i got an message on my phone after 5 minutes that said my “charger was set to 30A”.

So something happens, but its not right. I just do not know what going wrong here…

When i run test flow in advanced flow all works fine. The right charge current is being choosed etc. But in reality nothing work as aspected.

It must be the timers? Is my timers right?

I have changed my timers from countdown to Chronograph now, just for testing.

But i can’t test the flow before the morrow.

By the way regarding the Chronograph app:

In the cards

  • You only need to fill in either of the parameters, preferably the first parameter (Pick field). I don’t think providing both will work.
  • When using the Pick field, you need to make sure you select the name of the timer from the list. If the timer does not already exist, then - when you start typing in the field - you’ll see the same item appearing in the list below the field with a ‘new’ label .You need to select that from the list.
  • Specifically the card included in the above screenshot will not work (as expected) as both timer names are different.

Also you need to save the flow after creating the timer, to find it in the list of created timers on the next card.

I have tested the flow now and i think i have found the problem. I looked in timer status and look for timers that run etc. This is all over the place. Specially 20A, 30A and “cutoff" timer was randomly startet when i used 7.500 netto power.

Så the problem lies in the timer setup, but i don’t know what the excatly problem is…..

Some ideas?

Changing the charging Amps has no effect on the netto_load if the Main power usage is updated after or at the exact time the Charger usage is updated.
To make sure the netto_load is calculated with the correct Charger usage I would add a delay. If the charger is reporting every 15 seconds the delay should be at least 15 seconds.

27

Thanks. I guess you have a point here.

can you tell me where i should put in delay in the flow please?

PS! “The power changed” card in your screenshot is the main power, not the car charger.

28

This is not a good advice. If you put a 15 seconds delay between the ‘Power is changed’ and netto_load calculation there’s a chance the trigger is triggered again during the delay.

What if you start a timer ‘charging Amps changed’ of 30 seconds after each ‘set charging to x amps’-card and after the ‘stop charging’-card?
Then you can put a timer ‘charging Amps changed’ is not running condition between the ‘power has changed’ and the netto_load calculation.

29

Besides the possible miscalculation of the ‘netto_load’-variable I think you are using the wrong start timer-cards:

Let’s say the ‘netto_load’ goes up and down between 7400 and 7500 and the variable is recalculated every 15 seconds. So the flow ends all the time at the ‘start or replace timer 16A’. So every 15 seconds the timer restarts with a duration of 1 minute. So the timer never ends. So the charging amps is never changed to 16A.
Try using the ‘start or resume timer’-card. This way the timer will ends unless it’s stopped.

Thanks. :slight_smile:

Can you be more spesific regards to witch and where to place the timer you sugested?

See the blue lines.

Hi,

I’ve had the same question to solve with one difference we have two cars to charge. So i’ve got several successive flows. One to determinatie wich car goes first, one to set solar charge or net charge (depending on surplus during the day), one to caculate the max charge and one to set te Charging rate.

I understand where you want med to place timers, but i do not understand the logic behind. Yet. I just want to know and understand the flow also and not just copy paste others idea.

So if you can explain why you will place timers between the blue line and the target i be happy :slight_smile:

Thanks for all help btw. I really apreciate that :slight_smile:

34

I have desided to delete the flow and have made a flow that does not use max/min points and used clock instead, sothis thread can be closed.

Thanks to all that have tried to help btw :slight_smile:

35

An you share your new solution?

(Others might learn from it..)

I can, but it is a totally different flow based on time and when my wife is home or not.

I can post it later to day :slight_smile:

37

This is my last flow.

I still testing, so i do not know how it will work 100%.

I can tell that the last flow worked perfect! :slight_smile:

The flows with load logics never worked for me. I think one of the issues was that my BMW i4 M50 does not like to be shut off and on and the car interrupt the charge.

I guess i could get it to work somehow but it was too unstable and for my use i think the first flows was a bit overkill.

I have an Easee and just check every 30 seconds to increase/decrease the dynamic circuit current by 1amp if the Han is below/above kW limits. At the end when stops charging I just reset the current to 24A. Wouldn’t that be simpler or is there no function to simply step the current up/down by 1A with your charger?

Yea, i hve that function, but my car is not wery happy for rapid changes and when house load a few times chnges fast my car shuts down the charger for safety reasons. Then i kust plug out/in the charger manually to reset it.
