Here u go the short version.
I use the P1 meter of the house to see what i have to put in the car (it measures every 10 sec).
-
First i calculate the watts to amps:
-
Then i calculate how many Amps i have to put in the car:
So the Amps from charger minus the Amps of the house = the Amps i have to set the charger to.
- Now i know what to set the charger onâŚ
I could put the variable straight in the set âdynamic charger currentâ but i put a extra check in it to make sure that the value is correct.
I donât stop the charging of the car (donât want that) but offcourse this is easy to add if u want to.
Iâm going to make a long post on our website and youtube channel.
This is how i looks like in real life:
P1:
Charger:
Sometimes to charger jumps a bit when there is no sun but this is not a real problem. I tried to fix this using the âaverage or trends cardâ but was not happy with the results.
Thanks, inspiringâŚ
I am using the dynamic circuit current, not the dynamic charging currentâŚ
(Not sure if it makes a big difference just having one charger)
Are you using 1phase charging? 3phase charging? Or both?
I am using 1phase charging for the moments of low sunshine (1.38kWh, 6A) going up to 3.58kWh, 16A) then switching to 3phase (4.14kWh, 18A) going up to 11kWh, 48A
My approach (just started setting up) is a bit different.
I am using the insight trends app to calculate the avarage of the P1 signal over 15 min.
Recalculating that (just like you) to a current.
Based on the trend (also from insight trends) of the expectedsun script (changed to 1hr iso 3hr)
I decide if I actually want to update the current
What is your experience with using the dynamic charger current?
I am using the âdynamic circuit currentâ what notice (just 2 days of playing around) is that is seems to only adjust the current for even value.
The odd values (changing from 6A to 7A do show in the easee app as an updated current limit.
But the current itself does not changeâŚ
Only when increasing to 8 I see a actual charging current change
Donât think it makes any differences if u use the circuit or current. I have 1 fase and 1 charger.
I tried with the insight and trends but the charger was always behind the P1 and using to much power or not enough to burn the solar away
Dynamic charger current is working fine here. I didnât notice any weird behavior. But let me check when the car needs charging.
Just removing your first card (is smaller than 6) would already stop the charging if not enough solarpower is availableâŚ
So not even âeasy to addâ⌠, easy to remove
Difference might be the 3phase charging, not sure if the dynamic charger current will automatically switch between 1 and 3 phases.
Dynamic circuit current will allow you to switch.
I will test it it when my car needs charging
To make the flow more accurate,
You are using #Current allocated, that is the maximum current that you assigned yourself
The actual current used can be different. You can see it in the easee app. Actual current is 6.3A, allocated current is 7A
To be more accurate you can use the actual current provided by easee (to be 3phase compatible, take the sum of all phases
i was wondering why the charger was not responding.
There is a problem with the API:
Identified - We have identified an issue with our backend services and currently 3rd party home automation systems may be affected when trying call the /api/chargers/{charger_id}/settings endpoint
Hi!
Is it possible to make us use variables when creating schedules?
Maybe possible to create the schedule with homeyscript? Iâm trying to create some dynamic window for charging dynamically - maybe someone already has something working?
Looks like I can fix this with Action Scheduler App for Homey | Homey for now
When activating a charging session, the actual start price is normally used as the price for the entire charging session time. Mostly price goes up every hour after the start. I created a flow that calculates the highest average within known dynamic prices, follows price increase (8H) and decrease (price now) to the calculated average for a weighted starting price every hour.
It still follows price changes but is a little more fair if you want to reimburse actual charging.
You can change the average pricing calculation by changing the calculation formula as you like.
Enjoy
