Just made a copy/paste of what you have

Hej Anders!
I like your code very much -- especially the delayed and more persistant switch between one- and three-phased charging. I am running something similar, but will most likely adopt some of your code. One little difference is e.g. that I am using a lowpass filter instead of averaging the power production and power export, which performs slightly better in view of spikes (e.g. when switching larger consumers on or off in your home).

• But I wanted to ask whether you have a battery connected to your installation and how the code performs with that. I am not satisfied yet with the performance of my (similar) code.
• Further, Easee write that their Equalizer only changes the current setting every 10 minutes to prevent wear on the electronics. And I see that another product (the Wattpilot from Fronius, rf. https://manuals.fronius.com/html/4204260400/en.html#0_m_0000024035) only changes the power every 5 minutes with the same argument. However, your script pushes a new value every 20 seconds. What's your view on this? (No offense, I have honestly no idea myself).
  I look forward to your reply!! And -- by the way -- if you have any updates to your code, I would be interested as well =) Cheers,
  Holger.

Thankyou for your interest.

Yes lowpass filtering might be better than averaging to remove spikes - but the changes i have are real and so not really spikes but fast changing available current. I'm also using the 10 minutes minimum for switching i,e the low spike get me back to 1 phase . In the end the different filtering depends on whether you would balance between selling to much or buying to much. My main issue is not spikes in consumption but spikes in production whenever a cloud passes. With the above automation the excess buying/selling is about evened out (but i'm also runding up the current send to the car to move the average a bit)

When you change the charge current in the easee app it will be stored in the flash memory of the charger. But when you change it with the set_circuit_dynamic_limitlike i do every 20s iin "PV to EV Dynamic" it is not stored so does not cause any wear.

On the other hand the relay switches that is making the easee home a smart charger does wear when used. So i have limited the change between 1 and 3 phases to every 10minutes just like easee does themselves (in "PV to EV Phases"). It also takes my car "some" time to change. Can't remember the "hole" in reported current but HA only updates every 10s. But it is easy to see that first charging is stopped, then the relais switched arround and charging started again

In Denmark you are not allowed to have single phase consumer of more than 16A - otherwise it would make more sense to charge on one phase up to 32A (my skoda Enyaq support that)

In may and june almost all my ev charging was straight from the sun and including july between 45-50% of soloar production was used directly

for a noob can you highlight what fields i should change to my own values?
and my energy meter only has one output for excess power can that work with this?

what value is expected here: input_select.ev_test_charge ?

what type of sensor is this: sensor.eheexpyg_status?

That is the helper i use to shift between charging according to the easee own schedule or 1 / 3 phase solar charging.

Se comment above from May 1

ok thanks but what with this: sensor.eheexpyg_status ?

@Bjarke88 to create a helper variable go to settings, Helpers and create helper.

The EV Charge mode is a drowdown where you (or an automation) can select one of the possibilities.

The sensor.eheexpyg_status is the status of my primary charger that i use for solar charging . Just replace the seriel number parts with yours.. If you go to developer tools, states and search for "config_ledStripBrightness" under attributes you will probably only have one entity that matches

Thanks

can you give a hint to how you create this part:

Settings, Devices and services, Helpers

and create helper

The type is a dropdown with the 3 options

service: easee.set_circuit_dynamic_limit

charger_id: CHARGERID

%} {%if current > 16.0 %}{% set current = 16.0 %} {% endif %} {{ current
}}
currentP2: "0"
currentP3: "0"
time_to_live: "1"

what sensor is you expecting to be here: sensor.watts_live_11d1042220001670_voltage_l1

what sensor is this: sensor.pv_to_ev_power

See above from line 150. That is just a helper to calculate available power.
It looks at currente charge rate and the export and a bit of rounding.
If you are charging with 6kW and exporting 4kW you have 10kW available for charging.

The reason i've done it that way is that it was easy to add statistics sensors that looks at 2 and 10 min averages as welle as minimum.

I use those to decide when its time to change between 1 and 3 phase charging. In the above i will first change to 3 fase when the minum surplus has been over 3680W for 10 minutes. The other way it will first drop down to 1 phase again when the average has been below 3680W for 10minutes.

So on a day with many clous the min drop often and it will stay on one phase charging..

On a good sunny day it will stay on 3 phase even troug i use a lot of power for a short while for i.e a cup of coffe (if its get below 6A it will pause for a while)
