This is the issue I described here . Amina has investigated the issue and found a cause, but it needs to be solved by Athom in their zigbee code…
I had good communication with the Anina engineers and performed some tests for them.
i created a flow that detects when the issu occurs, and after that it stops the charging and restarts the app.
Did you update to the latest Amina firmware?? (On the charger not homey).
That did improve the behaviour for me. i hardly see the phase switching issue
Check out my flow shared above, I do manage per 1A even in 3phase.
Insights also show the return is within +/-300W (which is around 1A)
PS: the 6A limitation is not Amina, cars will just not allow <6A
Strange do not see that, did not even know it was possible to charge on 2 phases at all.
What happens if you plug in the mercedes at the street? Does it charge at higher A?
See post: “This Mercedes always receives the full 3-phase power at all charging stations I ever connected it to, for a total of 11kW.“ 
I did not ask anything about the minumum level of charging
But see above: Cars normally do not charge below 6A, but the limitation is also on the Amina side. Its logical that cars and chargers both apply the IEC standard minimum. Though the Tesla App even offers the 5A option.
Could you try to set your Amina on 16A (by hand) on 3-phase and then check what the total consumption of the Amina is? Is that 16A x 230V = about 3500 Watt or 3 times 3500 Watt?
If I put the Amina on 16A and single phase off then it consumes 3 x 16A x 230V = about 11Kw.
In my opinion: could not work any other way, because you have to get 11Kw in total on a 3 phase outlet.
If the Amina could be set by 1A devided over 3 phases I should need the option to set it on 48A, because only then 11Kw could be reached: 48A x 230v = about 11Kw. So I think it is not posible to let the Amina e.g. consume 19A. But 18A is possible: 3 x 6A. Also 16A is possible (16A 1-phase). But not 17A (overload on 1-phase and you can’t set 5.66A on 3-phase).
Or am I confused somewhere?
I know, its charging at 11.2kW so definitely 3x16A
Just checked my own flow Iguess you are right, it is not possible.
I never noticed because my solar panels never produce that much power as return energy…
I also have an “easee charger” and I am using exactly the same flow for it. So not sure if there are chargers that will do this
@FKey: In any case, thanks a lot for your help and for checking the Amina. I now have a better understanding of how it works. I think I’ll ask Amina if the maximum amperage can be set to 1 or 2 decimal places. If I could set it to, say, 5.66A, I could achieve a total consumption of 17A (3 x 5.66). I’d also like a flow card or a parameter “reset” that allows the Amina to actually switch between 1-phase and 3-phase. Or an automatic reset if I set the 1-phase parameter. You experienced the Amina freezing after a Homey reset; to me, it’s clear the Amina switches from 3-phase to 1-phase by switching the charging on/off, but doesn’t go back to 3-phase. In that case, a full reset of the Amina app itself is necessary. That could be improved/made more convenient.
The Amina charger is an excellent product in itself and could be improved further. I’ll let you know once I’ve contacted Amina.
The contacts of both amina and the app maker (dresno) are at the top of this thread
That card is already available, you can check my flow on how to use it.
Phase switching in the flow is working fine. But you do need to include a stop&start charging. That is a techincal thing in the hardware, so cannot be changed.youcan read the response of amina in this post
I don’t see a ‘reset’ parameter in your flow. There is a yes/no switch for the 1-phase setting and a way to turn charging on and off. That only works for me when switching from 3-phase to 1-phase, but not the other way around. Then an additional reset in the Amina app is also required. I’ve now asked Amina for a single reset option that resets everything needed to actually switch back and forth between 1-phase and 3-phase. The current setup is cumbersome and unreliable. There should be a better way. I hope Amina can implement that. I’m patiently awaiting their response.
Did you install the latest firmware on your amina??
This one fixes an issue with phase switching!
the phase switching works flowless for me. The issue that the switching on the amina does not happen while homey gets the response that it is done also hardly ever happens to me.
The flow that catches this is indeed not in the flow I shared. I have it in a seperate “alarms” flow
When it happens I stop the charging, restart the amina app, and restart the charging.
I have a request in the sysinternal to have the ability to recognize when a single app has restarted. That would improve this process.
Amina cannot detect that this issue occurs as it is an communication issue in zigbee (they explained to me)
Just checked my mails with amina, the way to make this stable was by adding a delay before starting the loading:
