Try to disable auto backup. Perhaps due to your issues it was not able to finalize a backup and keeps trying causing the crashes. Maybe it is not related but worth a try I would think.

Just had a crash whitout Alfen running. So never mind, Alfen isnât the problem.
Turned off the auto backup. will see
Hi, question, what is the polling frequency of the app? I often see that the power useage is very much trailing what is actually being used. Is it possible to change that, or the API does not allow it?
Currently it is every 30 seconds. With the limitations of the Alfen API I wouldnât advice to have a higher interval.

Since this morning at around 5.45 am my Alfen Single Pro suddenly started to charge (6A) I thought that could be caused by a fault in my programming (flows) or because of an software update of my car (it was updated this night). But I now see that the Alfen doesnât respond to any commands from Homey. I can however see the Alfen in Homey and I see all readings correctly.
Does anyone has any idea what can cause this and how I can fix it?
As you can see in the picture below, the âStroomsterkte limietâ is not beeing updated for 16 hours nowâŚ
I just tried to cut the power totally to the Alfen, to force it to reboot, but that didnât work. Looks a bit like there is a bug in the API or something?
Update!: I had contact with Eneco. Apparently the Alfen was in a âniet goed afgezekerdâ mode. A hard reset from Eneco solved it. They told me I could do a hard reset myself by cutting the power to the Alfen for more then 15 minutes.
I think that I might have caused this by letting Homey adjust the max Ampere every 2 minutes. Ill adjust my flows that it will only adjust it every 15 minutes or so.
Why do you change the max power so often?
Changing the max A every 2 minutes is not an issue. I use Homey for loadbalancing my Alfen Eve Single Pro. A Homey flow controls the max A to prevent overloading the main power connection/main circuit of my home.
I do this this way because I had some issues with the loadbalancing of the Alfen in the beginning (responded too slow) and I use EVCC now to control the Alfen to charge in different modes (max or solar only) and to charge only with energy prices below a specific threshold. If you use EVCC you cannot use the loadbalancing of the Alfen itself. But homey can control EVCc and with that the Alfen.
My homey flow adjusts the max A of the Alfen every 10 seconds, but only if the change in A is significant, only if the power usage is close to my home maximum and only if a car is actually charging.

Hi,
Iâm currently using the Homey Pro 2023 and Alfen app to control my Alfen Eve Single Pro-Line.
Iâm trying to limit the AC current on the charger using Homey but for now, everything else as 20A (limit of the chargepoint, or higher) is accepted. When I go lower then this, the chargepoint stops charging the car (Tesla Model Y). When the current is raised to >=20A again the charger start charging again.
When I limit the car to 5A charging, there is no issue at all.
Anyone here having a clue what I might do wrong?
Something strange the last couple of days, and not sure it has anything to do with the app, but maybe someone has an idea.
I swith throughout the day and the weekend between default, green and comfort, while the connector remains in the car. Last days I have noticed that charging does not resume automatically. I either need to press the button to remove⌠the connector from the car (then charging resumes), or need to hold the rfid to the alfen charger again.
I seems it loses some sort of connected. anybody know what might be up?
Also sent a diagnostics to be sure

Noticed the same here when switching between charge types. I think it is in the charger itself (couldnât extract anything useful from my debug log and your report).
What always happens is that charging goes back to 0. The after half a minute or so it resumes charging. Sometimes my car disconnects when this happens because it is of the opinion that charging has stopped. In those cases I have to do the same as you and reconnect the cable.
would this then also happen when on green, and the clouds come, the total power drops blow the 1kWh will then the connection lose as well?
I do have the feeling this did not happen in the beginning (or am I mistaken). Something changed on Alfen side or on the app?

It just out of the blue stopped charging. No idea why, sun was shining fully
Sorry, canât help. The app doesnât send signals to your charger (unless you build flows yourself that are doing it). The Alfen API is fully closed and not supposed to be interacted with on a high interval and doesnât send any error or debug logging when it stops charging.
The app didnât change for the past month or so. I think it might have to do with your load balancing at home, or maybe you are overloading it with commands?
Overloading could be, so will change the flows and see if that improves
Great app.. thank you!
I was wondering if it is possible to add a setting for phase shifting. Not sure if this is in the API, as it might be an installer setting.
Phase shifting is the chargerâs ability to reduce the number of phases (wires with electricity) when less load is asked from the charger. In this way it would be possible to only send one phase of energy to the car giving it a 230V*6A= 1380 Watt load. For my charger 6 amps seems to be the minimum. So 1380 Watts would be the minimum in my case if phase shifting was enabled.
My use case is simple. I like to âtrickle loadâ my car from the solar panels. However in optimum conditions my panels produce 2800 Watts. The phase shifting was not enabled by my service provider, so the charger uses always at least 2 phases with a minimum of 2760 Watts. So charging my car means that it always takes from the grid to get to that 2.7kW minimum requirement. The car will be full earlier and that means that I have to give the solar back to the grid.
In 2027 the Netherlands will no longer allow ânettingâ the usage. So I would be using power from the grid to get to the minimum requirement and give back solar power when the car was fully charged. It would be nice if I could extend the trickle load as long as possible.
Not sure if the setting is in the API. But I would love to have it implemented if it was there.
In the promotional screenshot of Homey energy they have an Electric Vehicle button. Does anyone have this working? And if so how? 
Not working here. I alsof want to know how to do this.
Just turn on phaseshifting in the my eve app and thats it
