[APP][Pro] Alfen - Optimal Charging, Smarter Homes: Powering Efficiency for You and the Grid

Hi, is it possible to add to the status indicator:

the specific powering setting:

so that in the top right I can immediately see if the unit is in the right status? Always want to maximize the car charging from the solar power

Don’t think that is possible. The status indicators are all automatically generated. Don’t think I can make something to show it there.

Oke clear, then I might need to make a separate advanced device icon.

I have 2 Alfen Chargers for 2 cars. I have them both in Homey. I can adjust the “Stroomsterkte Limiet” for one of the chargers, but not for the other one. Does anyone have any idea why that is? The funny thing is that i can adjust the load speed in kW in the Eve connect app for the charger that seems to be not responding in Homey. Homey can read out all up to data of both chargers. I hope the someone knows what te problem could be here.

One charger with two sockets? Or two separate chargers? And if two separate chargers, both same model?

2 separate chargers. One is an Eve Single Pro line (thit is the one that I can adjust) and one is an Eve single S line (this one I can read out with Homey, but I cant adjust it with Homey.

Ok, I think the Eve Single S line has different API properties then the Eve Single Pro Line. But as there is no public API documentation available this is only a guess, and nothing I can do atm :slight_smile:

Ok thanks. I still hope there is some way to control it with Homey in the future. Since the Eve connect app can control it remotely, it should be possible. Fingers crossed…

Is it somehow possible to add the charger in the energy dash?


Isn’t that supposed to be the ev value?

no it is not. that is the total usage of the energy supplier. it is the sum of own consumption - solar power from solar panels.

Okay, that doesn’t seem very logical to me, as I would expect the sum to be shown in “stroomnet” (under the animation). Also, you would expect “EV” to stand for “Electric Vehicle,” especially since the graph includes an illustration of an EV with an animation showing power flowing to and from it (V2X).

Is there a known issue with resetting due to the connection with Homey? My Eve single pro (firmware 7.1.3-4342) was resetting multiple times a day, even while charging. This caused the charging to stop and not resuming. I noticed a lot of startups and i looked for a cause.

In the logs of the Alfen i get a watchdog reset, a few lines later an “out of memory” failure.

Yesterday i removed the Alfen app from Homey and no resets ever since.

On other fora i found that this can be caused bij to much API? readings? The problem also accurs with Home Assistant.

I just read-out the Alfen en did not use it it any flows.

Hmmm, maybe explains the issue I was seeing as wel that charing completely stops. What I am also seeing is that in green mode it stops seeing how much power is being supplied and stops charging, because it thinks pv is a 0watt… It also does not resume by itself.

Not sure if it is Alfen, the wifi or the app though.

I understand what you mean! But look at this picture:

And look at this picture from yesterday:

Yes, I know this is how it is shown currently, but hope that is a bug.

I have downloaded the app to my Homey. What username do I have to use to login, I tried it with Owner, but taht did not work.

During the last week, my Homey keeps crashing. The only thing i can find is this:


Where the CPU usage rises, Homey crashes.
Is it possible that the Alfen app causes Homey to crash? I now have shut down the Alfen app to see iff Homey wil crash again or not.

Does the crash happen once a day around the time you would expect a backup of homey will be made (after midnight)? That is a bug. But perhaps this is a different issue. If the crash still happens disable auto backup to see if that solves it

It started a week ago. I thought Homey died. But later it al starts working again. But Homey crashed every few minutes. Later it worked for 2 days and yesterday completely dead again. After some crashes it worked again but today at 2pm Homey crashed again. The only thing in Homey that seems strange and that i can find is the cpu usage off the Alfen app. First it goes to zero and then 25. At the same moment off the crash.
