From what I’ve read so far, it’s already included in the Alfen software. When you choose 100% green it will communicate with the P1 meter and charges the car purely on the surplus. The only uncertainty is how to make sure you’re charging single phase. Otherwise you’l be charging with 3x6a minimum. More than most PV home installations can provide. The handshake protocol between car and charger should manage that. So when charger is in green mode before you plug in, it should start with 1 phase charging. The test I could do so far, it will allow charging below the 6A threshold as well
About the spikes in paused charges; when a car is plugged in, there I a small bit of communication between car and charger. But that communication is also keeping the various systems in the car active. Draining the 12v battery. The 12 v battery is only charged, when the main battery is charging. My hunch is that it’s on purpose that the car starts charging, in order to trigger the 12v batteries charging.
I don’t know exactly what you mean? What is different and/or working in the old version that isn’t in the new one?
And what kind of charger do you have (single or dual socket?).
I have no issues with my single one with the new app (although the start/stop charging buttons seems to crash my charger, and then I have to reboot - so I think that is quite drastic, also can’t find an official start / stop mechanism in the app).
But wondering what issues you encountered and if they are reproducible so that I might be able to mitigate them.
We had some issues with the 12v battery of the car (VW). The ongoing communication between car and charger was most probably causing this. So I was delighted you’ve founded a way to stop the charger. Not so delighted that it produced an 206 error. And then it got from bad to worse. Checking the settings with the MyEve app, getting locked out (due to two devices trying to connect, my bad). But I could undo all of that. This morning I was able to take control again. Except I couldn’t get the insights. Couldn’t check when it has started charging and so on. Then finally I went back to the “old” version, and I immediately had the insights back. I did do several restart of the app and homey (and charger) trying to test everything. Al in all it toke me some hours trying and testing. Don’t get me wrong, I like this kind of stuff. Don’t mind to puzzle a bit. I probably will install the new app in a couple of weeks, giving it another try. For now I don’t send the amps back to one, but set the charger in green mode to stop charging
Note, not sure it was the charger causing the 12v issue, because the car is now in shop for a high voltage malfunction.
Going back to green doesn’t do the job proper, because the sun isn’t always down ;-). I need to set the charger to accepted phase mapping. Is there a quick and easy way to stop the communication between homey and charger, so I can use the Eve app for this setting?
Btw, I did install the test version back on the homey, and the insights are back again.
Edit, phase mapping was already turned on, but somehow the charger will use all three Phases. (L1, L2 and L3, whenever I have a surplus on L1 due to my solar panels.
@Andre_van_der_Steen in my experience I can use both Homey and the Eve app along side, both not at the same time. Meaning, use Homey to set one thing. Go out of Homey and into Eve app, and change another.
Basically that yes, but if I recall correctly I do no even have to close the Homey App (but yes that is the best way), as long as you are not in the device or sending commands in Homey to Alfen). iOS works about the same.
I’ve set loading to 100% green in Homey. And changed it back to normal in the Eve app for example.
