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

Stijn, I controlled the Alfen post using load balancing, but it's now experiencing an outage (as I've seen before on the forum). I think it's because it's receiving data from the P1 meter and also from Homey, and it's experiencing stress. What's your load balancing setting on the post? Mine is set to "Meter," for example, but that probably needs to be changed. Can you help?

Do you have already a solution, i have the samen problems

No, i just gave up…. I think it might be a firmware thing (?) Eneco tried to push new firmware to my charger, but it did not install. I dont know what else it can be. If you fix it in the future, please let me know.

Maybe I missed it, but is there also a trigger for scanning a RFID? Or plugging in a cable?

Would like to check howmuch energy my solarpanels putting into the net, so I can set the chargingstation to green or to standard if it is at night. After that I would like to start charging (or not).

Also I’m thinking of a dynamic contract for power. Scanning an RFID could turn on a flow to start charging at the lowest X-hours…

The (best?) trigger I can find now is Loading started. But that will start loading and has to be aborted then? Triggering on RFID (or plugging in a cable) would be nicer I think?!

I use ā€œcable plugged inā€ detection on the car side. on the alfen side you can use the car, ā€œis chargingā€

I use measurement if my panels have started producing, together with a timing wrt dusk and dawn, to set to custom during the day to maximize consumption of the panels produced amount to the car with always the minimal amount, to solve when the sun is being blocked by clouds the system continuously starts switching on and off. using the calendar to check if I need the car is needed the next day to then set to default to charge at maximum during the night and ensure the car is full the next morning. in all other scenarios set to green - which is effectively off during the night.

I also check the battery level to the car so I can set the charging to 80%, except when I need to travel far, and then set the level to 100% full, and turn off the charging (setting to green) to stop the charging, iso setting that in the car every time.

The flow is complex and large, and if helpful I can post here, but be aware it is full of loops :wink:

I’ve got one installed recently and immediately connected it to homey with you app: lovely. Seems to work fine, although errors do pop-up: ā€œ Missing Capability Listener: evcharger_chargingā€ wich are errors wich pop up out from cards such as ā€œStart Chargingā€ and ā€œStop Chargingā€, or ā€œStatus Changedā€. Is this a known issue, or might I be doing something wrong (as said, works fine!).

Also there doens’t seem to be a pause card (only charging status is pause). The charger does support it though in there own app. Is that card missing on purpose, or just overlooked?

ZSE Drive told me it is impossible, as my Alfen (from ZSE Drive) is conected via SIM card and having said that, any LAN or Wifi would breake thier connection and monitoring of my Alfen box. Happy to see that it works for Wifi/LAN. Thank for this information

To add to this; Start or stop don’t work (the give the error I mentioned)
