Error E:CV.PA.29 on the myAudi App seems to be a vehicle communication time-out error indicating that your smartphone app cannot reach the car’s cellular/data module. It typically happens when the car enters a deep sleep state or cellular connection drops during a remote command (That’s what I found out googling the error message).
At the moment there is no possibility in my app to change the charge mode. Is that something you use often?
I let control my Wallbox when and how it charges my car.
Hi Andy - re. the error reported, very strange indeed as I got the impression that the myAudi app was able to communicate with the car on other information. At the moment, I frequently use the different charge modes but maybe need to look into switching to controlling the way the car is charged to the charger indeed (although the integration of my Alfen charger in Homey is not without issues).
I’ve noticed that you also published a “VW Group Vehicles” app. Will you be maintaining these in parallel or will you move the Audi support into the group app? In the meanwhile would either one have an advantage over the other?
Good question — they’re built on completely different foundations, so they’re not really competing.
myAudi talks to Audi’s connected-car backend, the same one the official app uses. That gives you remote control (start/stop charging, pre-climatisation, ventilation, window heating, charge target, battery care) and on-demand refreshes. Around 39 action cards, 54 triggers.
VW Group Vehicles is built on the EU Data Act portal instead — a regulatory data-export channel that hands out a dataset roughly every 15 minutes. It’s read-only by design: no remote commands are possible through that channel at all. What it gives you instead is brand coverage — Volkswagen, VW Commercial, Škoda, SEAT, Cupra and Bentley, for which nothing else exists on Homey.
So for an Audi specifically, stick with the myAudi app — it does strictly more. The group app only makes sense for Audi if you’d rather not have the app authenticate against your myAudi account, or if you also own a car from one of the other brands and want everything through one app.
