In the FAQ you mention that the device powers on when the doors are opened. Was this an explicit trigger (e.g. is it hearing a CAN signal), or are you using "doors opening" as substitute for waking the vehicle from sleep? The reason I ask is that external CarPlay devices have a couple of problems/inconveniences related to waking from sleep and I wonder if the EV play will have the same issues.
External devices plugged into the 12V socket power on whenever the vehicle wakes from sleep. This can happen for a variety of reasons at any time, it seems. This causes two problems with CarPlay:
1) if your phone is nearby when this happens, it connects to the CarPlay wifi, so you lose your connection to your normal wifi, music stops, etc.
2) if the phone is not nearby and the CarPlay devices remains powered (e.g. when preheating the cabin before departure) then CarPlay times out and your phone will not connect when you enter the cabin.
The typical work around to this is to add a switch or unplug the CarPlay device when you leave the vehicle. I'm curious to hear how EV Play handles these situations?
Thanks!
EV Play has two subsytems: the input switch and the Android computer. The switch is always on, but draws an infinitesimal amount of power. The Android computer boots when the doors are unlocked, and shuts down shortly after they are locked. I don't believe it boots when the vehicle wakes, but even if it did, it too draws very little power. It would also just shut down when the vehicle goes back to sleep.
If you have EV Play set to automatically establish a wireless AA or CP connection, it will attepnt to do so if you are in range. You could also set it to "manual," in which case you would need to establish the connection via your phone or EV Play.
