The phone connects to the wifi network REMOTExxxx fine with the password, no internet of course. But it connects.
Basically the problem is that when you enter the wifi password in the app, the app doesn't switch networks to the REMOTExxx ssid. If I manually switch it, it still doesn't work.
I have a Galaxy 9 and recall having some issues with the phone jumping around between Wifi networks. I have the phone set up to forget the car's wifi network but retained the automatic connection to my home network. Just as you, I don't leave at set times everyday. So here's my procedure:
- 10 or 20 minutes before I leave (depending on the outside temperature) I hobble over to the kitchen window (closest to the car/driveway), manually switch networks to the car's "REMOTExx"
- after connecting to REMOTExx I start the PHEV app and turn on the heater (I use defrost rather than just heat - nice that it also turns on the rear and side mirror defrosters)
- after seeing that the command is successfully sent to the car I kill the app and the manually reconnect to my home Wifi.
As an aside, I increased the heater time-out from 10 to 20 minutes. When it gets colder, 10 minutes doesn't cut it.
My more convenient solution is to send a text message (sms) to a slave phone that I have in the car. That way I don't have to be within 20 meters of the car or fiddle with Wifi settings.
You can read my ramblings on the thread "Remote access via sms and Tasker..." here http://www.myoutlanderphev.com/forum/viewtopic.php?f=11&t=4122
In that thread Zuikkis posted an innovative solution to problems with the slave phone's battery dying.
Hope this helps.
