I am a brand new Home Assistant user. I have Home Assistant setup, and access from my local network (browser and companion app) are working fine.
What I can’t figure out is remote access through the companion app.
I have created an account on Nabu Casa, and I have enabled remote control in the Home Assistant Cloud settings.
When I turn off Wi-fi on my phone, I can successfully access my Home Assistant through the browser, using the “Connect” link from Nabu Casa. But the companion app doesn’t find it. I get a blank screen (nothing but the settings button in the lower-right corner). After about a minute, I get a red popup with the message “The request timed out. NSURLErrorDomain -1001.”
There must be a configuration step I have missed somewhere along the way. (Did I mention I’m a newbie?) Do I need to give the companion app my Nabu Casa credentials? How?
