Hi all,
First post here so please be gentle with me 
I’m trying to install HA using apps from HACS in order primarily to control my Zappi and integrate with Smartcar to allow charging based on SOC for my Jaguar I-Pace. Annoyingly the car doesn’t allow you to set a desired SOC so I need to mess about with these external integrations.
I have setup the integration with Smartcar and can see the vehicle stats in the interface, but when I go through the OAuth flow in HA, it gets right to the end, and then borks with an OAuth token error.
I was following these instructions https://www.ipaceforums.co.uk/threads/jaguar-ipace-and-home-assistant-make-a-smart-cat-in-your-home-a-beginners-guide.10712/?utm_source=google&utm_medium=organic which aren’t perfect but get me 99% of the way through the process (I get redirected to the Jaguar site, go through 2FA, get authenticated etc) but it seems the token is rejected by HA.
Does anyone have this working? Are there any better instructions out there I can refer to? Or where might I look in HA for some more verbose logs that explain what it’s unhappy about?
Thanks in advance!
G
