Can I set up a second user on the app for my account? Or do I just share my login details?
Second user

jhayman4 this thread was for the same thing, looks like you need to create an engineer account

I also set the app up on my wife's 'phone using my log in, works fine.
wilfleek That's what I've done - although I'd prefer a second login really!
Sorry to resurrect an old thread, but I want to add a second login for my wife, as sharing my login doesn't work well with 2FA enabled.
The linked thread mentions logging in "as company". How do you do that as an end user?
ChrisYork you can't. Company is for a set of installers. Gives access to stuff we shouldn't be able to change like export limits etc.
There's no solution to this natively.
Although if you're willing to put the effort in, you could build your own solution with GivTCP and Home Assistant or PowerShell or Python.
