Creating a local api user on plugin battery

[msioen]

I'm unable currently to create a local user on my plugin battery so I'm wondering if I'm missing a step somewhere.

As reference: I have both a P1 meter and battery in my network. On my P1 meter I do have a local api user and I use the API. Both P1 meter and battery correctly show up in the application. If I fetch the users from my p1 meter I can see my own local user and a cloud/battery user.

Every time I try to create a new local user on my battery however I get a timeout. If I try other api calls with incorrect authorization I do get a response so it really feels that something is going wrong with the user creation specifically.
=> do I have to press some buttons at some time?
=> is there a setting in the application which has to be turned on (there is local api text but no toggle button so I'm assuming this is on by default)

Reference screenshot shows that

• I can find both devices on the network
• creating a user times out (variants with other names and specifying json header result in the same)
• trying to get a measurement with another user (from my p1 meter) correctly returns unauthorized which seems to indicate the local server is up and running

Any help/suggestions are welcome to get this setup correctly.
