Nice catch!

If you edit the Plugin Config and change "station_id": 0, to "station_id": 12345, the error will go away.

Will need to update the plugin to check for a 0 entry which is the case when you install the plugin and directly use local mode.

Great catch, thank you. I'll work on a patch release soon.

[DMBlakeley]

@chasenicholl, I submitted a 4.0.1 pull request to address this issue.

[chasenicholl]

@apexskier thanks for the bug ticket. This has been addressed by @DMBlakeley in a just published patch release v4.0.1

Thank you everyone.

I'm seeing this in a just-installed v4.0.2:

Believe the problem is that you may have created the config.json file manually rather than use the Plugin Config option and the "Name" field is missing or is blank.

If this is not the issue, would be best if you shared your JSON config file. Redact your station number.

[bourquep]

I configured the plugin using the UI right after installing it. Then I manually edited the config.json to add my station_id and the warning went away.

[DMBlakeley]

Thanks for submitting! Manually adding the station_id pointed at the problem. On initial configuration with Local mode, station_id is null which produces the error that you saw. Will push an update to @chasenicholl for review and release.
