After adding the serialid (which is my Netro Spark serial number that I see on the Netro app, settings, under controller), I click save and than restart. Message pops up that says SerialID <serial#> generated ERROR, check device is Online and that tokens are available.

I checked that I typed the serial correctly (cleared and retyped), also removed Netro plugin, rebooted Polyglot, and reinstalled plugin.

I checked that the Netro controller is online.

I have sufficient tokens as there has been no excessive polling to use them. I also waited 2 days after it was configured, still see the error message.

What has others done to configure this plugin?

Here is the response from Netro (dated July 12, 2026)

We would like to explain that we released the new Public API V2.0 in October 2025. To better protect users’ sensitive information, such as device serial numbers, only users who were already using API V1.0 before the transition are allowed to continue using V1.0. All other users are required to use API V2.0.

After checking the issue you described, it appears that the current plugin (version 0.1.18) is still using the older API V1.0, which is why the connection is not working properly. The plugin will need to be updated to support API V2.0 for new users.

We also noticed that the current plugin may have some compatibility issues with the new API.
