Hot off the press.

Usual warning and guides…
Make sure you back up everything before you upgrade.
If you are using Ignition back up the Gateway settings and unactivate your license.

This is mostly an ‘all about RIO’ release.
Some good bug fixes (VPN), but it mostly adds RIO support to groov View and the PAC Control Engine.

Read all about it in the readme;


Cool! Continuous working VPN is what I need…

Is it just me or was 2.0.0 rolled back? I’m only seeing 1.5.0 as an option on MyOpto.

Yes, it has been rolled back for the moment.
There is an issue with Node-RED in the 2.0 firmware that required the roll-back.
We are working on it and should have an update in the next few hours.


Here is the KB on the issue.

Update on the update.
We hope to have 2.0.1 released around Tuesday (May 19) which will address this issue.

Thanks for getting this out. I have to say, support and the developers were stellar on this one. They were able to get me a patched build for the serial communications issues very quickly. Great job!


well done Opto22 team!
