@Goose66 - I just upgraded to the EISY over the weekend and converted my Polyglots to PG3x. The MyQ is only showing 1 node versus 3. I am using the Polyglot on m Polisy using PG3 with no problems. I tried reinstalling, restarting, powering down the EISY to try to resolve. Firmware is 5.5.9 and all the other Polyglots are functional using PG3x - 3.1.23.
