ISY 994 Portal Connection

Featured Replies

Hey All.

I’ve still got a trusty 994 that’s been bulletproof for years, that suddenly lost connection to the Portal. I can still access it locally, and it’s still communicating with the app and Home Assistant (local network only), but will not reconnect to the Portal.

Did something change? Portal no longer supporting the 994? Figures it happened three days before the price of the eISY goes up, and is completely out of stock...

An often mentioned suggestion for the isy994i with problems is to power it off, take out the SD card, and clean the contacts with an eraser, then put it back in and power it back up.

Although the 994 is no longer supported, we still allow 994 to connect to portal and there are no plans to change this in the near future.

That’s good news. Thanks!

I did end up fixing the problem. It was actually a DNS issue. Took a few days to figure that out. For those who may find this in the future, be aware that DNS conflicts can cause the portal connection to fail.
