I purchased my grill about the same time as th OP in Australia and the current Ironwood series were not in the country then, that's why I asked him if the controller was the same as in the picture I posted The OP has a gen 1 grill, The firmware for our grills is diffrent to the new models. And they are not having the same issues as the new controllers. I think his issue is his WIFI setup.
If it is a Gen1 Grill ... same issue - they stopped supporting version 2 of the Firmware on the Gen 1 grills back in early-to-mid May and have a brief section on this via the WiFIRE Status Page ...
If you have an AC controller running 02 firmware and are having issues connecting it to WiFIRE®, please call our Customer Service team at 1(800) Traeger and we will get you a replacement controller with the most up to date firmware.
So if a Gen1 version of a grill running version 02 of Firmware, or a D2 WiFIRE Controller running version 1.x of Firmware, you end up in the same place - needing a replacement controller since the Firmware was never updated to a supported version prior to the old version(s) of Firmware being deprecated and unsupported ...
You simply cannot connect via the current App version and Traeger Cloud back-end with Firmware versions that are no longer supported ... to recap ... OBSOLETE = version 1.x on a D2 WiFIRE Controller & version 2 on a Gen1 AC-powered controller ...
With regards to the OP - he has never responded with what version of Firmware is installed on the controller ... Gen1 Controllers do NOT have Config Version files, and as such, have no listing for that value under Menu->Settings->About Grill, so that is one easy way to differentiate from a Gen1 to a D2 WiFIRE Controller ...
EDIT: I agree with you magoo40 that there is a connectivity issue with regards to his Wi-Fi setup that will have to be addressed ... but until a supported controller is installed in his grill, he cannot tackle the setup issues ... if this had been resolved before May, his controller would have updated and things would continue to work, but since it has never been setup, the unsupported firmware is now the primary blocker ...
