And relative to the Updates available (Firmware and Config) - this is another common FAQ since not all WiFIRE controllers are upgrading "as expected" to the latest releases:
Firmware for all Traeger Grills is currently 2.01.0 - that is likely to change in the month of May as another update is forthcoming ... The ability to support 500 degrees is tied to the Config data file version for each Grill, and that value is Grill Model specific - see the following:
https://www.traegergrills.com/status
04.016 is the current Config data version for the PRO 575
03.010 is the current Config data version for the PRO 780
08.005 is the current Config data version for the Timberline 850
07.006 is the current Config data version for the Timberline 1300
06.009 is the current Config data version for the Ironwood 650
05.009 is the current Config data version for the Ironwood 885
10.005 is the current Config data version for the Silverton 620
09.005 is the current Config data version for the Silverton 810
11.005 is the current Config data version for the Century 885
The pending May Update SHOULD address the KNOWN ISSUE for those Grill owners who are unable to get WiFIRE to update to the latest Firmware / Config versions - so you may need to be patient and wait for that release to go live ... and at present, updates can only be PUSHed down from the Traeger Cloud, so you cannot invoke it manually ... at some point, the Traeger App will support PULL updates, so you can control if/when the update(s) are installed ...
