I doubt you'll find any that are truly 1800 watts, outside of a commercial device, due to NEC continuous duty de-rate on branch circuits. I think it's 85%, so a 15 amp is de-rated to 13 for continuous duty ... which means manufacturers are limited to 1500 watts.
Not a smart oven but has a wireless temperature probe? Those sound like mutually exclusive options.
Big enough to hold a hen? Something like the NuWave convection cooker comes to mind. (1500 watts)
