Sort of. I have a Green Egg with a Fireboard2 Pro. Using the driver from snell talked about here:
Just messaged him and he sent me a link to his Github. Using his driver, some hub variables, and some rules in RM, I get house(voice) and app notifications when the grill is at temp, when it's time to flip, when the cook is done, and if the grill temp gets too high or too low. I use a dashboard for changing the settings and turning the monitoring on/off.
