Both times I have reached out to their support they have been really great. As mentioned above they can access the unit from their end if given permission, but skipping all that and getting a new brain is even better I would say.
If you are worried about any automated systems currently running in the mean time you could call and confirm with them, but I believe in the event the unit is disconnected it keeps running all the same settings regardless.
"If you have used the resources here and here, do not want to wait for us to contact you, and still feel you need to contact phone support, then please contact us at 408-779-4090 then press #1, M-F, 9 am – 5 pm Pacific Standard Time."
I would definitely call if you are concerned or still waiting. Their support has been excellent to me so far
