Video Doorbell push too hot

We lost our Ring Video Doorbell last Saturday when we lost internet for a while. After rebooting the router everything came back except the Bell. We cannot seem to get it to re-connect however the bell push is very hot, we've just measured the temperature at 118F. This is a bit of a worrying. The transformer is at a normal temp, just the bell push. It's in a covered porch, facing west and currently not in direct sunlight. Is this a fault? It's only 7 months old.
