During the boil, the probe might read 100c well before the rest of the wort has caught up, if you intend to use the SmartPid controller, depending on setting it might/can/may reduce the power to the element once 100c has been reached, meaning a rolling boil is not achieved.
It may or may not be an issue but worth testing non the less.
martpid has quite sophisticated option to mange temperature probe position either inside the vessel or outside in the recirculating circuit . Depending on this all the pump management logic and temperature reading is affected. In the install & config manual in the appendix there is a table that explains all status and details
About boiling with smartPID you can set you boiling point at a desired temperature (also below 100c) and this is the trigger for the boiling count down timer
When temperature reach the boiling point temperature is not more controlled by PID and you can modulate and throttle the power from 0 -100% with pwm control
