Thank you for your quick response. Unfortunately I was not able to re-commission through the HAN dashboard or by calling PGE. I was escalated to a Supervisor who told me that once registered with a unique MAC address they do not allow that MAC to ever be provisioned again. She said the only option was to contact the manufacturer and ask them about changing the MAC address of the device and then provision that new MAC through the HAN Dashboard. I told her this did not make any sense since being able to change a MAC defeats the whole purpose of MACs in the first place but she insisted that is the only option as they will not delete from their system the MAC of a device that has already been provisioned and the system does not allow a device to be provisioned more than once, unless the MAC changes.
