Garage door opener ota issue

I needed to update the opener to add a encryption key. I compiled and this happened:

ERROR Error binary size: Error: ESP does not have enough space to store OTA file. Please try flashing a minimal firmware (remove everything except ota)

Any Ideas on how to get around this?

Thanks in advance.
