Is that an arbitrary software limit that could be changed?
This limit is set in the Firmware of the Controller. You cannot change this.
Only Aquacomputer can change this limit, they have done it in the past.
(In theory, you can try and modify the Firmware yourself, if you have the required skills and hardware to read the Firmware from the controller,
find the encryption keys, do some reverse engineering, find bugs in the firmware that allow you to modify it, and so on. This is very hard and probably impossible to do.)
