You'll need

Hario Switch (immersion base) Required

The Hario Switch's valved base, used underneath other drippers (Hario V60 NEO, Sibarist UFO) to add stop-and-go immersion. Here it is required as an add-on base, not as the standalone brewer.

Recommended Hario Switch
OREA #8 Switch Regulator Required

A food-safe silicone flow regulator for the open base of OREA O1/O2 (and older open-bottom) brewers. The #8 (orange) is the fastest of the set. It also fits a Hario Switch base, turning a flat-bottom brewer into a stop-and-go immersion setup with a quick drawdown once you release the valve.

Notes

Confirm the regulator sits securely before brewing. Keep the valve open for the percolating pours, then close it for the final fill to 200g using 75°C water. Reopen at 2 min and drain cleanly; shorten the hold if fermentation still dominates.
