An off the wall thought. For Decent owners, why not just use a regular but empty basket in a PTF, to flow water onto a Hario DripAssist sitting on a V60 cone and filter. Or just direct from the dispersion screen to the DripAssist (no PTF basket). Then set up a profile that will pour water (including initial pre-infusion) at the timing, pace and flow rate desired. With the scale linked to the Decent, of course. The “shot” could set up to stop at a set weight, or a volume (in which case no need to link the scale).
Great for the first morning coffee! Turn on Decent, grind coffee, setup the v60, select the v60 profile and hit pour. Then make toast while your v60 coffee is pouring. 🥱☕
The additional benefit would be a consistently well made v60.
