Can this device be used on any grainfather, either 110v or 220v?
Andres on Jul 8, 2020
BEST ANSWER: This box is not cross compatible with 110v and 220v. This box is intended for 110v only.

So far, so good
I finally had to replace the original controller when it died on brew # 84. I’ve only used the new one once so far, and I didn’t use the app (I’ve seen quite a few difficulties with it online, so I decided to avoid that variable for now). It does a MUCH better job of controlling the temperature, and makes step mashing a breeze. Being able to set the timer to heat the mash water so it’s ready when I get up in the morning is a great feature.
