I have had one of these for a couple of months and am pleased with it. I can confirm that the controller is NOT detachable, although someone with the necessary electronics knowledge could extend it. As the machine is controlled from the app it is not really a problem.
A few pros and cons.
PROS
It is very well made, much more so that the BZ. Construction is mid way between a BZ and the G40
It is much lighter than a G40 and easier to handle. I can lift it up to the sink for cleaning.
The screens are very good, better than the BZ and, unlike the G40, do not allow malt to escape the malt pipe. The bottom screen fits well and does a good job of protecting the pump.
The proportions are better that the BZ and circulation through the mash is much better.
It has a good sight glass which is well protected by a metal sheath and is easy to clean.
Temperature control seems accurate, but it is necessary to drop the power during mashing to prevent excessive variations.
CONS
The app is a bit buggy and although it works well enough it can be a bit irritating at times. It is nowhere near as good as the GF app but is still a whole lot better that RAPT. I have not used it in Auto mode. The app uses Tuya Smart as its interface. (My EV Charger also uses the Tuya Smart interface but has a much better implementation). I am hoping Brewolution will introduce a firmware update at some time.
Thee tap on the recirculation pipe is at the bottom - it would be much more convenient at the top.
It does not have PID if that it something the user wants (I don't).
All in all it is a very good bit of kit and I am glad I switched from the BZ4.
