I had my HERMS built (moreless) ready for a while, so @Elco helped me to go and do a test brew.
I used a developement version of the firmware, with a somewhat āadaptedā (read: hacked) web frontend so that I could drive my electric valves, pumps and stuff, as well as use the PID to control the mash temperatures.
ALright, I am now sitting at the computer and looking at the system, with the wort boiling and a mess around it. It works, sort of. I have to sort out which PID values are good, as I had some swinging and the temperature was not kept stable - even if, for this test sake, it was +/-1Ā°C - and I had quite some glitches in my built (one pump was not strong enough, but luckily I had a replacement here, and the inlet of the Mash tun needs improvement). So, why am I writing this here? As far as I can see it, it wonāt be long that a release with real Mash (and valve control) ability will come
There seem to be some bugs around, but hey, I am really happy!
Just hang there a bit more. I did the mash with the current web interface, and had to adjust the PID settings from there. It is working with the dev versions I had, plus - for convenience - I also added a web page for controlling valves (if you have any). This was quite amusing, as I programmed it so that you can set all your valves at once to a defined state (like, āMashingā or ācleaningā or whatever. Having 12 valves move at once is cool
This looks lovely. I am new on the scene, slowly putting chunks on my herms system, and the electric control panel style system just didnāt seem modern enough.
