Basically, you need to loop over a condition (in this case yourTempProbe < alarmLow). Each time it loops, it will check the value and if the condition is met, then a counter will increase by 1. I don't know the scripting language yet, but I think crane means something like this. {...

Try to just move the entire RTD board and everything into a different room from the A/C unit, manually switch the A/C and see if the spike happens.

I would try disconnecting the AC power to that switch and see if the spoke is The noise is definitely from the A/C unit as you stated, but there are multiple ways it could be causing issues (some without even being on the same circuit). And reducing the number of components and/or isolating...

I would lot run 120AC and the 24DC power in the same switch. Is there a reason you are using a switch and a contactor on the left? Why not just the switch? Also, what are you trying to achieve with the manual switch for the A/C? Do you want to be able to turn on or off the unit regardless of...

You have the 12V supply to the sub-panel running through the 8ch relay board? If so, then you have a relay, driving a relay, driving a contactor, driving an A/C unit, is this correct? For the rotary switch from the diagram, it looks like you have it just as a manual on/off for the 24V dc power...

Those are 12V coils, so on the relay board, you would run + from your 12V power supply to VCC, and - from you power supply to the GND right next to it. Then you wire the pins from your arduino to the IN1-8 pins and arduino gnd to the gnd next to the IN pins.

So, if I understand correctly, to control your A/C unit, you have DC 24V power directly from your power supply going to the "sub-panel". The 24V is turned on/off with the rotary switch manually. When rotary switch is "on" it closes a relay which allows your sub-panel to see 120V power. Then when...

Im not really sure what we are looking at here. I think you have a breaker, ac contactor, DC relay, physical switch, and a plug. What are these doing? Where is the DC power coming from and how is it wired to your board? Is the plug for an AC unit or a fridge? And is the power supply for the RTD...

Is there a way to graph more than 2 things on a graph?

I saw this and read the user manual. So, if you add a new sensor to your system it renumbers all of the sensors, or it one fails it does the same? In not sure why they did not use the hardware address instead of their index system. Or just tie to index to the hardware address. They should also...

Can anyone provide any answer for my previous question? Does the esp8266 interface correctly implemented for pwm? Does it change the default 0-1023 value range to 0-255? Basically, if I use an esp8266 as an interface, does the pwm work as intended? In other words, is 255 = 100% on the esp8266 or...

What about the range default on 8266? Does BC account for that with the pwm device? I've ran into issues on other projects where typical 0-255 is used and esp was not corrected so it was only able to output 0-25%.

Reading through some of the website info, and had a question about 8266 pwm. It mentions in the wiring maps that the frequency is ~500hz or ~1000hz, and I remembered that the esp8266 uses software pwm and the default is 1000 with range of 0-1023. Are you able to change the frequency and range in...

Does BC support using a 1wire master chip such as ds2482? It's an i2c bridge for 1wire which takes care of all timing related ops. Also, when will web interface be released?

I mean there are many different levels of investment in a hobby. The "bread machines" are still making beer and it is still more involved than popping a frozen dinner in the microwave. It also gives the option for further investment into the hobby as well. And who cares if it is a recipe 3d...

I do not have Brucontrol, but I am very interested. Is there a way to build a "process view" where you can "see" the flow between different kettles? For example, have a layout view of your brewery and when, for example, the step for recirc through a RIMS tube, you see like flow arrows through...

Are you sure the TD5 magnet is a ferrite? A ferrite is a specific class of material, basically iron oxide with another element. As I mentioned above, the tan pump used a neodymium magnet (not a ferrite, but an alloy of NdFeB). I analyzed it in a lab (I'm a materials scientist). Does the magnet...

Ok, after some more investigation.... I opened up the tan pump which I bought this year. Inside the plastic coating was the magnet which has some sort of epoxy (I'm guessing) coating which filled with typical paint fillers (Ti/Al oxide). The magnet seems to be NdFeB, with what looked like some...

I feel this is probably the best place to post this..... it should not matter if the ferrite is exposed to the liquid or not. Sr or Ba ferrites (aka cheap motor ferrites) are not toxic and they don't corrode very easily (they are already an oxide). If they do have a "clear coating" on it (seems...

How are you measuring pH? You can try building water with RO/Distilled + salts, to eliminate any potential water issues. Also, how are you measuring your temp? Where is the probe and have you verified it with another thermometer?
