Ok, so both pins you have tried are PWM outputs, and per the firmware notes will output as PWM: "PID and Deadband devices on pins with both Digital (D) and PWM Output (P) will use PWM Output." Try using a pin without PWM output like 5, 18, 19, or 23 and see if that fixes the issue.

Try increasing your calc and output times to 3 and 3. Also, can you specifically pull the firmware revision letter? O is the latest revision in the 45 generation and is what you should be running.

Yes control side you look fine, the one thing that catches my eye on that datasheet is where it says the relay coil operating current at 5V is 720ma. What is not clear is if that is the total current for all 8 relays being actuated at the same time or current draw for a single relay. If its a...

I'd need to see a schematic of the board in question to be sure, but typically the coils are driven via an external power source (Vcc) and control voltage from the arduino is separated. Sometimes there is a jumper involved to share or isolate power.

Hmm, it looks like that should be working ok. Have you tried a different pin on the board to rule it out? Also, what firmware are you running?

That is quite strange. Can you post what board and what pin you are using for control, as well as what kind of relay you are controlling?

Did you try with Kp around 20-30?

Hard to tell without an output trend, but I would bet you are experiencing intergal windup (Ki). Try setting that value lower. I'm not saying this value will work for you, but for reference, my Ki for my mash PID is .02 Also, increase your calc and output time. 5-10 seconds should be...

You can't span an if statement across [headers]

At 16:00:53, you can see it created a default config file, and 16:03:41 it loaded that default config, so whatever you did to try and restore the backup file didn't work. Change the file extension of the default.brucfg file to something else, then copy a backup file and name it exactly the...

That sounds very odd, what does the log say? It should look something like below if its opening properly.

Were you able to determine which workspace it was on? Also, scroll up and look for BackgroundImageIndex for that Element and make sure its set to 0. Looks like it should be on the left side of your screen about halfway down.

Open your default.brucfg file and do a search for the Element name you are looking for. It will tell you the X/Y coordinates of the element on the screen. You can also dig down into that file a little more and it'll tell you what workspace its on. Would be at least a place to start. **Don't...

OK, this is a little convoluted and I may be taking advantage of a bug/feature in the interpreter, but here is how I got that to work. It looks like you can't put a raw value to a time without it becoming a very large time value, but you can convert the value to a string and push the string...

Not sure how or what formula would be added, as this can already be scripted given you have all the proper variable inputs. //mg/l AA = (AA rating in decimal x oz of hops x 7490) / gallons of wort //Bigness factor = 1.65 x 0.000125^(wort gravity - 1) //Boil Time Factor = (1- 2.71828^(-0.04 x...

We should take this to PM to keep from cluttering the board, but it looks like you are still in XML format, and ideally you should be converted to JSON for easier data manipulation and transfer to BC. I'll PM you. Joe

So I think this was a poor coding practice on my part - taking advantage of the compiler that has now gotten more strict. I think all you need to do is declare the variable in the "BC Global Send" node by adding 'var' in front of each variable to be defined. Should be easy to find as the IDE...

I have not updated my node-red config in quite a while... I've been putting it off for this reason primarily. I'm going to do the upgrade today and I'll get back with you with the fix, I'm guessing its syntax. Joe

Not sure about Ispindel, but I believe the Tilt can.

I use a mass flow meter, though I suppose you could use a floating hydrometer type as long as it was somehow separated from grain and liquid flow disturbance.
