Gotcha. Not typical, doesn't provide any real benefit or additional safety to have 2 SSRs here. Should always disconnect element when not monitored physically - either appropriate DPST or DPDT contactor or simply unplug it (that's what I do). But anyways, I would just connect the SSRs directly...

@tzacher It's cool. Do you use 2 SSRs for one element? Try connecting the SSRs directly to your pi (assuming the control signal for them is 3-32VDC, they will probably work fine). Those relay modules are often used to control things like pumps, lights, etc. Not useless by a long shot, but...

@tzacher Not entirely accurate statement. Don't use PWM with a relay board. It's possible to use PID without using PWM necessarily (not common on "hot side", but brewpi logic is a common example of this...). That being said, why are you using a relay board to control SSRs? At most you should...

@jjkeegan86 @tzacher Don't use a PID for boiling, set the element duty manually for that or try the PIDBoil plugin perhaps. @jjkeegan86 Overshooting is a reflection of your PID tuning.

It looks like the actors included with CBPi3 actually use RPi.GPIO. You can easily write a plugin that provides actors using wiringpi though or uses the nanopi port of RPi.GPIO

It looks like the description I added to the plugins list made it invalid (use of colon), but that has been fixed...

It's okay to give up on the tuning! Especially if you're not doing stepped mashes, regular single PID is good enough for pretty much everyone. I'll let you know if I incorporate autotune. I added some new documentation and renamed my plugin Cascade Control on account of the new hysteresis...

Same pin out, yeah I use D1-mini pro it looks (the one in my desk right now anyways). I am using BrewPiLess.v3.5.thorrax.newui.4m2m.bin - I had just assumed this was a build that worked with @Thorrak 's boards. I flashed with esptool.py, worked first time. I don't have any OLEDs to test, just...

For those using CascadePID, there is a development fork of the plugin you may be interested in. There's some features in there for hysteresis and a PID-hysteresis cascade which is what you'd use if you had like a gas powered HLT and were running a HERMS. This will continue to be a development...

I have some pictures and details of my fermentation controller build on my brewing blog if anybody is interested. The PCB I use was based heavily on @Thorrak 's design with lots of help from @day_trippr to carry out my changes (saved me lots of headache I am sure). I've been using brewpiless...

Some use 3k3, but you should be just fine with the 4k7 in your scenario. Using 1k may be sinking more current than is helpful in terms of reliability. I am assuming you have things working with either single temp probe. Sometimes the leads are mislabelled if you bought pre-built sensors, always...

Did you try resetting the EEPROM? It can be found under "configure device".

@Quadrider are those mounting brackets for the CFC in your first image? edit: nevermind, I see they are for the basket. With the size of the CFC it looks like one should plan to purge every bit of wort out of it at the end of the brew with gas of some kind, or plan to mount it high in a way...

Check out node-red, it can be used with arduino. I used it to create a brewery control and a dashboard quickly for my RIMS brewery (volume sensing, PID, manual element control and pump switches, etc.) https://nodered.org/docs/hardware/arduino

I don't think there's a CBPi limit, but you may run out with the raspberry pi, which would mean you'd be using some kind of GPIO expansion board in conjunction with it, which would probably mean writing your own plugin. Widgetlords may have some stuff that interests you. The plugins are pretty...

I do this - I use vagrant - but Ive also done with virtualbox. No issues. The only thing I haven't tried yet is flashing ESP8266s - but looks like it's doable...

If these are 1 wire temperature sensors, you can run like 100 of them off a single GPIO pin.

I'm experienced with pandas, but not web/app development type of stuff so much. You're thinking like some kind of "log editor" feature though? I imagine it'd come down to just removing data within a specified time interval right?

If you do have non default device constants, you can post them here and we can let you know if anything looks funky... based on the plot the chamber temperature is following the chamber set point quite well, so that’d be my guess. Or just reset the device constants to the defaults.

If I had to guess I’d say you have a stuck relay - those cheap relay modules I find to be very susceptible to such issues. Alternatively, if you changed your device constants that could also explain a change in behaviour.
