For pressure measurement, is there any advantage in using a separate ADC chip when using an esp32 or is that only really necessary for an esp8266 (when the adc analogRead() is occasionally interrupted when used by wifi). I understand the esp32 ADC is nonlinear but it appears to be reproducible...

I've been fermenting for five days now and found that if there's a gap in logging (my power supply was connected to the smart switch I use for Christmas tree lights :) then when you start up again there's a gap in the log. That's as expected. But if it happens a second time (because I am slow...

I think you'll need to assign a different pin for pressure monitoring (something other than the default GPIO 35) as that pin appears to be used for something else on that device (LRCK, something to do with audio), page 7 on the datasheet...

@akgal12 I cloned the main branch again and can open it (in chrome on ubuntu I'm opening file:///home/<rest of path>/BrewPiLessGx/extra/SkinEditor/index.htm )

Not sure why but I've not been able to get the pin for PTC cooler or capper to change state on one of my DS2413 (2channel 1-wire actuators controlled by PIN 22). The heater and cooler are on one DS2413, the capper and PTC are on the other. All four outputs are detected and configured in...

It's a one-wire DS18B20 (Beenlen waterproof sensor) same as the one in the thermowell for the beer temperature.

Cool! Once I realized I had to open the file extra/SkinEditor/index.htm in a browser it was easy. I made a table of the existing items and coordinates in a spreadsheet and another with what I wanted, then switched the coordinates and labels. I did have to re-add the touch screen "click"...

I checked my rj11 splitter and it has a jumper cable that was wired the wrong way around! Fixed that now and the probes all work via the splitter! For the glycol chiller I've ordered a 12V relay with spade connectors for the 120V side and I'll drive that relay with one of the two spare relays...

Thanks @day_trippr there's just two of them on 2m cables coming from the splitter which is three way with a 3" jumper cable to the rj11 socket then another 3" to the esp32. Not twisted pair. Good to know 2.2k works for a more challenging setup. It could be my cables aren't terminated well, it...

Yes losing synch due to network drop etc would be bad. Sounds like I should put a standalone relay board in the glycol chiller and control it from one of the DS2413 1-wire outputs I'm controlling on GPIO22. Thanks for steering me towards a more sensible approach! A related question: Do you...

I've got an "ESP32 2 Channel 5V Relay Module" with two built in relays to replace the STC-1000 in my IceMaster Max2 glycol chiller so I can control it remotely. (I can switch it on and off now using a switch on a web page). I am a novice at cpp and platformio. Is there an easy way to modify...

I was lucky, with my setup it worked more or less from the beginning. I'm sure it will be worth revisiting the project again once it has had a little time for the parts you need to slot into place. Good luck!

I totally agree, I think I'll try with two DS2413 on a breadboard with a 4 channel relay board. I thought I only needed one extra IO but I need two extra (heat and solenoid for pressure release). I'll probably put all the IO on one-wire (apart from the pressure gauge) so I can have all the wires...

Check the build_flags section for the env: you have set as default at the top of the platformio.ini file. For mine [env:ESP32_2432S032C], The line: -DTFT_FLIPPEDMIRRORED appears uncommented near the end like below. Maybe try removing that line if your "env" section uses it? (Sorry...

To get another IO, could you remove R4 and reroute IO26 to one of the speaker connections (after cutting that speaker connection track to U5)? Then tell BrewPiLess that IO26 is going to heater relay for example?

There's a flag -D TFT_FLIPPEDMIRRORED commented out in the platformio.ini file, maybe try again with that enabled?

That fixed it thanks, and the temperature control is working great!

Thanks for the quick fix @pocketmon ! I'm still seeing "invalid log" error with the updated BPLLogViewer.htm, it says it is 3 hours old but still shows v4.2 when I open it in chrome.

Hi @pocketmon , should the 4.2 logviewer be able to read the 4.4 logs (including pill)? I'm getting an "Invalid log" error when I try to read it into BPLLogViewer.htm I don't see a BPLLogViewerV2.htm in the htmljs/dist/english folder. (I tried disabling "Record Angle/Raw" but got same error)...

Yes that api is on the cloud side so doesn't help if data didn't made it there. The local solution works great.
