Sounds good. I'll report anything I come across. I'm just glad the electronics confidence I've gained since getting BC wasn't destroyed by not getting this set up right. At least 45O is a great fallback. You = awesome

A few more connection fixes and I'm infact getting accurate enough PSI readings based on an old calibration and v45O. I'm so glad this has been sorted. No need for extra wiring for a secondary ESP32! I'll watch for your v46 fix. Thanks for following up!

You beat me to it! My TinyPICO was also reading 0 or 5. I went back to v45 and I had normal values. I was just posting a reply when you responded

In positive news, I found solder points on the board where I can control each relay externally, so my alternative may be to use a separate ESP32 interface to monitor and control pressure, then have one of its pins control a relay on this board. At least that frees up resources on each board.

Hah, sorry to have revived traumatic memories. I'm glad it's not some peculiar BC issue though. I ended up changing cold crash to 36. I'm testing my new Spike CF10 with internal cooling element and coolong jacket wrap to see how low I can get it, and I doubt it'll get past 38, but I'll let BC's...

Oh super interesting. I do have elements named with those numbers because I'm testing my new ESP board and I named them after their pins. That makes a lot of sense, I should have considered that (I forgot I had 32 as a name since I'm messing with 34 and 35). I would have assumed it would look...

@BrunDog Here's a fun one: Hysteresis seems to hate the numbers 32, 34, and 35 as target values. With my fermenters, I have a conditional to check whether I've set the fermenter to cold crash before the script does anything else. If my global "SP1 Cold Crash" is set to "Yes," then it will set...

I tried replicating this just now. I had a similar issue, but once I set the input device (1-wire in this case), it worked. It only failed to enable when no input device was set in the properties. I scripted it as: [test] if "35" value == 0 "PID 1" enabled = true print "PID 1 is enabled" endif...

Ah, yes. 0.000. Here is the device box and the communications window. Port 34.

At ~4.5 PSI in a keg, I'm reading 0.670v when I touch the red meter lead to the solder point for GPIO 34 on the ESP32 module (WROOM-32D, so 6th down on the left side when looking from top and no touch area up) and the black lead to a ground pin on the board. I get the same if I touch the red...

Very fair. The right voltage is at least making it to the solder point for GPIO 34 of the ESP32 module (measuring between that solder point and ground), but it's just not registering as a voltage. I'll keep tracing and seeing if anything else is messing with the signal. Otherwise, the form...

To add to the above, I measured between the connection point on the button and the solder point for GPIO 34 on the ESP32. I'm getting 0v, which I believe means there is a connection between the button and GPIO 34 since the current isn't flowing through the meter as a closed connection. This is...

I checked the Digital In of each button, but they show "On" as default and "Off" when pressed (using the default Digital Input settings, Active Low isn't enabled), which differs from what you said should be default... Measuring the voltage of the opposing pins on the buttons, there seems to be...

@BrunDog As an alternative to the above, I know the SPI input is geared toward RTD probes, but its calibration setup in BC looks like an analog input, with linear multiplier, offset, and such. Could an ADC SPI board be used with a pressure transducer? Or even a SPI pressure sensor/evaluation...

So good news, the boards did in fact arrive! D- for communication, A+ for the boards' arrival. All is pretty much setup now other than the analog pressure transducer since the buttons and relays take up the analog pins. I tried soldering to the left leg of button 1 (pin 34, a trace shows it...

Good timing since I'm getting the new ESP32 relay boards today. I might as well rework my math for my pressure tranducers as I set these up. Thanks for posting and clarifying this!

Nice! What I assume is mine is out for delivery right now. I guess I can forgive lack of communication and just know that if I order another, it'll show up magically, eventually, hah. Maybe I'll just order from AliExpress for a bit of reassurance.

This sounds ideal then for something like that then. This has its limitations with BC due to not having its own 5V pin, one relay being GPIO21, and it taking 3 minutes in setup mode since GPIO5 is a relay and getting pulled low at bootup. But its form factor is great, and it does work well so far.

So there may be hope here. I just got a USPS notification that a package was received from Cainiao, a logistics arm of the Alibaba Group. I have no other orders expected from China, nor any orders that aren't being tracked already. Not sure why the Robotdyn site offers no order updates and the...

I got the LILYGO TTGO Relay going in its first box, and all is working well so far. I ran wire to each relay's COM line underneath to cut down on wires running from port to port, and that works well. Edit: I also used the unusable relay's NC line to power my stepdowns. So not all is wasted...
