My next thought after checking connections would be to replace the resistor if you have any spares on hand. Since you haven't updated BC or the firmware, their versions should be aligned (we are up to firmware v46 now, with an updated BC), so there shouldn't be an issue there. After contacts...

The -197 tells me it's still a bad signal. Is the resistor the same one from before? And you said you still have version of BC as before. Is that the same case for the ESP32? Same as before with same firmware?

Do your probes have end connections (like an audio jack or other plugable device)? Or even a hub that you wired together? If so, it may be worth checking the solder/crimp connections. I had to do that on one probe after putting it away and pulling it out later. A solder connection came loose...

I've had it happen on one controller a few times this week. Looking at my graphs, it has consistently happened when my max high offset temp was reached, indicating it happens around the time my associated glycol pump (24W, I assume 12V 2A) should be kicking on (but not every time of this...

Hopefully that doesn't happen much now. I likely shared enough to indicate that I read the manual; it's just a lot to take in or things get buried (or my blind @$$ misses something I wish I had seen a while ago). Seriously, I want a refund on my glasses and contacts. Or maybe I shouldn't sample...

Thanks! Still good to see. This method has worked well. I have it start a timer and wait for the connection to come back. If it doesn't come back after a minute, it sets the alarm series. If the connection comes back, then the timer stops and reset. I still can't believe I've missed seeing...

No battery terminal, unfortunately. Just 110v AC or 12–24v DC (and UART pins for upload). Nice on the Feather. I considered it first when I got BC, but the performance of the ESP32 gave me ideas for other projects, so it became my default MCU. I've been meaning to play with the power-on...

If so, it didn't effect the other unit. Both run off the same power strip. Checking the interface logs and other BC events around the time of the last freeze, I don't see anything out of the ordinary, so it does feel somehow hardware/power related. I note my keezer and glycol chiller are on the...

Yeah, the board was unresponsive and seemingly not functional. No device updated on BC, and the board wasn't showing on WiFi. I just unplugged and plugged it back in, then it worked. My other fermenter's control board did the same last night, but my script alerted me, and I quickly resolved it...

Hysteresis for those. But I have a script that watches my Tilt average and will set temp and pressure targets based on % of expected attenuation.

So my above idea worked out. I have a jumper between two pins, with one being Digital Out (DO) and the other Digital In (DI). I have a first script that flips DO on/off (depending on current state), then it waits 3 seconds. If DI != DO, then it starts a timer and waits for DI == DO. Otherwise...

Does anyone have a script to detect if an interface is down? I had an issue last night where a control interface for a fermenter (ESP32 on an integrated relay board) seems to have frozen. I woke up and saw a sudden drop in gravity overnight (my Tilt interface is a separate ESP32 so it can sit...

Yeah, the feature of all pins being capable of digital or analog will be nice when this chip starts appearing on integrated boards like the LILYGO TTGO or Robotdyn R4; no more hoping they didn't eat up the analog ports.

What about this board stands out most to you? I was reading about it the other day. Onboard USB sounds nice for other applications, and the increased I/O could be good for BC if someone has a complicated setup with a lot of devices.

I just wired my second fermentation controller setup with another Robotdyn and loaded ESP32 FW v46D. All worked right from the get-go, so v46D seems to be stable, at least with 1-wire, analog input readings, relay controls, and BC comms.

@BrunDog Alright, it came online quickly this time. And all three hysteresis devices (2 controlled by 1-wire, one by analog input) work as expected. Nice quick work!

I thought that, but I didn't see it come online. I'll run it again

I can install the firmware but I can't get to the setup mode in Termite. Went back to 45O and it works, so 46D may have an issue with setup. I'll try updating over WiFi Update: WiFi update didn't play nice. No connect. Going back to 45O now

@BrunDog TLDR, hysteresis for cooling and heating with 1-wire input aren't acting right on FW v46C. There may be some communications issues regarding hysteresis devices with FW v46C. I was able to get my analog sensor set up and have my hysteresis device (solenoid) working great with Active...

I can confirm that analog pins for ESP32 are good to go on 46C. I've reworked my math with the 12 bit ADC and have it tuned quite nicely. This relay board is a dream now!
