Hey @BrunDog, at the end of the podcast you and Bryan were talking about graphing multiple variables and being able to pull up past data. Are you guys planning to implement a device/element that would act as a "BruLog"? Essentially, an element that we could "start" a brew day, write notes, and...

For 1-wire, your sensor readings will be within 1F of the actual temperature at the probe location (if mash temp at that spot is 150F, you will read between 149.1-150.9F. out of the box). Now, regardless what probe you are using, move the location by 6 inches and you have a different temp. For...

For the ds18b20 1wire temp sensor the 12 bit resolution is 0.0625 C step size and the accuracy is +/- 0.5C.

Yeah, I have done this. They are so cheap, I bought 10 when I need 4 for now. Also, you can buy a cheap lipo board module to convert the ESP32 to battery of you want. Would prob cost like 2 dollars shipped. eBay or AliExpress has plenty. Are your DC and mkii ac gnded together? Have you tried...

To add to this, the biggest advantage IMO of the ds18b20 is no calibration needed. They are spec'ed out of the box to be accurate within +\- 0.5c in the range of -10 c to 85c.

Looks good at first glance. I'll have some more testing tomorrow.

Yes, the ESP32 can be an interface over wifi. You just add a new interface and use network instead of serial.

Interesting, I am using the newest firmware 45E on a NodeMcu board. I will try an older firmware version. Edit: I reverted the board to 45C and it works as intended. Must be a bug in the new firmware. Probably an updated library or something.

I wasn't using GPIO0, I tried all the supported pins. I also had nothing connected to the board. On the ESP8266 (and the ESP32 for that matter), there are certain pins that are pulled high at boot/output a pwm signal/or cause boot failure if pulled low. See...

Is there an issue with Counters and the ESP8266? I have a esp connected via wifi, but if I add a counter element, it does not respond and keeps in a reboot loop... termite serial debugging says "ISR not in IRAM!", then it says Abort and reboots. Edit: Probably a relevant link for @BrunDog...

There is also this.... https://www.homebrewtalk.com/forum/threads/tiltbridge-tilt-to-wifi-device-for-tilt-hydrometer.664368/ That is really weird about the wall bricks. They should be providing at least 500mA which is plenty for am ESP32 board. I would check the to see their output.

Not sure, but it would probably be cheaper to just plug in an Esp32 at every fermenter that uses a tilt.

Yes, it literally is a radio signal.

The ESP32 is significantly more powerful than the 8266. The way the wifi stack is handled in each of the hardware platforms will be different, so its probably a hardware driven problem. Typically very similar code can be used between these boards, as most are compatible in the Arduino...

En is reset, boot is for flashing firmware.... You typically have to hold down that button when you start the upload until it connects.

I will not be able to test this for about a week due to the holidays/traveling/etc. Will report back...

One my ESP32, I have DC Pump PWM pins set up on pins 16 and 17. While pin 16 behaves as expected, pin 17 displays some weird behavior. I can change the PWM value, but when 0 is entered, it remains at its last value and does not shut off. Disabling the PWM element does not turn it off. The only...

No. You will need to power your ESP32 with a 5v USB charger. The ESP32 connects to brucontrol over your WiFi. There is no wire to your mega.

The ESP32 is like a small mega, but has wifi and bluetooth built into it. You can get them from ebay/china for like <$5 each, or through amazon for like $7 each...

Anyone using an ESP32 with more than 2 onewire probes? Edit: my 4 OneWire sensors work fine with my mega, but with the ESP32 I am getting wrong readings. They are shifted high. My guess is there is some sort of bit shift happening. Example, I should get 60f and reading 100f. I had been reading...
