RE: Unicon build series - Part 4?

That project indeed stalled. I literally have it partially completed as you've seen. The wiring was next and I just couldn't get to it with other priorities. How can I help you though?

@pbruno3 is it time to abandon all hope of getting Part 4?

RE: Reset Arduino from Brucontrol

Hi. Sorry, I'm not sure where you got a "reboot" command. There is not one currently in the firmware. And the code you have is not correct syntax... for example BC does not have a set command.

The reality of a microcontroller is that it cannot get into a funky state. It either runs or it doesn't, and if its not running, no software command would fix it.

If you are losing network connectivity, its likely something else than the code state. Likely either a power supply problem or a network one.

Reset Arduino from Brucontrol

Please can you advise? I'm monitoring and controling and steering fermentation with Brucontrol. Unfortunately, arduino's fall off from the network regularly. I have a protocol arduino_detection.bcs (runs inside BruControl every 60s)

→ checks MEGA.connected
→ sets Arduino1_Online = 1 or 0
→ can fires tx "MEGA" %N if offline
→ sets Arduino1_RebootFailed = 1 if still offline after 15s
↓ BruControl API
arduino_monitor.py (runs on your PC)
→ reads Arduino1_Online from API every 60s
→ logs OFFLINE / BACK ONLINE on state changes only.

FOR TESTING I would need the %N BruControl reboot command, can you please provide the %N reboot command? Tahnk you.

// Arduino Controller Monitor & Reboot

// File: arduino_detection.bcs

//

// Run this script on a timer (recommended: every 60 seconds)

//

// What it does:

// 1. Checks each Arduino controller's built-in .connected status

// 2. Updates Arduino1_Online / Arduino2_Online / Arduino3_Online globals

// (1 = online, 0 = offline) — Python reads these from the API

// 3. If a controller is offline, sends the reboot command

// 4. Waits 15s then checks if it recovered

// 5. Sets ArduinoX_RebootFailed = 1 if still offline after reboot

The Brucontrol script suggested

if == true

set = 1

set = 0

else

set = 0

tx "MEGA" %N // ← replace %N with reboot command

sleep 15000 // wait 15s for controller to reboot

if == true

set = 1

set = 0

else

set = 1 // flag for dashboard indicator

endif

//

//  NOTE: After replacing %N with the correct BruControl reboot command I can test it. Thank you in advnce for your support! Any other idea?

@pbruno3 Any hope of ever seeing Part 4?

RE: Hysteresis

Can you provide more details... what sensor is on which port?

Predictive isn't implemented yet... so you can ignore that.

Hysteresis

Lauran Casteleijn — Sun, 18 Feb 2024 19:48:26 +0000

Hi, I'm Lauran Casteleijn, and I'm testing and debugging the BruControl scripts. I'm using software version 1.1 (22). I'm using the Arduino Mega platform and all runs stable and nicely and I'm getting used to the BruControl interface. I changed from BCS including a hysteresis function that I was used to.

For BruControl, I have looked on the Internet for throubleshooting the hysteresis function but can't get it appropriately running. I have the following questions, please can you help?

1) I'm using version 1.1 (22) should I use Beta version 1.2?

2) I'm using port 18 and 19, DutyCycle is working fine, using port 18 and 19 for Hysteresis not

3) Target setting: 52 degrees, Offset -3 degrees, On delay 3 seconds (I don't exactly understand what will happen, can you please explain?) Predictive Hysteresis, (I don't exactly understand what will happen, can you please explain?)

Thank you in advance for your response, Best regards, Lauran Casteleijn

Is there any dead horse left to beat here?

Can you email us a screen shot of your PID element?

PID control not turning down output

Jason Thomas — Fri, 14 Apr 2023 02:24:36 +0000

I have my panel set up and doing water runs from am esp32. I have an Rtd temp measurement reading accurately and feeding its measurement into a PID controller. The PID controller appears to be working properly except it remains at 255 output even after passing target. The heating element just stays on because the output is staying at 255. Any insight as to what I might have set up wrong?

Thanks,

Jason
