If only one flow sensor is used the new firmware for the ESP32 relay 8 will control the master switch using sensor 2 motor driver. Set the relay type to master. M2A or M2B can power the switch. You have flow control and pressure control? The firmware would have to be changed again for this.
Sry. Download last pcbsetup and its works.
I only have one flow sensor connected to Flow1. I don’t understand what Relay 8 means. Is it meant to be like in the picture?
Yes that is correct. Now wire your master switch to M2A or M2B on the RC15 pinout.
It’s not working yet. I’ve connected it as follows:
Sections 1-5 => S1B-S5B
Flow sensor => Flow1
To simulate the flow sensor, I’ve attached an Arduino that generates the pulses.
Everything works up to this point. When I run it in the AOG simulator, there’s no power on pins M1A/M2A/M1B/M2B. Do I need to configure something else?
Can I connect the main valve and pressure regulator directly to the board, or do I need relays or motor drivers?
Product-> Rate: what is control type, what value is in sensor count/unit and base rate.
Product->mode: is 1?
Mode is set to 2 because I have a constant pressure valve assembly with bypass valves.
I also tried mode 1. And with different control types.
The flow control is working now. I had set the Min to 0 
. However, I still don’t have power to the main valve at M2A and M2B. Do I need to configure something else there?
- modules->config->sensor count =1
- machine->relays-> 8 relay is the M2 - set master/invert master to control main valve
Yes, I tried it with those settings. It doesn’t work. Is there a way to set a Min value for M2 somewhere? I’ve attached all the settings. Maybe someone can spot the problem.
Thanks for your help.

You say you have 5 section. Why you have 10+ section in Machine- relays?
What version of the app are you using? The new esp code may not work with that version.
Can someone help me with code? Or just explain is this possible. I try make row shutoff on maize seeder, with 12v motor with reverse polarity. What i understand i need just few sec power for each operation of motor instead motor can heat and burnout. Is possible change in firmware that rc15 give just few sec for open row then few sec to close it? Or its better to go with esp and relayboard or any idea you have. Thx
