Hello, can you help me with programming the esp32?
Hallo! I had an accident am looking for parts of bravo 350. I need only the plastic box of the control unit and the cable. Where i can order the parts?
Good morning.
I have a Bravo 300S rate control sprayer and Arag valves.
I have configured AgopenGPS and would like to configure session cutoff in valve control. I want to leave the Bravo 300S controlling the rate, and agopen only disconnects the session when there is overlap.
NOTE: I’m not sure if my valves are 3-wire or 2-wire with polarity reversal. (I’ll check this week)
But if I understand correctly, if the BRAVO 300S has the keys turned on, can I directly connect the agopengps wires to the valves (2 wires, polarity inversion) or just to the “green” wire on the valve?
Would it be safe to externally wire up the 12V control signal of the valve?
Berthoud or example had a connector that was basically an Y connection from the switch.
The switch or that connector could be used to provide 12V to the valves.
If that’s the case then putting 12V on that wire should also tell the monitor we have section on. That would be the simplest. This only works with 3 wire valves.
Be warned that some manufacturers who pull to ground when the switch is on the off position!! There this can’t work.
