When you say you "pushed a change" , how do we apply said change? Latest update is still rc3, reload with that software?

Nah. It means I have developed the change required and it’s in master (from where next releas will be cut). So it will be out in 2.0. You have to wait till next release . We don’t support auto update yet

Looking for help on my build total newb here.

Im following the excellent guide on adafruit by Ranjib and im having problems controlling the american dj srp8.

Here are the problems im having.

1) after adding connector and eqipment to test i only heard the click on my intial on press.

Now there is no noise when toggeling off/on.

Only the channel 1 plug is working but it stays on.

None of the other channels are working.

Anyone can spot what i did wrong or what needs to be tested?

Thanks
Cory

Can't see all your connections but what voltage are you using to power the relay? I think you need 12 volts to power them, not 3.3v or 5v from the pi.

 

[Toby Lever]

Those relays can control most AC equipment across the globe . But they need 12v, how you plan to power the pi? We need your full bill of materials

The pi will be powered by a 5v 3A mains supply.
The relays will be powered by the 12v from the led light supply.

Is that cool?

Thanks for your help

@Ranjib, regarding the dashboard bug, I have just equipment showing as first picture, if I add a row as second picture and update and go back to dashboard, that's when the error shows "something went wrong" message gets stuck, but I just found out if I refresh and very quickly can hit the configure dashboard button(it flashes up and disappears very very fast) I can get back in and change it back and get a working dashboard, I'm running latest release and a pi0w.

Connect the grounds

I thought maybe my wiring was bad on the db9 adaptor so i simplified it and tried again.

Same thing. When i create the eqipment and go to test i hear the intial click but thats it. No off and on

Any suggestions on what or how i can troubleshoot?

Do you have a build thread, if not , it will be really helpful to start one. We can have the discussion coherently.
Now, back to your problem. Do you have multimeter? If you do , can you measure the voltage between GND and one of the input of ULN2803, when the corresponding equipment/outlet is on? You should see 3.3V. Next test the ULN2803 output. +Ve probe of the multimeter should be on 12V+ rail on the -Ve probe on ULN2803 output pin. It should read 12V.
Check the GND pin of ULN2803 is connected to 12V rail

Am I missing in your picture where the DB9-GND/COM is connected to the 12V rail? That would be your white wire correct?
Are they jumpered together on the bottom side of the breadboard?
Also are the 2x ground rails on the proto board connected? If not jumper them together.

voltage between GND and one of the input of ULN2803 = 1.4 volts so that doesnt seem right.

UNL2803 tested 12v at the bottom pin on 12v rail.

I circled what i tested because i wasnt sure if correct.

Last part about GND pin on rail i believe it is. Its the white cable

I tried to follow the guide 100% since i have no clue what im doing.

The white cable is the GND , the 12v wire from the barrel connector goes into the same row right above it.

Scrap that, the "something went wrong" message came back and can't hit the config button now lol

So I am trying to do some work on MACROS and ATOs my problem is that I would like to have an ATO shut my main pump off if for whatever reason my overflows get plugged and go to and the issue is that if i run a feed MACRO the ATO kick the pump back on when the ATO times out that is still low. I know I could add another relay to work in series with my pump so both would have to be on to make. But is there any other way around this. maybe add an option to set macros as a master to control relays and ATO as a secondary if not running a macro.
Thanks for the help

Wiring looks wrong to me, I don't see a ground connected to UNL2803a

In think the first part is correct i get 12v on the pin for the ground

Not sure what you mean by the 2x ground rails. Just to clarify run a wire from bottom ground rail to the top like so?


Thanks

Chip is in wrong way I think

 

[LionHeart2017]

See the notch out at top of chip, ground is left bottom, looks like your chip is this way up in your pictures but your ground is connected top right?

I have added some fixes to address this, but I am not sure if the bug is completely gone . But I’m fairly sure that now the dashboard bug won’t crash the whole ui or not let you navigate to other tabs . Let’s see

Okay this is probably exactly what I did wrong. I didn't know this chip went in a certain direction, I should have known.

Had to run to work but as soon as I get back I'm going to check this thank you so much everyone

I just pushed a change that will sort them by their creation order. Is it make sense to order them by name ?

I would say creation order because you can create them in the order you want them to be by name would kill my OCD lol they need to be in priority order. Just my 2 cents..
