New install on Pi Zero v2.0. I'm able to calibrate doser pumps and run, but during schedule i'm getting error
May 09 17:44:04 pi reef-pi[213]: 2018/05/09 17:44:04 doser sub system: setting pwm pin: 8 at speed 42
May 09 17:44:04 pi reef-pi[213]: 2018/05/09 17:44:04 ERROR: dosing sub-system. Failed to control jack. Error: Item '' does not exist in bucket 'jacks'

From your error it looks like your dosing pump is not associated a with

using the pca9685 on pins 8,9,10,11 just making sure my choice of gpio pins wasn't the issues.

on another note is the any sort of donation or something setup to further this project

the error is related to the fact that the doser is missing a jack information. If possible can you delete it from the ui and recreate it.
I already found a separate bug on doser sub system, I’ll patch it tonight

We don’t have any donation . You are helping the project by testing it out, that’s a big help

Thanks Ranjib, it's working now but the max temperature in the control cannot do anything to it.

Did you try clicking the edit button, that should allow you to update max temp and all other details

I've tried 3 installations on v2.0 with same issue, I'm using the raspberry pi zero w with reef-pi-2.0.0-beta-pi0.deb

I've tried 3 installations on v2.0 with same issue, I'm using the raspberry pi zero w with reef-pi-2.0.0-beta-pi0.deb

So all these three issues are exactly related to the doser ?

Can you try this, from command line (if you are familiar with command line linux )

curl -u reef-pi:reef-pi http://10.0.0.10/api/doser/pumps

change the -u reef-pi:reef-pi to appropriate username & password you are using. And also change the IP from 10.0.0.10 with your pi's IP.
This command should give you the details of your dosing pump (details that are not visible in the UI), we can fix it from there

 

[Ranjib]

For example here is the output on my dev setup (not at home, so no access to my reef-pi builds right now)
The api command has syntax of

curl -u username:password  http://reef-pi-IP/api/doser/pumps

To list all the dosers

curl -u reef-pi:reef-pi http://localhost:8080/api/doser/pumps

This gives me a list of dosers (i have only one defined right now)

[{"id":"1","name":"Two Part - CaCO3","jack":"1","pin":0,"regiment":{"enable":true,"schedule":{"day":"*","hour":"1,9,17","minute":"1","second":"1"},"duration":15,"speed":0}}]

To delete a specific doser, we make the api call with specific ID (obtained from the previous command)

curl -u reef-pi:reef-pi -X DELETE http://localhost:8080/api/doser/pumps/1

You can now re-create the doser, make sure to choose Jack and pin correctly.

I am sharing this as I figured out that deleting doser from UI is broken due to a bug.
It will be very helpful if you can re-create the pump from the UI and take screen shot (and share it) when you specify the jack and pin details

pi@pi:~ $ curl -u reef-pi:reef-pi http://192.168.1.100/api/doser/pumps

[{"id":"1","name":"D1","jack":"1","pin":8,"regiment":{"enable":true,"schedule":{"day":"*","hour":"*","minute":"*","second":"*/4"},"duration":2,"speed":42}},{"id":"2","name":"D2","jack":"1","pin":9,"regiment":{"enable":false,"schedule":{"day":"","hour":"","minute":"","second":""},"duration":0,"speed":0}},{"id":"3","name":"D3","jack":"1","pin":10,"regiment":{"enable":false,"schedule":{"day":"","hour":"","minute":"","second":""},"duration":0,"speed":0}},{"id":"4","name":"D4","jack":"1","pin":11,"regiment":{"enable":false,"schedule":{"day":"","hour":"","minute":"","second":""},"duration":0,"speed":0}}]
pi@pi:~ $

all doser pins where selected correctly. I have noticed problems with removing from UI, but i write a clean copy of raspbian and delete browser data each install

screen shot

 

[Ranjib]

So, you have declared 4 dosers. All are connected to a single jack, and the jack has 4 pins. Do you have the jack defined? whats the output of

curl -u reef-pi:reef-pi http://10.0.0.10/api/jacks

I am asking this because the original error was about missing jack

 

[Greg456]

i am familiar with command line and linux. only OS i use outside of work. i have several headless systems

screen shot

I mean the screen shot of the UI when you are defining the doser. Here is an example:

Thats a relief :-) appreciate being patience during the troubleshooting.

The original error inidicated that the dosing pump had no jack associated with it,

ERROR: dosing sub-system. Failed to control jack. Error: Item '' does not exist in bucket 'jacks'

the empty quote '' indicates this. But your api response is showing that the pumps have a jack set (ID: 1). Do you see the same error again?

Hi Chris :-)

I have the same issue with delete button on dosers.. at the moment its not a issue for me as i am building circuit boards for other parts.

Relay circuit it complete . Today I am going to build the temp circuits and experiment on what cable length can work . I need two temp sensors 20 feet of cable away from where i want to put the reef-pi controller

Thats pretty long. I have tested as far as 6 feet only.

Thats pretty long. I have tested as far as 6 feet only.

If its to long i wonder if the signal could be amplified, Or would it (my best guess) Use a pi-zero as a separate controller for my RODI -Water change stuff.

I will test today or tomorrow and let you know if it worked that far..
