Hi i would like to make a fully functioning hydroponic system
it states 2x ADC are stackable but is 2xADC + 2 x relay stackable? this is my preference

if not is 1x ADC + 1xRelay stackable ? as i will split, one omega running air/light, the other running water control and ph etc

Would like to achieve
analogue measuring air temperature, water temperature, ph level water (uses 2 x analog) , humidity, water level
relay control fan, 2x lights, water pump, 2 x Peristaltic pumps

possibly something i have missed

most good examples of fully functional hydroponic controllers use arduino mega or similar
i have an omega2+ as well as most expanisons needed ( i will need to buy an ADC )
so was looking to utilize what i have

thanks

Awesome thank you

these will be very helpful for anyone using node red with the expansions

hi

i have node red working on omega fine
I found this website with nodes specifically designed to run expansions for omega
how do i create nodes using this data ? i have downloaded and installed nodes ( i downloaded the underground weather node) but i don't understand how i can create nodes using this
could someone help please?

hi guys
im going through the prerequisites to get node red running
which is to get a swap file created and to run on boot as well as getting extra storage to also run on boot
i get swap file to start on boot but when i had the extra storage(create overlay) and editing the fstab again it stops autobooting swap file

i suspect my /etc/config/fstab file configuration is incorrect, i have played with a it a bunch of times

can someone show me what theres looks like? or look at the below tell me what looks wrong?

config global
option anon_swap '0'
option anon_mount '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '5'
option check_fs '0'

config mount
option target '/overlay'
option uuid '7affdca6-de72-d201-607e-######'
option enabled '1'

config mount
option target        /dev/mmcblk0p1
option uuid '7affdca6-de72-d201-607e-#####'
option fstype        ext4
option options       rw,sync
option enabled       1
option enabled_fsck  0

omg that worked
got some more stuff to say but yes that worked
i suppose why do i need to ask for help, why is it so broken

i copied your link
its doing the folder/file repeating thing !
copying for ever duplicating folders over and over again

suggestions?

cool bro super helpful

your exactly right i don't understand what is going on and im trying to hense the email
no thats really good info , and i made assumptions if one functions is working from a inserted device i assume another would

it is mounted to /mnt which is the odd part, i am not simply copying and pasting tutorial links, but i am making sure the path matches and file name is correct, i mean getting the swap file to work was quite eye opening in that regard going through the process and as i am doing now i had to ask as every step seemed to be broken

is there a mount check? i mean its mounted i am using it as a swap file so how can i see if it isn't mounted correctly

sorry if i seem like a dick too,

@WereCatf

on no sorry bro i wasn't meaning anything, i just assumed it couldn't be related , my thinking- if i can access it why would it create extra folders because it was mounted badly, as it is accessible/mounted correctly - im too used to dealing with windows related stuff , i didn't know that bad mounted drive cause copy functions to misbehave but allow full access otherwise? is that a thing?
ok cool i will focus on the mount see if that helps
thanks heaps

but bro it seems weird, as i am going through the node red/omega set up
you need extra swap memory and accessible storage
i have the swap memory working on the mounted sd card so device is accessing card fine and on boot, now moving to the process of extend the storage
now if the swap file is working and working on boot which it is, i would think the card is mounted correctly?
or am i wrong
so im thinking its possibly not a mount issue? i don't know asking @WereCatf as yourve been super helpful

@WereCatf
its actually the inbuilt micro sd card i am using of the omega2+

well thats the other problem, is that its dis mounting randomly
but i have tried the same process go to the same point with a usb and the same thing its dis mounting randomly

however isn't that a seperate issue?

ii mean thats a problem, but how is that the same problem as the device copying folders within folders on an never ending copy process
i don't believe that bad mounted usb would cause a copy function to copy itself again and again
thats a software issue surely?

@Leo-de-Blaauw
im sorry but im super glad you are also experiencing the same issue
honestly i havn't done one step of anything in my omega experience without coming across what seems as an issue , i just don't know if i am doing stuff wrong or something is broken, please let me know if you fix it!!

@Kit-Bishop
yes all your steps mentioned i followed as per tutorial, my device is formatted ext4, one of those things where i followed the steps to format it to ext4 via omega and it didn't work, so i plugged it into my pc downloaded something formatted to ext4 that way then it worked

i got to step 3 i believe and the copy process was doing weirdness creating extra folders within its self

i am sorry i want this to work and just getting annoyed , i am trying to run node red, im doing all this stuff to make the device capable of being able to support it and its been 2 weeks i am moving at the pace of a glacier because of nothing seems to work and i am relying on help from you awesome people and when you have the time to reply to my ranting emails super sorry love you guys

super frustrating every step to do anything doesn't work as per tutorial

but anyway Step 3 on this
https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs
which is to create extra storage, i type this in as per tutorial

mount /dev/sda1 /mnt ; tar -C /overlay -cvf - . | tar -C /mnt -xf - ; umount /mnt

and its creating mnt/upper folders repeatably within it self for the same copied items and keeps repeating until the point its mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper/mnt/upper...............
the copying process does not end and every second/minute what ever it simply adds an extra file mnt/upper so it simply gets bigger and bigger

could someone please help me with what is wrong with the command?

thank you

hi @WereCatf

i think i had 2 issues and because im inexperienced was hard to identify which

first issue is (this one resolved) the command swapon was not installed with swap_utlis (following the tutorial)
and as you said block-mount (which is the solution) had it, but not part of the tutorial or packages accessible without changing a file so i was supper confused and had to google the hell out of it, but i got there thanks to another post

but i mean logically swapon should be part of swap_utils right? i mean that would make sense
but as i said this is fixed as i followed some advice on how to access okpg that wasn't available as a normal package
so thanks for that

secondly dunno my microsd keeps becoming un accessible, i actually think its random and not associated with the command error, however it was still under the temp directory as i wasn't mounting it on startup - maybe that was the issue

so my next step was now that i can make a USB swap file and now that i can make it automatically mount on boot ( which was actually the tutorial to use USB not SD) i was going to try the whole thing again with SD

i really appreciate your response, i think because its in such an early stage and im inexperienced i struggle to tell if i am doing somehting incorrect or its broken, so knowing you have it going helps alot

oh excellent
sorry looks like you had already answered this i need to improve my searching skills

but obviously needs to be added to the swap-utlis as per tutorial (and makes logical sense)

thanks for helping me out

swapon isn't part of swap-utils and not part of any of the other packages (identified by opkg -list)

could someone confirm and can i download it somehow and install it, how would i do that?

my last post was more around my sd card constantly dismounting when i type in 'swapon'
this post is specifically around i don't have swapon when i have installed the swap opkg
my apoligise if i should of left it as one post

Hi

i did the exact same process with USB

USB isn't dismounting however 'swapon' command doesn't seem to work? same as the sd problem
i was hoping to at least get the swap file to work on USB then i can repeat process with SD

so focusing on the 'swapon' command issue

error i am seeing is -ash: swapon: not found

which is the same error i get if i type in a failed command

and to be clear i have installed this
opkg update
opkg install swap-utils

is there another package to install perhaps? i wouldn't know how to find it

or has anyone got any suggestions on trouble shooting initiating swap ?

Hi

i mentioned this in another post, but it was a reply to another OP problem so shouldn't of

https://wiki.onion.io/Tutorials/Extending-RAM-with-a-swap-file

as i go through step by step in this tutorial, which is to extend the ram by making a swap file on your USB
which i am doing it on my microsd instead to free up the usb port, perhaps this is the problem?
i create the swap file of 256 MIB fine
But typing in 'swapon' and the directing to the swap.page
i get -ash: swapon: not found
and the sd card is no longer accessible via df -h
to get it visible i have eject and re-insert sd card (some times multiple times)

microsd has been formatted to ext4

any suggestions on what i could try?

thinking about this logically
if i have a micro sd card inserted in the builtin dock of omega 2+ and i can see it by typing 'df' into command prompt
and then not do anything but wait 2 minutes, type 'df' again and i can't see the sd card
is this right or wrong ( only reason i can think of, of why it would automatically not show is if it was automatically dismounting because of no activity) otherwise i think its broken, which im guessing it is

secondly, command 'swapon' i don't think according to the documentation should come up with swapon: not found
i mean to get to the point of initiating the swap file i used 'mkswap' which worked, swap file is working i just can't get that one command to work, why

i just don't know if im doing something wrong, the documentation is wrong, or the device is broken
so frustrating for new users, not one step has worked correctly yet

hi

i am attempting to utilize the micro sd card (as i have an omega2+ built in micro sd card) to create extra storage and virtual ram
so frustrating everything seems super fragile, takes lots of attempts
again took me along time to even identify the sd card, following the tutorial to format ext4 didn't work
i had to download a windows formater stick the card direct into my pc to do it

but anyways sorry about the rant
i found the sd card (not where documentation directed me) but by typing in 'df' into command line
found the command 'df' by randomly googling it, i couldn't find command 'df' in help docs
now for some reason my omega keeps dropping the mounted sd
i can see it, i can see where the file is, then i try and do something to it and it can't access that file
i do 'df' again and it is gone!!!
so i eject it and reinsert if 'df' and its back ... sometimes
super frustrating
finally got to creating swapfile (extending the built in ram this is to get enough ram to run node red)
by following documentation

following the documentation i get to this point
the command 'swapon' (which was the next tutorial step) to initiate the swap file comes up as an error !!

-ash: swapon: not found

here is the command i typed in
swapon /tmp/run/mountd/mmcblk0p1/swap.page

can someone please help ? what is wrong with that command and why is the micro sd constantly dropping ? when i say constantly it can stay up for 2 minutes or10 seconds - not sure if it doesn't like a failed command and it drops it, or it just drops by itself, from what i can see it seems to be random

sorry guys i really want this to work

guys trying to utilize the microsd slot to expand storage and ram
no idea how to even see omega can access it, i can't se it anywhere obvious

what do i do in terminal to format
how do i know what it is called
