reef-pi :: An opensource reef tank controller based on Raspberry Pi.

[marekd1]

I know whats happening, this is a common issue when the reef-pi starts before network is up during power up or reboot. You can fix this by updating the systemd unit file for reef-pi to make sure it’s started after network is up

Cause a script to execute after networking has started?

I am relatively new to systemd and am learning its architecture. Right now, I'm trying to figure out how to cause a custom shell script to run. This script needs to run after the networking layer ...

Happy New Year!!! Thank you, Ranjib, I will give this a try.

Out of curiosity, has anyone integrated alkatronic into reef pi? I'm curious if I can just add an extra ph probe connector, if the data sent is the alk number.

Wondering if anybody can help me out with this. Installed first temp sensor for my build (pi4, reef-pi 4.0). The temp sensor seems like it’s definitely working because it’s showing the temp in the calibrate screen, and it seems to be accurately responding to changes.
However I’m getting errors in the dashboard and in the “edit” menu for the temp sensor.
Thank you

Edit: Thought Id figured it out but I hadn’t

Dashboard error was caused by not selecting sensor. Not sure why I only get one chance to set up the temp probe and then it throws an error every time afterwards

Realized the issue with temp throwing an error at edit is caused by iOS internet browsers. Doesn’t have the issue when using a PC browser to access the reef-pi gui

It should work properly in landscape, the same issue is also on Android.

Oh brother, thanks that worked

Hi
I'm having a simple problem, I can't get this test macro to run
when i press run it stays in blue frame (pic 2), and as you see in pic 3 the doser 1 is still off
is there anything that I'm missing
if i try similar macro with equipment it works fine

 

[stefanm]

Is the doser pump on in equipment? You need two affiliations for each pump head for it to work, one in outlets and the other in jacks. Please see the attached screenshots. The one that you set in outlets should be permanently on, the other in jacks is set by the timer under the doser tab.

The next three images should help also.

Mine are switched off right now as my return pump has conked off

Still need some help with the HS300 stability. I can't get it to connect after a reboot without reloading reef-pi.

The after/ wants suggestion wasn't working, so I also added a delay to the service to sleep until we get a ping from the HS300. That didn't fix it either. My reef-pi.service file is below, do you see anything wrong?

Something else of note, I can't figure out why I am getting two mac addresses from the pi4 and it seems to be a toss-up on which one gets called after a reboot. From what I read, pi's have different mac addresses for the ethernet and wifi connections, but I have never even plugged the ethernet in. Thoughts?

[Ranjib]

Your unit file looks ok. The dual WiFi MAC address for same pi is concern. Are you changing hostname? Is it possible you have two pi with same name ?

Thanks for checking the file.
Hmm I did change the host name per the setup docs but I only own this one pi.

Maybe I need to re-flash the drive or try spoofing the MAC so it’s always the same

Thanks for your reply
I have the doser only in Jacks and non in outlets
It is working fine, however i wanted to turn the channel off for extra security while not in use and then turn it on just before the next dose time using macros and times
There is a doser option in the Macros so i though it would work but it seems that i need to add it to outlet for that to work

I'm not following you completely, but in almost two years I can safely state that reef-pi dosing has behaved impeccably, any issues have been user error! (It wasn't me)

Has anyone messed around with ngrok or thought about making a reefpi plugin for it? I was setting up my octopi and ran across an article for accessing it from outside the network. Rather than forwarding ports ngrok establishes a secure tunnel. A single session account is free and you don’t have to forward any ports in your router. You access it from their cloud account. It was easy to setup in octopi because it has a plug-in.

ngrok works great. I'm not familiar with octopi though?

Personally, I use wireguard tunnels to bridge networks together, but it still takes a bit of network planning to get that setup.

 

[Ranjib]

ngrok, port forwarding, vpn all works. they all have their pros and cons. you should be able to use whatever you are comfortable with. Port forwarding is easiest for me as I do it within google wifi app , on demand, so just enable it when needed , used the app and then disable it back again.

Octopi is raspbian OS derivative with baked in octoprint (3d printer web UI). I prefer to use octoprint straing on whatever the current raspbian/raspberry os is.
