You don't want to power the yellow (data) wire, only want the pullup resistor at 3.3v which you likely have already. If so, just move the red + wire to +5v.

Yeah the sensors work better at 5v, as long as the pullup is going to 3.3v the Pi 3.3v tolerant pin will be ok.
Perfect!
3 days ago I changed for the second time my power supply and it hasn't failed so far (this time it's s 3 amp power supply). If it does fail again I'll try to change the voltage, thanks!!!!
I'll keep you posted haha :)

Hi all

my dsb temp sensors keep on disappearing from the sensor list. Any ideas please?

I've been having some problems with the DS18B20's myself lately. Can you see the sensor on the W1 bus folder?
It does seem like a sensor issue. As my old one works fine from a hardware perspective. From a ReefPi perspective though I am still getting this error on the temp tab.

Bought a new sensor today and working fine. So def was a sensor issue. But not sorted out reef pi. Can anyone help?

Hey fellow Reefers & DIYers!

I ran into an issue with my robotank running reefpi 4.0.
I usually access it through my IP address and as of yesterday I can’t access it, it won’t open and when I unplug the pi and plug it back in after a min or two it would let me access it but soon after it stops letting me in.

I wonder if this is a pi issue, reefpi bug or my internet? When I can’t access it I do see it connected to the internet when I check the devices online so I’m a little confused.

btw I been running it for like 5-6 months without issues.

Is it pulling the same IP address every time?
Maybe your router is giving it a different address once in a while.

Some routers let you give devices a fixed IP, dig around in your dhcp settings perhaps and see

Hi there! I fixed it, I rebooted the router and it’s been working fine the rest of the day so my guess is the router was bugging out a bit

Great. After pulling everything out of the cabinet, resoldering new temp sensors to plugs, undoing all the silicon sealant to look for rust, i just found out that i must have just plugged in the jumper wires back in offset by 1 pin into the pi at some point

I hate myself

Cheapo ds18b20 potted in silicon and cocktail straws still doing fine and no rust after a year and a half btw

We all have been there. bunch of us have burned finger by writing that sensor opposite. Trust me, in later years you'll laugh in retrospect. This is a complicated project.

I've got 2 exciting things to share!

First off, I just listed Leviathan 1.1 for pre-order! The biggest roadblock for people using Leviathan 1.0 was dealing with multiple power supplies & buck converters. Leviathan 1.1 has on-board power regulation, meaning you just have to give it 12V & the board does all the work to get the 10V & 5V signals where they need to be. It's got a few more ports & an all-around "cleaner" look as well, since I was able to plan this one out from scratch with the learning experience of 1.0.

To celebrate, I'm running a giveaway on my site to win all sorts of cool stuff including Raspberry Pis with Reef-Pi pre-loaded & programmed, an Aquatic Life 100 GPD RODI filter system, & of course the Leviathan 1.1 board itself.

Second, I've finally got my build thread populated now & I thought ya'll would appreciate the canopy I laser-etched for it. It was my first large-scale laser project & I'm super happy with how it turned out. The graphic is one I designed of a fish wrapped around Knoxville's Sunsphere.

It's been a wild ride the past few years going from virtually zero electronics experience to designing & buildings hundreds of these boards. But it's been super rewarding seeing the growth of Reef-Pi as both a program & a community! My aquarium inhabitants owe you (quite literally) their lives Ranjib! Without Reef-Pi, I'm positive I would have given up on my tank after a year or two of things like daily manual top-offs & physically unplugging pumps & powerheads for every feeding & water change.

Have you confirmed that reef-pi is running at all?

sudo systemctl status reef-pi.service (not exactly sure if the last part is spelled correctly, best to use autocomplete for that)

And is there anything else besides reef-pi on the pi?
Hey Sorry i just saw this. Still an issue. I ran this command and it says its running, but I know reef-pi is running because everything is working. lights are on schedule, and stuff turns on and off. That is why i haven't done anything with this, its currently working and I am prepared to spin up a new Reef-pi install but would much prefer not to have to redo everything. I did notice that in that status report it mentioned the starting the http server at: 0.0.0.0:80. Is correct?

Thanks

when you connect a monitor to the pi, open a web browser and put in "localhost" as the adress, do you also get connection refused?

I can't get a browser to run. I keep getting an error message saying dpkg-query: no packages found matching bluealsa and then it says (chromium-browser-v7:786): Gtk-WARNING ** cannot open display: and then it go back to the terminal.
Is it time to start with a fresh install on a new sd card?
