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

[Ranjib]

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 is an AI and API gateway that securely routes, transforms, and observes traffic to services running anywhere—powering APIs, AI agents, and LLM workloads.

You can use ngrok out of band (i.e you have to set it up by yourself) with reef-pi but nothing I am aware of that makes it work straight from reef-pi. reef-pi is way smaller in terms of features compared to octopi. Gina (octopi author) is a gifted programmer who dedicated his full-time work on octoprint. Its an amazing piece of software and one of the inspirations for reef-pi. reef-pi does not have the plugin like design that octopirnt has. One day..... :-)

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.

I was confused what pritning had to do with anything when googling - makes sense :)

Sorry for the confusion. I will have to play with it some more. I was having issues installing it on my reefpi. I discovered ngrok while I was installing octopi for my printer.

No harm, sounds like a good baseline Raspbian install. Also, totally in favor of using ngrok, and its a very good callout :)

Hello Reef-Pi folks,
I am running Reef-Pi 4.0 on a Robo-tank board and I am having trouble with my temp sensors. I have 5V at the 5V pin, and 3.25V at the Data pin on all temp sensors, but when I connect a sensor it is not detected? When I go to the temperature page and try to add a new temp sensor nothing is available under sensors. I have tried 3 different kinds of sensors, all of which I have seen work on other setups. Any suggestions?

Thanks

I haven't gotten to this part yet, but my understanding is for the temp sensors, there is ground, power (3 or 5 volt), and a data gpio. 2 power cables would have no data pin to send the temp to.

Sorry if I was unclear. I have a three wire sensor, with ground , 5V, and data. And when I put a meter on my board pins, I Have 5V on the 5V pin, 3.25V on the data pin (expected as I understand it) and then the ground pin. I use this to verify that my soldering is good and that the board is operating correctly. I am trying to get it to recognize a sensor but nothing is showing up?

If you swap the 3v to gpio 17 or any of the gpio pins per the mapping below, it should work. The open gpio pins (non power/ground) are for sending data.

Is one wire enabled?

yes it is.

thanks

I am using a Robotank hat for my Reef-Pi so the GPIO wiring happens in the circuit board. Thanks for the suggestion.

 

[Sarlindescent]

Cool, I'm out of ideas. Good luck.

Standard gpio pin for the temp sensor is gpio 4. If you want to use an other pin that is possible only you will need to update a file in rasbian os. If you Google it you will find it.

@Ranjib and the other contributors, instead of complaining about yet another problem, for a change I just want to say that all the work you do here is appreciated and a great help controlling tanks.

Hi, sorry to hear, were you able to get it working? If you still have problems send me an email or DM.

Slight update on my build. Still waiting on USPS to deliver the last item so I can hook up the ph probes... built a custom wire harness to clean things up and a power and ground distribution hub (picture was before I fixed a couple solders). Also for the ds18b20 probes, the wires were 28 guage. Most common wire strippers don't go that low.

Before harness

After

Additionally, I am looking for usb powerbank with a pass through to act as a UPS. Any recommendations? If not, the wire harness was designed to free up the pins for a pre-built pi UPS.

Is there a reason i cant set timers > 60 minutes? My fuge light auto has a timer built in, but it resets if the power turns off...so i just want to control its on/off via ReefPi and turning the outlet off at 7am and on at 7pm but i cant? Is there another way other than timers?

Thank you so much for the kind words. This means a lot to us. Your support and enthusiasm is what keeps the project going :-)

Ds18b20 is 3.3v based, not 5v

Are you using ds18b20 sensor ? Can you share some pics and configuration details ? Check dmesg output for any errors that Linux kernel might be showing, they should have words “one wire “ or “w1”
