reef-pi is running. Can you share the config
```
cat /etc/reef-pi/config.yml
```
```
cat /etc/reef-pi/config.yml
```
OP

Configuration looks good. Are you connected to internet? How are you trying to connect to the UI? i.e. are you trying to connect from laptop or some other device, or Raspberry Pi's display itself?
Thank you?
Can you run following commands and share the output
```
ip a s
```
Shows your current ip
```
curl http://localhost:8080/api/info
```
makes a call to reef-pi , bypassing the UI
The Pi is connected to both hardwire and wifi. I'm trying to access it from my laptop using Chrome and entering the IP below sans the /24.
OP
OP
everything looks good, does the command `curl http://192.168.1.78:8080/api/info` works? you should be able to access reef pi at http://192.168.1.78:8080 or http://192.168.1.77:8080 , both address should work
OP
OP
Try running the curl command from your laptop as well as from the pi itself , if the one in pi succeeds, but the one from laptop fails that means reef-pi is working something in the networking layer is wrong (either home router doing something, or some other config in pi ), if both fails that means reef-pi is not working,

Got my temperature controller housing done today.
Now it can run permanently

I went with the two channel ssd relay for the temperature controller circuit. It will control a 50W heater and a 12v dc fan, in one of my pico tanks. Lets see how it performs, if things go bad, I'll replace the relay with an EMR version

Ranjib, you used an ac heater and a dc fan? That is confusing to me. I think it is great because I have wanted to buy a Jebao DCP pump in the future and will want to be able to turn in off and on.
Also, how do I add comments on the guides? I think we should add an section on the General Guides page that says, "What do you want to do using the Reef-Pi aquarium controller". This could contain links a specific build guide. Does that complicate things too much? Otherwise, I like the General and Build Guides.

Looks good man.
Guys, I'm cheap, so I just wanted to let you know some feedback I have with some cheap teamp probes. I'm testing out the ones linked below. The first two I tried, both of them started to rust within 24-48 hours. i decided to leave them in rusting for 5 days to verify the accuracy of the temperature reading. It perfectly tracks my neptune temperature probe always just below .5 degrees . So the 3rd one I smothered in silicon. It appears to be fine, and keeps aligned with my neptune probe perfectly over multiple days. So if you want to be cheap you could consider giving them a try too. It still might be early to give them the green light, but they seem to be doing a good job initially.

The fan acts as cooling device. I am using this:
https://www.amazon.com/dp/B01DXHFI9Y/
it has its own power adapter, with two levels. For the time being I plan to control it through the realys, but I think I can hack the power connector directly and doo a variable speed with 12 v. Since I have spare ULN2803a
. What is confusing you?Regarding website: I think it's a great idea to have an introductory section mentioning what you described. I'll definitely add this, awesome feedback. I think I'll also add how to improve the doc/website in the home page (since it lot more love).
If you are familiar with github, you can send a Pull Request directly to make changes in the website. If you just have suggestion or bug (typos, grammars etc,, I am horrible at those) you can create an "issue" in the website repo.

Cheap is best as long as it does not harm the corals. I was worried about rust, and not sure if silicone will work because I never worked with them. I made the choice before the temperature controller code was written, with little experience with ds18b20. I am planning to get a bunch of cheap probes
and run it on a control pico tanks with no livestock. I am interested in a handful of things: 1) how much temperature swing happens and how frequently the heater/fan kicks in. . 2) what the impact of fan speed and heater wattage for a given tank volume (temperature control equipment).. 3) How does LR, sand, and return pump speed impact them (environmental factors) .. this will be very interesting but long running test Thank you for the awesome suggestion.

It will be awesome if you can share how you smother them, what silicon to use, what is the process
I could use those advice

Temp controller is looking good mate, I can see your wood work is getting better as well with each one you doCheap is best as long as it does not harm the corals.

I may have missed it, but which temp probe did you end up going with? I have tried to find a "salt waterproof" DS18b20 but I have only been able to find metal ones. I also cut the temp probe off of a spare digital thermometer that I have as it had a plastic covered probe but it only has 2 wires, would that be an issue?
I was thinking worst case I could get a DS18b20 and put some heat shrink plastic tube around the probe. But I don't know how well that would waterproof it. Silicone is a good idea, and it is good to hear that it doesn't cause issues with the temp reading as that was another concern I had with heat shrink wrap and I thought it would have been even more of an issue with silicone.

Wow, that sounds great. I think I will be less confused when I get started. I will send a pull and offer help. Thanks

I went with the kanakit ds18b20 from amazon. They are bit expensive (13 $ for 1 probe) than bare steel ones.Temp controller is looking good mate, I can see your wood work is getting better as well with each one you do

if you are silicone coating, this is good too: https://www.amazon.com/dp/B06XW6STL7 , 3.5 mm connector attached already
