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

what happens when you type

ping lightpi.local

in raspberry pi terminal and in your laptop/computer.
This is based on special type of dns, aka bonjour or multi cast based dns..its a local service discovery, and it may take a while (few minutes) for other devices in the same network to be aware of it. There are few cased where this does not work, so its definitely not a full proof thing, but most (windos, linux laptops, iphones) should work

did you rename it using raspi-config? and after rename, did you reboot the pi ?

Yes it's been rebooted, I used the desktop interface for the hostname change, does it need to be done in a terminal?

How do I stop it, just close the terminal?

press Ctl+C

your dns is working, you should be able to access it from your phone by just typing http://lightpi.local , type the whole thing

Weird, all I get is this

Weird, all I get is this

you are typing the entire address including http:// ? if not it will go in search mode.. if you type it right and dns is not working you;ll get an error message, but it will not go to search.
Do you have a build thread btw

Yes typing it all in, no build thread yet as this was to just get control of my lights while I collect parts

@LionHeart2017 Try using a browser like Chrome or Firefox on your android device. You may also want to run the Ping command from your android phone to double check that it is getting the proper DNS. I use an app called "terminal". Just fire that up and Run a Ping as you did from the PI GUI window shown earlier. From what you showed in your last screenshot it is hitting search and external DNS and not locally.


Personally I have not been a big fan of chanign the host name unless you have multiple devices with a similar setup like @Ranjib does.

This may have been brought up already but the EZO ph circuit is unavailable. Are they still making it or is there a replacement?

 

[Dave's Reef]

Any thoughts guys? This is the second time and I believe exactly a week apart.

I think its an active product - it lets me add one to my cart on their website?

Quick question: what is everyone using as their RODI container for their ATO systems?

I see its available as kit https://www.amazon.com/dp/B00798612C/ and just the circuit https://www.amazon.com/dp/B00641R1PQ/ from amazon

Do you know if anything specific going on during this time? It means the sensor readings have failed on checksum. When it happens, we can not trust the reading from the sensor. It can happen due to voltage spike or other reasons that trigger this condition. Is this transient?

How did you plumb this to the pump?

15 gallon drum that originally had chocolate syrup in it and a 30 gallon drum that originally had orange juice concentrate in it for my SW mixing.

Where did you find that!?

Craigslist actually. There is a company nearby that sells drums and container used for food goods transport. http://www.sccfl.com/container-prices.html

What do you me by transient? Like transient voltage? I'm not sure what would cause this its seems to happen in the middle of the night this is the second time it happened this time I had to reset it twice I also unplugged my Air temp and Sump temp I only run off the DT temp. The weird thing is that the sump temp notification it disabled but I was still getting text for it also? I think I'm going to try and build a new power supply right now I have a 12v that powers my relays and a 5v for the pi I just picked up a 10a 12v and some voltage regulators to rework my power supply set up.
