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

yup, the graph does not update automatically .. i'll note down this, and get it fixed in the next release, thanks for pointing it out.
What problem you are facing with adafruit.io ?
- Have you enabled telemetry and provided adafruit.io key under the system tab?
- Have you created a feed named "temperature" in adafruit.io website?
- What does reef-pi log says? Can you share it?

Not a problem that the graph doesn't auto update. I was sure I had done something wrong. BTW, the graph is great!

Yes, I enabled telemetry
Yes, I entered the key in the Token text field
Yes, I created a feed named temperature in adafruit.io

My monitor and keyboard are not connected to the pi, I am viewing reef-pi via wifi and can't ssh or use screen - probably due to ignorance.
I will try to get the log tomorrow evening.

Thanks Ranjib.

The 5V relays used on this board are drawing a fair bit more. Mine are HK3FF-DC5V-SHG. The other one that seems pretty common, SRD-05VDC-SL also specs out around 70mA. I think 20-30mA may be more common for 12v relays.

I tested mine out with a 1 ohm resistor on the 5v line.
0-relays on - 3.1 mA
1-relay on - 70.3 mA
2-relays on - 132 mA

Currently I cannot activate more than 2 relays at a time, even though the DC supply is rated at 700mA.
I am going to buck down my 12V 150W supply for further testing.

I had very similar issue, first I had lower ma, relay lights would come on, but won't switch on, and I didn't hear the mechanical click sound either. then I went with 700ma, had only 2 relays turning, now I have 1.2A I believe and it works for me.

I have not been connecting to mine directly since it was first set up, I can help walk you through it.
ssh should be easiest, I recommend PUTTY http://www.putty.org/
When it opens, you just need to enter your pi's IP address, mine is 192.168.0.106. Be sure it is set to SSH

Once you hit open, it should come up and ask for user name, default is pi.
Then it should ask for password, default is raspberry.

That should be it.

Sounds like the same that I am getting.
I cant make sense of this though.

me neither, I experimented with whatever old chargers I had at home to get it to working.

That's pretty much where I am...digging through the big box of old chargers. Found some from my old Nokia 6110.

Thanks for helping. Ryan, I am in using Putty. what is the path to logs

those good old days of Nokia indestructive phones!

sudo journalctl -fu reef-pi.service

I did a grep | reef-pi and got this

I dont think telemetry works while in dev mode, though I could be mistaken on that.

thanks Ryan. Sorry I have to log off tonight. Thanks Guys.

 

[Ryan115]

disregard...

 

[Cary]

Yep, I made sure I was not in dev mode. thanks

the user for telemetry should be your username for io.adafruit.com, same place you get token/AIO key

 

[Cary]

What field in the system tab should my user name go in?

 

[Cary]

Sorry, I should have looked. I entered by user name in the system tab below the key.

Reload reef pi from system tab, if you have not done it already

This is an important learning, worth capturing in faq

Okay I been looking at the videos and readding. I have a couple of questions.

• for the 5v male power socket can you use a smaller power connection? For example a laptop type of supply?
• with the rasberry pi zero W and 16 channel is it possible?
• For the Leviton adapters they come in two inputs are each input controllable or only the set is controllable?
