That looks great, I will upgrade this weekend and start testing it out.
One comment to begin with, it looks as though the temperature and the heater/cooler tabs are somewhat redundant, and the 0-100 scale for temp seems as it will smooth out any moderate changes, can that range be changed?.
The works you put into this is astounding. Thank you!

absolutely, i'll add it in my todo list for next release

temperature chart shows only last few hours trend at minute level granularity. heater/cooler shows temperature at 1 hour granularity for last 24 hours, along side heater and cooler usage per hour.

Question: Whats should be the YAxis temperature range should be? Min/Max? or a specific range , like 70->80?

Question: Whats should be the YAxis temperature range should be? Min/Max? or a specific range , like 70->80?

I can see it working either way. Min/max gets up close and magnifies your small scale variability, 70/80 gets you overall trend, which is probably more important.

Got it.

I am thinking of making the minutely chart min/max and the heater-cooler chart 70/80.
We can change the chart types as well... reef-pi uses rechart for charting , some examples of it can be found here

 

[Somnifac]

I would say that a min of 70 and a max of either 85 or 90 would be best. While 80 is getting above what I would want to have in my tank, it is not uncommon for it to briefly reach those temperatures in warmer climates.. A max of 80 would clip that off.

Hmm, OK just upgraded and what I get is a mostly blank page that has a header saying "Reef-Pi" a divider line and one blank navigation tab. I've purged 0.7 and the database twice, still get the same page. I'm sure I've screwed something up as I'm not a Linux guy.

I've run into that when it was a cache issue. Usually a forced refresh will fix it. To really check if it's a cache issue, open an anonymous\incognito (whatever your browser calls is) and attempt to load the page.

Ding, Ding, Ding, you when the prize. The login page comes up when in "incognito". Cache issue with the login page. Thanks!

Edit: The issue is all on my side I know, but now I can login but then it goes back to the blank page unless I'm "incognito". Something that has changed is not playing well with my chrome settings.

Can i upgrade from .3 without changing any of my pins on the gpio?

Most likely not :0(
You have to delete the old data base and start afresh, the underlying data model has changed..

Have a quick question. I built the lighting circuit as described in the docs. Is there a way of testing the output prior to hooking up one of my Kessils? I tried measuring the voltage at the output but I'm not sure if that's right as I get the same 12v out no matter where I adjust the Reef-Pi slider to. Also, When I hit "update" I do not get any real confirmation that anything happened. Is that correct? I so glad you are a patient bunch!

Then its not working as expected.
You should always test it before hooking up. What equipment you are using ? Multimeter? Can you share your reef-pi settings? i.e. dev_mode is disabled, what pins in jack, wiring, etc.. a pic will be helpful as well

What mode you are using to setup the lighting ? manual or auto? Test the circuit in manual mode.

Yeah, testing with a multimeter. Pretty much followed your docs to the letter. Created "jack" j1 assigned it pins 0,1. Under lighting created a control assigned it to j1. Two sliders appeared, set them to "reverse". Unchecked "dev". Updated and rebooted several times. Light widget shows up on the dashboard. I've tried to take a photo of the breadboard, not sure if it will help. The only thing I wasn't to sure of was the resister values as they are not marked on the diagram, searching the internet I believed that the 1ok went to the base of the transistor.

Awesome.Can you check your transistor wiring? Collector will be hooked to power, i.e. 12v and emitter to ground, base to pwm input. I think you have reversed it.
Also, check the pca9685 directly first, to ensure its indeed generating 0-5v output (or reverse), that way , you can know for sure if the issue if from pca9685 chip or the transistor circuit

Checked the PWM, no matter where I set the sliders, I get 1.5-2v is all. I looked at the transistor several times unless I'm just stupid! Let me run it past you, looking at the flat of the the transistor, emitter is on the left, correct?

[philshel]

@marspeed , thanks but it's a bit to small to read. I found similar schematics (at least what i can see) and believe I have it correct?

Hang on. If the PCA9685 output itself is not working, then there is no point testing the transistor. Lets ensure that pca9685 board is generating 5v pwm as expected.
Can you share your reef-pi log, when you change the channel intensity ?
