Nice :-) , share a screenshot of your garafana or prom dashboard if you can :-) I love to see those . With Prometheus and grafana on board , you can now have arbitrary metrics retention, any types of graphs , extremely customizable dashboards and alerting capabilities. I’m glad you got it setup

I haven't installed grafana yet, although prometheus has a graph, it looks great

grafana its ready, i love this. thanks @Ranjib

Some updates one the 3.0 feature developments. I am working on adding equipment control via the ph probes, similar to the temperature controller. Folks who want to control calcium reactor or co2 injection would be able to use this feature. Next, I'm adding the ability to trigger macros from timers modules. I expect the backend work to wrap up by next week (core controller logic, after which I can test things using API), and then proceed to the frontend (UI) work.
In parallel to this the pwm profile work is also progressing slowly. Light module in 3.0 is already integrated with the new PWM profile code. This will allow us doing lunar, storm and other types of simulation. In general, adding new PWM profile will become easier (similar to what HAL did for devices).
I'll post images soon as I am able to test out these features (UI or actual setups).

Curious question. I'm looking at some driver options for my LED's. I have a few nice 32v 19A power supplies and was looking at these really inexpensive drivers.



They come in a 700ma version also.

Not sure if the "150KHz fixed frequency PWM Buck" is a concern?

Was wondering if the reef-pi/pca9685 would be able to control the pwm on these, and if so what would the circuit look like? Would it be...

Power Supply to Driver V+ V-
pca9685 Pin to Driver PWM V+
Driver PWM V- to Reef-Pi Ground
Driver LED V+/V- to LED String V+/V-

Yes, it will work. I tested it before. now problem u can use this.
and u can also try this also http://www.veltisti.com/dcdc-led-la...rt-circuit-protection-module-12v28v-p-56.html
this is much cheaper than yours ...

Good news, thanks. Any idea how I'd hook up the pwm and reef-pi setting for one of these?

Just talked with local electronics parts store guy. He has some of these he was playing with. He said they work, but hasn't tried the pwm or obviously never with reef'pi. I'm going to go grab a couple to test out...will report back how well they work.

Hi to all,just need to tell thank you to Ranjib for that wonderful Reef-pi and Michael Lane for the V2 board,what makes my life 100 times easier.Some pics from my box.

Sleek, clean and beautifully done!

Thank you crusso1993,that is my second box the first one was just basic running 2 year long without a hick up now i got a beautiful hat from Michael Lane and that is my second build.Happy with the outcome. PH was big part of the second build.

Very cool!
I originally joined R2R for a number of reasons. One of the biggest reasons was because I wanted to build a control system for a big tank I was going to be starting. I got pretty involved on this thread and a number of other people's build threads. Long story = short story = life happened and my plans were majorly changed. I never built the big tank or controller. I still have the old Antec computer case, various parts bought and things waiting. Since that time, I've always followed and been mildly involved in this thread. The improvements made by @Ranjib and others, just since the end of last year, have been outstanding. I'm unsure when I'll actually be able to start moving forward with everything because, well, life throws curve balls and sliders sometimes but I always enjoy others sharing their reef pi builds! Thanks for sharing yours and sorry about the short novel here!

Which one of these is the right setup lol

Awesome :-) . Congrats on finishing the build and thank you for the kind words, what a great way to start my day :-)

They are different image, but both have the same circuit/connections

 

[youngblood421]

So either will work then?


Also is there a diagram to connect it to the serial cable

well....tried to get the 700ma version of driver working. It's driving a string of 10 3w LED's just fine, but for some reason I can't get the PWM to work. It's either always on or always off depending on the wiring configuration, not sure what's going on. I've tried all worts of wiring combinations, and all sorts of reef-pi settings. Will have to test more later. Anyone have any idea's why this may be the case?

Is there a way to test if the PCA9685 PWM is working properly?

 

[bala murugan 00500]

it is simple .. here I'm drawn one simple drawing

in reef pi first, u have to enable the PCA9685 option.

after that, you have to add pin number (pin you connecter in PCA9685) in configuration > connection > Jacks.
after that reload the reef pi .

then under the light option, you have to create by clicking +. ... then u can assign separate led control over there

I'm not an experienced person in feer pi and in electric .. just sharing what I know and what I tried and work
if I'm wrong, please correct me

Awesom thanks for detailed reply. Yeah looks pretty much what I tried. only difference is my setup has the pi 3.3 going to the vcc not the v+ of the PCA9685....maybe I'll try that. Maybe another PCA9685 and another driver.....perhaps mines broken. I also might have to find my old oscilloscope to see if the pwm is working.

At a loss atm :/
