So looking at the spec for the p30n06le i.e 30A 60V would you be able to run a full bank of LED's from it that had a draw from 20 x 3v 3w led's in series ?

yeah, but you'll need heatsink (and fan probably), also they'll be not be independently dimmable.

Well, it ain't pretty, but I think it might just work... for now until Amazon gets that SRP8 back in.

I'm using the RJ45's for Temp, and ATO input.

This is such an awesome project @Ranjib , Thanks for all your hard work!!!

I am assuming this is powered by a 8-channel relay internally ?

Looks so much better than my scratch builds

. Good job

Hi to all,some good news this is a beauty just some little hick up. Where is the max temp adjustment?

:-( , thats a bad UI bug. Let me fix that asap.

Sorry about that.

I wanna see whats inside.........I wanna see whats in side.. I wanna see what is inside I want to see .. Ohh wait.. just show the inside already..

Sheesh ..

Please ..

@janos released a new beta with fixes

reef-pi 2.0.0-beta-5
Changes:
- Fix temperature control (max value) UI
- Fix redundant api errors in configuration tab
- API error will have better error message in UI
- Allow setting custom RPI pwm frequency
- Allow enabling pprof (for performance profiling) via UI

Release builds can be found in usual place: https://github.com/reef-pi/reef-pi/releases/tag/2.0.0-beta-5

Upgrade should be simple as:

Code:

wget -c https://github.com/reef-pi/reef-pi/releases/download/2.0.0-beta-5/reef-pi-2.0.0-beta-5-pi0.deb
dpkg -i reef-pi-2.0.0-beta-5-pi0.deb

Just a quick question to the electronics gurus, on the temperature circuit, how important is the value of the 4.7k resistor? The closest thing I have is a 5.1k, does this throw the calibration off?

Should work fine

Thank you Ranjib you are unbelievable,never see that kind of help anywhere.Go download right now.Thank you again.

Ok, good. Then regarding calibration, I checked the probe/reef-pi to a known good thermometer and it fluctuated between 2.5 and 3 deg cooler. Is there a way to calibrate reef-pi, or is it just the way it is?

We don’t have any calibration module (I intend to add one , there’s already issue tracking that) .
That’s odd though , ds18b20 should always be accurate within 0.5 degree Celsius. The resistor should be ok till 10k :-/

I’ll do a round of testing soon and verify it

Hi to all again,and big thank you for Ranjib,this is what i was dreaming about.No hick up no problem at all.To me that controller is wort more than the best Profilux, because i made my self.(with Ranjib and Erika)
Look that picture,perfect or what?

That is odd.. I have 4 temp probes , One is next to a high end temp-humidity thing, One is outside the window (yes just to make sure its tracking separate from the others ) One is in a Hvac floor register, and One is actually on top the heat sink on my pi zero..

temp probe next to Known good probe near perfect... on fireplace
temp probe in ac duct shows 55 deg when ac is running and slowly moves up once its off. its high temp is about a deg lower the then temp probe on the fireplace
temp prob outside the window . Well it depends on where the sun is.. But it does kinda follow local weather app. ( i assume its accurate ) Mid day today 109 .. GRRR .
The probe on the pi heat sink runs at 100.5 to 110.00 If i boot the pie into ui it will jump to 125. So i assume its working well..

The pi zero booted to desktop might as well be brick when it comes to usability .well thou its not heavy enough o break anything so less useful then a brick .

Some of these probes are on very long cat3 wires .. See post above Somewhere ....

Sorry, didn't mean to throw a wrench in the works.

Yep, it's ugly inside, but it's working.. finally. I took apart an old wall wart I had for the 5v power to the Relay, but I must have soldered it wrong cause it blew the fuse when I plugged it in. So off in search of another power supply to power the relay.

Yeah,don’t go GUI /desktop with pi zero. It’s only for text mode
