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

[Bigtrout]

I recently got a Raspberry pi 3, i downloaded reefpi. It says is active but the browser doesn’t open. Or i can not find it anywhere to open it. Any ideas?

It may be helpful to look at what IP address its getting on your local network. You may be able to find this on your router web ui, or perhaps an app to see what address it is getting.

You could try Angry IP Scanner it will show you what is your IP for raspberry pi .

I use Fing https://apps.apple.com/us/app/fing-network-scanner/id430921107 on my iPhone to see what my Reef-Pi ip address is

I use google wifi and it has a nice mobile app that lets me see which devices are connected, there IP etc. I also get to open port and access individual reef-pi dashboards directly if needed.

Id use google wife but Alexa's voice is so much sexier o_O

oops :-) , dang typo . I'm gonna edit that before its becomes more embarassing :-)

Ability to trigger macros from timers just landed in 3.0...

Awesome!

Been testing out the Kasa hs300 powerstrip for few days in my garge tank (test tank). Its been working mostly, all the outlet controls (equipment on/off) are working as expected, the current monitoring bits are also working mostly but i see occassional failure in network communications, but it mostly benign and at worst will cause few missing data points in the chart. I am seeing sometime the tplink driver is failing to register during reload, which is something I have to take a look at. . I suspect this due to the network or boot sequence (reef-pi trying to connect the hs300 device before network is up etc.

Here is a screen shot of the setup, note, all current monitoring is modeled as ph sensor

I think the usage is measured in miliamps, plug5, bottom right corner is running heater and I can see the usage spiking to 240 everytime it turns on. The controller (reef-pi) itself is drawing 24 miliamps. This build is power by a 12V 3A power adapter and circuit involves a pi zero, one temp sensor, one fload switch, one kessil control (two lm2596) and an hs300 powerstrip. I'll try to post a photo of the test tank soon.
Overall, I think the tplink driver is usable, but could use some more hardening.

This is fantastic news. I have an extra pi zero laying around, maybe I need to get an HS300 to play around with. If this becomes reliable its an easy way for people to get a working reef pi without messing around with mains voltages.

OKAY SO I LEAVE TOMORROW TO GO OUT OF TOWN AND I NEED THIS CONTROLLER WORKING TO HELP MY WIFE WHILE IM GONE WITH THE TANK. SO I HAVE THE RASPBERRY PI ZERO W with the ML Hat and i have a new ADJ SRP8 outlet when i turn the outlets on and off on the reef-pi screen the lights on the HAT turn on and off so i think that part is setup correctly. im assuming either the wiring is wrong on the serial or i messed up elsewhere or a setting maybe? any ideas?

Do you have a thread where I can check how is your setup ?

yeah let me update everything and ill send it

Hey everyone starting a reef pi build

looks ok to me. double check the uln2803 direction, its not very clear from the image. Given you are soldering the IC directly on the permaproto board, fixing any mistake will be lot of work Nothing appears to be touching there I made a mistake and got impatient my nice soldering stuff is at...

Hi Ranjib what the fq rate are you controlling your kessil light at. I only need 3 pwm control device so getting a 16 channels ic seems waste of room. So I try to figure if I can run the kessil with software pwm. As of now I'm running at 100hz but it not quite stable.

320 hz and intensity can only be dimmed till 13. Below that it starts to Flickr. I have also noticed if the circuit involves other sensors/components , you may have to add extra passives.

Hey guys,

Has anyone tested the accuracy of the ds18b20 temperature probe? I just got it hooked it up to reef-pi and I'm getting a steady temperature of 76.6F. I have a cheapo digital temperature probe that I've been using for a few months now that is currently reading 79.0.

Discrepancy of 2.4F

Not really sure which one is accurate.

I had a calibrated temp probe controller that i used to control heaters before reef pi, i tested the ds18b20 DROK probes against it and my 4 ds18b20 were all within .2 degrees of the calibrated probe, and all within .1 degrees of each other.

If you have doubts. Make an ice water bath, see how close each of them read to 32f.

Just looked up the ice bath technique. Will try that with both of them tomorrow. Thanks!

I think a feature of reef pi 3.0 is the ability to calibrate the temp sensors but @Ranjib could elaborate better on that.
