Reef-pi 3.0 alpha 2 loaded and configured to give it a run.

So far so good, temps sensors, light pwm, equipment all working. Ph board configured and reading -32768 when no probe connected and with the probe pin shorted out reading close to 0. Yay! The phboard @Jonathan Troutt built for me works....

Now to order a ph probe, any suggestions?

Thats awesome man im glad to hear its working.

@Ranjib i have the dual float sensors for my auto top off. Is there a way to still have reefpi control my autotop pump? Basically turn on pump bit if pump stays on for too long to shut off?

 

[Bigtrout]

Are your dual sensors connected to reef pi now?

What type of sensors? Voltage?

What type of pump? Voltage?

Im thinking a great setup would be one sensor into reef pi, reef pi controlling your ATO.

Second sensor wired inline with your pump as a failsafe...if first sensor or reef pi messes up, the second sensor breaks the voltage going to the pump.

What's the best way to upgrade to the alpha release of 3.0? Will any data be lost? Can I easily roll back to 2.3 if needed?

 

[Bigtrout]

3.0 cant use the 2.3 database.

You have to purge 2.3 completely and redo your setup in 3.0, but if you save your 2.3 database then you could always go back easily.

That all being said, 3.0 has been stable for me so far, and im awaiting a ph probe to arrive.

I have noticed one big improvement in 3.0, my adafruit i/o feeds have been much more stable. With 2.3 and 2.4 i would get the occasional feed "drops" for a moment of two here and there, with 3.0 it has not dropped a feed yet.

What file(s) contain the 2.3 database? I might write a python script to convert when I get 3.0 up. This would make the upgrade a lot easier for folks.

Hey all. It's been a while. Just to update, my reef-pi had been running good then we had a few power events and I had to shut down via power pull to resolve a clogged drain because I couldn't access the system. Raspbian corrupted or something and i had zero boot activity. No activity light or anything. Kinda sucked. Reimaged the SD with a new version of raspbian and reloaded latest stable so I'm back up now thankfully. It's nice having a chart as to what is what. One of these days I'll get smart and make a SD clone.

I have power outtages and net outtages alot. To avoid raspbian corruption from timekeeping issues, i added a ds3231 real time clock. That addition has kept me up and running thru once or twice a week power interruptions since January

Let us know if you need help with anything

@Ranjib is having an input to trigger a macro something thats in the works?
Having a physical button to trigger my feed fish macro which turns off my pumps for 4 minutes would be sweet, so the wife unit could feed the fish without having to get on the UI ;)

This is wife unit 2.0 and I dont plan on doing an upgrade there...lol

/var/lib/reef-pi/reef-pi.db

Thats the database file

@Ranjib - do you have a DB schema anywhere available? I'd like to write a converter...

I'd like to see this feature as well and I've started working on it from time to time (partly as an excuse to understand chardev gpio). I'm porting libgpiod to go so we'll be able to use interrupts instead of polling to get the button changes. My day job has been insane lately, so it's slow going. I'm hoping to have it implemented in v3.0.

Thanks, if you can post a guide of how, i will be happy [emoji2]

Same here :)

I see the option for the pico-board driver...what 'address' do I use (and if it's not the default, how do I find it)?

Also, can it be used for inlets, outlets, etc?

sudo i2cdetect -y 1
adress is a hexadecimal, convert to decimal and use in reef-pi


example:

pi@raspberrypi:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- 48 -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
70: -- -- -- -- -- 75 -- --


48hex = 72dec

@Ranjib - wrt the database, what's the format for it? obviously there are ASCII elements in the file,but it is binary mostly. Is it just a packed binary file of some sort, or is there a db reader that i can invoke to make a converter?

 

[dmolavi]

Possible issue with alpha 2....I updated the temp chart with a new min/max, restarted reef-pi, but the change hasn't kicked in...

It’s boltdb, an embedded database written in golang. It’s key value pair based, unlike relational database. All reef-pi data is serialized as json and stored there. It’s trivial to read/write it from other programs. Every key module (ato, temperature etc) as bucket (equivalent to tables in MySQL) and relevant entities are stored inside the relevant buckets
