What is everyone using for a PH board? I looked on tindie and the ML board is out of stock. The EZO is unavailable. Is there a newer better board out there?

I have ML's board and Rob's from RoboTank. Both work great.

Thanksgiving is approaching, and i am thinking about 4.0 release. It has been very hectic and i have not been able to push a lot of code as expected, lately. I am thinking whether to do a 4.0 release or skip it. Technically we dont have to have a major version release, since there no breaking changes. But historically it has been a tradition to do yearly reef-pi release during thanksgiving, hence the dilemma.

I am thinking of wrapping up some minor bugs and polish documentation and cut a release (4.0 ?) , if we want stick to the tradition. We did have quiet a few changes across the board (new features, drivers, bug fixes etc) encompassing 3->4 development, but most of those have been already incrementally shipped.

Let me know what you all think

I think you've done an amazing job, based on version number, 3.5 seems to be stable so maybe a good point to start 4.0. The minor issues are known and can be worked around so no need for a quick update, enjoy the holiday or play in the code. :)

Seems like what i need is basically this circuit posted by @robsworld78 using the LM358D? I'd just hardwire it to the config i'd want for 10V out, put 3.3V PWM from the RPI in and get 0-10V analog out to feed into my gyre controller?

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

Hi, so I wanted to introduce myself to everyone, I’m Rob and I love aquarium controllers. :) About 5 years ago I started building a controller of my own Robo-Tank, it’s pretty cool but expensive for a few reasons, limited web access and the display ran on an Arduino so it was slow to load like...

Yeah that circuit will put out a 0-10v analog signal so just need a few components.

I wouldn't mention it but as you can't find I do have some.

I have ML's board and Ron's from RoboTank. Both work great.

Glad it's working out and BTW it's Rob but hey 2 out 3 letters isn't that bad. :)

Hahaha yeah, fat fingers got me on the phone. Edited.

The EZO is available direct. Not on Amazon. I am looking at it as we speak and about to order one.

Getting started with my build, already tested and working. Doing power relays today and waiting on PH board to get here. Looking forward to getting it all together.

Does anyone know the positives and negative going with the ezo board vs one of the prebuilt ones?

ezo is a minimum of board and carrier board which is atleast $55. With the pre-built ones you support a follow member and don't have to deal with the ezo crapping out on you after a few months.

Not entirely correct, you don't need the carrier board to hook up the EZO, however it makes it easier. I looked at a pre-buit but I couldn't find any in stock. Anyone have any or know of any in stock?

At the very least you need a BNC, socket connectors (or risk voiding warranty) and resistors to make your own.

Pro: three point calibration , ability to use with i2c or uart, support for temperature compensation etc.
Cons: double the price (including the carrier board)

Any chance anyone has a reef-pi image? I am not infront of my system away from home. My wife just told me the tank lights did not come on today. It appears the memory card has failed, starts to boot and then crashes. There is no way I will be able to walk her through a normal installation, but possibly image a card. Tank temp is down to 72, I had her move the heater over but I would really like to get this controller back running for ATO, lights etc. Thanks for direction

For situations just like this, I have a spare card in my cabinet set up just the same way as my main card. In the case of a failure, the replacement card is right there and I just need to swap them out and can be running again in 5 minutes. I learned the value of this the hard way.

I am recently tinkering with Raspberry Pi and SATA drivers. It is now relatively easy to just hook up a USB3-> mSATA/SATA3 adapter then use off the shelf mSATA/SATA3 drivers. The total setup should cost less than 40-50 USD and you'll have a 120G SSD thats much more durable. There will be some configuration work (pi will still boot from sd card, but reef-pi can be configured to keep its database on ssd), but i think this solves the sd card issue significantly.

My pi is acting weird, one doser switched on at the desired time but didn't switch off, thankfully I was sitting there inspecting the doser at the time, that was last night, today it's working fine.

Then just now I initiated my 10 minutes feed macro which switched off the desired items, but didn't switch back on. I've just done a power off and on and it's working again.

So what I would like to do, as I do feel my sdcard is corrupted is set up a spare card(I did buy one for that purpose but ended.up in my daughters tab) is it possible to set it up on a different pi and then transfer it to my reef pi? I have a pi4 that I use for audio and my reef pi is a pi3 a+

yes. it should be possible.
Install the same version of reef-pi if possible on the new pi and just copy the db over. you should be able to dry run by turning on reef-pi on the new pi, without any thing attached (as long as you are not using wireless drivers).

I'll be doing a headless install, hopefully that won't be a problem?

Still long way to go till old glory is restored , tanks are humming along. Got most of algae under control. Hopefully once the new house chores settled I’ll be able to focus more

You'll get the error because the pump is disabled and the dashboard is set to display the pump data, which it can't as there is no data being read. Do with s temperature sensor and you'll also get an error. If you are not using the pump then remove it from the dashboard.

please advise which PCB board is most feature rich that I should look at? there is a ROBO TANK. Leviathan .
any others one can buy ?
