Hmm ok . Still getting a blank screen when I run start-dev and go to the main page...

Lets take this to slack channel

Set to 78, gap of 1. They are old from an aquaculture project circa 2009-10, no 0-10V outputs.

Whoa! That kind of shoots the "replace heater every year" theory! ;Wideyed

Comments on the heater Discussion. If your Heater Recommendation is 200w use two 100 or 150 w heaters Each on there own controller or controller channel.The likely hood of having two fail at the same time is very low and if one fails your still going to keep the tank heated . I have 4 500w heaters on my tank connected to reef-pi and Ink-Bird controllers .The REEF-PI Controlled outlets are normally open , So if the pi fails the heaters will still be on the Ink Bird controller

I run mine the opposite way because aqueon pros are solid state, not bimetal strips. My heaters control temp, and reef pi is set a degree higher in case the heater control goes haywire. Plus with aqueons being electronic control, switching on and off alot probably isnt good for them

I also run Aqueon Pros, they are not fail proof but so far they have done there and compared to the others I think they are better, I think they are assembled in Italy. They have a newer version now, not sure what they changed internally but they do not appear to be quite the same. I do not have the reef-pi controlling them quite yet but my plan is to run them in the same manner, reef-pi will be the fail safe if the temp goes to high.

I have to update the developer documentation. it should not use ranjib/reef-pi , that was before 1.0 .

Well that would explain it, I am willing to help out with that kind of stuff just let me know what it should be and I will gladly update.

I was pretty tired when I was doing things last night and thought it was just something I was doing.

I am working on adding a new type of connector to represent analog inputs , like the ones used for ph, orp, salinity etc, and I am thinking what to call them. We have outlet representing digital output, inlet representing digital input , jack representing variable dc output,,, any suggestion for the new connector name that will represent analog input ?

Ranco are industrial temperature controllers, they have been making the same thing reliably for a long time. The only failures I have seen were due to being exposed to salt water spray, or thermal issues. Otherwise I have never seen one fail. They are not your normal bi-metal strip situation like home aquarium oriented heaters.

Honestly, I find all of that confusing. I would have named them what you are describing them as (digital output, digital input, PWM output, analog input). Once I figured it out, no big deal but it was confusing trying to figure out a jack vs an outlet, etc.

@Tom Bishop which document you are following? I am not able to spot anything that reference ranjib/reef-pi, I am looking at this: https://reef-pi.github.io/additional-documentation/development/

I was following this guide - https://reef-pi.github.io/general-guides/development/

Here is the screenshot of the section:

I assume I should follow the one you listed above?

Weird, mine shows something completely different at that URL:

I guess Anal-IN is not under consideration

But maybe name them what they are and call them all connectors.

DI=Digital Input
DO=Digital Output
AI=Analog Input
AO=Analog Output
PWM=PWM Output

May simplify things in the future, with reef pi expanding into different things.

Nice and simple.

It will be nice to be able to attach different modules to an analog input as well, for example temperature probes in addition to pH. It requires different analog front end circuitry, but from a digital perspective is just analog input, with a different conversion function.

Yup . We have to convert the ds18b20 code as driver for that

I don’t know how I feel about that, but I guess with tank of that size it’s ok. No QT?

@Ranjib my biggest fear is a runaway doser. I have been dosing from one bottle to the other for about a week now with no issue and officially moved over to dosing my reef last night. But it’s still in the back of my mind that a glitch will dump a bottle of alk in my tank. Any plans to put alerts and maybe an auto disable on the alert similar to what you are doing with the ATO?
