Your sensor is not being detected. Check wiring and make sure the sensor is wired correctly or not shorted.

Thanks for that, fixed

Following this with great interest..need something to fill the time when i'm off work for 11 days over the holidays :)

quick question - i use a BuildMyLED and ReefBrite LED on my tank. Would ReefPi be able to control the dimming, etc on these? Otherwise, I just temp/pH monitoring (not control) and pump control (jebao rw4)...

@Ryan115 has done something on this line, this was his original post: https://www.reef2reef.com/threads/r...-on-raspberry-pi.289256/page-317#post-5170928

It is recommended to not use more than 20ma from individual GPIO. There are few leds that draw less than 5ma, you can use those.

I did some googling. Looks like 25mA per pin totaling 400mA. Time to look around.

I have a manual dimmer for the BuildMyLED fixture, and ReefBrite has one available too. How would I go about figuring out what each needs for dimming, etc? Sorry for the newb question...new to the pi scene...

Start with posting picture of your light and specifically the control signal/adapter part, once we deduce what type of control signal it expects (voltage and current ) rest is easy

I know for sure there are some through hole 3.6 mm led that consumes 2-5 ma current

Ok. Cool. Can you link me?

Most of the panel mount LEDs draw <20mA.
If you want lower/dimmer just add higher limiting resistor

Or you can always get mounting sleeves for regular LEDs

Another one that will be joining the Pi controller club. I've just ordered a Pi Zero W. I'm planning on reading the thread cover to cover but are there any particular post#'s I need to pay attention too?

Welcome! It’s probably best to start with the guides then post when you have questions. I found it easiest to search the thread when looking for info rather than trying to read the whole thing.

Will do that then, thanks.

I second what b4tn says. Also do a site search in R2R for reef-pi. In addition to this thread, there are quite a few individual build threads for the reef-pi and they may give you some inspiration for your own build.

Here are my fixtures. The BuildMyLED is on the left and has the silver driver module.
The reefbrite dimmer is http://www.reefbrite.com/product/in-line-dimmer/

I just ordered these for float switch’s and temp probes. They have several different pin counts. I ordered 2, three pin and 2, two pin connectors.

LOL, I was going to do the same thing with dimming tree lights on a timer but my wife said no.

We had to do it since our light and wall outlet is blocked by the tree, hence wife agrees :-) . To her point this blocks my electronics shelf as well during the holidays , so more time for family :-)
