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

I'm on 2.5, but when I got settled back in after the kid's bedtime tonight, I find that it's apparently okay... huh?
I swear last night it was not okay (showing no sensors available, etc) and all day, I saw in adafruit.io there was no telemetry coming in. There's still no telemetry, but the server is showing temp data when I look directly...weird...not sure what to make of it.

.. just sending data to adafruit.io is broken or the temperature controller itself is not working?

It seemed to stop working again after about 10pm...?

No error in the logs? or in ui ? like missing sensor

Some error, but I took it resolved itself somewhere between about 24hrs ago and 4 hours ago, I'll give a look in the morning. Good thing the heater defaults to on or I'd be freaking out

Not much tonight except b inside adafruit url errors. The drop-down is apparently empty, but it was working a couple hours ago

I recall 3-4 instances, but only one was a bug that i can recall related to the current reading in UI not up to date. The missing sensor thing i could not reproduce. couple the reported ones were complicated by sensor interference due to some other device , one of the led light, one bad heater. I am thinking about what the best way to address this, susceptibility on the sensor side, but nothing from software perspective

OK. I will try replicate what happened to me and report back. I'm busy building the system, but as I recall, fist sensor added fine, second one as well. When I added the third, the first disappeared, then the second disappeared, leavingme with only the third in the dashboard.

I will delete all my tests and start over and report back.

I found a bug, when you calibrate temp in 3.0 beta it stays calibrated till you reload pi, After reloads it drops to previous initial value.

Yeah, as I suspected I think raspbian is not detecting the sensor

Temperature or ph ? What check frequency you are using ? And are you waiting till the next check period ?

hi, help need setting pH board @Michael Lane and others

I'm trying to setup Micheal Lane pH board but i got nothing at i2cdetect -y 1, as it is not showing
i tried connecting with all other sensors ans connectors on and with the pH board only connected directly to the Pi

i attached pic for the connections and results, any ideas
thanks

It's hard for me to tell from the pictures, but I think the wiring looks right.

Do you have any other i2c devices to confirm that the i2c bus is functioning properly?

Hi
I have pca9685 connected in the same way but on 3 volt and working nicely
The pic shows the connections with scl (purple) after 5 v (black) and the sda (gray) and lastly ground (white) if you want i can take other pics

In the past, Reef-Pi used to show the current temp from the sensor in the brackets circled below. I see it isn't showing. Is this something that's been removed? Will it come back?

+1 on temperature probe weirdness. There is reproducible interference (or something) when I turn on the led lights, but even with the lights disabled the temp data seems to "wobble" a lot more on 3.0, some of which are definitely not accurate readings.

Here's 2.5 (freshwater, looks correct) vs. 3.0 (reef, random spikes) charts for the day. There aren't lights or pumps or anything going off or on during this time that correspond to the spikes, so I'm kind of stumped.

oops. thats a bug .. fixed right now: https://github.com/reef-pi/reef-pi/pull/896

the strange part is whatever the cause might be, its not reef-pi induced for sure. Since all of them are happening at raspbian/linux kernel layer :-/ . reef-pi is just reading and plotting the value,, same as 2.5 to 3.0

I wanted to post here first before listing in the FS forum. I have a pair of Ocean revive lights that came off my tank today. They are reefpi ready with aviation connectors for dimming via pwm and on off relay control. PM me if you are interested.

Curious why you are selling them?

Does anyone have an idea of what type of plug and cable to use to connect my PCA9685 and my led drivers?
My PCA9685 is in a box with my rpi. My led drivers, power supply are in a separate box.
Im currently using a VGA cable but it is a bit cumbersome having a thick cable getting in the way.

I'm currently running 9 channels with LDD drivers but I will be updating my LEDs soon and will probably reduce to 6 or 7 channels.

there are 5 or 7 pin min DIN jacks, mini hdmi, micro usb ?
