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

[MaFritzlar89]

Thanks for information.
I hooked up orignal 7'' rpi touchscreen but still having issues with it.

When I enable screen in reef-pi settings nothing happens. When I try moving the brightness slider the screen itself reacts just fine but the slider is not moving. Should the reef-pi display any UI on the screen with touchscreen connected or I have to use web browser anyway?
Futhermore when I reload reef-pi and when I hit Settings tab I get
"{"error":"strconv.Atoi: parsing \"169\\n\": invalid syntax"} | HTTP 404 "

I have also problem with this screen when I attach PCa9685 board. Touch function stops working. Might be any i2c address related issue? i2cdetect -y 1 shows PCA9685 correctly. It might be also problem with power supply as I have both screen and servo board powered via RPI not a separate 5V rail.
Confirmed and solved - power supply issue.

Touchscreen itself is working just fine - showing desktop, web browser.

I can't find any specific informations about touchscreen setup anywhere in this topic.

Thank You!

Am what I reading here is that you're making hardware (?) and a driver for flow meter? :O That would be a very cool number to have on the web view for reefpi

I wish, I'm assuming this is a little more involved and needs interrupts. The driver I'm going to start with is EC, that one should be easy as the pH just needs to be duplicated and tweaked. If I can get the hang of it I will definitely try other things, the ADS1115 mentioned earlier is something I want to attempt as well.

What is the best temp probe?

These are good and last longer in saltwater than the stainless steel.

I use these


I have heat shrink and silicon on some, and flexseal coating on some others -

NOTE - only the flex sea liquid is non-toxic.. you can just get a can and dip them.. Simple and effective

Im usink this as well, but funny thing is that one I have for 2 years in and no corrosion. Its just in.. nothing around it. Seams its made of rostfrai or something..

I was just thinking of covering my temperature probes a moment ago.
I was wondering if using the 2 part epoxy for frags would conduct heat properly.
Or maybe a thin coat of silicone over the prob up the cable 6-7” would show fluctuations faster?

It's probably not needed, if you clean the probe once and a while that goes a long way. There's definitely different batches out there, some do last long, I use the metal one as well and it must be getting close to 2 years old as well and still shiny. Plus for $3-$4 it's not a big deal to change, probably cheaper than the epoxy.

I've had mixed experience with the temp probes, having bought some really cheap ones off eBay mixed with some from a local supplier. I have used "plain" and got some rust after a while. I have covered one in silicone and heatshrink. The shrinking squeezes the excess silicone and seals quite well. I think. Can't actually see what's going on inside. Another one I coated in 3 coats of the "slurry" mix some people use for ABS 3D printing (ABS offcuts and acetone). This rusted through in about a year - I suspect cracks and not properly coated.

I definitely want to give those plastic ones a try next.

I'm currently experiencing some issues getting my dashboard to work properly. It seems like the only graphs that will populate on the dashboard are the dosing plots. If I try to create a graph for lighting it automatically switches to health, it just won't let me click on the option. Also, when I create a graph to display health no graph populates the field. It just leaves an empty space.

I'm not getting any errors.

What version are you running? Sounds like a dashboard bug that was in 3.1(I think maybe, it was 3.0) and has been fixed in subsequent releases.

It wasn't working in 3.2, I updated and it's still not in working in 3.3

You need to hit "Configure" in the bottom left of the Dashboard screen. There you set the number of rows and columns and size. Then you select what you want on each graph. Major and secondary plots - so if you chose "Health", you must then click the option below and select "Current" or "Historical". Then "Update" and then "Back to Dashboard"

That's all pretty obvious, I know. But I often get to this point and find it hasn't updated, or isn't showing correctly. I find that going to another tab like "Temperature" or "ATO" and then back to the dashboard, it shows correctly.

Hope this helps.

That's not the issue. It I can change the configuration of the doser all I like, it can be 5 x 5 if I like. But if I put any health graphs in there it will be blank space. Lights simply don't click. I click lighting and it brings up health/none every time

 

[AbjectMaelstroM]

Hmm that's very strange, both my instances of Reef pi (3.2 and 3.3) are running fine.

Have you tried clearing browser cache or try another browser?

I have tried a few.

Dang, OK. Hopefully someone has some ideas.

 

[Ranjib]

Just need to get the lighting working with the Kessils. and add the dosers - dosers are all wired with the ATO on the Cat5e .. So that will be a simple addition.

awesome thank you for sharing

Those graphs that are not appearing, are those modules enabled? for example health check is enabled?
There are few UI bugs in dashboard that still left (i am discovering them in piecemeal fashion). You may have to say the layout (rows and column number) save it, and then again configure with actual elements in individual cells. Make sure all the modules (for example particular ato has to be enabled for it to be graphed) are enabled. Some elements (like lights) have limited charting support right now.

Its checked. What are the limited capabilities? Is there any reason it wouldn't graph?
