Previously, when a Macro was running, the "run" box would change to "running" showing you a macro was running. Is there any other way to show easily a Macro is running? Not possibly some chance of a "widget" type thing on the Dashboard sometime in the future?

I think my temp issue is a general i2c issue. It works for a variable number of minutes/hours after I reboot the pi, then dies. this pair of errors are always there after a failure...maybe I'll do some research about resolving rpi i2c issues

Nov 10 20:23:32
Failed to initialize i2c. Errorpen /dev/i2c-1: no such file or directory

Nov 10 20:23:24
temperature sub-system. Failed to read sensor temp (return). Errorpen /sys/bus/w1/devices/28-01191245a033/w1_slave: no such file or directory

i2c issue happens when i2c bus is not enabled. raspi-config is used to set it. Once done it does not need to tweaked till reimage.
The second issue is one wire/ temperature probe. Thats different than the i2c issue. Nothing physical changed?

we are tracking this, but I think this will be post 3.0

Awesome. Thanks

Just found a small bug on v3.0-beta release, the graph on the Temperature page for the heater duration is taking the Y-Axis values improperly. See the image below:

Since the Y-Axis is starting from 25.66 but till 86 I think that value came from the Deg F range and hence it basically means that the line for temperature is almost not visible in this heater graph. Should I create a github issue or posting on the forums is sufficient?

 

[Blaxkin]

is there any way to eliminate the 127 and 85 degree peaks from ds18b20 ?
the pikes comes only every 20-40 minutes :-( so the best was a software way ?

 

[adityaduggal]

Was this for my reply, since the left hand side graph does not have any such peaks and the right hand side graph's left-side Y-axis range is not matching with the temperature range in the Temperature only graph so I can't seem to believe that it should be due to 127 and 85 degree peaks from ds18b20.

I am not an expert but still whatever limited knowledge I have it seems that the right hand graph for heater's left hand Y-axis range is getting some values from deg F range instead of getting from deg C range.

i wonder if anyone else has come across this in pi3 beta?
I've been running 2.5 and using it to control my Jebao dosing pumps via PCA9685.

when i upgrade to 3 beta the tick box for PCA9685 in the configuration screen goes blank and when i recheck it and reboot the pi it goes blanks again and my dosing pumps no longer work.

I wonder if this is a known thing?

also on 2.5 the dosing pumps sometimes stop working and make a whining noise. i believe this is a known issue, hense the reason i want to get onto 3.0 as i believe there is a fix incoming for that.

no i have a problem with peaks

in my last post i describe the screen on my PC ... when i load reef-pi on my tablet i can now see the option to add a pca9685 driver.
when i try to do this (i don't change the default address or frequency options which are set at 68 and 1500 respectively) it fails with an error:
{"error"."failed to create. Error: remote IO error"} HTTP 500

has anyone else seen this, i'm using @Michael Lane goby board.

Default hexidecimal code for PCA9685 is 0x40, in decimal that wil be 64.

Convert decimal to binary, octal and hexadecimal

I was just looking this tnx BenB, 64 works. Anyone know why I cant delete wrong connector? It just cant be deleted.

Thanks Ben that worked
just for my own future reference how did you know the hex code for pca9685 is 40 / 64 ?

and something for @Michael Lane ... i'm afraid i've still got the dosing pump whine, tbh i wouldn't care but it stops the motors from turning at all.

edit:
just did a further test and all three pumps run fine at 100% .. i only get the whine at a percentage value.

ok, so I2C isn't related, darn. I was hoping I was getting close to root cause.
Nothing changes between working and not working. I don't have things tidy, so I suppose something might be flinching and causing an issue (like the voltage doohicky that powers the ADJ relays, which is just floating right now), but with everything just sitting there (3 lighting timers, ATO is on a timer for 5m every hour, that's about as interesting as it gets except when I raise the lights for feeding). It'll work for an hour or 5, then dies with these errors...weird, right?

40 is hexadecimal , translated to 4x16 + 0x16 =64 in decimal. the ui takes decimal number. I think we should improve the ui to support hexadecimal natively.

You can hook up to 62 pca9685s when you change the adress by connecting solderpoints on the board

Well, I had to sign up for a new forum due to this one. I've only had a chance to do a quick overview, but looks like this project is alive and kicking, and I'm ready to dig deeper.

I've got a background in electronics manufacturing, so hopefully I can contribute to the overall project as needed. I may have to finally figure out how to use github (always found it a really annoying file system to be honest).

Anyway, back to reading and trolling to see where things are, where I can help, and where I can pick up and start building one of these.

thanks Ben ... every day's a school day. I'll check that out

What frequency are you using...you may have to tweak that to get decent results
