Also, since I don’t need reverse can I just bias one side of the motor to ground instead of running two jacks to each motor? If this where the case I could just do some reorganizing since my current setup is using 2 GPIO pins per motor.

 

[Des Westcott]

Sounds like a plan

It's been 1 day since I downgraded to 3.3.1 and I have no errors now.

I need to wire in 2 more dosers. The problem is I am out of GPIO pins. I do however have a PCA9685 board installed and running my other two dosers. Is it as simple has creating an outlet using one of the open PCA9685 pins and jacks on two more? Can the PCA9685 do both outlets and PWM jacks at the same time?

Yes, you can, I am running both on one pca9685.

That is an other option, i have done that with a pca9685 running 4 docers, only one way (no reverse).

 

[b4tn]

Awesome, both ways are possible but running off spare PCA9685 pins is much easier. I can just plug a jumper in without having to take the whole assembly apart to re route wiring and solder more pins.

Hope this is a good place to ask this.
But I have a 300w Marsaqua light and the Michael lane control board.

any Guidance on hooking this up?

I'll throw my 2 cents in to get this ball rolling..
Should be plug and pray..
Let others verify..

Probably need to unwrap that large ribbon cable so the 2 reach the board.

In the afternoon I downgraded to 3.3.1 too... no temperature sensor errors and the UI in the dashboard is fine... also the color of the equipment (the heater is rightly red... not working!!!)

That's exactly right. Unplug the 4 pin cables from the knobs and plug them into the adapter. Hook up GND from your rpi to the middle pin of the 3 pin connector, and a PWM signal to the other 2 pins on that connector.

Second one is a slave plug for other lights..
Just for clarity..

That's the right idea, you just need to reverse the steps in your "Day On" and "Night On" Macros for it to work right. It needs to be written backwards in reverse state for it to work.

So "Day On" should read:

1. Humidity Day -> Off
2. Wait 60s (Or whatever value you want if you want that)
3. Humidity Night -> On

So when the Timer triggers this macro, it will turn Humidity Night off, wait 1 minute then Humidity Day On.

It's a bit Bass Ackwards I know, but that 's how it works at the moment. The Dev's are working on sorting it out though from what I know

soo...
dont know if it works like it has to.. now i mis my readings between the selected "night" time.

so it just stops at 18 and starts at 8 in the morning...

You have two Humidity Controllers now. "Humidity day" can't record what "Humidity Night" does. Or put another way, "Humidity Night" cany show values from when it's off.

Maybe setup another Humidity monitor that doesn't get turned off, but doesn't control anything and use that for continuous display.

 

[Des Westcott]

But your graph suggests it's working correctly.

ok so i see that with the macro the equipment changed to day and night! To have 1 graph that includes day and night i just add another PH monitor for the humidity! I think i got this! :D

Sound like you do!

Before I reach out to xfinity tech support I was wondering if anyone else is using the xfi pods (xfinity's propitary mesh hardware) and having connection issues? I can only connect to iot devices if both devices are either connected to the same pod or at least one is connected to the gateway. For instance both my reefpi and my lights are connected to the basement pod. If my phone is connected to the bedroom or kitchen pods I cant connect. As I move downstairs my phone first moves to the gateway and am able to connect then to the basement pod and am able to connect. The strange thing is it does connect but so slow it wont load completley. Does the same with SSH and other IOT's I have. I been through all the settings and dont see anything useful.

Thanks a million.

Last Thursday I was updating my Raspberry when suddenly it rebooted (I had setup crontab to automatically reboot every day.... and I was so lucky it happened in the update). The update was still in progress.
The Operating System on the USB Pen Drive (I don't use the Micro SD) obviously crashed and the raspberry didn't reboot.
I formatted the Pen Drive, I installed Raspbian and I installed reef-pi 4.3.

I'm still waiting for the Rob's controller, so my Raspberry has 2 temperature sensor connected and 1 TP-Link HS110 smart plug is connected wifi by reef-pi.

With the old version (3.3.1) I NEVER had any kind of problem (except some Adafruit error logs I receive in Configuration --> Errors that I can understand. Temperature data are always updated on my io.adafruite space).

Right now I have the following troubles:

1) In the dashboard, the Equipment chart is not centered (see the first attached pic).

2) in 3 days I had 3 emails because of a temperature sensors failure.
The message are:

- For the temperature sensor INSIDE the fish tank: "Temperature sensor failure. Error:read /sys/bus/w1/devices/28-011921559d98/w1_slave: interrupted system call"

- For the temperature senser OUTSIDE the fish tank (it is "hidden" in the living room just to control the temperature of the room): "Temperature sensor failure. Error:read /sys/bus/w1/devices/28-011921d14102/w1_slave: interrupted system call".

The same error can be read in reef-pi (Configuration --> Errors (see the second attached pic)

Do you have any suggestions?

P.S.: I had the other errors in the log

Did you revert back to older reef-pi or still having this issue ? I suspect it’s something to do with the newer raspbian

 

[Ranjib]

Hey devs.

my reef-pi build seems to get laggy every few days and eventually seems to restart. Not sure what the trigger is, but memory use seems to sawtooth, so maybe some sort of memory leak?

The reboot issue isn’t a terribly big deal For me, but is does highlight one other issue I think I need to fix: each time it crashes I lose control of the HS300.

@Ranjib I remember you saying there was a fix I could do for the network connectivity problem but couldn’t find it. Mind repeating what that was and I’ll add it to the manual while I’m at it.

Add a wait till network come up directive on systemd unit file. I’ll dig up the detail ...
