my new pi3 pi-zero W and a few other bits of hardware came in today.

Now i just need to get it all out of the packaging

Too much technology ..

On this note,
I'll be adding support for sht31-D temperature/humidity probe in reef-pi 2.0. I have a feeling my ATO intake anomaly has to do with these two

@Ranjib were you able to incorporate this yet? I haven't seen anything mentioned, but I was going to ask about it and did some searching through the thread and found this post.

Thanks

Not yet. I am working on improving the UI currently. Next focus will be documentations, and then finally the macro feature. After that 2.0 release, after that new drivers (sht31-D, mcp4725 & mcp23017)

can never have too much technology lol

Thanks, I thought maybe I had missed something. From the first time I started playing with Reef-pi I was thinking it would be nice to have a built in DHT11 or 22 to report back on the ambient conditions.

Meanwhile, you can always use a ds18b20 outside the aquarium to get room temperature, now that reef-pi supports multiple temperature probe. We have to wait till the sht31-d integration lands. Currently I do not have any plan to integrate dht- series sensor though, they are relatively inexpensive but will consume GPIO pins, sht31-d is more precise, bit costly, but i2c based, so no additional pin requirement

Cool. I'm using a 2nd ds18b20 for room temp

Hi to all,would like to ask some help with the timer.Try to turn my sump light on at 18.00 and off at 9.00 not working for some reason.Thank you

Does your reef-pi time reflects the correct local time, i.e. the summary information below the dashboard, where it says "Sun Jul8 03:36:47", is that correct?
If its correct, next check the reef-pi log around that time

Code:

journalctl --since "2018-07-07 17:00" --until "2018-07-07 17:02"

you should something similar to this(time, pin etc details would be different of course):

Code:

Jul 07 17:14:00 dev-zero reef-pi[8605]: 2018/07/07 17:14:00 Setting GPIO Pin: 24 State: 1

Hi Ranjib thank you for your time and help The time is not correct,i think i need to adjust.the rasbi-config would be the right place for that?

yes.
here is a tutorial for that: https://learn.adafruit.com/adafruit...-2-first-time-configuration/changing-timezone

Thank you now is working.Hope you will stay more in the forum,with this project,everybody need your help.Thank you again.

I would definitely stay active, but I do think things will be better once we sort out the documentation (i'll get back to that soon, right before 2.0 release).

@Ranjib, sorry to bother you but I'm having an issue. I'm trying to set up the lighting controller circuit using the pi's pwm on ver 1.5. I get no voltage change and when I check the reef-pi status I find an error "ERROR: lighting-subsystem: Failed to set pwm value. Error: open /sys/class/pwm/pwmchip0/export: no such file or directory". I'm using gpio 18 and 19, set up just as I would using the PCA9685 breakout board. What am I doing wrong?

Did you enable pwm in raspberry pi? You have to edit the /boot/config.txt to load the pwm modules
