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

Welcome to reef2reef, you'll love it here.
I'll need little bit more details, like what version or reef-pi you are running? What are you seeing in reef-pi temperature tab, particularly in sensor drop down? Can you check the logs as well for any error? What python script you are running to check temperature sensor?

I am running version reef-pi-1.1-pi3.deb
2.55 MB. On a Rasp. 3. When I look at Reef-pi in the temp tab I see that it is enabled and temp graph that bounces between 78 -80. I am running sudo python temperature.py to check the sensor. Being noob not sure how to check the logs as well check for errors. Thank you for getting back to me
so quickly.

did you confirm this is correct
https://reef-pi.github.io/general-guides/install/

• Enable i2c,onewire,spi,uart: Different types of electronics in reef-pi requires a number of kernel modules and device drivers to be loaded in kernel. Edit /boot/config.txt to load these modules

dtparam=i2c_arm=on
dtparam=spi=on
dtparam=audio=on
enable_uart=1
dtoverlay=w1-gpio

• Configure ssh: ssh is used to remotely control and troubleshoot the Raspberry Pi.

sudo systemctl start ssh.service
sudo systemctl enable ssh.service

• Set time and date: Configure raspbian to use network time to synchronize its date & time information. Also set specific locale, to reflect the local time instead of UTC

I checked these as you suggested all seems right.

Do you have dev_mode enabled by any chance? can you share a screenshot of you configuration -> settings UI as well as your temperature UI and dashboard,

 

[Johnny's300]

Again noobie here. Dev_mode?

 

[Ranjib]

Again noobie here. Dev_mode?

you want to uncheck the dev_mode checkbox under configuration and restart reef-pi.

 

[Johnny's300]

Ok I unchecked dev_mode and rebooted the pi. No change.

can you share a screenshot of the configuration -> settings tab as well as dashboard again,

 

[Johnny's300]

Sorry my bad forgot to hit update after unchecking dev_mode. The temp is now reading 81° pretty steady. But the sensor is in ambient temp. of a room that is 74°. When I run sudo python temperature.py on the raspberry pi ui it the sensor is reading a fairly constant 74 as well.

 

[Johnny's300]

Just looked again at the reefpi temp and it is working know. The temp is off by about 10°. I am assuming that is a faulty temp sensor maybe. Thanks again for your help.

Crosscheck reef-pi values with your python script , if they are same then the sensor is faulty , else we have some bug , either in reef-pi or in python script

Think I have found a little bug in the 2 beta7 the interval the temp is set to update reads as set to seconds but it actually updates as minutes instead, not sure if that has been picked up yet.

The check interval itself is in second: https://github.com/reef-pi/reef-pi/blob/master/controller/temperature/tc.go#L131
You'll also see corresponding log statement (reading temperature sensor ... ) at the expected interval, but the telemetry data is stored at per-minute interval at minimum, as a result you may see multiple entries in the chart with same timestamp (like if you have set interval to 10 second, you may see 6 points in the chart with same time stamp, since they belong to same minute), this issue (timestamp granularity in charts ) is not a problem in temperature usage chart (aka tc or temperature control) which shows hourly average of temperature along with heater/chiller usage.

Good morning to all,one simple Q: it is possible my temp sensor is so good and stable,like this pics?Cooling fan is turning on and off so it is working.Just as i see another people charts it is all over and my chart is stable.

Looks normal to me.

Thank you Ranjib first good news after long time.That is my 4th RPI3 so now something must be good.Thank you

That will likely be an issue with the relay, not the pump. All relays can fail and unfortunately yours happened to fail in the on position. It's likely just an unlucky failure. Someone posted a video earlier about cheap relays vs expensive ones and their failures, at the end of the day the cheap relays will almost always be good enough for our purposes but there is always a chance one will fail.

Actually, I changed the wavemaker to another relay and promptly burned that one as well. I have been advised that it is more than likely an inductive load as the wavemaker only draws 1A, but the relay is rated to 10A. I've been advised the following "
[11:46, 8/13/2018] Gaven Marines: If the 220v side then yes I really think that is the problem.
[11:47, 8/13/2018] Gaven Marines: Order a 1N4007 and place across the output of the relay. Make sure polarity correct. Leaded component. Will sort that out 100%"

I am running reef-pi-2.0.0-beta-7-pi3.deb on an RPI 3B+. it will not reload for me. I have re formatted and re installed and still nothing. Can anyone help?

Need more details. Can you share some UI screenshots. Please dont reformat and reinstall unless you know whats the issue, that will only make it harder and longer to detect whats wrong.

Hello reef2reef family,
I am happy to announce the immediate availability of reef-pi 2.0.0-alpha-0. This is the first alpha series build, which means its not a final 2.0 release, but its also not a beta release, i.e. no more breaking changes will be allowed after this release. We'll only work on bug fixes or any feature that can be implemented without breaking anything existing (unlikely, given the public release date is approaching soon). Major changes in this release:

Features:

• Errors UI: Users will be able to see specific server errors via UI and clear them
• UI validation on signin page by @Ranthalion
• Send test email/sms from UI (to validate email configuration)
• Allow editing existing timers via UI
• Summary information now includes "error" details, and presented as a consistent footer

Bugfixes:

• Timer UI was setting enable field to false, resulting in disabled timer job
• Removed all mention of "Equipments" from the codebase, UI & api

Release builds can be found in usual location: https://github.com/reef-pi/reef-pi/releases/tag/2.0.0-alpha-0
Previous equipment setting (< 2.0.0-beta-7 ) will be lost. Other than that, everything should be fine.

Please give this a try if you have a test build or starting with a new build. I'll exclusively work on bug fixes and documentation till we hit the public release. If we dont encounter any bugs (... unlikely) this release itself will become the final 2.0 release

happy reefing,
ranjib

Will try to install this tomorrow
