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

I2c is made for short distances, so this isn't very surprising. Shielded cable may help, but 25 feet is still probably too much. There are i2c bus extenders that could help with this. P82B715 seems to be a fairly popular chip for this. Sparkfun also sells a breakout board based on a different chip (https://www.sparkfun.com/products/14589). I haven't tried either of these, but they seem to solve the problem you are experiencing.

Actually it depends on how you Connect them. The one Wire protocol website has a lot of info on this. around page 200 of this Forum is where we were discussing this.. Star network topology is the issue with distance. I have 6 probes working (as a test) one is 30 feet each of the others Drop off the 30 feet long wire at near equal distance between them With the Longest length closest to the end segment( SLAVE) Shortest close to master .

I was not asking if or how it can be done ,Just pointing out that connecting them all at the same Point Not inline can cause a issue..

Sorry i have not been active here. I have been swamped at work and reworking my Whole Aquarium and Sump room setup..

Hi @Ranjib I am hoping to get back to work on this project very soon. Thanks again

No need to say sorry :-) , we’ll be right here , chime in as and when time permits . Personal life is more important , this thread will run for years to come :-) (hopefully ). We are wrapping up 2.0, next year will be clustering , calibrations etc . I hope we’ll get to do some ML stuff after that

Some setup help please. I have power somewhat working with the relay board. I realized my outlets were running opposite for heater and chiller when they would say on they would turn off and off was on so I wanted to edit the connectors, but only the red X for delete was there and it told me it had equipment connected and error, so I turned off the control in the temperature section, tried to delete the equipment but it still said in use. So basically I can not delete or edit settings, I assume i am in an odd mode or something. Any help appreciated. I assume once I get back to it i just tic the reverse box.

Even disabling the temperature completely it still says error equipment in use.

Which reef-pi version you are running ? Can you check if you can edit the outlets under configuration-> connectors and enable the “reverse” checkbox ?

 

[speedstar]

I see on some screenshots there is an edit button, but on my version there is only a red X. Is there an easy way to see the version.
I can not edit them, the reverse was there when I set it up.

The dashboard says running 1.0 if that is the version. I am on a 3B+

Hmm..that’s very old .all the new stuff (like edit features ) are available in only 2.0 series. You’ll have to delete and do a fresh installation for upgrade

 

[speedstar]

Just upgraded to 2.0.0-rc0 is this where I should be?

If you are comfortable with command line foo, I think there’s a way to update the outlet via api , using curl in command line. Let me know if you are up for that, I can share examples

Yeah . Try recreating everything

My upgrade I must have done incorrect, as it it remembered my old connectors and has them locked in use. ( I could reverse them now and edit, but wont delete) I also can not add devices or get the temp probe working now that had been correct. Is there a command line to delete everything so I can start over?

Yes. This is what I was trying to say. Just stop reef-pi and delete the data base (mentioned as resetting database under troubleshooting guide here: https://reef-pi.github.io/additional-documentation/troubleshooting/)

I just did this it states that it is up and running, the are no errors in the journal, but I can not access the browser connection anylonger it says unreachable, both trying the pi IP and the name.local. This just changed after resetting the DB, prior it was connecting fine. Thoughts?

What’s the log saying ?

Refresh your browser if that doesn’t not resolve see if incognito mode you can access it

I think I am working again, I bounced to the 2.0 Alpha, then back to the 2.0 full release and all is running fine. Very strange, but atleast now i'll get some sleep, work in 5 hours eek. Thanks so much for the help will update progress tomorrow.

Sorry for the troubles, keep us posted.

Thank You, nothing to be sorry about, I was the person that installed the old version to start. Just glad it is running, just tested the email alert. Worked terrific. Now to bed, i hope this is too much fun!

Sorry i really do not know that for sure we should have a expensive calibrator to know that.What i try to do i have 3 different temperature reader,so i try to take the average.

 

[speedstar]

Is there a max length or suggested cable for the temp sensors?

Thanks

 

[janos]

With silicone being an insulator, that doesn't skew your readings?

Try to take average of 3 different reading.3 different temperature instrument
