Thank you, I'll try that when I reach back from work.sudo systemctl stop reef-pi.service

Do it when you get home. It's going to completely wipe the reef-pi, including any login information.Thank you, I'll try that when I reach back from work.

Ok, I've done it and installed 3.0, got the temperature sensors working, it's late now and I'm too tired to figure anything else out. Lots of things not running right now! Something's in my notes aren't making sense, so I'll need to open everything up tomorrow.
Quick question, do I need to reconfigure everything from the console again?
Hi all.
second post... first question:
Is it possible to connect the BS18B20 temperature sensor to the raspberry? which jumpers?
Check out the temperature controller guide in adafruitHi all.

In other news...I've never got email working with reef-pi. Currently getting this error when I try to send a test message after configuring as well as I can think to:
{"error":"Failed to delete. Error: 534 5.7.9 Application-specific password required. Learn more at\n5.7.9 https://support.google.com/mail/?p=InvalidSecondFactor o73sm12993889pje.7 - gsmtp"} | HTTP 500
I copied the password out of lastpass, so I don't think it's that. port? config in my email account? I really want to do it with a '+reefpi' in the email address to help filter it, but I'll settle for almost anything...thoughts?

looks like it's the story. It took a reboot of the pi after setting it, which was weird. but now I got my test message. Thanks!If using Gmail with two-step verification on, you might need to use an App-specific password which you generate in your Google account Security Settings.
Yup, thats what the error is all about. Use application-specific password (link is in the adafruit first guide)If using Gmail with two-step verification on, you might need to use an App-specific password which you generate in your Google account Security Settings.
Kinda like the 'personal access token' you can use in GitHub and others, I suppose. Makes sense, I probably should have thought of itYup, thats what the error is all about. Use application-specific password (link is in the adafruit first guide)
Ack. Its kinda expected, since they are sharing one common bus, one bad sensor can impact the rest. I'll also search if we can safeguard this with some circuit modificationPSA:
I've been fighting my temperature control on reef-pi for months. couldn't figure it out. It almost always would start working again after I power cycled the pi, but for an unknown amount of time; sometimes several seconds, others for hours. But within a day or two (most often an hour or two), all three sensors would crap the bed, getting errors in the admin tab that the file didn't exist. the chart would have a zero point at the end and stop tracking temperature data. When I'd go look, the dropdown to pick the sensor would be empty as if nothing was plugged in. Then I'd reboot and they'd (almost always) come back, but not for long.
I saw someone recently on this thread with somewhat similar issues and they found one sensor was bad (the issue went away with one unplugged). I pulled two yesterday and... lo and behold, it was still reading today. I turned it off tonight and plugged in one more. Within a few minutes, the old problem was back. I swapped the 'new' one for the third one and I'm still going well a few hours later.
So...if you have temp sensor issues in your reef-pi, it's likely a bad sensor and you can diagnose by pulling one at a time.

@Ranjib just FYI
The ui directly don’t expose this value (something we should fix). You can get it via command line using api or if you use the JavaScript console in your web browser, under the network tab you’ll see the probe details (including calibration details) in reopened values when you click on ph tabHi all! Can I get calibration values from gui for ph probe exported? like in calibration json file. So if I delete ph, I can put callibration numbers in with command and using this json modified file? I recently recallibrated ph probe and now it goes from -3600, so graph is linear.. I would copy somehow this numbers and past them in json file... tnx
The DS18B20 connects to the Raspberry Pi using 3 of the pins: 3.3V (pin #1, top left. Only pin with a square solder pad on the back), ground (pin # 6, 9, 14, 20, 25, 30, 34, or 39, just pick one), & any of the GPIO pins. You only have to use one GPIO pin to connect as many sensors as you want, as they use the 1-wire interface.
