A few Issues or How brew day almost went down in flames

[derfburg]

Not sure where to start, here are the issues:

1. Probes just loose connection to MT.
2. My MT was working great for a month, was going to use it to ferment a new batch of wort. Sent a new profile to the unit from my PC and all hell broke loose. Both probes lost connection, The unit would click but not turn on the cooler.
3. Wasted 1hr and a few dirty words getting it work.

After plugging/out probes , setting up new profiles, going back to factory settings, updating, power cycling I got it to work. No idea what combo it was, what made it work but it did.

I have uploaded a video showing the probes issue. As you can see it is not even using one probe that is plugged in at this point. I am hoping it is user error.

I think I may be having a similar problem. The video you uploaded is saying "This video is private" however.
I'll upload one of mine some time this week too. The MT keep changing the temp into to --.- whenever it turns one of the relays on, and then the temp probe is also warm to the touch after. Stray current?

I think I got the vid unlocked now, give it a shot and let me know. Yes that is what happens.

• What version of software are you using? We put in some software fixes to address some similar issues in i believe version 1.1 or 1.2.

• What type of load is your unit powering (fridge?)

• Is it the probe or the input on the unit that isn't working causing the second temperature value to not display?

  • If it is the probe I can send you a new probe
  • if it is the unit we may need to send you and new unit...

The most current, as I updated during the freak out

What type of load is your unit powering (fridge?)
I will look and see what it is pulling, just an upright freezer, working fine now

Is it the probe or the input on the unit that isn't working causing the second temperature value to not display?
I am not sure how to tell, it will to the same thing if both probes are inserted at the same time. In the Vid one had been in longer is all

If it is the probe I can send you a new probe
What can I do to tell?
if it is the unit we may need to send you and new unit...
See Above

Thanks for the help, I will get that freezer info tonight.

Yup that is the exact same problem I am having. I am turning on a small 12V DC power converter, so not much of a draw, but turning it on is definitely somehow interfering with the unit.
Is there some kind of filter that can be built in so that current from the outlets doesn't interfere with the temp probes somehow?

[hebnern]

How is it interfering? We noticed that the probes would drop out or have spikes with the early software because it didn't handle errors reported by the sensor correctly. This was fixed in 1.1.0. Are you running the latest?

[zminette]

Not sure how, but whenever i use that device it kicks the BrewBit offline to the -.--
I just checked and I'm running 1.3.1 so it should be good with that.

I also played around with it a bit to try and isolate the problem, and even when I have the DC power source connected to the same OUTLET as the main MT power line it will kick the sensor off.

[hebnern]

Interesting. What is the power supply you are using? I can see if we can find a similar one and see what is going on.

[zminette]

It's a standard 5v DC power supply, that is wired to a grill spark ignitor. So when the power is applied to the transformer the sparker creates a spark to light the flame and it then kicks the sensor to -. - -
It's the fact that it's powering a sparker, if the transformer is connected to something else it doesn't do it.

I also have a 5v DC power supply connected to a 12v cpu fan, which is used to move the air inside my fermentation chamber. I don't see any issues when that device is running.
