yes i did.
the problem wasn't just the adruino.
for some reason the internet browser on the PI I was using would not work well with brewpi. I used the midori browser and everything popped up like it was suppose to.
Running it on a 15' display.

Anybody uses I2C LCD 20x4 on your build? Could share the step by step?
day trippr with your bluetooth idea would something like this work? It's using a DS 18b20, just not sure if it's available as a bus device.
As I posted yesterday, I'm messing with the inaugural run of my BrewPi set up. I got home to find the freezer sitting at a chilly 9 degrees F and the beer at a crashingly cold 36! At first I thought the F/C toggle had been switched. Nope. Checking the device configuration showed a duplicate chamber heater on pin 5 which is the same pin as the original chamber cooler. At some point when the BrewPi called for heat it energized the impostor relay and the system was caught in a loop ... running the freezer while thinking it was asking for heat. It had been working fine for about 18 hours prior to this with the freezer and heater tag teaming to hold the target temp. I reset everything, unassigned the rouge device and put my beersicle back in to dry hop at a warmer temp.
So .... gremlins, short circuit? I do have things sort of hanging about until I can get them in an enclosure. Hopefully there won't be a repeat this evening.

Remember, you are doing everything from a browser interface. Clicking apply isn't enough you have to refresh sometimes to make sure your settings go through. I click apply then I refresh the device list everytime to keep this from happening.
Well, so far no joy. Luck hasn't made an appearance tonight.
I'm trying to use a small AVR script and simple wiring setup that purports to take strings sent to the Uno over the USB side and send them on out to the HC-05 through a software serial port. It also enables a wire function that allegedly forces the HC05 into AT mode at 9600 baud.
You'd think that's all so simple it should just work. Well, I can see symbols going into the serial side RX pin of the HC05 but it never sends anything out its TX pin to ack the AT commands I'm sending.
On top of that, I just noticed that Windows sees the module as an HC-06 not HC-05. Not sure what that means yet.
You'd think you could just program the darned thing through the Bluetooth side but noooo.
More when I get to it. Right now I need a beer...
Cheers!
[edit] The module can actually drive its transmit pin - verified by using BrewPi to try to program the Uno over the Bluetooth link.
Wiggles the heck out of the TX pin - just not at the right speed. So it's not broken, it's just being recalcitrant...
If using a pc as the RPI, does the computer have to be attatched to the arduino at all times? I have an acer aspire1 that would be perfect as a linux based device for this purpose. However, I want to use it as more of a monitoring device whereby I may carry it with me and check the data on my brew. If it must be connected is there anything (economical) I can use as an alternative to transfer the data to this pc via wifi? Keep in mind I know nothing of this stuff. Just want to nerd out on my brews.

I am mounting 2 arduinos uno with one raspberry and my doubt is if have a way to turn one arduino off but no unplugging the respective cable. This situation occur when only one fridge is fermenting, and the other one is waiting the next batch.

My BrewPi is currently set to 40 degrees Fridge Constant, and it says it is cooling, but it is not running. I suspected the fridge may have died, but a reboot caused it to cool for a bit, and then give right back up. Everything was fine, and nothing was touched to cause this change. Any thoughts?
