That us awesome.... hope your 1st all grain is awesome as well!

I think there is another resistor used to check the wire resistance on a three wire pt100. It is the one that you have to manually enter into craftbeerpi. I am using a pt-100, have this field set to 430 and mine works great, but I believe there a major variances on the value of this resistor.

Update... still working flawlessly

I bet your sensor resistance is not 430... find the correct resistance and make the change... bet it works

I believe the 3v3 is not needed (mine is not hooked up). I understand it to be an extra output voltage source, if you need to run something else.

I think there is a "resistor" setting for the probe/max board. I set mine to 430 I think. I will check this evening. Did you set it?

Update.. first two probes still working perfect. I added another pt100 sensor and the same thing happened to it. Went crazy and then smoothed out and is working fine...

Yep. The soldering was hard for me as well. I had to go to harbor freight and pick up one of those table top magnifier/light things to get it done, especially removing the trace between those two tiny blocks... Also... use the craftbeerpi 3. I started with the 2 version... don't use it.

Side note on the 1811.42 F reading... When I first ran the first two pt-100 sensors they gave this reading for a while. It would read 1811.42 for a while then it would read correct temp for a while. It finally just read 1811.42. I left it run and after quite a while it started reading correctly...

The 1811.42 F reading is the reading I got when the pt-100 sensor was not hooked up at all. Make sure you use the gpio pins I used. I think I read somewhere the software requires certain pins for the max 31865. let me know how its going

Ok, Here is my full schematic. They carry over from left to right page 1 to 3.

They do... I forgot to attach all of the schematic. I am at work, but when I get home I will post them. I am using 6 ssd's, so I took one wire (ground) from the ground on the pi and jumped it from one ssd to the next. The positives I ran from gpio's to each ssd.

Solved,,, I found this some where on the internet: " The service runs on the Pi and does not need network/internet access. You can try using localhost:5000 or 127.0.0.1:5000 on the pi directly. If you are not on the pi directly, then you would need network access. localhost and 127.0.0.1 are...

Hey Guys, I have my ferment controller all put together, but have a problem. I housed the thing in a steel ammo box. When I shut it I lose my internet connection and craftbeerpi wont work. I also have @LINK internet, which loses service about once a week. I want to run craftbeerpi completely on...

I thought I would attach the wiring I used. Forgive my schematic drawing skills!
