Any one using this controller to delay the start on brewing ?
Just wondering how others are going about it

Thanks djardjar007 said:It's in the code. A start later option. Set time and it delays start. That's the ardbir code. Check out open ardbir Pdf.

I have a little problem or I don´t know what happens. I just update my system to this new version of ArdBir (ArdBir_2_6_70b7) and I try to do the most accurate config but without success (or close).
In resume, the only thing I don't get is when in the boil, if the pump doesn't work, the measured temp don't actualize very well and sometimes have a 5 to 10 degrees (Celsius) of difference.
Any tip?
PS: I tried different configs to PID (kp, kd, ki), windowset, calibration, outside, inside probe, etc. With Mathos original works with no problem.
Thanks,

Yeah, I thought it was an EEPROM issue but I initialised it as per the instruction manual, the negative temp calibration still throws the temp reading off by 26 degrees or so.lael said:You need to configure the entire unit. Its pulling values from eeprom that are not relevant. I had the same thing and then, You know, read the instructions

I just discovered a bug in the temperature calibration that might be relevant.
When I uploaded the latest ArdBir sketch 2_6_70b7 (previously used Mathos code) I noticed that my temperature probe was incorrectly measuring 47 degrees Celsius, but when I load the mathos original sketch it correctly reads 21 degrees celsius.
When I checked the calibration temperature in the PID config menu I noticed that the value was set to -0.1 degrees, when I tried to compensate for the higher value the maximum adjustment that I could enter was -5.0 degrees and this resulted in the display showing 42 degrees celsius (again incorrect).
When I changed the calibration value back to 0 (or any positive value), the display showed a correct temperature of 21 degrees celsius.
It looks like any negative temperature adjustment causes the temperature to read incorrectly.
I tried several other earlier sketches and got the same calibration error problem with negative adjustment values.
