This ArdBir Panel, designed by Gutosan. I had it uploaded to a local 3D Hub...

All components including the extra ordered
Base plate with 12v= Powersupply; SSR for the heating and relay for the pump

The ArdBir is a single board Arduino Uno based system. It is open source everything is available at Github It is design for a single vessel BIAB system. And it is ready to use for the Grainfather.
In short. With the ArdBir you enter the whole process. From filling the GF up and including to...
I don't stir the wort. It is done by the reciculation. I take a lttle bit with the hose in a cup. Leave for a few minutes and take the sample with a pipette from the cup for my refractometer. I don.t use a hydrometer.

The pump control is already there in the ArdBir. The heating is controlled with a SSR and PID / PWM in the software. This is more acurate then just on/off. Ofcourse it is an other price.
See this video on the use of an Open ArdBir and the GrainFather.
The software is open source and the hardware based on an Arduino Uno. It cost a bit more and you have to do a bit more DIY. See also this link
Measured the temp with an alcohol thermometer at the end of the tube during recirc for a number of times. It was only a difference of 1°C. This could be also the difference between the STC-200 and the thermometer. I found it OK
