This one introduces only a few new features w.r.t. the previous one, but adds some small improvements and bug fixes. For the full list of changes and additions see the Artisan change log.

Roast Phases, Statistics and Phases LCDs

The coffee roasting process is often discussed with respect to its separate roasting phases. Splitting not only makes it easier to get complex things into our small heads, but also allows for colourful roasting graphs.

Giesen Roaster Connected

A number of people have asked how best to connect their Giesen coffee roasters to Artisan. Here is a quite elegant solution by Barry that brings his Giesen onto the network for remote access. He owns a 2016 Giesen W6A propane drum roaster, which is equipped with the dual probe options by the factory. So it has a PT100 dual probe measuring environmental temperature (ET) as well as another PT100 dual probe measuring bean temperature (BT). For each of those probes, one channel (pair of wires) is connected to the Giesen control panel. In the following Barry shows how to connect the second channel (pair of wire) of each probe to some magic, such that Artisan can log its readings over the network.

Note: since Artisan v1.3 Giesen roasters are supported directly via their network connection.
