Trimatik MC is an older heating control from Viessmann. It has no supported digital interface for remote access, but I found at least two ways to get access to sensor data like various temperatures and state of relay contacts. One way is to use the so called remote control the other use the clock timer. This project will use the latter way, because the hardware adaption is much easier and and all four timer channels could be controlled as well. Remote access will be done via an ESP32, which emulates the clock timer and gets/pushes data via WIFI.

There are a number of items related to doing Virtualization CI and testing which I have a hard time getting to during my day job. I'll take Hackweek as an opportunity to get at least a little out of my normal space and improve our methods. This mainly focuses on QEMU/KVM and some of the efforts and infrastructure I've already got in various states of development, or at least investigation.

DRBD refers to block devices designed as a building block to form high availability (HA) clusters.Also possible to combine multiple devices driver for Linux(MD) and the network block device(NBD) to achieve similar functionality.
