-Getting voctolight on both tallycoms to (manually) work took unnecessarily much time. It boils down to being new to the matter, wrong labels, wrong config and different behavior after correcting the config, due to different base OS versions ([[https://www.raspberrypi.org/forums/viewtopic.php?t=187225]]).

 === Step for step rebuild ===
-Below is written from scratch, so that someone who brings their (linux) laptop and never worked with the VOC before, has a good starting point. This section can be moved to a separate page in true wiki fashion.
+This section describes how to (re-)setup a tallycom from scratch, that should enable a VOC rookie with a linux laptop to go right ahead. **WARNING: Due to time constraints no tallycom was actually re-flashed and the steps below are incomplete. If anything, they should be seen as a rough guide. Feel free to extend.**
-== 1. Flash latest Raspberry lite ==
+== 1. Prerequisites ==
   - Ensure that you have access to this wiki. If you haven't, you can't read this. :brain_explosion:
+  - If DHCP doesn't work, have someone from the VOC team reserve and hand you a [[intern:archive:netzplan|10.73.100.{1..254}/16]] address. Configure it manually. <code>
+IP: 10.73.100.X
+SNM: 255.255.0.0
+GW: 10.73.0.254
+DNS: 10.73.0.254
+</code>
+  - Install ansible and git <code>
+user@laptop$ sudo {dnf,yum,apt-get} install ansible git
+</code>
+== 2. Flash latest Raspberry lite ==
   - Download + unzip the latest Raspbian lite - [[https://downloads.raspberrypi.org/raspbian_latest]] (at the time of writing April 2018)\\ **WARNING: 350 MB** - A lot in case of shitty/shared uplink... <code>

-== 3. Final ansible run ==
+== 4. Run ansible ==
+  - Get acquainted with the VOC [[:ansible]] repo structure
+  - Checkout the feature/tally-pis branch (**for now**) <code>
+user@laptop$ cd ~/Documents/voc/cm/
+user@laptop$ git checkout feature/tally-pis
+</code>
+  - Check if the event inventory file contains correct mapping of tallycom IP to the variables that end up in the voctolight config <code>

+  - hosts: tally-pis
+    roles:
+      - { role: common, tags: ['common'] }
+      - { role: tally, tags: ['tally'] }

   - Run on multiple tallycoms - **WARNING: placeholder only** <code>

+=== Conclusion ===
+The tallycoms were in an undefined state. They should either be checked prior to sending them out to the next event or a solution should be provided to quickly reset them at the event. One solution could be to have (pre-baked) working images per device (on e.g. the local encoder), which just need to be flashed to a microSD card, stuck back into the tallycom and $profit. If pre-baked images seem overkill, the process of flashing them with a base OS and running ansible against them should be made more straight forward/documented better.
