I have found this to be the best solution to pours not working.
- Turn off tablet
- Delete taps and meters from the server
- Reboot server
- Start tablet without keg board(s) connected
- Connect kegboard(s)
- Kegbot will detect the controller and ask how many meters are controlled.
- Select how many it controls
- Do a test pour and the tablet should say "kegbot detected activity on @&$&@%#-.flow0 (or flow 2,3,4 depending on the number of meters per board)
- Add that tap on the server side and attach the appropriate flow meter to it.
- Repeat 8&9 for each tap.
I have to do this whenever I attach my meters from my kegerator to my jockey box.
