# bar-tracker

Runs continuously, once a second. Watches the pulses `bar-detection` writes and keeps the
oven's bar record in the customer database:

- On a rising edge of `in-detect-oven` (11) it inserts a row in `oven_bar_enter_detection`
  and opens a row in `oven_bar`.
- On a rising edge of `out-detect-oven` (12) it inserts a row in `oven_bar_exit_detection`
  and closes the oldest open `oven_bar` row, or inserts a closed one if none is open. It then
  reads `THprocess` (17) for five ticks and writes the maximum as `bar_temperature` on both
  rows.

The first tick only records the current values, so a restart never fires a false edge.

Needs the db-controller reachable from the job's sidecar, and the three `oven_bar*` tables in
the gateway's customer database. Runs in `docker.izazpi.cloud/aml/aml-python`; the version is
in `schedule.yaml`.
