+obsolete earlier ones, they're just different):

+| Name | Status | Language | Tested-on | Description |
+|--------|-----------|-----------|--------------|-------------|
+| __x1__ | Archived | Bash, AWK | Ubuntu 16.04 | Single, synchronous script, saving state in text files |
+| __x2__ | In-use | Bash, AWK | Debian 10 | Parallel processes: collectors, cache and reporters; passing messages over pipes |
+| __x3__ | Scratched | OCaml | Debian 10 | Re-write and refinement of __x2__ |
+| __x4__ | In-dev | Dash, AWK | Debian 10 | Sensors are completely decoupled daemons, cache is a file tree |
