description:
 This check monitors an individual home battery storage system reported
 by an openWB wallbox controller. It reports fault state, state of
 charge, current charge/discharge power and daily imported/exported
 (charged/discharged) energy.

 Data is collected via the special agent {agent_openwb}, which polls the
 read-only openWB simpleAPI HTTP endpoint
 ({/openWB/simpleAPI/simpleapi.php}) and auto-discovers configured
 batteries by probing a range of numeric IDs.

item:
 The battery ID as reported by the openWB simpleAPI.

discovery:
 One service is created per battery ID that the agent discovers.

params:
 The rule "openWB battery state of charge" allows configuring lower
 WARN/CRIT levels for the battery state of charge.
