Home Assistant GivEnergy (GivTCP) inverter timeout restart with backoff

config.yaml

alias: Inverter timeout response with backoff
description: >
  Periodically checks if the inverter timestamp is stale (>3m30s). Stops GivTCP,
  waits 7 minutes, restarts, then waits a further 2 minutes and checks whether
  comms have recovered. Increments a counter on failure (for backoff) and
  resets it on success.
