◆ schedule_reboot_()

void esphome::hydreon_rgxx::HydreonRGxxComponent::schedule_reboot_ ( )

Communication with the sensor is asynchronous.

We send requests and let esphome continue doing its thing. Once we have received a complete line, we process it.

Catching communication failures is done in two layers:

  1. We check if all requested data has been received before we send out the next request. If data keeps missing, we escalate.
  2. Request the sensor to reboot. We retry based on a timeout. If the sensor does not respond after several boot attempts, we give up.
