Hello, I have simple PIR sensor that turns power on ESP8266 and sends mqtt state “on”. Then it cuts off power to ESP, so in Home Assistant it becomes “unavailable” after some time. But I would prefer to show sensor state as “off”, because in this case unavailable means “off”. How the sensor would be configured in configuration.yaml please? It is simplest PIR sensor - just to connect ESP power to PIR out pin. Thank you!
