Esphome when using deep sleep,No network found

ESPHome

Good day, I found a very strange behavior, esphome when using deep sleep. if at the time when woke up esp, the wifi router is not available. esp will not fall asleep again. I get the following in the log:
[12:57:27] [D] [wifi: 304]: Starting scan …
[12:57:29] [D] [wifi: 319]: Found networks:
[12:57:29] [D] [wifi: 321]: No network found!
[12:57:29] [W] [wifi: 488]: Restarting WiFi adapter …

The electricity was turned off tonight and my battery-powered wifi thermometer completely went bad.
Maybe someone knows how to tell esp that if within 10 seconds (maybe 5 seconds) wifi is not detected, then you need to go to sleep.

reboot_timeout ( Optional , time): The amount of time to wait before rebooting when no WiFi connection exists. Can be disabled by setting this to 0s , but note that the low level IP stack currently seems to have issues with WiFi where a full reboot is required to get the interface back working. Defaults to 15min .

Thanks for the answer. This is what mi need.
I can’t find information here whether it is possible to wake up the ESP without turning on wifi, check the temperature, compare it with the previous one and if, for example, it changes by 0.5 degrees, turn on wifi and send information. if not, save to RTC

No esphome will not run without a wifi connection.

It didn’t help, the same problem if I turn off the mosquito, I get
[22:00:06] [I] [mqtt: 162]: Connecting to MQTT …
[22:00:06] [W] [mqtt: 247]: MQTT Disconnected: TCP disconnected.
Although I added

wifi:
  ssid: "vill"
  password: "***"
  manual_ip:
    static_ip: 192.168.1.2
    gateway: 192.168.1.1
    subnet: 255.255.255.0  
  reboot_timeout: 0s
  power_save_mode: HIGH
  fast_connect: ON

mqtt:
  broker: 192.168.1.5
  username: ***
  password: ***
  discovery: False
  discovery_retain: False
  reboot_timeout: 0s

This can’t be done because:

If it does not get a wifi connection no code is executed. Sleep can not be called.

then all the projects on the battery when you turn off the wifi router will constantly search for the network and as a result be rarefied?
This is somehow not logical.

You can make a feature request for the logic to be changed here:
