Reduce power consumption ESP8266

[Uhwah]

Describe the problem you have/What new integration you would like

I did various tests with ESPHome and Tasmota. I noticed that ESPHome doesn't seem to have any power saving functions (except Deep Sleep). Tasmota has a feature called Dynamic Sleep. My measurements have shown that an ESP8266 with a DS18b20 sensor under ESPHome has 2.4 times the power consumption compared to Tasmota. The whole thing also causes the ESP8266 to become noticeably warm under ESPHome, which in my opinion can influence temperature measurements. **Please describe your use case for this integration and alternatives you've tried:** Reducing power consumption should always be a high priority these days. **Additional context**

This is most likely not a problem with power saving functions, but floating GPIO power draw. PTAL https://github.com/esphome/feature-requests/issues/2587

I changed all GPIO pins as described. (GPIO 16 was prevented with an error message)-> GPIO Pin 16 does not support pullup pin mode. Please choose another pin. Unfortunately nothing has changed.
The ESP01s consistently requires 0.05A even though the sensor query takes 60s (averaged 0,255W). With Tasmota I can see how the consumption fluctuates with a maximum of 0.05A (averaged 0,106W).

GPIO16 supports pull-down. But if it doesn't help, then it might be a different problem.

The ESP01s consistently requires 0.05A even though the sensor query takes 60s (averaged 0,255W). With Tasmota I can see how the consumption fluctuates with a maximum of 0.05A (averaged 0,106W).

so there is this option in esphome https://esphome.io/components/wifi.html#wifi-power-save-mode which i do not see in your script, but I know tasmota has a different default here and therefor by default consumes less energy

That was the right hint! Now the value is very close to the value of Tasmota. Many thanks for the help.
