ESPhome and deep sleep

ESPHome
11

@moci and @tom_l You could actually use this method…

Set up a ESP like this (code below) and it will subscribe to the message on the MQTT server, se it when it wakes up and take that value and set it to be the deep sleep duration value. Make sure the value you are sending as the topic however is in milliseconds.

I believe this call:

    on_value:
      then:
       - lambda: |-
          id(deep_sleep_1).set_sleep_duration(id(custom_sleep_time).state);

is not is not documented but it works fine for me :).
