Hello, I have some suggestions on how to reduce your power rate on you DIY project.

1. Use static IP it will reduce time of new connection to router after wakeup.
   For example:
   #define ssid "kibab"
   #define password "0612748587"
   #define DHCP true
   IPAddress local_IP(192, 168, 0, 61);
   IPAddress gateway(192, 168, 0, 1);
   IPAddress subnet(255, 255, 255, 0);
   IPAddress primaryDNS(192, 168, 0, 1);
   IPAddress secondaryDNS(8, 8, 4, 4);
   #define chanal 6 //wifi channel
   byte macAP[6] = {0xF8, 0x1A, 0x67, 0x86, 0x14, 0x70}; //router mac

2. On ESP you can use several SLEEP-modes
   modem-sleep
   light-sleep
   deep-sleep (you should try this one)
   There is a good article on this topic https://smartideal.net/kak-ispolzovat-deep-sleep-na-esp8266-nodemcu/
   NB: Notice, that you can push your device to sleep mode without disconnecting and turning your WIFI off.

3. BME280 - you should put it on sleep too (power mode - sleep)
