Environment sensor that is powered by a 18650 battery using a dht22 to sense temperature and humidity. Connectivity is provided wireless using an esp12 sleeping deeply most of the time.

The connection between GPIO16 and RST to wake up the ESP8266 from deep sleep is missing. See this tutorial or the arduino core reference for details.
The DHT22 needs at least 3.3V to work properly. Maybe it should be connected directly to the battery. Data pin might need to be level shifted then.
change battery holder to one without cables that can be soldered
