How can I reduce the energy consumption of WiFi and MQTT?
Hello guys , I'm working on developing an IoT temperature and humidity sensor for my cellar. I'm using NodeMCU ESP8266. I'm sending the information to an MQTT broker.
The battery (18650 3.7V 19800mAh Li-ion rechargeable lithium batteries)

How can I reduce the energy consumption of WiFi and MQTT? Is there a way to achieve low power consumption?
Thank you.

Solution
WiFi is a massive power drain. You may want to investigate something like LoRa https://en.wikipedia.org/wiki/LoRa which has a long range and lower power consumption.
LoRa (from "long range") is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo, a company of Grenoble, France, and patented in 2014. Cycleo was later acquired by Semtech.
