This is live electricity usage/generated data from my home. If the usage is zero it's because the solar panels are covering the load. :)

I am building many sensors using nodemcu and lua trying to connect everything together.. Have a look at my other thingspeak pages: https://thingspeak.com/channels/145827

My Smart Fridge on ESP8266 with simple energy (wattage) metering, Kharkiv, Ukraine

Methane Gas Sensor MQ-5 & Temperature, Kharkiv, Ukraine

Currently, this Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.

Air Quality Sensor with ESP8266 and Si7021 and MQ135 for CO2

NodeMCU

NodeMCU (programmed with Arduino sketch) & DHT22 (AM2302)

Temperature & humidity gathered using NodeMCU & DHT22module

Nodemcu (ESP8266) + 5 x DS1820 on my hot water tank, ready for control of the heating elements, with auto-update of software, code on github (not my video)

Home temperature, relative humidity and light measurement test using an ESP8266 with DHT11 and a photoresistor. LUA only, with NodeMCU firmware. The video channel is not mine, but interesting. Click on 'More Information" :-)
