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

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. :)

Air Quality Sensor with ESP8266 and Si7021 and MQ135 for CO2

This channel implements a Telecontrol project. There are fields for temperature measurement, and two fields to store the status of two channels controlled via Talkback. The APP read the values of the channels fields, to assure that the command has been

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" :-)
