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 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
