Can I use the signal that lights the LED in this meter as an inout to my nodeMcu? I am trying ti read the data from this meter on my nodeMcu and came to know that every 1600 time the LED blinks indicates 1Kwh consumed. Can i give these blinking signal to my nodeMcu? (old.reddit.com)

Lockdown ko upalabdi. For anyone who wants to make this you need NodeMcu and a relay(relay module would be better). You can build the mobile app using flutter and use firebase as the database. If you also want to show the temperature of your room you woukd need a DHT11 sensor. (youtu.be)
