First steps with emonESP

[glyn.hudson]

You need to connect UART Tx from your sensor to UART Rx on the ESP. See our example connecting emonTx V3 to ESP:

Using the EmonTx v3 with the ESP8266 Huzzah WIFI module

Following on from the forum post here ESP8266 Wifi Developments. This is a brief guide on how to use the Adafruit ESP8266 Huzzah WIFI breakout module with an EmonTx v3 to make a simple WIFI enabled energy monitor that posts to a remote emoncms server such as emoncms.org. Note: this is an ongoing development project, but is a useful option in its present form [image] In the future, we may integrate the ESP8266 module directly on the EmonTx PCB. For now, the ESP8266 Huzzah module provides a go…

There is examples of how to serial print serial:strings in the latest emonTx and EmonTH code e.g.:

    Serial.print("ct1:"); Serial.print(emontx.power1);
    Serial.print(",ct2:"); Serial.print(emontx.power2);
    Serial.print(",ct3:"); Serial.print(emontx.power3);
    Serial.print(",ct4:"); Serial.print(emontx.power4);
    Serial.print(",vrms:"); Serial.print(emontx.Vrms);
    Serial.print(",pulse:"); Serial.print(emontx.pulseCount);
    Serial.println("");
