-===== Programmierung =====
+===== Programming (ESPEasy)=====
 After the hardware has been created, we still have to program the ESP module. As already mentioned, the PowerMeter is based on [[https://www.letscontrolit.com/wiki/index.php/ESPEasy|ESPEasy]]. In the link you can also find instructions on how the ESPEasy firmware is installed on the module. In order to get into the programming mode, the jumper SJ1 must be closed during the reset release. The programming is done serially via JP1 (USB-serial converter).

 The calculated result is sent to the MQTT server at each completed measurement interval.
+===== Programming (ESPHome)=====
+The PowerMeter can also easily be integrated with help of [[https://esphome.io|ESPHome]] into [[https://www.home-assistant.io|Home Assistant]]. The sample code for one phase you will find here:
+<code yaml>
+esphome:
+  name: powermeter
+esp8266:
+  board: esp01_1m
+# Enable logging

+# Enable Home Assistant API

+  - platform: total_daily_energy
+    name: "Total Daily Energy"
+    power_id: powermeter_flat
+</code>
+Instead of measuring the time between two pulses the number of pulse per time interval is counted.
 ===== Conclusion =====
-The PowerMeter has been running for 2 months without any problems and is transmitting the data. A typical consumption curve looks like this (screen shot from my own //Volkszähler//):
