P3 Energy Display Met NTP klok !

Matrix display met P1 meter gegevens : Injectie, verbruik.

Batterij gegevens : Spanning, Soc en Power !

11 03 2023 Update van het project, klok toegevoegd en ook case in 3D iets aangepast.

Zorg natuurlijk eerst voor dat je de volgende projecten reeds gemaakt hebt !!

Slimme Meter Uitlezen

Top BMS to ESP32 Oled and Domoticz

En natuurlijk ook je RaspberryPi met Domoticz en NodeRed !

De Code !

Bibliotheken die we nodig hebben.

#include <PxMatrix.h>#include "Arduino.h"#include <ESP8266WiFi.h>#include "EspMQTTClient.h"#include <Adafruit_GFX.h>#include <Ticker.h>

Hier je eigen setting instellen van netwerk en broker !

EspMQTTClient client( "xxxxx", // your SSID "xxxxxxx", // Your network pasword "192.168.1.19", // MQTT Broker server ip "spike", // MQTT Broker users Can be omitted if not needed "1234", // MQTT Broker pasword Can be omitted if not needed "P3", // Client name that uniquely identify your device 1883 // The MQTT port, default to 1883. this line can be omitted);

NODE RED DATA

De Client.Subscribe moet overeenkomen met de instellingen in NodeRed

void onConnectionEstablished(){ client.subscribe("p3/injectie", [](const String & payload) { sprintf(curMessage, payload.c_str()); }); client.subscribe("p3/verbruik", [](const String & payload) { sprintf(curMessage1, payload.c_str()); }); client.subscribe("p3/soc", [](const String & payload) { sprintf(curMessage2, payload.c_str()); }); client.subscribe("p3/battpower", [](const String & payload) { sprintf(curMessage3, payload.c_str()); }); }

Code om een waarde weer te geven

display.setFont(&kongtext4pt7b); display.setTextColor(myRED); display.fillRect(0, 16, 31, 6, display.color565(00, 00, 0));display.setCursor(2, 21); display.print(curMessage1);

Bij elke tekst die we willen weergeven moeten we eerst een zware achtergrond maken om zo display telkens terug leeg te maken nadat de waardes veranderd worden, dit is een beperking in de Adafruit GFX lib.
