Hallo zusammen folgende Idee,
ich möchte gerne meinen Growatt direkt in VenusOS einbinden.
Aktuell bin ich soweit.
auf dem Modstick ist ESPhome und liest die Daten aus und sendet sie per MQTT an eine andere Steuerung. Bei mir IoBroker.

devicename: "esphome-growatt-01"

Die Ausgangsleistung des PV WR kann im Browser oder per mqtt geregelt werden.
Auf dem venus OS läuft ein mqtt treiber
https://github.com/mr-manuel/venus-os_dbus-mqtt-pv
Im IoBroker werden per Node Red die Werte an den Treiber geschickt. folgende Form hat das Json
msg.payload = {
"pv": {
"power": msg.payload["P"],
"voltage": msg.payload["V"],
"current": msg.payload["I"],
"energy_forward": msg.payload["W"],
"L1": {
"power": msg.payload["P"],
"voltage": msg.payload["V"],
"current": msg.payload["I"],
"energy_forward": msg.payload["W"],
}
}
Idee diee werte direkt von dem Modstick per mqtt ans Venus senden.
geänderter Code noch nicht getestet
- platform: modbus_controller
name: "${devicename} AcPower"
id: pv_power
address: 40
register_type: "read"
unit_of_measurement: W
device_class: power
icon: mdi:flash
value_type: U_DWORD
accuracy_decimals: 1
filters:
- multiply: 0.1
on_value:
- mqtt.publish_json:
topic: "Growatt/mic2000/meters"
payload: |-
return {"pv": {
power": id(pv_power).state,
"voltage": id(pv_voltage).state,
"current": id(pv_current).state,
"energy_forward": id(pv_energy_forward).state,
"L1": {
"power": id(pv_power).state,
"voltage": id(pv_voltage).state,
"current": id(pv_current).state,
"energy_forward": id(pv_energy_forward).state,
}
}};
Evtl. sieht ja jemand ob der code einen Fehler hat ich komme erst morgen zum testen und bin relativ neu in esphome.
