Ok, habe es dann doch selber rausgefunden, es geht mit Adapter "simple RESTful API" und ein bisschen Code.
#!/usr/bin/env python3
import LCD1602
import time
import requests
def pollandwritedata():
api_url = "http://192.168.178.70:8087/getPlainValue/modbus.0.inputRegisters.5016_Total_DC_Power"
api_url2 = "http://192.168.178.70:8087/getPlainValue/modbus.0.inputRegisters.13009_Export_power"
api_url3 = "http://192.168.178.70:8087/getPlainValue/modbus.0.inputRegisters.13022_Battery_level_"
api_url4 = "http://192.168.178.70:8087/getPlainValue/modbus.0.inputRegisters.13007_Load_power_"
TDCP = 'I:'+str(requests.get(api_url).json())+'W'
EDCP = 'O:'+str(requests.get(api_url2).json())+'W'
BP = 'B:'+str(requests.get(api_url3).json())+'%'
LP = 'C:'+str(requests.get(api_url4).json())+'W'
# print(TDCP)
# print(EDCP)
# print(BP)
# print(LP)
LINE1 = TDCP+' '+BP
LINE2 = EDCP+' '+LP
LCD1602.write(0,0, LINE1)
LCD1602.write(0,1, LINE2)
def setup():
LCD1602.init(0x27, 1) # init(slave address, background light)
LCD1602.write(0, 0, '')
LCD1602.write(0, 1, '')
time.sleep(2)
def destroy():
LCD1602.clear()
if __name__ == "__main__":
try:
setup()
while(1):
pollandwritedata()
time.sleep(2)
destroy()
except KeyboardInterrupt:
destroy()
mit raspi-config muss natürlich der I2C vorher eingeschaltet werden.
