Plugin should work with any Meter (electric, heat, gas, water), supporting OBIS codes via RS485 or RS232

Tested on the Energy Meter Elster A1500

Example LUA CODE:

Code: Select all

commandArray = {}

print ("P1 Meter");

SYSTEM_MULTIPLIER=1600

-- 1-1:1.7.0(0.467*kW)
POWER=otherdevices_svalues['A1500.Obis.Codes - 1-1:1.7.0']
POWER=POWER*SYSTEM_MULTIPLIER*1000

-- Obis 1-1:1.8.0(03388.522*kWh)
USAGE=otherdevices_svalues['A1500.Obis.Codes - 1-1:1.8.0']
USAGE=USAGE*SYSTEM_MULTIPLIER*1000

-- commandArray['UpdateDevice']= not working with influx
-- commandArray['UpdateDevice']='211|0|'..USAGE..';0;0;0;'..POWER..';0'
URLJSON="/usr/bin/curl -m 2 'http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=211&nvalue=0&svalue="..USAGE..";0;0;0;"..POWER..";0'"
os.execute(URLJSON);

return commandArray
