Kostal Piko JSON Flow

Simple flow to query Kostal Piko Inverter using DxS

Supported Inverters

All Kostal Piko and Piko BA Inverters with UI Version >= 6.00 are supported. To doublecheck if your own inverter is supported do a HTTP-Request and check for a valid JSON Response:

http://{IP-Adress}}/api/dxs.json?dxsEntries=16777984

Response should provide Inverter Name and some additional stuff:

``
{
"dxsEntries":[
{
"dxsId":16777984,
"value":"YOUR INVERTER NAME"
}
],
"session":{
"sessionId":0,
"roleId":0
},
"status":{
"code":0
}
}
`

$3

- add node to flow
- set inverter ip
- use trigger node with any payload as input to trigger query to inverter (e.g. every 10 secs)
- use payload in your flows

Values

- INVERTER_NAME: Name of inverter
- INVERTER_SERIALNUMBER: Serialnumber of inverter
- YIELD_TOTAL: Total yield in kWh
- FEED_IN_STATUS: Is inverter feeding into grid
- HOME_CONSUMPTION_PV: current consumption directly from pv in W
- HOME_CONSUMPTION_BATTERY: current consumption directly from battery in W
- HOME_CONSUMPTION_GRID: current consumption directly from grid in W
- HOME_CONSUMPTION_TOTAL: overall Home consumption in kWh
- HOME_CONSUMPTION_DAY: todays overall home consomption in Wh
- FEED_IN_TIME: overall feed-in time in minutes
- AUTONOMY_DEGREE_DAY: todays grade of autarky in percentage
- OWN_CONSUMPTION_RATE_TOTAL: total rate of own consumption in percentage
- AUTONOMY_DEGREE_TOTAL: total grade of autarky in percentage
- HOME_TOTAL_POWER: current overall consumption in W
- BATTERY_SOC: current state of charge of battery in percentage
- BATTERY_ABSOLUTE_CURRENT: current current (lol) of battery without direction (absolute value)
- BATTERY_CURRENTDIRECTION: if value > 0: battery is discharging // if value <= 0: battery is charging
- YIELD_DAY: daily yield in kWh
- AC_P_TOTAL: current total available power of ac-side (includes any possible consumption except for battery charging since this happens on dc-side). great value to find out how much power is available for devices like washing machine etc at home. calculate like that: *available power = AC_P_TOTAL - HOME_CONSUMPTION_PV - HOME_CONSUMPTION_BATTERY
- COSINUS_PHI: cos phi of grid
- OWN_CONSUMPTION_TOTAL: overall own consumption in kWh
- OWN_CONSUMPTION_DAY: own consumption of day in kWh
- OWN_CONSUMPTION_RATE_DAY: own consumption rate in percentage
- INVERTER_OPERATING_STATUS: current status of inverter as localized string
- HOME_OWN_CONSUMPTION_TOTAL: total home own consumption
- GRID_FREQUENZY: grid frequency in Hz
- DC_I: current overall current of dc strings
- DC_P: current overall power of dc strings

Feel free to contact me: Patrick Moldenhauer . Note that this Node is in very alpha version and could be much better for sure. Anyway - this node should work quite stable and is very fast too since DxS Endpoint can be queried quite frequently without bothering inverters comm-board too much.
