Parameters

NameDescriptionValueLevel
hostIP address or hostname
Example: 192.0.2.2
optional
portPort
Default: 8899
optional
capacity [kWh]Battery capacity
Example: 50
optional
minsoc [%]Minimum charge

Lower limit as configured on the battery system. Used by optimizer.

Default: 7
Example: 25
optional
maxsoc [%]Maximum charge

Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging.

Default: 97
Example: 95
optional
capacity2 [kWh]Battery capacity of the second battery
Example: 50
optional
maxacpower [W]Maximum AC power of the hybrid inverter
Default: 0
Example: 5000
advanced
externalpowerExternal power

Query external power of all devices connected to S0

advanced
maxchargepower [W]Maximum charge power

Highest power the battery system can charge with. The optimizer plans with charging up to this power. Some devices also use it as grid charging power.

advanced
maxdischargepower [W]Maximum discharge power

Highest power the battery system can discharge with. The optimizer plans with discharging up to this power. Smart mode assumes the battery supplies at most this power to vehicle charging.

advanced
cacheCache

Time interval for data refresh

Default: 30s
Example: 5m
