The JsonLogic-Controller is a very generic Controller that allows the definition of a complex logic as a configuration at runtime, e.g. via Apache Felix Web Console.
It is based on the JsonLogic specification (jsonlogic.com). Logics can be defined by a rule:
{
"if":[
{
"<":[
{
"var":"_sum/EssSoc"
},
50
]
},
[
[
"ess0/SetActivePowerEquals",
5000
]
],
[
[
"ess0/SetActivePowerEquals",
-2000
]
]
]
}The input data that is referenced via var is automatically provided from OpenEMS Channels - e.g. as
{
"_sum/EssSoc": 40
}This example would result in:
[
"ess0/SetActivePowerEquals",
5000
]i.e. the Controller will require a set-point of 5000 W discharge on ess0.
It is also possible to write to multiple channels, by adding more arrays to the result.
