|
|
Simple node for push/pull operation of StackItems from chests or other
|
||
|
|
inventory/server nodes to tubes or other inventory/server nodes.
|
||
|
|
|

|

The Pusher is based on the class NodeStates and supports the following messages:
|

|
|
- topic = "on", payload = nil
|

|
|
- topic = "off", payload = nil
|
||
|
|
- topic = "state", payload = nil,
|
||
|
|
response is "running", "stopped", "standby", "blocked", or "not supported"
