Events: State node not updating when state changes quickly
Describe the bug
I set up a events: state node to track a media player entity and detect when it is off for 30s. This entity has several states and often go very quickly through playing -> idle -> off (when I turn it off without pausing first, which happens all the time).
When this happens, the node gets stuck on detecting the idle state.
To Reproduce
This flow triggers the behavior every time (when the events: state node is freshly created).
When triggering the on/off rapid change, the node gets stuck on on as in the picture. If I modify the node (eg. adding one second to the condition timer) the problem seems to disappear.
Expected behavior
The events: state node should update with every new entity state, it should not get stuck on a previous spurious state.

Environment Information

Home Assistant version: 2024.10.2 Companion version: 4.1.1
Node-RED version: 4.0.5 Docker: yes Add-on: no
Node.js version: v18.20.4 x64 linux OS: Linux 6.1.0-23-amd64 x64
Additional context
No response
Is the state change being detected by Home Assistant from the media player? You can confirm this by listening for the state_changed event in Home Assistant:
- Go to Developer Tools > Events.
- Under Listen to events, type
state_changedand click Start Listening.
You can also verify this in Node-RED by using an events: all node to see if the event is being picked up there as well.
I can see the event is detected by Home Assistant in the developer tools, the events: all node catches it, as well as the events: state if I remove the timed condition.
The only way to reproduce seems to be by adding a timed condition on the events: state node
When the 'for' condition is set in the events: state node, the entity's state must remain unchanged for the specified duration. Since you're mentioning the state changes rapidly and within the 4-second window, it won't capture the intermediate states.
As I understand it, the node's output is triggered if the state matches the required state during the given period, so it doesn't matter if the state changes from an unmatched state to a matched state within this period, does it?
For example, if I set the node to wait for the entity to be in state1 during 30s I'm expecting the node to:
- output something if the entity goes rapidly through
anything->state2->state1then stays instate1during 30s - output nothing if the entity goes rapidly through
anything->state1->state2(as it will stay less than 30s in thestate1state)
Am I understanding it wrong?
