Hi!
I am trying to create a flow that prevents me from arming the alarm if any door is open at that time. It is part of a much bigger project im working on to make a "decently"-fledged security system.
Here is an overview of the whole thing:
So you will understand why I don't share the JSON for the entire flow.
I am interested in this section in particular:
[{"id":"d1309cd8.eb7a1","type":"switch","z":"b0e56e3d.dcc36","name":"Arm Alarm?","property":"topic","propertyType":"msg","rules":[{"t":"eq","v":"input_boolean.alarm_home","vt":"str"},{"t":"else"}],"checkall":"true","repair":false,"outputs":2,"x":320,"y":100,"wires":[["1bd5bf39.e28bb1"],["f600e5c5.bce7b8"]]},{"id":"10ca0ae8.314665","type":"api-call-service","z":"b0e56e3d.dcc36","name":"Disarm","server":"59c38194.90565","version":1,"debugenabled":false,"service_domain":"input_boolean","service":"turn_off","entityId":"input_boolean.dev_alarm_armed","data":"","dataType":"json","mergecontext":"","output_location":"","output_location_type":"none","mustacheAltTags":false,"x":660,"y":100,"wires":[[]]},{"id":"f600e5c5.bce7b8","type":"api-call-service","z":"b0e56e3d.dcc36","name":"Arm","server":"59c38194.90565","version":1,"debugenabled":false,"service_domain":"input_boolean","service":"turn_on","entityId":"input_boolean.dev_alarm_armed","data":"","dataType":"json","mergecontext":"","output_location":"","output_location_type":"none","mustacheAltTags":false,"x":650,"y":150,"wires":[[]]},{"id":"1bd5bf39.e28bb1","type":"api-call-service","z":"b0e56e3d.dcc36","name":"Reset Trigger","server":"59c38194.90565","version":1,"debugenabled":false,"service_domain":"input_boolean","service":"turn_off","entityId":"input_boolean.dev_alarm_triggered","data":"","dataType":"json","mergecontext":"","output_location":"","output_location_type":"none","mustacheAltTags":false,"x":510,"y":100,"wires":[["10ca0ae8.314665"]]},{"id":"59c38194.90565","type":"server","name":"Home Assistant","addon":true}]
I want to put a node between the "Arm Alarm?" switch and the "Arm" service call. Here:
Basically, what I would like to do in pseudocode is:
If any of [binary_sensor 1, 2 or 3] is open:
- Notify me via push
- Disarm
Else:
- Arm alarm
Now, I know how to do everything except for the IF part. So my question is:
- Is there any way to query the current state of an entity from within a function node?
- If not, is there any contrib node that lets me put multiple entity states in an AND or OR type?
- Or is the only way to either create a network of connected "current state" nodes to check each entity separately or writing each entity state into the flow context?
Thank you for enlightening me!
