Hi everyone,
I recently started using a little bit more Node-RED in my HA, and stumbled upon a problem that I couldn’t solve with a simple google search so here I am:
I am trying to set up a ‘delay node’ that will be controlled via Lovelace via home assistant helpers. I have set up an automation helper called “Fan duration” and I can read its values in node-red via state changed node. My main automation is a simple action that starts a fan every two hours and then turns it off after 30 seconds. I want to customize those 30 seconds to be easily changeable via lovelace.
Current situation: Main loop works well, the fan starts every 2 hours and turns off after 30 seconds. Changing the state of “fan duration” results in sending a msg.delay to delay node and an expected delay of X seconds.
Two issues here:
- The delay node starts upon receiving the msg.delay - it should only start upon receiving the signal from the ‘main loop’ / ‘store’ the value from state changed node
- The supplied msg.delay isn’t taken into account when delay node is triggered via the ‘svc: switch:turn_on’ aka the main loop and uses the default 30 seconds
Here is my flow:

Sorry if this is a basic question, I just can’t figure this out and would appreciate some pointers. Thank you!
