Can an Input Boolean be replaced by a function?

Third party integrations Node-RED
1

The more I learn about node red the more I realise how powerful it is. And the more I can do without going back and forth between nr and hassio I feel the better (and cleaner) it all is.

I was looking at a post about motion overriding a light switch.

https://community.home-assistant.io/t/light-with-motion-override-with-switch/62575

But for this to work there are a collection of input Boolean switches that just record a state for a trigger. I was thinking, could this be done via a function.

I believe I have the framework, just not the coding skills yet.

Could it be possible rather than sending a call service to HA to switch an input Boolean switch to be a flow wide variable that can be recalled and acted upon as in the link above?

Basic motion sensor turns light on and off on the right with a trigger node. The left watches for a state change of the light and checks if the context.user_id is null which normally means that the device changed state without Home Assistant acting on it. Which then disables/enables, depending on the state of the light, the trigger-state node and resets the trigger node if it has an active timer.

I can see the brilliance in this. I have been trying to understand state triggers better. This is just so clever.

Unfortunately, it did not work. I think the user_id null is not working as intended. It took me a while to try and have the flow in a state where it would work, but as soon as there is motion it disables the motion sensor.

Just doing some isolation testes.

First and second message data is from a manual switch.

third and forth is from switching it on from Homeassistant.

Not have the userid component.

This is with a Current state node and a manual switch

And last test. Using Home Assistant to trigger the light.

Hass the user_id as Null

Yea, I see the error I made with the user_id is null switch by sending a custom message it’s not passing on the other message data. You can fix this by changing the first custom output to the example below:

Then you can add a change node after the switch with the reset command

So it ends up looking something like

As far as user_id being null for everything. Do you run home assistant with a trusted network or something where you don’t log into the web ui?

I got it close to 100%. The user ID is now correctly reporting as Null if I manually trigger the light… Well not always.

After the motion trigger event has switched my light off the next (only) manual on will send a user_id, a manual off then on will set it back to null, however.

Off message sent

The next trigger is manual from the switch. It shows a User ID

I can turn the light manually off then back on and its sends user ID as Null.

I wonder if I can sell that to my wife as a user feature?

11

I just tested it with another light. I assume I have done something wrong, but the manual switch often sends a user ID. And sometimes it does not.

Any suggestions on my error?

This is another way I tackled the issue

I changed the TASMOTA switchmode to 2 and gave a custom topic. I have node red watching the topic that will then turn the light on or off via MQTT. But I am able to disable the automation with this method.

This is version one. I need to get the physical and virtual switch into sync. But its a start.

@Kermit It has been some time but I may have stumbled onto a breakthrough. My issue above was HA not recognizing the Null user ID for turning on/off a physical switch.

I was converting my Sonoff switches to ESPhome and the code I was using used both a Physical and a HA toggle switch.

I was wondering if you could guide me in the above flow to enable the motion trigger is disabled if the physical switch has been used. For your refrence, I have included the yaml for ESPhome that shows the two switches.

Thanks

@Kermit - I feel like this was working for me just a few minutes ago but this morning its not… every time the motion automation triggers the flow I end up w/ the motion sensor being disabled… i tried to impliment this update but I’m having trouble still… Any change you can post a working example from you flows?
