Thank you for instant reply.
I think my problem is the different view on that. Till now I thought those nodes are dedicated only for ability to control HA entities and feeding them with data. So they functionality is limited to:

creating/removing entities
setting its values with payload passed to input
optionally redirecting state changes to output

I cannot see why switch couldn’t work this way even if there are differences in communication with HA.

Switch functionality is pretty different having additionally built-in routing of all messages which hit input, not only those which caused its state change. To me it seems that it duplicates the functionality of current state node, isn’t it?
Anyway seems that this feature led to a need of moving control messages to msg.enable instead of payload.
Then if I want to follow control messages only, I have to join both outputs (also change/hardcode values because currently the node doesn’t output its state), and filter-out other messages which possibly come to the input.

Actually it doesn’t work if I want to intercept switch state change caused by the flow. Something I can achieve with binary_sensor type of entity node as for example

It all seems cumbersome to me;

But if this behaviour is intentional and someone feels it’s useful then I have to accept that as a feature and live with it.

thank you for your work. I really enjoy playing with NR, which wouldn’t be possible without your contribution.

@Kermit may i ask some help? im trying to compare climate max temp with current temp via current state node

$entity().state > $entities("sensor.tempmax_" & topic).state

edit:
probably need to cast them to numbers

$number($entity().state) > $number($entities("sensor.tempmax_" & topic).state)

Love this implementation a lot

I am using node ha-entity to create and update sensor value.

I can not figure out, how to handle updates if the sensor repeats the previous value. When checked in HA, it shows as not being updated since the last state change.
I guess somehow I’d need to touch last_changed…

Here is my flow:

Is this correct approach, or should I do it differently?

Kermit · February 8, 2021, 9:15pm

Currently, there is no “force_update” on the NR entity node.

You can fake it by adding another attribute to the entity that could be named anything with the value as timestamp.

Joc · February 9, 2021, 5:25pm

Thanks for reply. Unfortunately, this didn’t do the trick.
Screenshot_1

I added attribute updated, assigned it to timestamp and it is indeed changing, however, since the temperature value doesn’t change, it’s reporting as “dead sensor”.

Perhaps I’d need to rethink the whole concept. Any ideas, how to approach this?

rchl · March 7, 2021, 11:43am

I’ve gotten the new Philips Hue Dimmer Switch that has a Power button instead of On/Off buttons so I want to create a logic for toggling the lights using just one button. The button has to toggle two (or more) lights so the logic can’t be as simple as using “homeassistant.toggle”.

The logic should be:

if any light is on then the Power button turns off all of them
if none of the lights are on then the Power button turns on all of them

For implementing that I would need to get the state of all related lights and based on their ON/OFF states determine what to do.

I wonder if anyone has suggestions on how to do that. It seems like the “Current state” node can only get the state of one entity so that seems the biggest blocker for me.

Once I get the state I guess I can write some custom JS logic using the “Function” node since I don’t think this addon has anything so specific to my use case.

Kermit · March 8, 2021, 1:40am

Use a HA group with all the lights. If it’s on there’s at least one light on the group is on and if they are all off the group is off

rchl · March 13, 2021, 11:03am

Thanks. That would work nicely but I want to depend as little as possible on HA configuration in NodeRed so as to not have to maintain two moving pieces at the same time.

I’ve implemented that using the “Get entities” node (apparently it can get states of multiple entities using regexp) + a custom function node that returns a payload formatted for the “Call service” node.

Sammerdan · March 13, 2021, 7:03pm

Hi,

I’ve just posted this topic about a problem with the service homeassistant set_location which is demanding a lot of memory (until my Pi freezes).

I’m just linking from here, since I’ve got the feeling people are reading here, who can help me out.

Thanks!

Hi,

I’ve a problem with using global variable in render template node.
This example doesn’t work:

Help, plz.

b3nj1 · March 17, 2021, 3:56pm

Hi,
The home-assistant template doesn’t see node-red scoped variables. You can get around this by stringing together a node-red template then a home-assistant template. Here’s your example with an additional node-red template node. The node-red template makes a string that will be expanded by the home-assistant template, so 1. I had to change the delimiter so that the {{ }}'s were preserved in the output, 2. I added a home-assistant variable to expand (assuming you have a sun sensor).

Firstly, thanks Kermit for all your hard work on this, really appreciated.

Can anyone point me to some instructions on using the trigger-state node? I thought I had it figured out, but no matter what I try I keep messing it up, so I feel I need some ELI5 explanation and my Google searches have failed me.

I’m just trying to test it out with something simple where when a light in my office is turned on it outputs a custom boolean message of true, as below. Sadly the debug shows multiple lines of the state of the office light, not the true message I was expecting. I’m sure I’m doing something wrong and that it’s dead simple but I just can’t figure it out.

I have been attempting to migrate my automations to Node Red and have run into a bit of a snag. Some of my existing (non-NR) automations permit me to enable / disable them from the lovelace UI. I would like this functionality while using NR and apparently this thread indicates that this IS possible. Unfortunatly I am unable to get this to work. My NR is running in a docker container, My HA is also running Core in docker. I have created the Long lived access token in NR, and NR is controlling my devices when I create flows. I have installed the Node-red-contrib-home-assistant-websocket, I have installed the HACS Node-Red Companion, and I have installed the Node Red-Companion integration. My NR can see all my HA entities but I am not seeing any NR entities begin created in HA that I can enable / disable my flows. Am I missing something?

Kermit · April 27, 2021, 1:16am

When you edit an event node towards the bottom of the config window should be Expose to Home Assistant

pcwii · April 27, 2021, 1:29pm

I am sure I did not see that before you posted. Maybe a reset or re-creating the access token revealed it. Thanks

Thanks for your work on this great set of nodes. A feature that I’d like to request (if not possible yet already) to help make my system a bit more stable: monitor if NR loses the connection to HA, and be able to us that info in a sequence.
