Should UI switches reflect changes made in node-red-dashboard?

[Dave B]

I'm not sure if I'm in the right spot but if not, can you kindly point me there?

If an input is changed from high to low either by injecting a 0 or 1 to a digital switch or via some other event which sends a high/low signal it does not show within the UI that the switch has been moved high or low.  Is this a default behavior or am I missing something?  I'm very new to node-red and perhaps I'm doing something wrong or there is a better way to have some indication in the UI what the switch status is.  I've included an image to clarify what I'm asking.

Thanks much,

Dave

  I should note the switch not changing states is the UI switch NOT the one in the node display.  

Isn't there a way to edit a post in google groups??

Thanks much,

Dave

You need to check to see how you've configured the switch, as if you send the switch the same payload as it is configured to send it should work.

I've just tested it with a switch set to send a boolean True or False and with two inject nodes set to the same and the dashboard displayed switch state is changing for me.

What payload type and values are coming from the Schedule and what
have you specified for the switch on/off values? Make sure they match
exactly.

No, this is a mailing list. You can't edit it once it is in my inbox.

Just to clarify, the Google Groups UI does allow you to edit posts so when someone browses the group at https://groups.google.com/group/node-red they will see your edited post. However, as Colin says, most people receive posts via email so will not be aware of your edits.

I can't see how to do that, can you describe how please?

Huh, I take it back. I thought there was an edit option - but I was mistaken. You can delete posts, which obviously doesn't delete them from people's inboxes, but you cannot edit.

It's a relay so on payload is 0 and off is 1.  If i manually add 1/0 injects to the below node it works fine however for some reason using the schedex (even though it is sending 0/1 it doesn't change the UI switch.  Maybe you can see if I am missing something?  (Day 2 of Pi)

[Dave B]

ok so riddle me this.  I checked the debug node out of the schedex and it does not output anything.  How can it send a payload to the relay to actually turn it on/off if it isn't sending some payload?  I assume that is why the switch isn't changing but how the heck is the relay turning on if it isn't getting a payload?

Sorry to clutter this up (I hate not being able to edit) I'm an idiot. I had the debug switch OFF it is obviously sending a payload of 0 or 1 as it should yet the UI switch still does not reflect said change.

If I look at your switch node you have this (see image) where one is a string and one is a number

To avoid issues later you need to be aware of the data type of the string. see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures

 

[Dave B]

Yeah I was experimenting by changing between number/payload.  I'm still trying to grasp the differences here but that'll come in time.

I’m really learning a ton here.  It turns out this particular node uses on/off.  So that leaves me with two questions.

 

1.       Is this typical?  Perhaps I missed some doc somewhere that ID'd the payload input/ouput (The info tab and readme.md for this file didn’t mention this) so I made the mistake in assuming that 0/1 would be the output but the more I think about it, this has to be a versitile thing so on/off is probably easiest.

 

2.      Aside from a change node to change 0 to on and 1 to off, is there an easy way to change the payload from on/off to 0/1?

Thanks a ton guys!!

It is not only whether it is 0/1 or on/off, but whether it is the
numbers 0 and 1 or the string "0" and "1". 0 is not the same as "0".
I suggest you decide what you want to use for such values and stick
with that throughout your whole system. I would be interested in
knowing what the consensus of opinion is as to which is preferable.

As to how to change one value to another you can use the Change node to do that.

Thanks Colin.  I guess my next question would be how do I know if the output is a string or a number if the actual character will look the same?  All things being equal would a number and a string output of 0 be the same for all intents and purposes?

Thanks

In the debug display it tells you the type. If you are generating it
yourself you should be able to define it. If it is coming from another
node then the node documentation should make it clear.

Good question Colin.

I tend to use On/Off. I think that comes mainly from the tentative early steps with sensors using things like LightwaveRF and other home automation systems. Also, it is a little more clear, I personally think, as to whether you are receiving valid data or not.0/1 or true/false are too easily misinterpreted.

I do like on/off also as sometimes 0/1 don't represent on/off the same.  IE I have some relays that need a low input whereas others need a high input so 0 would be on for one but off for the other.  So my question again would be, when given a preconfigured node module (I don't know the technical term) how do you know if the output is a number or a string?

[Dave B]

NM, see the debug area where it states number/string.

If it is not clear from the documentation of the node then attach a
Debug node to it and see what it says. With the debug node set to show
(for example) msg.payload then the first line of the output tells you
the type. For example it may say something like "msg : string [32]"
meaning that it is a 32 character string.
