I need something like this. I need to set my charge value in a recipe window for the operational parameters of a device. I will have another button somewhere which sets multiple possibilities.

1. Set Auto or Single Shot mode
2. Start or Run
3. Validate ( Do not actually operate the device but validate the recipe and record the timing to accomplish the task.

I haven't tried to use the nodes to write a for loop yet, and need a little prod forward. I get the loop, but cant see how to get the ui\_numeric and the inject to work.

```auto

Sorry, but I can't make sense of it.

Could you please try to explain what you want to do?

In the flow you posted, I can't see an option to set "Auto" or "Single shot" modes.

What is it all doing?

What is `msg.i`  
What is `msg.items`  
What is `msg.items[msg.i]`

How are they _defined_?

How are they set?

It is all just a bit too vague.

I have a device. I need to open a valve a number of times. Say 50 times.

I want to use the ui\_numeric to set this value. wee will call this value charge.

I think it should be global.charge so that when I want to operate the device it will pull global.charge that has been set in the UI window

Here is the pump dashboard.

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/c/5c96ed324a3d8fe604afc8d881755bbcca6cc87e.jpeg)

Now I will have another operational tab the will have buttons to set globals as follows

Run \> run the Recipe  
Single mode \> run the recipe once  
Automatic mode \> run the recipe until you receive stop or error  
Validation \> Run the recipe but don't operate the device to validate the code loops and execution states.

Building the loops and getting the global variables set for the "Recipe" in node-red is a little confusing to me right now. I haven't done this before with the nodes. and I need a little help.

Here is the "Pump Recipe" tab and some stuff I'm playing with to figure it out.

But asking for help here to get going.

```auto
[{"id":"c3b01f99.76eae8","type":"change","z":"574cc1b.fd32a4","name":"","rules":[{"t":"set","p":"result","pt":"msg","to":"msg.result = msg.result + msg.payload","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":520,"y":340,"wires":[["6e0feac5.a472c4"]]}]

Yes, but it isn't passing correctly and I cant figure out how to tie in the loop. Any suggestions?

Getting the counter loop to work like the doc without it being an example is a guess at best for me.

Sorry, but I'm stuck.

A valve can only be `open` (on?) or `closed` (off)

Turning it on 50 times doesn't make sense.  
I can let that slide for the sake of the code, but it isn't helping me understand what and why you are doing it.

I'm reading the other posts now.

Here is a basic _loop_ flow.

It does 10 loops.

```auto
[{"id":"e83004c8.c06948","type":"switch","z":"b9924a74.4d98f8","name":"","property":"payload","propertyType":"msg","rules":[{"t":"eq","v":"0","vt":"num"},{"t":"else"}],"checkall":"true","repair":false,"outputs":2,"x":340,"y":3720,"wires":[["e02a58f5.04333"],["5d3aea5.d941b14"]]},{"id":"e02a58f5.04333","type":"debug","z":"b9924a74.4d98f8","name":"DONE","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":660,"y":3690,"wires":[]},{"id":"dadec0b0.6d204","type":"inject","z":"b9924a74.4d98f8","name":"","topic":"","payload":"10","payloadType":"num","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":190,"y":3720,"wires":[["e83004c8.c06948"]]},{"id":"5d3aea5.d941b14","type":"delay","z":"b9924a74.4d98f8","name":"Delay","pauseType":"delay","timeout":"0.5","timeoutUnits":"seconds","rate":"1","nbRateUnits":"1","rateUnits":"second","randomFirst":"1","randomLast":"5","randomUnits":"seconds","drop":false,"x":490,"y":3760,"wires":[["a7822d2e.f7db28"]]},{"id":"acf46b7a.f84c88","type":"link in","z":"b9924a74.4d98f8","name":"","links":["1e54624b.3b286e"],"x":225,"y":3760,"wires":[["e83004c8.c06948"]]},{"id":"a7822d2e.f7db28","type":"function","z":"b9924a74.4d98f8","name":"Step","func":"var x = msg.payload;\nx = x - 1;\nmsg.payload = x;\nreturn msg;","outputs":1,"noerr":0,"x":490,"y":3800,"wires":[["1e54624b.3b286e"]]},{"id":"1e54624b.3b286e","type":"link out","z":"b9924a74.4d98f8","name":"","links":["acf46b7a.f84c88"],"x":605,"y":3800,"wires":[]}]

```

It has a `delay` in just to make it _traceable_. You can delete the node if you want.

For the basics, does that do what you want, or do you also need 10 _outputs_?  
If so, they could be taken after the `step` node before the `link out` node.

If that is good, we can build on it.

I think I stated above the valve needed to be operated. I think that implies an on/off operation...

Boy you guys are making it hard on me to get the pump operational before 4th of July so I can shoot a mach 4.5 Marshmallow for the worlds record...I think it will push out to 2021.. Have to post last years video again this year. PVC doesn't hold up to Mach 4.5 Velocities even though the pressure was only 50 PSI...

And yes, stand in its way and it would kill you...Death by Marshmallow.....

I like the link nodes was planning on using MQTT in part of it to pass stuff to differing raspberry pi units.

setting global.charge and utilizing it would seem to be better for the overall "Recipe"

```

You need to set where the `slider` is.

Things to note:  
The _valve_ needs to be turned `ON` and `OFF` to shoot a marshmallow. I don't think leaving it always `ON` will work.

Look at the `DONE` node and that is the _signal_ that will be sent to the solenoid / valve.  
Really it should be a `true` and `false` or `1` and `0`. But I hope you can do that.

That is a WHOLE OTHER set of variables that need to be declared **before** now.

Again, I know how to set up what you guys are showing me, but I can't get ui\_numeric as the node to set the starting count.

ui\_numeric passes a message each time I increment the count...Bad for your loops, and when I need to set 1500...Ugh

I need the functionality of ui\_numeric to let me set it and then to poke it when called to pass its count.

```

That starts the loop and counts down.

Change the values from 1 to 50 to 1 to 1500... 1,00,000,000 if you really must.

I **decrement** the counter so it stops at `0`. A lot easier.

I need ui\_numeric not ui\_slider

Maybe ui\_numeric needs to be rethought a bit.

Ain't rocket science.  
Well, it is (seemingly) marshmallow science.

Actually...It is rocket science. Hypersonic Pulse Detonation and it solves the thermal issues. Mine operates silently at room temperature. And its logarithmic not linear in the charge to pressure..No one in the world other than I and my PhD Chemist father-in-law understand it...

Again. trying to slip in anything but ui\_numeric...

You guys are going to force me to write my loops in Python Function...Aren't you....
