I have two dropdowns on dashboard but when I select dropdown values it gets automatically starts. I want to start dropdown values on button click. How to achieve this functionality.

Your trigger node is missing settings, try updating your node-red as 1.06 is fairly old. [Screenshot_20210203-104818] Or try this work around for your old version [{"id":"e247997e.019898","type":"inject","z":"57675e72.26a0d8","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":…

You posted a screenshot showing a NaN error from a node called HM, but there does not appear to be such a node in the flow you posted. The other error is from a debug node but you have not given that node a name so we don't know which one it is. Please give debug nodes names. Please post just a sm…

i have two dropdown nodes... one for time selection (PICK THE TIME) dropdown and one for speed variation(KM/HR) dropdown... both dropdown values are given to raspberry pi pwm pin For speed variation and various trigger time i am using raspberry pi pwm pin [2021-01-29-184212_1920x1080_scrot] [{…

The error says, as I presume you know, that the gpio node has been given something that is Not a Number (NaN). Add debug nodes and work backwards up the flow until you find at which node the problem is arising. Then look at the inputs to that node and work out why that is happening. If you can't …

[2021-01-30-131602_1920x1080_scrot] i tried as you said , and got speed variation(KM/HR) dropdown value on gpio pwm pin. But its not getting trigger value time selection (PICK THE TIME) dropdown on gpio pwm pin.

Ok now we have a simpler flow and we can see the issue. you are passing on the object flow.start and not splitting it up again. i also added a better delay as no need for all those triggers and the switch node. [{"id":"1ad9dfd.a1875a","type":"change","z":"a2d9cfcc.919dd8","name":"","rules":[{"t":"s…

[2021-01-30-180304_1920x1080_scrot] Sorry for late reply... I tried your flow but nothing is showing in debug window and raspberry pi gpio pwm pin...

started [Screenshot_20210202-083848] 300 seconds later [Screenshot_20210202-084536] So you must have a setting wrong as yours shows reset. As i can tell nothing else from an image, you will need to post more info.

I have changed nothing in the flow given by you... I want to use both dropdown values simultaneously... i don't want delay... i want trigger time using dropdown with the speed of pwm gpio pin km/hrs... I am working on treadmill programming so what i actually want to do is :- first i want to do …

[image] sanket: I have changed nothing in the flow given by you... If this is true then the flow should work. Again with out info to look at i can tell nothing. I still await info i can use to help you. (maybe the flow and some debugs would help to see issue) [edit] to start at 30 for 300 …

I think maybe you do not know how to export the flow and paste it here. Select the nodes you wish to share and then select Export > Copy to Clipboard. Then see this post for how to post it here - How to share code or flow json.
