Dear Guys, I am new with node-red as well as JavaScript. I would like to make active a device for some percent of 1 second in 1000 ms (e.g. 60% of 1 second= 600ms) with high=1 and make the rest time (40% of 1000ms) inactive low=0. The flow shall be setting as a loop while the main button is true (…

Hi, I extended the flow by one range (instead of inject) and connected to device and tested. it works as I imagined it to be. I keep developing it. the flow looks like this: [{"id":"85a28ca5.288778","type":"range","z":"e01cd0e3.b9bbf8","minin":"0","maxin":"100","minout":"0","maxout":"1","action":"s…

Do you mean you want a Pulse Width Modulated output? If so then the best way to do it will depend on what device you are running node red.

The Puls Width Modulation (PWM) is applicable with analog outputs (AO). I need the flow for controlling of a digital output that accept the value 0 =0V or 1=24V. In this regards I thought I can set the message for a while of one second (1000ms) to 1 or 0. The main loop send input message periodic (…

No, pwm is for digital outputs.

I use 8 channel digital Input/out of Wago 750-1506. Information is avaiable under [ https://www.wago.com › io-systeme › 750-1506]( https://www.wago.com › io-systeme › 750-1506) This is not for pmw avaiable.

Hi, thanks a lot for your code. It seems very compact and effectively. I close it to my main flow and report about the result.

hi drmibell, I used your code in my flows. you see attached the complete flow. The flow functions, but not as I expect. I made some comment on some node to underestanding what I mean. In principle, the following conditions of flow are to be expected: flow sends message only if main switch is set…

remark: i made copy and paste the code. I hope it is workable! It's not. Export your flow again and post it like: ``` your code ```

[{"id":"e01cd0e3.b9bbf8","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"b10f794c.605748","type":"ui_slider","z":"e01cd0e3.b9bbf8","name":"Heater value 0..100%","label":"Heater value 0..100%","tooltip":"","group":"56943ca1.7f3dac","order":3,"width":"0","height":"0","passthru":true,"…
