Hi there,
i would like to have a ‘wanted temperature’ slider or knob.
I can’t seem to find any information about this subject.
I only see the default trigger options ‘if temp is below, then,…’
any suggestions here?
Kind regards.
So you want to be able to change the temp setting without going into the triggers and changing those right? You could use a analog slider with your values and then use a “if/else” statement in your code. Do you have any code together we could see? Thanks
hi vapor83,
you mean adding a an analog virtualwrite to a esp chip?
I was thingking to do try this on my sonoff TH10.
But how can i make it work on a RPI? this way i cant build a rpi zero in a hottub and still make changes on the go. with an ESP is still have to use serial to upload the code?
I don’t know a lot about coding, so i tried cayenne because it is ‘drag and drop’
Here is my code for the sonoff. (my comments are in dutch and i’m guessing de rest is very messy :p)
Kind Regards!

here is a modified code that shows how to control a digital pin when the temp gets above or below the setting on the cayenne dashboard. It uses a analog slider on virtual pin 10. I hopefully this helps, let me know if you have questions.
