Question about Events and Triggers

Community Help With My Project
1

Hi.

I have built my breadboard and added sensors and relay in Cayenne, It is a solar pool heating controller.

I have three thermometers and one relay.

I want the relay to turn on if the temperature of sensor 1 is 6c hotter than sensor 2, but cannot figure out how to do that,

Any advice would be appreciated.

Thanks

Hi Ashley,

This will be easier to accomplish when we’ve updated the triggers engine to allow things like executing custom code, multiple conditional statements, etc. But in the meantime I have an idea: Is your project with Arduino or Raspberry Pi? If you’re using Arduino, you could do the calculation in your sketch code, then pass the result that the trigger engine would need to care about to a virtual pin, then you could have Cayenne trigger based off of that result.

I can help you with the code if you let me know what the sketch file you’re currently using looks like.

Hello,
I have the same question as Ashley_Gibbon (Raspberry Pi), is planned an update of the triggers engine soon ?

Thanks
