For the Venus GX, is there anyway to control the two relay outputs to start a fan based on the temperature sensor showing a high temperature (or at least one relay)?

Unfortunately, temperature dependant relay parameters are not available.

Thanks, hopefully this relay parameter for temperature conditions will be added soon. Seems like there is demand

I know that you now have a solution to move forward with, but if you are/were keen, you can easily achieve this with a Venus GX and Node-RED (internally or externally) or Modbus TCP - but nothing off the shelf/fully supported or formally released as yet.

As an example, this is a user interface screen I made up the other day with a Node-RED dashboard - the switches at the bottom directly control the 2x Venus GX relays;

Anyway.. all the best and have fun! :-)

If I could program the Venus GX to switch the relays based on temperature that would be ideal. While I am computer savvy, Red-node does not seem straightforward. Is there a step-by-step guide for newbies for this kind of programming ?

I decided to use a 12vdc temp controller for $11.00
