Hello. I have a new build where I use the Ultitube 150 Pro and Octo (control all fans). I don't have a water temperature sensor connected via the Octo. I only have water temperature data via the D5 Next. I like to use the water temperature to control my fan curve. On my other build I connected the Octo to the AQ6 to do setups which was easy, however, I can't connect the Octo to the D5 Next like I did with the AQ6. I planned to install the High Flow 2 but no one had them in stock when I did my purchases. I will make change in the future, but for now I need this temporary fix.

How can I use the water temperature data from the D5 next as the data source to setup my fan curve in the Octo? I created a Soft Sensor in the Octo for the D5 temp sensor as a data source in Octo but I don't see it as a data source in the fan curve option so am stuck at this point. I'll keep chugging away trying to figure this out and hopefully someone chimes in and puts me on the right path.

Thanks...Al

Hey Aquaman thanks for the reply. I am trying to use the Octo to control fan curve and not the D5 pump. I have no fans connected to the D5 Next. I need to use the D5 next water temperature data in the Octo to set up my fan curve.

I have a feeling that I need to setup via the playground which I am not familiar with but there's an older thread out there on this. I will have to find it and use it for reference.

NVM. I found and ordered the High Flow 2. All is good. The fan curve is up and running.
