Hi Trystan
Thank you for getting in touch.
Just so I understand. I should try and connect the Red Out1 to the ADC input and then a pull up (or down?) resistor between the 3.3V and the ADC as I have drawn? What resistor, 10K?
Apart from this last hurdle, I have all the CT monitors and temperature probes installed, and I’m just building the charts and displays to show the heat pump, solar and battery performance. The EmonPi2 and Emoncms, etc, is very good.
I have spoken to DMS https://www.dmsltd.com/ and they have advised that I can’t just change the head. I think that is because the head is calibrated to the flow meter, but not sure (I’m still not convinced it’s set up for the glycol mix we have. The installer hasn’t been very helpful since I started asking detailed questions. So the output might be junk anyway). If there is a way to change it then I’d be up for it, although it’s a sealed unit, it’s only for my information (i.e. not RHI).
Kind regards
Paul
