This looks very interesting!
What output is there on the CAT5 cable? If I wanted to write my own software just using a Raspberry Pi and this, how feasible/practical is it to read the temps and drive the servo/blower without the HM? Is it possible to wire up the CAT5 on the pi end to the GPIO...
Has anyone any experience using the offset rotary damper with this blower - http://www.farnell.com/datasheets/35129.pdf ? It looks like it should fit (the exhaust is 0.2mm otherwise it's about the same)? The one I can't find the Delta one Tom linked to anywhere in the UK.
Tom - have you any...
Bryan, sounds great. Count me in for one of these too please. It's about time I went ahead and built a heatermeter after reading about them for so long!
