I have a ventilation system with rotating heat recovery in my house.
It can recover about 70-80% of the energy in the air that is ventilated.
I would like to monitor what is happening. So i installed 4pcs of DS18B20 in the system.
I also installed on CT on the powerchord for the ventilator system, and the AC-AC adapter to monitor voltage.
I also have pulsecounter on the main utility meter.
-Incoming air temp C from outside (T1)
-Air temp C going into house after recovery (T2)
-Air temp C going out before recovery (T3)
-Air temp Cgoing out the chimeny (T4)
So, by taking the difference between (T3-T4) and (T3-T1) , and then dividing them (T3-T4) / (T3-T1) i can get the % of recovery in degress (not energy because of humidity beeing different).
I tried so many times to set up this in the EMON CMS but i cant get it to work.
How would i do this?
Very thankful for your input guys!
I am using the EmonPi with the SD card that came with it from the shop. System version 8.5, seems somewhat stripped from what i am used to on the emoncms.org website.
I also have problems getting the pulsecounter from my utilitymeter to show a normal POWER feed and a ENERGY feed.
