Hi all. I’ve had my altherma 3 running for a couple of years now,. Got Emoncms set up last year but finally this month resolved an issue with my outdoor temperature monitoring meaning the system has been approved on heatpumpmonitor.org. I am using the ESPAltherma hardware, plus a CT clamp on the feed to the heat pump. This is my system: HeatpumpMonitor.org
However, I’ve noticed there is a data flag issue, for “Temperature sensor offset errors” and I am wondering if anyone can help me resolve the issue so the flag can be removed. I have read a bit about it, and it appears that it’s possibly because the system is recording intermittent heat output when the compressor is not running (closer investigation suggests the circulation pump is starting, resulting in a flow and a small delta T, so the calculation for heat output is generating a heat output).
Any help or suggestions greatly appreciated.
