Hey @TrystanLea
So its been 3 years and i still get exactly 91% data quality throught, strangely regular rate of failure.
Any updates since back then? Hoping to get it working now.
Thanks
Hello @jbetech is this the original heat pump monitor board (HeatpumpMonitor/HeatpumpMonitorTH at master · openenergymonitor/HeatpumpMonitor · GitHub)? We discontinued development on that board Im afraid so I imagine you are likely to be still running the latest firmware for it. We moved to the approach of using a RaspberryPi with a MBUS and Modbus USB adapter instead, which allowed us to debug these kinds of issues and add support for more meters easier.
Looking at your debug notes above suggests that’s quite a timing variance, I wonder if that’s coming from timing on the Atmega328 side of things or from latency on the wifi/internet connection?
Have you tried resetting?
After 5 years, i finally spent the time to debug this.
Still using the original kit: https://github.com/openenergymonitor/HeatpumpMonitor/tree/master/HeatpumpMonitorTH
Conclusion, I had to disable the OEM_EMON_ENABLE.
Im not using the CT sensors, having it enabled was causing random delays in the script of 4+ seconds in the few mins i watched it, causing the transmissions to be delayed and missing the slots at the EMONCMS end i assume.
I had also previously reduced this from 9800 to 9000. Didnt help but left it set at this.
